Subpart A – Definitions
§ 105.5 Definitions.
(a) This part contains the definitions for certain words and phrases used throughout this subchapter (49 CFR parts 105 through 110). At the beginning of each subpart, the Pipeline and Hazardous Materials Safety Administration (“PHMSA” or “we”) will identify the defined terms that are used within the subpart – by listing them – and refer the reader to the definitions in this part. This way, readers will know that PHMSA has given a term a precise meaning and will know where to look for it.
(b) Terms used in this part are defined as follows:
Approval means a written authorization, including a competent authority approval, issued by the Associate Administrator, the Associate Administrator’s designee, or as otherwise prescribed in the HMR, to perform a function for which prior authorization by the Associate Administrator is required under subchapter C of this chapter (49 CFR parts 171 through 180).
Associate Administrator means Associate Administrator for Hazardous Materials Safety, Pipeline and Hazardous Materials Safety Administration.
Competent Authority means a national agency that is responsible, under its national law, for the control or regulation of some aspect of hazardous materials (dangerous goods) transportation. Another term for Competent Authority is “Appropriate authority” which is used in the International Civil Aviation Organization’s (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air. The Associate Administrator is the United States Competent Authority for purposes of 49 CFR part 107.
Competent Authority Approval means an approval by the competent authority that is required under an international standard (for example, the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air and the International Maritime Dangerous Goods Code). Any of the following may be considered a competent authority approval if it satisfies the requirement of an international standard:
(1) A specific regulation in subchapter A or C of this chapter.
(2) A special permit or approval issued under subchapter A or C of this chapter.
(3) A separate document issued to one or more persons by the Associate Administrator.
Federal hazardous material transportation law means 49 U.S.C. 5101 et seq.
File or Filed means received by the appropriate PHMSA or other designated office within the time specified in a regulation or rulemaking document.
Hazardous material means a substance or material that the Secretary of Transportation has determined is capable of posing an unreasonable risk to health, safety, and property when transported in commerce, and has designated as hazardous under section 5103 of Federal hazardous materials transportation law (49 U.S.C. 5103). The term includes hazardous substances, hazardous wastes, marine pollutants, elevated temperature materials, materials designated as hazardous in the Hazardous Materials Table (see 49 CFR 172.101), and materials that meet the defining criteria for hazard classes and divisions in part 173 of subchapter C of this chapter.
Hazardous Materials Regulations or HMR means the regulations at 49 CFR parts 171 through 180.
Indian tribe has the same meaning given that term in section 4 of the Indian Self-Determination and Education Assistance Act (25 U.S.C. 450b).
Person means an individual, firm, copartnership, corporation, company, association, or joint-stock association (including any trustee, receiver, assignee, or similar representative); or a government or Indian tribe (or an agency or instrumentality of any government or Indian tribe) that transports a hazardous material to further a commercial enterprise or offers a hazardous material for transportation in commerce. Person does not include the following:
(1) The United States Postal Service.
(2) Any agency or instrumentality of the Federal government, for the purposes of 49 U.S.C. 5123 (civil penalties) and 5124 (criminal penalties).
(3) Any government or Indian tribe (or an agency or instrumentality of any government or Indian tribe) that transports hazardous material for a governmental purpose.
Political subdivision means a municipality; a public agency or other instrumentality of one or more States, municipalities, or other political body of a State; or a public corporation, board, or commission established under the laws of one or more States.
Preemption determination means an administrative decision by the Associate Administrator that Federal hazardous materials law does or does not void a specific State, political subdivision, or Indian tribe requirement.
Regulations issued under Federal hazardous material transportation law include this subchapter A (parts 105-110) and subchapter C (parts 171-180) of this chapter, certain regulations in chapter I (United States Coast Guard) of title 46, Code of Federal Regulations, and in chapters III (Federal Motor Carrier Safety Administration) and XII (Transportation Security Administration) of subtitle B of this title, as indicated by the authority citations therein.
Special permit means a document issued by the Associate Administrator, the Associate Administrator’s designee, or as otherwise prescribed in the HMR, under the authority of 49 U.S.C. 5117 permitting a person to perform a function that is not otherwise permitted under subchapter A or C of this chapter, or other regulations issued under 49 U.S.C. 5101 et seq. (e.g., Federal Motor Carrier Safety routing requirements).
State means a State of the United States, the District of Columbia, the Commonwealth of Puerto Rico, the Commonwealth of the Northern Mariana Islands, the Virgin Islands, American Samoa, Guam, or any other territory or possession of the United States designated by the Secretary.
Transports or Transportation means the movement of property and loading, unloading, or storage incidental to the movement.
Waiver of Preemption means a decision by the Associate Administrator to forego preemption of a non-Federal requirement – that is, to allow a State, political subdivision or Indian tribe requirement to remain in effect. The non-Federal requirement must provide at least as much public protection as the Federal hazardous materials transportation law and the regulations issued under Federal hazardous materials transportation law, and may not unreasonably burden commerce.

Subpoenas
§ 105.45 Issuing a subpoena.
(a) Subpoenas explained. A subpoena is a document that may require you to attend a proceeding, produce documents or other physical evidence in your possession or control, or both. PHMSA may issue a subpoena either on its initiative or at the request of someone participating in a proceeding. Anyone who requests that PHMSA issue a subpoena must show that the subpoena seeks information that will materially advance the proceeding.
(b) Attendance and mileage expenses. (1) If you receive a subpoena to attend a proceeding under this part, you may receive money to cover attendance and mileage expenses. The attendance and mileage fees will be the same as those paid to a witness in a proceeding in the district courts of the United States.
(2) If PHMSA issues a subpoena to you based upon a request, the requester must serve a copy of the original subpoena on you, as required in § 105.50. The requester must also include attendance and mileage fees with the subpoena unless the requester asks PHMSA to pay the attendance and mileage fees because of demonstrated financial hardship and PHMSA agrees to do so.
(3) If PHMSA issues a subpoena at the request of an officer or agency of the Federal government, the officer or agency is not required to include attendance and mileage fees when serving the subpoena. The officer or agency must pay the fees before you leave the hearing at which you testify.

If PHMSA issues a subpoena to an entity, rather than an individual, personal service is made by delivering the subpoena and fees to the entity’s registered agent for service of process or to any officer, director or agent in charge of any of the entity’s offices.
(b) Service by mail. You may be served with a copy of a subpoena and fees by certified or registered mail at your last known address. Service of a subpoena and fees may also be made by registered or certified mail to your agent for service of process or any of your representatives at that person’s last known address.
(c) Other methods. You may be served with a copy of a subpoena by any method where you receive actual notice of the subpoena and receive the fees before leaving the hearing at which you testify.
(d) Filing after service. After service is complete, the individual who served a copy of a subpoena and fees must file the original subpoena and a certificate of service with the PHMSA official who is responsible for conducting the hearing.
§ 105.55 Refusal to obey a subpoena.
(a) Quashing or modifying a subpoena. If you receive a subpoena, you can ask PHMSA to overturn (“quash”) or modify the subpoena within 10 days after the subpoena is served on you. Your request must briefly explain the reasons you are asking for the subpoena to be quashed or modified. PHMSA may then do the following:
(1) Deny your request.
(2) Quash or modify the subpoena.
(3) Grant your request on the condition that you satisfy certain specified requirements.

PART 106 – RULEMAKING PROCEDURES
Subpart A – PHMSA Rulemaking Documents
§ 106.5 Defined terms used in this subpart.
The following defined terms (see part 105, subpart A, of this subchapter) appear in this subpart: File; Person; State.
§ 106.10 Process for issuing rules.
(a) PHMSA (“we”) uses informal rulemaking procedures under the Administrative Procedure Act (5 U.S.C. 553) to add, amend, or delete regulations. To propose or adopt changes to a regulation, PHMSA may issue one or more of the following documents. We publish the following rulemaking documents in the
(1) An advance notice of proposed rulemaking.
(2) A notice of proposed rulemaking.
(3) A final rule.
(4) An interim final rule.
(5) A direct final rule.
(b) Each of the rulemaking documents in paragraph (a) of this section generally contains the following information:
(1) The topic involved in the rulemaking document.
(2) PHMSA’s legal authority for issuing the rulemaking document.
(3) How interested persons may participate in the rulemaking proceeding (for example, by filing written comments or making oral presentations).
(4) Whom to call if you have questions about the rulemaking document.
(5) The date, time, and place of any public meetings being held to discuss the rulemaking document.
(6) The docket number and regulation identifier number (RIN) for the rulemaking proceeding.
§ 106.15 Advance notice of proposed rulemaking.
An advance notice of proposed rulemaking (ANPRM) tells the public that PHMSA is considering an area for rulemaking and requests written comments on the appropriate scope of the rulemaking or on specific topics. An advance notice of proposed rulemaking may or may not include the text of potential changes to a regulation.
§ 106.20 Notice of proposed rulemaking.
A notice of proposed rulemaking (NPRM) contains PHMSA’s specific proposed regulatory changes for public comment and contains supporting information. It generally includes proposed regulatory text.
§ 106.25 Revising regulations without first issuing an ANPRM or NPRM.
PHMSA may add, amend, or delete regulations without first issuing an ANPRM or NPRM in the following situations:
(a) We may go directly to a final rule or interim final rule if, for good cause, we find that a notice of proposed rulemaking is impracticable, unnecessary, or contrary to the public interest. We must place that finding and a brief statement of the reasons for it in the final rule or interim final rule.
(b) We may issue a direct final rule (see § 106.40).
§ 106.30 Final rule.
A final rule sets out new regulatory requirements and their effective date. A final rule will also identify issues raised by commenters in response to the notice of proposed rulemaking and give the agency’s response.
§ 106.35 Interim final rule.
An interim final rule is issued without first issuing a notice of proposed rulemaking and accepting public comments and sets out new regulatory requirements and their effective date. PHMSA may issue an interim final rule if it finds, for good cause, that notice and public procedure are impracticable, unnecessary, or contrary to the public interest. PHMSA will clearly set out this finding in the interim final rule. After receiving and reviewing public comments, as well as any other relevant documents, PHMSA may revise the interim final rule and then issue a final rule.
§ 106.40 Direct final rule.
A direct final rule makes regulatory changes and states that the regulatory changes will take effect on a specified date unless PHMSA receives an adverse comment within the comment period – generally 60 days after the direct final rule is published in the
(a) Actions taken by direct final rule. We may use direct final rulemaking procedures to issue rules that do any of the following:
(1) Make minor substantive changes to regulations.
(2) Incorporate by reference the latest edition of technical or industry standards.
(3) Extend compliance dates.
(4) Make noncontroversial changes to regulations. We must determine and publish a finding that use of direct final rulemaking, in this situation, is in the public interest and unlikely to result in adverse comment.
(b) Adverse comment. An adverse comment explains why a rule would be inappropriate, or would be ineffective or unacceptable without a change. It may challenge the rule’s underlying premise or approach. Under the direct final rule process, we do not consider the following types of comments to be adverse:
(1) A comment recommending another rule change, in addition to the change in the direct final rule at issue, unless the commenter states why the direct final rule would be ineffective without the change.
(2) A frivolous or irrelevant comment.
(c) Confirmation of effective date. We will publish a confirmation document in the
(d) Withdrawing a direct final rule. (1) If we receive an adverse comment, we will either publish a document withdrawing the direct final rule before it becomes effective and may issue an NPRM, or proceed by any other means permitted under the Administrative Procedure Act.
(2) If we withdraw a direct final rule because of an adverse comment, we may incorporate the adverse comment into a later direct final rule or may publish a notice of proposed rulemaking.
(e) Appeal. You may appeal PHMSA’s issuance of a direct final rule (see § 106.115) only if you have previously filed written comments (see § 106.60) to the direct final rule.
§ 106.45 Tracking rulemaking actions.
The following identifying numbers allow you to track PHMSA’s rulemaking activities:
(a) Docket number. We assign an identifying number, called a docket number, to each rulemaking proceeding. Each rulemaking document that PHMSA issues in a particular rulemaking proceeding will display the same docket number. This number allows you to do the following:

If he does not dismiss it in whole, he issues an order directing compliance or assessing a civil penalty, or, if proposed in the notice, both.
§ 107.319 Request for a hearing.
(a) In responding to a notice of probable violation under § 107.311, the respondent may request a formal administrative hearing on the record before an Administrative Law Judge (ALJ) obtained by the Office of the Chief Counsel.
(b) A request for a hearing under paragraph (a) of this section must:
(1) State the name and address of the respondent and of the person submitting the request if different from the respondent;
(2) State which allegations of violations, if any, are admitted; and
(3) State generally the issues to be raised by the respondent at the hearing. Issues not raised in the request are not barred from presentation at the hearing; and
(4) Be addressed to the official who issued the notice.
(c) After a request for a hearing that complies with the requirements of paragraph (b) of this section, the Chief Counsel obtains an ALJ to preside over the hearing and notifies the respondent of this fact. Upon assignment of an ALJ, further matters in the proceeding generally are conducted by and through the ALJ, except that the Chief Counsel and respondent may compromise or settle the case under § 107.327 of this subpart without order of the ALJ or voluntarily dismiss the case under Rule 41(a)(1) of the Federal Rules of Civil Procedure without order of the ALJ; in the event of such a compromise, settlement or dismissal, the Chief Counsel expeditiously will notify the ALJ thereof.
(d) At any time after requesting a formal administrative hearing but prior to the issuance of a decision and final order by the ALJ, the respondent may withdraw such request in writing, thereby terminating the jurisdication of the ALJ in the case. Such a withdrawal constitutes an irrevocable waiver of respondent’s right to such a hearing on the facts, allegations, and proposed sanction presented in the notice of probable violation to which the request for hearing relates.
§ 107.321 Hearing.
(a) To the extent practicable, the hearing is held in the general vicinity of the place where the alleged violation occurred or at a place convenient to the respondent. Testimony by witnesses shall be given under oath and the hearing shall be recorded verbatim.
(b) Hearings are conducted in accordance with the Federal Rules of Evidence and Federal Rules of Civil Procedure; however, the ALJ may modify them as he determines necessary in the interest of a full development of the facts. In addition, the ALJ may:
(1) Administer oaths and affirmations;
(2) Issue subpoenas as provided by § 105.45;
(3) Adopt procedures for the submission of motions, evidence, and other documents pertinent to the proceeding;
(4) Take or cause depositions to be taken;
(5) Rule on offers of proof and receive relevant evidence;
(6) Examine witnesses at the hearing;
(7) Convene, recess, reconvene, adjourn and otherwise regulate the course of the hearing;

(d) The respondent may appear and be heard on his own behalf or through counsel of his choice. The respondent or his counsel may offer relevant information including testimony which he believes should be considered in opposition to the allegations or which may bear on the sanction being sought and conduct such cross-examination as may be required for a full disclosure of the facts.
§ 107.323 ALJ’s decision.
(a) After consideration of all matters of record in the proceeding, the ALJ shall issue an order dismissing the notice of probable violation in whole or in part or granting the sanction sought by the Office of Chief Counsel in the notice. If the ALJ does not dismiss the notice of probable violation in whole, he issues an order directing compliance or assessing a civil penalty, or, if proposed in the notice, both. The order includes a statement of the findings and conclusions, and the reasons therefore, on all material issues of fact, law, and discretion.
(b) If, within 20 days of receipt of an order issued under paragraph (a) of this section, the respondent does not submit in writing his acceptance of the terms of an order directing compliance, or, where appropriate, pay a civil penalty, or file an appeal under § 107.325, the case may be referred to the Attorney General with a request that an action be brought in the appropriate United States District Court to enforce the terms of a compliance order or collect the civil penalty.
§ 107.325 Appeals.
(a) Hearing proceedings. A party aggrieved by an ALJ’s decision and order issued under § 107.323, may file a written appeal in accordance with paragraph (c) of this section with the Administrator, Office of the Administrator, Pipeline and Hazardous Materials Safety Administration, East Building, 1200 New Jersey Avenue, SE., Washington, DC 20590-0001.
(b) Non-Hearing proceedings. A respondent aggrieved by an order issued under § 107.317, may file a written appeal in accordance with paragraph (c) of this section with the Administrator, Office of the Administrator, Pipeline and Hazardous Materials Safety Administration, East Building, 1200 New Jersey Avenue, SE., Washington, DC 20590-0001.
(c) An appeal of an order issued under this subpart must:
(1) Be filed within 20 days of receipt of the order by the appealing party; and
(2) State with particularity the findings in the order that the appealing party challenges, and include all information and arguments pertinent thereto.
(d) If the Administrator, PHMSA, affirms the order in whole or in part, the respondent must comply with the terms of the decision within 20 days of the respondent’s receipt thereof, or within the time prescribed in the order. If the respondent does not comply with the terms of the decision within 20 days of receipt, or within the time prescribed in the order, the case may be referred to the Attorney General for action to enforce the terms of the decision.
(e) The filing of an appeal stays the effectiveness of an order issued under § 107.317 or § 107.323. However, if the Administrator, PHMSA, determines that it is in the public interest, he may keep an order directing compliance in force pending appeal.
§ 107.327 Compromise and settlement.
(a) At any time before an order issued under § 107.317 or § 107.323 is referred to the Attorney General for enforcement, the respondent or the Office of Chief Counsel may propose a compromise as follows:
(1) In civil penalty cases, the respondent or Chief Counsel may offer to compromise the amount of the penalty by submitting an offer for a specific amount to the other party. An offer of compromise by the respondent shall be submitted to the Chief Counsel who may, after consultation with the Associate Administrator, accept or reject it.
(i) A compromise offer stays the running of any response period then outstanding.
(ii) If a compromise is agreed to by the parties, the respondent is notified in writing. Upon receipt of payment by Office of Chief Counsel, the respondent is notified in writing that acceptance of payment is in full satisfaction of the civil penalty proposed or assessed, and Office of Chief Counsel closes the case with prejudice to the respondent.
(iii) If a compromise cannot be agreed to, the respondent is notified in writing and is given 10 days or the amount of time remaining in the then outstanding response period, whichever is longer, to respond to whatever action was taken by the Office of Chief Counsel or the Administrator, PHMSA.
(2) In compliance order cases, the respondent may propose a consent agreement to the Chief Counsel. If the Chief Counsel accepts the agreement, he issues an order in accordance with its terms. If the Chief Counsel rejects the agreement, he directs that the proceeding continue. An agreement submitted to the Chief Counsel must include:
(i) A statement of any allegations of fact which the respondent challenges;
(ii) The reasons why the terms of a compliance order or proposed compliance order are or would be too burdensome for the respondent, or why such terms are not supported by the record in the case;
(iii) A proposed compliance order suitable for issuance by the Chief Counsel;
(iv) An admission of all jurisdictional facts; and
(v) An express waiver of further procedural steps and all right to seek judicial review or otherwise challenge or contest the validity of the order.
(b) Notwithstanding paragraph (a)(1) of this section, the respondent or Office of Chief Counsel may propose to settle the case. If the Chief Counsel agrees to a settlement, the respondent is notified and the case is closed without prejudice to the respondent.

The baseline penalty amounts in Part II are used as a starting amount or range appropriate for the normal or typical nature, extent, circumstances, and gravity of the probable violations frequently cited in enforcement reports. PHMSA must also consider any additional factors, as provided in 49 U.S.C. 5123(c) and 49 CFR 107.331, including the nature, circumstances, extent and gravity of a violation, the degree of culpability and compliance history of the respondent, the financial impact of the penalty on the respondent, and other matters as justice requires. Consequently, at each stage of the administrative enforcement process, up to and including issuance of a final order or decision on appeal, PHMSA can adjust the baseline amount in light of the specific facts and circumstances of each case.
As part of this analysis, PHMSA reviews the factors outlined in the next section, Miscellaneous Factors Affecting Penalty Amounts, the safety implications of the violation, the pervasiveness of the violation, and all other relevant information. PHMSA considers not only what happened as a result of the violation, but also what could have happened as a result of continued violation of the regulations. As a general matter, one or more specific instances of a violation are presumed to reflect a respondent’s general manner of operations, rather than isolated occurrences.
PHMSA may draw factors relevant to the statutory considerations from the initial information gathered by PHMSA’s Office of Hazardous Materials Safety Field Operations, the respondent in response to an exit briefing, ticket, or Notice of Probable Violation (NOPV), or information otherwise available to us. We will generally apply the specific statutory factors that are outlined in the next section, Miscellaneous Factors Affecting Penalty Amounts, in the following order:
1. Select the appropriate penalty amount within a specific baseline or range, with appropriate increases or decreases depending on the packing group or material involved and other information regarding the frequency or duration of the violation, the culpability of the respondent, and the actual or potential consequences of the violation.
2. Apply decreases for a reshipper or carrier that reasonably relied on an offeror’s non-compliant preparation of a hazardous materials shipment.
3. Apply increases for multiple counts of the same violation.
4. Apply increases for prior violations of the HMR within the past six years.
5. Apply decreases for corrective actions.
6. Apply decreases for respondent’s inability to pay or adverse effect on its ability to continue in business.
A person who either receives hazardous materials from another company and reships them (reshipper), or accepts a hazardous material for transportation, and transports that material (carrier), is responsible for ensuring that the shipment complies in all respects with Federal hazardous materials transportation law. In both cases, the reshipper or carrier independently may be subject to enforcement action if the shipment does not comply.
Depending on all the circumstances, however, the person who originally prepared the shipment and placed it into transportation may have greater culpability for the noncompliance than the reshipper or carrier who reasonably relies on the shipment as received and does not open or alter the package before the shipment continues in transportation. PHMSA will consider the specific knowledge and expertise of all parties, as well as which party is responsible for compliance under the regulations, when evaluating the culpability of a reshipper or carrier. PHMSA recognizes that a reshipper or carrier may have reasonably relied upon information from the original shipper and may reduce the applicable baseline penalty amount up to 25 percent.
A main objective of PHMSA’s enforcement program is to obtain compliance with the HMR and the correction of violations which, in many cases, have been part of a company’s regular course of business. As such, there may be multiple instances of the same violation. Examples include a company shipping various hazardous materials in the same unauthorized packaging, shipping the same hazardous material in more than one type of unauthorized packaging, shipping hazardous materials in one or more packagings with the same marking errors, or using shipping papers with multiple errors.
Under the Federal hazmat law, 49 U.S.C. 5123(a), each violation of the HMR and each day of a continuing violation (except for violations relating to packaging manufacture or qualification) is subject to a civil penalty of up to $84,425 or $196,992 for a violation occurring on or after May 3, 2021. As such, PHMSA generally will treat multiple occurrences that violate a single regulatory provision as separate violations and assess the applicable baseline penalty for each distinct occurrence of the violation. PHMSA will generally consider multiple shipments or, in the case of package testers, multiple package designs, to be multiple occurrences; and each shipment or package design may constitute a separate violation.
PHMSA, however, will exercise its discretion in each case to determine the appropriateness of combining into a single violation what could otherwise be alleged as separate violations and applying a single penalty for multiple counts or days of a violation, increased by 25 percent for each additional instance, as directed by 49 U.S.C. 5123(c). For example, PHMSA may treat a single shipment containing three items or packages that violate the same regulatory provision as a single violation and apply a single baseline penalty with a 50 percent increase for the two additional items or packages; and PHMSA may treat minor variations in a package design for a package tester as a single violation and apply a single baseline penalty with a 25 percent increase for each additional variation in design.
When aggravating circumstances exist for a particular violation, PHMSA may handle multiple instances of a single regulatory violation separately, each meriting a separate baseline or increase the civil penalty by 25 percent for each additional instance. Aggravating factors may include increased safety risks, continued violation after receiving notice, or separate and distinct acts. For example, if the multiple occurrences each require their own distinct action, then PHMSA may count each violation separately (e.g., failure to obtain approvals for separate fireworks devices).
The baseline penalty in the List of Frequently Cited Violations assumes an absence of prior violations. If a respondent has prior violations of the HMR, generally, PHMSA will increase a proposed penalty.
When setting a civil penalty, PHMSA will review the respondent’s compliance history and determine if there are any finally-adjudicated violations of the HMR initiated within the previous six years. Only cases or tickets that have been finally-adjudicated will be considered (i.e., the ticket has been paid, a final order has been issued, or all appeal remedies have been exhausted or expired). PHMSA will include prior violations that were initiated within six years of the present case; a case or ticket will be considered to have been initiated on the date of the exit briefing for both the prior case and the present case. If multiple cases are combined into a single Notice of Probable Violation or ticket, the oldest exit briefing will be used to determine the six-year period. If a situation arises where no exit briefing is issued, the date of the Notice of Probable Violation or Ticket will be used to determine the six-year period. PHMSA may consider prior violations of the Hazardous Materials Regulations from other DOT Operating Administrations.
The general standards for increasing a baseline proposed penalty on the basis of prior violations are as follows:
1. For each prior civil or criminal enforcement case – 25 percent increase over the pre-mitigation recommended baseline penalty.
2. For each prior ticket – 10 percent increase over the pre-mitigation recommended baseline penalty.
3. If a respondent is cited for operating under an expired special permit and previously operated under an expired special permit (as determined in a finally-adjudicated civil, criminal, or administrative enforcement case or a ticket), PHMSA will increase the civil penalty 100 percent.
4. If a respondent is cited for the exact same violation that it has been previously cited for within the six-year period (in a finally-adjudicated civil, criminal, or administrative enforcement case or a ticket), PHMSA will increase the baseline for that violation by 100 percent. This increase will apply only when the present violation is identical to the previous violation and applies only to the specific violation that has recurred.
5. A baseline proposed penalty (both for each individual violation and the combined total) will not be increased more than 100 percent on the basis of prior violations.
PHMSA may lower a proposed penalty when a respondent’s documented corrective action has fixed an alleged violation. Corrective action should demonstrate not only that the specific deficiency is corrected but also that any systemic corrections have been addressed to prevent recurrence of the violation.
The two primary factors that determine the reduction amount are the extent and timing of the corrective action. In other words, PHMSA will determine the amount of mitigation based on how much corrective action a respondent completes and how soon after the exit briefing it performs corrective action. Comprehensive systemic action to prevent future violations may warrant greater mitigation than actions that simply target violations identified during the inspection. Actions taken immediately (within the 30 calendar day period that respondents have to respond to an exit briefing, or upon approval of Field Operations) may warrant greater mitigation than actions that are not taken promptly.
PHMSA may consider a respondent’s corrective action to assess mitigation at various stages in the enforcement process, including: (1) AFTEr an inspection and before an NOPV is issued; (2) on receipt of an NOPV; or (3) after receipt of an NOPV. In order to reduce a civil penalty for corrective action, PHMSA must receive satisfactory documentation that demonstrates the corrective action was completed. If a corrective action is of a type that cannot be documented (e.g., no longer using a particular packaging), then a respondent may provide a signed affidavit describing the action it took. The affidavit must begin with the affirmative oath “I hereby affirm under the penalties of perjury that the below statements are true and correct to the best of my knowledge, information and belief,” in accordance with 28 U.S.C. 1746.
Generally, corrective action credit may not exceed 25 percent. Mitigation is applied to individual violations and fact patterns but should not be considered to be automatic reduction. Thus, in a case with two violations, if corrective action for the first violation is more extensive than for the second, the penalty for the first will be mitigated more than that for the second. If a respondent has previously committed the same violation, however, as determined in a finally-adjudicated civil, criminal, or administrative enforcement case or a ticket, PHMSA will not apply any reduction for corrective action.
In determining the appropriate civil penalty reduction, PHMSA will consider the extent to which the respondent corrected the violation and any risks or harms it created, the respondent’s actions to prevent the violation from recurring, improvements to overall company practices to address a widespread compliance issue, and how quickly the corrective action was performed. In general, PHMSA will apply the following reductions for corrective action, subject to the facts and circumstances of individual cases and respondents. If a respondent has given full documentation of timely corrective action and PHMSA does not believe that anything else can be done to correct the violation or improve overall company practices, we will generally reduce the civil penalty by no more than 25 percent. As noted above, a 25 percent reduction is not automatic. We will reduce the penalty up to 20 percent when a respondent promptly and completely corrected the cited violation and has taken substantial steps toward comprehensive improvements. PHMSA will generally apply a reduction up to 15 percent when a respondent has made substantial and timely progress toward correcting the specific violation as well as overall company practices, but additional actions are needed. A reduction up to 10 percent is appropriate when a respondent has taken significant steps toward addressing the violation, but minimal or no steps toward correcting broader company policies to prevent future violations. PHMSA may reduce a penalty up to 5 percent when a respondent made untimely or minimal efforts toward correcting the violation.
PHMSA may mitigate a proposed penalty when a respondent documents that the penalty would either (1) exceed an amount that the respondent is able to pay, or (2) have an adverse effect on the respondent’s ability to continue in business. These criteria relate to a respondent’s entire business, and not just the product line or part of its operations involved in a violation. PHMSA may apply this mitigation by reducing the civil penalty or instituting a payment plan.
PHMSA will only mitigate a civil penalty based on financial considerations when a respondent supplies financial documentation demonstrating one of the factors above. A respondent may submit documentation of financial hardship at any stage to receive mitigation or an installment payment plan. Documentation includes tax records, a current balance sheet, profit and loss statements, and any other relevant records. Evidence of a respondent’s financial condition is used only to decrease a penalty, and not to increase it.
In evaluating the financial impact of a penalty on a respondent, PHMSA will consider all relevant information on a case-by-case basis. Although PHMSA will determine financial hardship and appropriate penalty adjustments on an individual basis, in general, we will consider the following factors.
1. The overall financial size of the respondent’s business and information on the respondent’s balance sheet, including the current ratio (current assets to current liabilities), the nature of current assets, and net worth (total assets minus total liabilities).
2. A current ratio close to or below 1.0 may suggest that the company would have difficulty in paying a large penalty or in paying it in a single lump sum.
3. A small amount of cash on hand (representing limited liquidity), even with substantial other current assets (such as accounts receivable or inventory), may suggest a company would have difficulty in paying a penalty in a single lump sum.
4. A small or negative net worth may suggest a company would have difficulty in paying a penalty in a single lump sum. Notwithstanding, many respondents have paid substantial civil penalties in installments even though net worth was negative. For this reason, negative net worth alone does not always warrant reduction of a proposed penalty or even, in the absence of factors discussed above, a payment plan.
When PHMSA determines that a proposed penalty poses a significant financial hardship, we may reduce the proposed penalty and/or implement an installment payment plan. The appropriateness of these options will depend on the circumstances of the case.
When an installment payment plan is appropriate, the length of the payment plan should be as short as possible, but may be adjusted as necessary. PHMSA will not usually exceed six months for a payment plan. In unusual circumstances, PHMSA may extend the period of a payment plan. For example, the duration of a payment plan may reflect fluctuations in a company’s income if its business is seasonal or if the company has documented specific reasons for current non-liquidity.

Appendix A to Part 107 – Standard Operating Procedures for Special Permits and Approvals
This appendix sets forth the standard operating procedures (SOPs) for processing an application for a special permit or an approval in conformance with 49 CFR parts 107 and 171 through 180. It is to be used by PHMSA for the internal management of its special permit and approval programs.
The words “special permit” and “approval” are defined in § 107.1. PHMSA receives applications for: (1) Designation as an approval or certification agency, (2) a new special permit or approval, renewal or modification of an existing special permit or an existing approval, (3) granting of party status to an existing special permit, and (4) in conformance with § 107.117, emergency processing for a special permit. Depending on the type of application, the SOP review process includes several phases, such as Completeness, Publication, Evaluation, and Disposition.
Special Permit and Approval Evaluation Review Process
| Special permit | Non-classification approval | Classification approval | Registration approval | |
|---|---|---|---|---|
| 1. Completeness | X | X | X | X |
| 2. Publication | X | |||
| 3. Evaluation | ||||
| a. Technical | X | X | X | |
| b. Safety Profile | X | X | X | |
| 4. Disposition | ||||
| a. Approval | X | X | X | X |
| b. Denial | X | X | X | X |
| c. Reconsideration/Appeal | X | X | X | X |
An approval for assessing an applicant’s ability to perform a function that does not involve classifying a hazardous material is described as a non-classification approval and certifies that: An approval holder is qualified to requalify, repair, rebuild, and/or manufacture cylinders stipulated in the HMR; an agency is qualified to perform inspections and other functions outlined in an approval and the HMR; an approval holder is providing an equivalent level of safety or safety that is consistent with the public interest in the transportation of hazardous materials outlined in the approval; and a radioactive package design or material classification fully complies with applicable domestic or international regulations. An approval for assessing the hazard class of a material is described as a classification approval and certifies that explosives, fireworks, chemical oxygen generators, self-reactive materials, and organic peroxides have been classed for manufacturing and/or transportation based on requirements stipulated in the HMR. Registration approvals include the issuance of a unique identification number used solely as an identifier or in conjunction with approval holder’s name and address, or the issuance of a registration number that is evidence the approval holder is qualified to perform an HMR-authorized function, such as visually requalifying cylinders. This appendix does not include registrations issued under 49 CFR part 107, subpart G.
1. Completeness. PHMSA reviews all special permit and approval applications to determine if they contain all the information required under § 107.105 (for a special permit), § 107.117 (for emergency processing) or § 107.402 (for designation as a certification agency) or § 107.705 (for an approval). If PHMSA determines an application does not contain all the information needed to evaluate the safety of the actions requested in the application, the Associate Administrator may reject the application. If the application is rejected, PHMSA will notify the applicant of the deficiencies in writing. An applicant may resubmit a rejected application as a new application, provided the newly submitted application contains the information PHMSA needs to make a determination.
Emergency special permit applications must comply with all the requirements prescribed in § 107.105 for a special permit application, and contain sufficient information to determine that the applicant’s request for emergency processing is justified under the conditions prescribed in § 107.117.
2. Publication. When PHMSA determines an application for a new special permit or a request to modify an existing special permit is complete and sufficient, PHMSA publishes a summary of the application in the
3. Evaluation. The evaluation phase consists of two assessments, which may be done concurrently, a technical evaluation and a safety profile evaluation. When applicable, PHMSA consults and coordinates its evaluation of applications with the following Operating Administrations (OAs) that share enforcement authority under Federal hazardous material transportation law: Federal Aviation Administration, Federal Motor Carrier Safety Administration, Federal Railroad Administration, and United States Coast Guard. PHMSA also consults other agencies with hazardous material subject-matter expertise, such as the Nuclear Regulatory Commission and the Department of Energy.
(a) Technical evaluation. A technical evaluation considers whether the proposed special permit or approval will achieve a level of safety at least equal to that required under the HMR or, if a required safety level does not exist, considers whether the proposed special permit is consistent with the public interest in that it will adequately protect against the risks to life and property inherent in the transportation of hazardous material. For a classification approval, the technical evaluation is a determination that the application meets the requirements of the regulations for issuance of the approval. If formal coordination with another OA is included as part of the evaluation phase, that OA is responsible for managing this process within the applicable OA. The OA reviews the application materials and PHMSA’s technical evaluation, and may provide their own evaluation, comments and recommendations. The OA may also recommend operational controls or limitations to be incorporated into the special permit or approval to improve its safety.
(b) Safety profile evaluation. Each applicant for a special permit or non-classification approval is subject to a safety profile evaluation to assess if the applicant is fit to conduct the activity authorized by the special permit or approval application. PHMSA will coordinate the safety profile evaluations with the appropriate OA if a proposed activity is specific to a particular mode of transportation, if the proposed activity will set new precedent or have a significant economic impact, or if an OA requests participation. PHMSA does not conduct initial safety profile reviews as part of processing classification approvals, which include fireworks, explosives, organic peroxides, and self-reactive materials. Additionally, cylinder approvals and certification agency approvals do not follow the same minimum safety profile review model.
(i) Automated Review. An applicant for a special permit or approval which requires a safety profile evaluation, but does not include coordination with an OA, is subject to an automated safety profile review. If the applicant passes the initial automated review, the applicant is determined to be fit. If the applicant fails the initial automated review, the applicant is subject to a safety profile evaluation. An applicant that fails a safety profile evaluation may be determined to be unfit. To begin this review, PHMSA or the applicant enters the applicant’s information into the web-based Hazardous Materials Information System (HMIS) or Hazmat Intelligence Portal (HIP), or other future application processing technology that provide an integrated information source to identify hazardous material safety trends through the analysis of incident and accident information, and provide access to comprehensive information on hazardous materials incidents, special permits and approvals, enforcement actions, and other elements that support PHMSA’s regulatory program. PHMSA then screens the applicant to determine if, within the four years prior to submitting its application, the applicant was involved in any incident attributable to the applicant or package where two or more triggers for a safety profile review or five or more triggers for on-site inspection enforcement case referral events occurred.
(1) The trigger events are listed in the following table:
| Trigger for safety profile review | Trigger for on-site inspection * |
|---|---|
| (1) Any incident that involved a death or injury; | (1) Evidence that an applicant is at risk of being unable to comply with the terms of an application, including those listed below. |
| (2) Two or more incidents involving a § 172.504(e) (placarding) Table 1 hazardous material; | (2) An on-site inspection at the recommendation of the fitness coordinator if the following criteria applies – Any incident listed under automated review in paragraph 3(b)(i) of this appendix is attributable to the applicant or package, other than driver error. |
| (3) Three or more incidents involving a bulk packaging, or an applicant that is acting as an interstate carrier of hazardous materials under the terms of the special permit or an approval; or | (3) If, during an inspection, evidence is found in the four years prior to submitting its application that an applicant has not implemented sufficient corrective actions for prior violations, or is at risk of being unable to comply with the terms of an application for a special permit or approval, an existing special permit or approval, or the HMR, then PHMSA will determine that the applicant is unfit to conduct the activities requested in an application or authorized special permit or approval. |
| (4) Any incident that involved: Incorrect package selection; leaking packages; not following closure instructions; failure to test packages, if applicable; and failure to secure packages, including incorrect blocking and/or bracing. | (4) Incorrect or missing: (a) Markings, (b) labels, (c) placards, or (d) shipping papers. |
* The Fitness Coordinator assesses and applies these triggers.
(2) If an applicant is acting as an interstate carrier of hazardous materials under the terms of the special permit, they will be screened in an automated manner based upon criteria established by FMCSA, such as that contained in its Safety and Fitness Electronic Records (SAFER) system, which consists of interstate carrier data, several states’ intrastate data, interstate vehicle registration data, and may include operational data such as inspections and crashes.
(ii) Safety profile evaluation. A fitness coordinator, as defined in § 107.1, conducts a safety profile evaluation of all applicants meeting any of the criteria listed earlier in this appendix under “automated review,” and all applicants whose safety profile evaluations are subject to coordination with an OA, as described in introductory paragraph 3(b) of this appendix. In a safety profile evaluation, PHMSA or the OA performs an in-depth evaluation of the applicant based upon items the automated review triggered concerning the applicant’s four-year performance and compliance history prior to the submission of the application. Information considered during this review may include the applicant’s history of prior violations, insufficient corrective actions, or evidence that the applicant is at risk of being unable to comply with the terms of an application for an existing special permit, approval, or the HMR. PHMSA performs the review or coordinates with the OAs, if necessary, if two or more modes of transportation are requested in the application, and coordinates this review with the OA(s) of the applicable mode(s). The applicable OA performs the review if one mode of transportation is requested in the application. If necessary, the fitness coordinator will attempt to contact the applicant for clarifying information. If the information provided is sufficient, an on-site inspection may not be necessary. After conducting an evaluation, if the fitness coordinator determines that the applicant may be unfit to conduct the activities requested in the application, the coordinator will forward the request and supporting documentation to PHMSA’s Field Operations Division, or a representative of the Department, such as an authorized Operating Administration representative, to perform an on-site inspection. After the safety profile evaluation is completed, if the applicant is not selected for an on-site inspection, the applicant is determined to be fit. On-site inspections are not required for fitness determinations from modal administrations according to their own procedures.
(iii) On-Site Inspection. (A) The factors in paragraph 3(b)(i) and 3(b)(ii) are used as evidence that an applicant is at risk of being unable to comply with the terms of an application, including those listed below. PHMSA’s Field Operations Division or representative of the Department, such as an Operating Administration representative, will conduct an on-site inspection at the recommendation of the fitness coordinator if one of the following criteria applies:
(1) Any incident listed under automated review in paragraph 3(b)(i) of this appendix is attributable to the applicant or package, other than driver error;
(2) Insufficient Corrective Actions, as defined in § 107.1, in any enforcement case for a period of four years prior to submitting the application, except when re-inspected with no violations noted; or
(3) Items noted by an IIA on a cylinder requalifier inspection report, except when re-inspected with no violations noted.
(B) If, during an inspection, the PHMSA investigator or a representative of the Department finds evidence in the four years prior to submitting its application that an applicant has not implemented sufficient corrective actions for prior violations, or is at risk of being unable to comply with the terms of an application for a special permit or approval, an existing special permit or approval, or the HMR, then PHMSA will determine that the applicant is unfit to conduct the activities requested in an application or authorized special permit or approval.
4. Disposition. (a) Special Permit. If an application for a special permit is issued, PHMSA provides the applicant, in writing, with a special permit and an authorization letter if party status is authorized.
(b) Approval. If an application for approval is issued, PHMSA provides the applicant, in writing, with an approval, which may come in various forms, including:
(1) An “EX” approval number for classifying an explosive (including fireworks; see §§ 173.56, 173.124, 173.128, and 173.168(a));
(2) A “RIN” (requalification identification number) to uniquely identify a cylinder requalification, repair, or rebuilding facility (see § 180.203);
(3) A “VIN” (visual identification number) to uniquely identify a facility that performs an internal or external visual inspection, or both, of a cylinder in conformance with 49 CFR part 180, subpart C, or applicable CGA Pamphlet or HMR provision;
(4) An “M” number for identifying packaging manufacturers (see § 178.3); or
(5) A “CA” (competent authority) for general approvals (see §§ 107.705, 173.185, and 173.230).
(c) Denial. An application for a special permit or approval may be denied in whole or in part. For example, if an application contains sufficient information to successfully complete its technical review but the Associate Administrator determines the applicant is unfit, the application will be denied. If an application for a special permit or an approval is denied, PHMSA provides the applicant with a brief statement, in writing, of the reasons for denial and the opportunity to request reconsideration (see §§ 107.113(g), 107.402, and 107.709(f)).
(d) Reconsideration and Appeal. (1) Special Permit. If an application for a special permit is denied, the applicant may request reconsideration as provided in § 107.123 and, if the reconsideration is denied, may appeal as provided in § 107.125. Applicants submitting special permit reconsiderations and appeals must do so in the same manner as new applications, provided the new submission is sufficiently complete to make a determination.
(2) Approval. If an application for an approval is denied, the applicant may request reconsideration as provided in § 107.715 and, if the reconsideration is denied, may appeal as provided in § 107.717. Applicants submitting approval reconsiderations and appeals must do so in the same manner as new applications, provided the new submission is sufficiently complete to make a determination.

SUBCHAPTER C – HAZARDOUS MATERIALS REGULATIONS
PART 171 – GENERAL INFORMATION, REGULATIONS, AND DEFINITIONS
Subpart A – Applicability, General Requirements, and North American Shipments
§ 171.1 Applicability of Hazardous Materials Regulations (HMR) to persons and functions.
Federal hazardous materials transportation law (49 U.S.C. 5101 et seq.) directs the Secretary of Transportation to establish regulations for the safe and secure transportation of hazardous materials in commerce, as the Secretary considers appropriate. The Secretary is authorized to apply these regulations to persons who transport hazardous materials in commerce. In addition, the law authorizes the Secretary to apply these regulations to persons who cause hazardous materials to be transported in commerce. The law also authorizes the Secretary to apply these regulations to persons who manufacture or maintain a packaging or a component of a packaging that is represented, marked, certified, or sold as qualified for use in the transportation of a hazardous material in commerce. Federal hazardous material transportation law also applies to anyone who indicates by marking or other means that a hazardous material being transported in commerce is present in a package or transport conveyance when it is not, and to anyone who tampers with a package or transport conveyance used to transport hazardous materials in commerce or a required marking, label, placard, or shipping description. Regulations prescribed in accordance with Federal hazardous materials transportation law shall govern safety aspects, including security, of the transportation of hazardous materials that the Secretary considers appropriate. In 49 CFR 1.53, the Secretary delegated authority to issue regulations for the safe and secure transportation of hazardous materials in commerce to the Pipeline and Hazardous Materials Safety Administrator. The Administrator issues the Hazardous Materials Regulations (HMR; 49 CFR parts 171 through 180) under that delegated authority. This section addresses the applicability of the HMR to packagings represented as qualified for use in the transportation of hazardous materials in commerce and to pre-transportation and transportation functions.
(a) Packagings. Requirements in the HMR apply to each person who manufactures, fabricates, marks, maintains, reconditions, repairs, or tests a packaging or a component of a packaging that is represented, marked, certified, or sold as qualified for use in the transportation of a hazardous material in commerce, including each person under contract with any department, agency, or instrumentality of the executive, legislative, or judicial branch of the Federal government who manufactures, fabricates, marks, maintains, reconditions, repairs, or tests a packaging or a component of a packaging that is represented, marked, certified, or sold as qualified for use in the transportation of a hazardous material in commerce.
(b) Pre-transportation functions. Requirements in the HMR apply to each person who offers a hazardous material for transportation in commerce, causes a hazardous material to be transported in commerce, or transports a hazardous material in commerce and who performs or is responsible for performing a pre-transportation function, including each person performing pre-transportation functions under contract with any department, agency, or instrumentality of the executive, legislative, or judicial branch of the Federal government. Pre-transportation functions include, but are not limited to, the following:
(1) Determining the hazard class of a hazardous material.
(2) Selecting a hazardous materials packaging.
(3) Filling a hazardous materials packaging, including a bulk packaging.
(4) Securing a closure on a filled or partially filled hazardous materials package or container or on a package or container containing a residue of a hazardous material.
(5) Marking a package to indicate that it contains a hazardous material.
(6) Labeling a package to indicate that it contains a hazardous material.
(7) Preparing a shipping paper.
(8) Providing and maintaining emergency response information.
(9) Reviewing a shipping paper to verify compliance with the HMR or international equivalents.
(10) For each person importing a hazardous material into the United States, providing the shipper with timely and complete information as to the HMR requirements that will apply to the transportation of the material within the United States.
(11) Certifying that a hazardous material is in proper condition for transportation in conformance with the requirements of the HMR.
(12) Loading, blocking, and bracing a hazardous materials package in a freight container or transport vehicle.
(13) Segregating a hazardous materials package in a freight container or transport vehicle from incompatible cargo.
(14) Selecting, providing, or affixing placards for a freight container or transport vehicle to indicate that it contains a hazardous material.
(c) Transportation functions. Requirements in the HMR apply to transportation of a hazardous material in commerce and to each person who transports a hazardous material in commerce, including each person under contract with any department, agency, or instrumentality of the executive, legislative, or judicial branch of the Federal government who transports a hazardous material in commerce. Transportation of a hazardous material in commerce begins when a carrier takes physical possession of the hazardous material for the purpose of transporting it and continues until the package containing the hazardous material is delivered to the destination indicated on a shipping document, package marking, or other medium, or, in the case of a rail car, until the car is delivered to a private track or siding. For a private motor carrier, transportation of a hazardous material in commerce begins when a motor vehicle driver takes possession of a hazardous material for the purpose of transporting it and continues until the driver relinquishes possession of the package containing the hazardous material at its destination and is no longer responsible for performing functions subject to the HMR with respect to that particular package. Transportation of a hazardous material in commerce includes the following:
(1) Movement. Movement of a hazardous material by rail car, aircraft, motor vehicle, or vessel (except as delegated by Department of Homeland Security Delegation No. 0170 at 2(103)).
(2) Loading incidental to movement of a hazardous material. Loading of packaged or containerized hazardous material onto a transport vehicle, aircraft, or vessel for the purpose of transporting it, including blocking and bracing a hazardous materials package in a freight container or transport vehicle, and segregating a hazardous materials package in a freight container or transport vehicle from incompatible cargo, when performed by carrier personnel or in the presence of carrier personnel. For a bulk packaging, loading incidental to movement is filling the packaging with a hazardous material for the purpose of transporting it when performed by carrier personnel or in the presence of carrier personnel (except as delegated by Department of Homeland Security Delegation No. 0170 at 2(103)), including transloading.
(3) Unloading incidental to movement of a hazardous material. Removing a package or containerized hazardous material from a transport vehicle, aircraft, or vessel; or for a bulk packaging, emptying a hazardous material from the bulk packaging after the hazardous material has been delivered to the consignee when performed by carrier personnel or in the presence of carrier personnel or, in the case of a private motor carrier, while the driver of the motor vehicle from which the hazardous material is being unloaded immediately after movement is completed is present during the unloading operation. (Emptying a hazardous material from a bulk packaging while the packaging is on board a vessel is subject to separate regulations as delegated by Department of Homeland Security Delegation No. 0170 at 2(103).) Unloading incidental to movement includes transloading.
(4) Storage incidental to movement of a hazardous material. Storage of a transport vehicle, freight container, or package containing a hazardous material by any person between the time that a carrier takes physical possession of the hazardous material for the purpose of transporting it until the package containing the hazardous material has been delivered to the destination indicated on a shipping document, package marking, or other medium, or, in the case of a private motor carrier, between the time that a motor vehicle driver takes physical possession of the hazardous material for the purpose of transporting it until the driver relinquishes possession of the package at its destination and is no longer responsible for performing functions subject to the HMR with respect to that particular package.

PART 172 – HAZARDOUS MATERIALS TABLE, SPECIAL PROVISIONS, HAZARDOUS MATERIALS COMMUNICATIONS, EMERGENCY RESPONSE INFORMATION, TRAINING REQUIREMENTS, AND SECURITY PLANS
Subpart A – General
§ 172.1 Purpose and scope.
This part lists and classifies those materials which the Department has designated as hazardous materials for purposes of transportation and prescribes the requirements for shipping papers, package marking, labeling, and transport vehicle placarding applicable to the shipment and transportation of those hazardous materials.
§ 172.3 Applicability.
(a) This part applies to –
(1) Each person who offers a hazardous material for transportation, and
(2) Each carrier by air, highway, rail, or water who transports a hazardous material.
(b) When a person, other than one of those provided for in paragraph (a) of this section, performs a packaging labeling or marking function required by this part, that person shall perform the function in accordance with this part.
Subpart B – Table of Hazardous Materials and Special Provisions
§ 172.101 Purpose and use of hazardous materials table.
(a) The Hazardous Materials Table (Table) in this section designates the materials listed therein as hazardous materials for the purpose of transportation of those materials. For each listed material, the Table identifies the hazard class or specifies that the material is forbidden in transportation, and gives the proper shipping name or directs the user to the preferred proper shipping name. In addition, the Table specifies or references requirements in this subchapter pertaining to labeling, packaging, quantity limits aboard aircraft and stowage of hazardous materials aboard vessels.
(b) Column 1: Symbols. Column 1 of the Table contains six symbols (“ + ”, “A”, “D”, “G”, “I” and “W”) as follows:
(1) The plus (+) sign fixes the proper shipping name, hazard class and packing group for that entry without regard to whether the material meets the definition of that class, packing group or any other hazard class definition. When the plus sign is assigned to a proper shipping name in Column (1) of the § 172.101 Table, it means that the material is known to pose a risk to humans. When a plus sign is assigned to mixtures or solutions containing a material where the hazard to humans is significantly different from that of the pure material or where no hazard to humans is posed, the material may be described using an alternative shipping name that represents the hazards posed by the material. An appropriate alternate proper shipping name and hazard class may be authorized by the Associate Administrator.
(2) The letter “A” denotes a material that is subject to the requirements of this subchapter only when offered or intended for transportation by aircraft, unless the material is a hazardous substance or a hazardous waste. A shipping description entry preceded by an “A” may be used to describe a material for other modes of transportation provided all applicable requirements for the entry are met.
(3) The letter “D” identifies proper shipping names which are appropriate for describing materials for domestic transportation but may be inappropriate for international transportation under the provisions of international regulations (e.g., IMO, ICAO). An alternate proper shipping name may be selected when either domestic or international transportation is involved.
(4) The letter “G” identifies proper shipping names for which one or more technical names of the hazardous material must be entered in parentheses, in association with the basic description. (See § 172.203(k).)
(5) The letter “I” identifies proper shipping names which are appropriate for describing materials in international transportation. An alternate proper shipping name may be selected when only domestic transportation is involved.
(6) The letter “W” denotes a material that is subject to the requirements of this subchapter only when offered or intended for transportation by vessel, unless the material is a hazardous substance or a hazardous waste. A shipping description entry preceded by a “W” may be used to describe a material for other modes of transportation provided all applicable requirements for the entry are met.
(c) Column 2: Hazardous materials descriptions and proper shipping names. Column 2 lists the hazardous materials descriptions and proper shipping names of materials designated as hazardous materials. Modification of a proper shipping name may otherwise be required or authorized by this section. Proper shipping names are limited to those shown in Roman type (not italics).
(1) Proper shipping names may be used in the singular or plural and in either capital or lower case letters. Words may be alternatively spelled in the same manner as they appear in the ICAO Technical Instructions or the IMDG Code. For example “aluminum” may be spelled “aluminium” and “sulfur” may be spelled “sulphur”. However, the word “inflammable” may not be used in place of the word “flammable”.
(2) Punctuation marks and words in italics are not part of the proper shipping name, but may be used in addition to the proper shipping name. The word “or” in italics indicates that there is a choice of terms in the sequence that may alternately be used as the proper shipping name or as part of the proper shipping name, as appropriate. For example, for the hazardous materials description “Carbon dioxide, solid or Dry ice” either “Carbon dioxide, solid” or “Dry ice” may be used as the proper shipping name; and for the hazardous materials description “Articles, pressurized pneumatic or hydraulic,” either “Articles, pressurized pneumatic” or “Articles, pressurized hydraulic” may be used as the proper shipping name.
(3) The word “poison” or “poisonous” may be used interchangeably with the word “toxic” when only domestic transportation is involved. The abbreviation “n.o.i.” or “n.o.i.b.n.” may be used interchangeably with “n.o.s.”.
(4) Except for hazardous wastes, when qualifying words are used as part of the proper shipping name, their sequence in the package markings and shipping paper description is optional. However, the entry in the Table reflects the preferred sequence.
(5) When one entry references another entry by use of the word “see”, if both names are in Roman type, either name may be used as the proper shipping name (e.g., Ethyl alcohol, see Ethanol).
(6) When a proper shipping name includes a concentration range as part of the shipping description, the actual concentration, if it is within the range stated, may be used in place of the concentration range. For example, an aqueous solution of hydrogen peroxide containing 30 percent peroxide may be described as “Hydrogen peroxide, aqueous solution with not less than 20 percent but not more than 40 percent hydrogen peroxide” or “Hydrogen peroxide, aqueous solution with 30 percent hydrogen peroxide.” Also, the percent sign (%) may be used in place of the word “percent” when words in italics containing the word “percent” are used in addition to the proper shipping name.
(7) Use of the prefix “mono” is optional in any shipping name, when appropriate. Thus, Iodine monochloride may be used interchangeably with Iodine chloride. In “Glycerol alpha-monochlorohydrin” the term “mono” is considered a prefix to the term “chlorohydrin” and may be deleted.
(8) Use of the word “liquid” or “solid”. The word “liquid” or “solid” may be added to a proper shipping name when a hazardous material specifically listed by name may, due to differing physical states, be a liquid or solid. When the packaging specified in Column 8 is inappropriate for the physical state of the material, the table provided in paragraph (i)(4) of this section should be used to determine the appropriate packaging section.
(9) Hazardous wastes. If the word “waste” is not included in the hazardous material description in Column 2 of the Table, the proper shipping name for a hazardous waste (as defined in § 171.8 of this subchapter), shall include the word “Waste” preceding the proper shipping name of the material. For example: Waste acetone.
(10) Mixtures and solutions. (i) A mixture or solution meeting the definition of one or more hazard class that is not identified specifically by name, comprised of a single predominant hazardous material identified in the Table by technical name and one or more hazardous and/or non-hazardous material, must be described using the proper shipping name of the hazardous material and the qualifying word “mixture” or “solution”, as appropriate, unless –
(A) Except as provided in § 172.101(i)(4) the packaging specified in Column 8 is inappropriate to the physical state of the material;
(B) The shipping description indicates that the proper shipping name applies only to the pure or technically pure hazardous material;
(C) The hazard class, packing group, or subsidiary hazard of the mixture or solution is different from that specified for the entry;
(D) There is a significant change in the measures to be taken in emergencies;
(E) The material is identified by special provision in Column 7 of the § 172.101 Table as a material poisonous by inhalation; however, it no longer meets the definition of poisonous by inhalation or it falls within a different hazard zone than that specified in the special provision; or
(F) The material can be appropriately described by a shipping name that describes its intended application, such as “Coating solution”, “Extracts, flavoring” or “Compound, cleaning liquid.”.
(ii) If one or more of the conditions in paragraphs (c)(10)(i)(A) through (F) of this section is satisfied then the proper shipping name selection process in (c)(12)(ii) must be used.
(iii) A mixture or solution meeting the definition of one or more hazard class that is not identified in the Table specifically by name, comprised of two or more hazardous materials in the same hazard class, must be described using an appropriate shipping description (e.g., “Flammable liquid, n.o.s.”). The name that most appropriately describes the material shall be used; e.g., an alcohol not listed by its technical name in the Table shall be described as “Alcohol, n.o.s.” rather than “Flammable liquid, n.o.s.”. Some mixtures may be more appropriately described according to their application, such as “Coating solution” or “Extracts, flavoring liquid” rather than by an n.o.s. entry. Under the provisions of subparts C and D of this part, the technical names of at least two components most predominately contributing to the hazards of the mixture or solution may be required in association with the proper shipping name.
(11) Except for a material subject to or prohibited by § 173.21, § 173.54, § 173.56(d), § 173.56(e), § 173.224(c) or § 173.225(b) of this subchapter, a material that is considered to be a hazardous waste or a sample of a material for which the hazard class is uncertain and must be determined by testing may be assigned a tentative proper shipping name, hazard class, identification number and packing group, if applicable, based on the shipper’s tentative determination according to:
(i) Defining criteria in this subchapter;
(ii) The hazard precedence prescribed in § 173.2a of this subchapter;
(iii) The shipper’s knowledge of the material;
(iv) In addition to paragraphs (c)(11)(i) through (iii) of this section, for a sample of a material other than a waste, the following must be met:
(A) Except when the word “Sample” already appears in the proper shipping name, the word “Sample” must appear as part of the proper shipping name or in association with the basic description on the shipping paper.
(B) When the proper shipping description for a sample is assigned a “G” in Column (1) of the § 172.101 Table, and the primary constituent(s) for which the tentative classification is based are not known, the provisions requiring a technical name for the constituent(s) do not apply; and
(C) A sample must be transported in a combination packaging that conforms to the requirements of this subchapter that are applicable to the tentative packing group assigned, and may not exceed a net mass of 2.5 kg (5.5 pounds) per package.
For the transportation of samples of self-reactive materials, organic peroxides, explosives or lighters, see § 173.224(c)(3), § 173.225(c)(2), § 173.56(d) or § 173.308(b)(2) of this subchapter, respectively.
(12) Except when the proper shipping name in the Table is preceded by a plus (+) –
(i) If it is specifically determined that a material meets the definition of a hazard class, packing group or hazard zone, other than the class, packing group or hazard zone shown in association with the proper shipping name, or does not meet the defining criteria for a subsidiary hazard shown in Column 6 of the Table, the material shall be described by an appropriate proper shipping name listed in association with the correct hazard class, packing group, hazard zone, or subsidiary hazard for the material.
(ii) Generic or n.o.s. descriptions. If an appropriate technical name is not shown in the Table, selection of a proper shipping name shall be made from the generic or n.o.s. descriptions corresponding to the specific hazard class, packing group, hazard zone, or subsidiary hazard, if any, for the material. The name that most appropriately describes the material shall be used; e.g., an alcohol not listed by its technical name in the Table shall be described as “Alcohol, n.o.s.” rather than “Flammable liquid, n.o.s.”. Some mixtures may be more appropriately described according to their application, such as “Coating solution” or “Extracts, flavoring, liquid”, rather than by an n.o.s. entry, such as “Flammable liquid, n.o.s.” It should be noted, however, that an n.o.s. description as a proper shipping name may not provide sufficient information for shipping papers and package markings. Under the provisions of subparts C and D of this part, the technical name of one or more constituents which makes the product a hazardous material may be required in association with the proper shipping name.
(iii) Multiple hazard materials. If a material meets the definition of more than one hazard class, and is not identified in the Table specifically by name (e.g., acetyl chloride), the hazard class of the material shall be determined by using the precedence specified in § 173.2a of this subchapter, and an appropriate shipping description (e.g., “Flammable liquid, corrosive n.o.s.”) shall be selected as described in paragraph (c)(12)(ii) of this section.
(iv) If it is specifically determined that a material is not a forbidden material and does not meet the definition of any hazard class, the material is not a hazardous material.
(13) Self-reactive materials and organic peroxides. A generic proper shipping name for a self-reactive material or an organic peroxide, as listed in Column 2 of the Table, must be selected based on the material’s technical name and concentration, in accordance with the provisions of § 173.224 or § 173.225 of this subchapter, respectively.
(14) A proper shipping name that describes all isomers of a material may be used to identify any isomer of that material if the isomer meets criteria for the same hazard class or division, subsidiary risk(s) and packing group, unless the isomer is specifically identified in the Table.
(15) Unless a hydrate is specifically listed in the Table, a proper shipping name for the equivalent anhydrous substance may be used, if the hydrate meets the same hazard class or division, subsidiary risk(s) and packing group.
(16) Unless it is already included in the proper shipping name in the § 172.101 Table, the qualifying words “liquid” or “solid” may be added in association with the proper shipping name when a hazardous material specifically listed by name in the § 172.101 Table may, due to the differing physical states of the various isomers of the material, be either a liquid or a solid (for example “Dinitrotoluenes, liquid” and “Dinitrotoluenes, solid”). Use of the words “liquid” or “solid” is subject to the limitations specified for the use of the words “mixture” or “solution” in paragraph (c)(10) of this section. The qualifying word “molten” may be added in association with the proper shipping name when a hazardous material, which is a solid in accordance with the definition in § 171.8 of this subchapter, is offered for transportation in the molten state (for example, “Alkylphenols, solid, n.o.s., molten”).
(17) Unless it is already included in the proper shipping name in the § 172.101 Table, the qualifying word “stabilized” may be added in association with the proper shipping name, as appropriate, where without stabilization the substance would be forbidden for transportation according to § 173.21(f) of this subchapter.
(d) Column 3: Hazard class or Division. Column 3 contains a designation of the hazard class or division corresponding to each proper shipping name, or the word “Forbidden”.
(1) A material for which the entry in this column is “Forbidden” may not be offered for transportation or transported. This prohibition does not apply if the material is diluted, stabilized or incorporated in a device and it is classed in accordance with the definitions of hazardous materials contained in part 173 of this subchapter.
(2) When a reevaluation of test data or new data indicates a need to modify the “Forbidden” designation or the hazard class or packing group specified for a material specifically identified in the Table, this data should be submitted to the Associate Administrator.
(3) A basic description of each hazard class and the section reference for class definitions appear in § 173.2 of this subchapter.
(4) Each reference to a Class 3 material is modified to read “Combustible liquid” when that material is reclassified in accordance with § 173.150(e) or (f) of this subchapter or has a flash point above 60 °C (140 °F) but below 93 °C (200 °F).
(e) Column 4: Identification number. Column 4 lists the identification number assigned to each proper shipping name. Those preceded by the letters “UN” are associated with proper shipping names considered appropriate for international transportation as well as domestic transportation. Those preceded by the letters “NA” are associated with proper shipping names not recognized for transportation outside of the United States. Identification numbers in the “NA9000” series are associated with proper shipping names not appropriately covered by international hazardous materials (dangerous goods) transportation standards, or not appropriately addressed by international transportation standards for emergency response information purposes, except for transportation in the United States. Those preceded by the letters “ID” are associated with proper shipping names recognized by the ICAO Technical Instructions (see § 171.7 of this subchapter for availability).
(f) Column 5: Packing group. Column 5 specifies one or more packing groups assigned to a material corresponding to the proper shipping name and hazard class for that material. Class 2, Class 7, Division 6.2 (other than regulated medical wastes), and ORM-D materials, do not have packing groups. Articles in other than Class 1 are not assigned to packing groups. For packing purposes, any requirement for a specific packaging performance level is set out in the applicable packing authorizations of part 173. Packing Groups I, II and III indicate the degree of danger presented by the material is great, medium or minor, respectively. If more than one packing group is indicated for an entry, the packing group for the hazardous material is determined using the criteria for assignment of packing groups specified in subpart D of part 173. When a reevaluation of test data or new data indicates a need to modify the specified packing group(s), the data should be submitted to the Associate Administrator. Each reference in this column to a material which is a hazardous waste or a hazardous substance, and whose proper shipping name is preceded in Column 1 of the Table by the letter “A” or “W”, is modified to read “III” on those occasions when the material is offered for transportation or transported by a mode in which its transportation is not otherwise subject to requirements of this subchapter.
(g) Column 6: Labels. Column 6 specifies codes which represent the hazard warning labels required for a package filled with a material conforming to the associated hazard class and proper shipping name, unless the package is otherwise excepted from labeling by a provision in subpart E of this part, or part 173 of this subchapter. The first code is indicative of the primary hazard of the material. Additional label codes are indicative of subsidiary hazards. Provisions in § 172.402 may require that a label other than that specified in Column 6 be affixed to the package in addition to that specified in Column 6. No label is required for a material classed as a combustible liquid or for a Class 3 material that is reclassed as a combustible liquid. For “Empty” label requirements, see § 173.428 of this subchapter. The codes contained in Column 6 are defined according to the following table:
Label Substitution Table
| Label code | Label name |
|---|---|
| 1 | Explosive |
| 1.1 1 | Explosive 1.1 1 |
| 1.2 1 | Explosive 1.2 1 |
| 1.3 1 | Explosive 1.3 1 |
| 1.4 1 | Explosive 1.4 1 |
| 1.5 1 | Explosive 1.5 1 |
| 1.6 1 | Explosive 1.6 1 |
| 2.1 | Flammable Gas |
| 2.2 | Non-Flammable Gas |
| 2.3 | Poison Gas |
| 3 | Flammable Liquid |
| 4.1 | Flammable Solid |
| 4.2 | Spontaneously Combustible |
| 4.3 | Dangerous When Wet |
| 5.1 | Oxidizer |
| 5.2 | Organic Peroxide |
| 6.1 (inhalation hazard, Zone A or B) | Poison Inhalation Hazard |
| 6.1 (other than inhalation hazard, Zone A or B) 2 | Poison |
| 6.2 | Infectious substance |
| 7 | Radioactive |
| 8 | Corrosive |
| 9 | Class 9 |
1 Refers to the appropriate compatibility group letter.
2 The packing group for a material is indicated in column 5 of the table.
(h) Column 7: Special provisions. Column 7 specifies codes for special provisions applicable to hazardous materials. When Column 7 refers to a special provision for a hazardous material, the meaning and requirements of that special provision are as set forth in § 172.102 of this subpart.
(i) Column 8: Packaging authorizations. Columns 8A, 8B and 8C specify the applicable sections for exceptions, non-bulk packaging requirements and bulk packaging requirements, respectively, in part 173 of this subchapter. Columns 8A, 8B and 8C are completed in a manner which indicates that “§ 173.” precedes the designated numerical entry. For example, the entry “202” in Column 8B associated with the proper shipping name “Gasoline” indicates that for this material conformance to non-bulk packaging requirements prescribed in § 173.202 of this subchapter is required. When packaging requirements are specified, they are in addition to the standard requirements for all packagings prescribed in § 173.24 of this subchapter and any other applicable requirements in subparts A and B of part 173 of this subchapter.
(1) Exceptions. Column 8A contains exceptions from some of the requirements of this subchapter. The referenced exceptions are in addition to those specified in subpart A of part 173 and elsewhere in this subchapter. A “None” in this column means no packaging exceptions are authorized, except as may be provided by special provisions in Column 7.
(2) Non-bulk packaging. Column 8B references the section in part 173 of this subchapter which prescribes packaging requirements for non-bulk packagings. A “None” in this column means non-bulk packagings are not authorized, except as may be provided by special provisions in Column 7. Each reference in this column to a material which is a hazardous waste or a hazardous substance, and whose proper shipping name is preceded in Column 1 of the Table by the letter “A” or “W”, is modified to include “§ 173.203” or “§ 173.213”, as appropriate for liquids and solids, respectively, on those occasions when the material is offered for transportation or transported by a mode in which its transportation is not otherwise subject to the requirements of this subchapter.
(3) Bulk packaging. Column (8C) specifies the section in part 173 of this subchapter that prescribes packaging requirements for bulk packagings, subject to the limitations, requirements, and additional authorizations of Columns (7) and (8B). A “None” in Column (8C) means bulk packagings are not authorized, except as may be provided by special provisions in Column (7) and in packaging authorizations Column (8B). Additional authorizations and limitations for use of UN portable tanks are set forth in Column 7. For each reference in this column to a material that is a hazardous waste or a hazardous substance, and whose proper shipping name is preceded in Column 1 of the Table by the letter “A” or “W” and that is offered for transportation or transported by a mode in which its transportation is not otherwise subject to the requirements of this subchapter:
(4) For a hazardous material which is specifically named in the Table and whose packaging sections specify packagings not applicable to the form of the material (e.g., packaging specified is for solid material and the material is being offered for transportation in a liquid form) the following table should be used to determine the appropriate packaging section:
| Packaging section reference for solid materials | Corresponding packaging section for liquid materials |
|---|---|
| § 173.187 | § 173.181 |
| § 173.211 | § 173.201 |
| § 173.212 | § 173.202 |
| § 173.213 | § 173.203 |
| § 173.240 | § 173.241 |
| § 173.242 | § 173.243 |
(5) Cylinders. For cylinders, both non-bulk and bulk packaging authorizations are set forth in Column (8B). Notwithstanding a designation of “None” in Column (8C), a bulk cylinder may be used when specified through the section reference in Column (8B).
(j) Column 9: Quantity limitations. Columns 9A and 9B specify the maximum quantities that may be offered for transportation in one package by passenger-carrying aircraft or passenger-carrying rail car (Column 9A) or by cargo aircraft only (Column 9B), subject to the following:
(1) “Forbidden” means the material may not be offered for transportation or transported in the applicable mode of transport.
(2) The quantity limitation is “net” except where otherwise specified, such as for “Consumer commodity” which specifies “30 kg gross.”
(3) When articles or devices are specifically listed by name, the net quantity limitation applies to the entire article or device (less packaging and packaging materials) rather than only to its hazardous components.
(4) A package offered or intended for transportation by aircraft and which is filled with a material forbidden on passenger-carrying aircraft but permitted on cargo aircraft only, or which exceeds the maximum net quantity authorized on passenger-carrying aircraft, shall be labelled with the CARGO AIRCRAFT ONLY label specified in § 172.448 of this part.
(5) The total net quantity of hazardous material for an outer non-bulk packaging that contains more than one hazardous material may not exceed the lowest permitted maximum net quantity per package as shown in Column 9A or 9B, as appropriate. If one material is a liquid and one is a solid, the maximum net quantity must be calculated in kilograms. See § 173.24a(c)(1)(iv).
(k) Column 10: Vessel stowage requirements. Column 10A [Vessel stowage] specifies the authorized stowage locations on board cargo and passenger vessels. Column 10B [Other provisions] specifies codes for stowage and handling requirements for specific hazardous materials. Hazardous materials offered for transportation as limited quantities are allocated stowage category A and are not subject to the stowage codes assigned by column 10B. The meaning of each code in Column 10B is set forth in § 176.84 of this subchapter. Section 176.63 of this subchapter sets forth the physical requirements for each of the authorized locations listed in Column 10A. (For bulk transportation by vessel, see 46 CFR parts 30 to 40, 70, 98, 148, 151, 153 and 154.) The authorized stowage locations specified in Column 10A are defined as follows:
(1) Stowage category “A” means the material may be stowed “on deck” or “under deck” on a cargo vessel or on a passenger vessel.
(2) Stowage category “B” means –
(i) The material may be stowed “on deck” or “under deck” on a cargo vessel and on a passenger vessel carrying a number of passengers limited to not more than the larger of 25 passengers, or one passenger per each 3 m of overall vessel length; and
(ii) “On deck only” on passenger vessels in which the number of passengers specified in paragraph (k)(2)(i) of this section is exceeded.
(3) Stowage category “C” means the material must be stowed “on deck only” on a cargo vessel or on a passenger vessel.
(4) Stowage category “D” means the material must be stowed “on deck only” on a cargo vessel or on a passenger vessel carrying a number of passengers limited to not more than the larger of 25 passengers or one passenger per each 3 m of overall vessel length, but the material is prohibited on a passenger vessel in which the limiting number of passengers is exceeded.
(5) Stowage category “E” means the material may be stowed “on deck” or “under deck” on a cargo vessel or on a passenger vessel carrying a number of passengers limited to not more than the larger of 25 passengers, or one passenger per each 3 m of overall vessel length, but is prohibited from carriage on a passenger vessel in which the limiting number of passengers is exceeded.
(6) Stowage category “01” means the material may be stowed “on deck” in closed cargo transport units or “under deck” on a cargo vessel (up to 12 passengers) or on a passenger vessel.
(7) Stowage category “02” means the material may be stowed “on deck” in closed cargo transport units or “under deck” on a cargo vessel (up to 12 passengers) or “on deck” in closed cargo transport units or “under deck” in closed cargo transport units on a passenger vessel.
(8) Stowage category “03” means the material may be stowed “on deck” in closed cargo transport units or “under deck” on a cargo vessel (up to 12 passengers) but the material is prohibited on a passenger vessel.
(9) Stowage category “04” means the material may be stowed “on deck” in closed cargo transport units or “under deck” in closed cargo transports on a cargo vessel (up to 12 passengers) but the material is prohibited on a passenger vessel.
(10) Stowage category “05” means the material may be stowed “on deck” in closed cargo transport units on a cargo vessel (up to 12 passengers) but the material is prohibited on a passenger vessel.
(l) Changes to the Table. (1) Unless specifically stated otherwise in a rule document published in the
(i) Such a change does not apply to the shipment of any package filled prior to the effective date of the amendment; and
(ii) Stocks of preprinted shipping papers and package markings may be continued in use, in the manner previously authorized, until depleted or for a one-year period, subsequent to the effective date of the amendment, whichever is less.
(2) Except as otherwise provided in this section, any alteration of a shipping description or associated entry which is listed in the § 172.101 Table must receive prior written approval from the Associate Administrator.
(3) The proper shipping name of a hazardous material changed in the May 6, 1997 final rule, in effect on October 1, 1997, only by the addition or omission of the word “compressed,” “inhibited,” “liquefied” or “solution” may continue to be used to comply with package marking requirements, until January 1, 2003.

1. This appendix lists materials and their corresponding reportable quantities (RQ’s) that are listed or designated as “hazardous substances” under section 101(14) of the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C. 9601(14) (CERCLA; 42 U.S.C. 9601 et seq). This listing fulfills the requirement of CERCLA, 42 U.S.C. 9656(a), that all “hazardous substances,” as defined in 42 U.S.C. 9601(14), be listed and regulated as hazardous materials under 49 U.S.C. 5101-5127. That definition includes substances listed under sections 311(b)(2)(A) and 307(a) of the Federal Water Pollution Control Act, 33 U.S.C. 1321(b)(2)(A) and 1317(a), section 3001 of the Solid Waste Disposal Act, 42 U.S.C. 6921, and section 112 of the Clean Air Act, 42 U.S.C. 7412. In addition, this list contains materials that the Administrator of the Environmental Protection Agency has determined to be hazardous substances in accordance with section 102 of CERCLA, 42 U.S.C. 9602. It should be noted that 42 U.S.C. 9656(b) provides that common and contract carriers may be held liable under laws other than CERCLA for the release of a hazardous substance as defined in that Act, during transportation that commenced before the effective date of the listing and regulating of that substance as a hazardous material under 49 U.S.C. 5101-5127.
2. This appendix is divided into two TABLES which are entitled “TABLE 1 – HAZARDOUS SUBSTANCES OTHER THAN RADIONUCLIDES” and “TABLE 2 – RADIONUCLIDES.” A material listed in this appendix is regulated as a hazardous material and a hazardous substance under this subchapter if it meets the definition of a hazardous substance in § 171.8 of this subchapter.
3. The procedure for selecting a proper shipping name for a hazardous substance is set forth in § 172.101(c).
4. Column 1 of TABLE 1, entitled “Hazardous substance”, contains the names of those elements and compounds that are hazardous substances. Following the listing of elements and compounds is a listing of waste streams. These waste streams appear on the list in numerical sequence and are referenced by the appropriate “D”, “F”, or “K” numbers. Column 2 of TABLE 1, entitled “Reportable quantity (RQ)”, contains the reportable quantity (RQ), in pounds and kilograms, for each hazardous substance listed in Column 1 of TABLE 1.
5. A series of notes is used throughout TABLE 1 and TABLE 2 to provide additional information concerning certain hazardous substances. These notes are explained at the end of each TABLE.
6. TABLE 2 lists radionuclides that are hazardous substances and their corresponding RQ’s. The RQ’s in table 2 for radionuclides are expressed in units of curies and terabecquerels, whereas those in table 1 are expressed in units of pounds and kilograms. If a material is listed in both table 1 and table 2, the lower RQ shall apply. Radionuclides are listed in alphabetical order. The RQ’s for radionuclides are given in the radiological unit of measure of curie, abbreviated “Ci”, followed, in parentheses, by an equivalent unit measured in terabecquerels, abbreviated “TBq”.
7. For mixtures of radionuclides, the following requirements shall be used in determining if a package contains an RQ of a hazardous substance: (i) if the identity and quantity (in curies or terabecquerels) of each radionuclide in a mixture or solution is known, the ratio between the quantity per package (in curies or terabecquerels) and the RQ for the radionuclide must be determined for each radionuclide. A package contains an RQ of a hazardous substance when the sum of the ratios for the radionuclides in the mixture or solution is equal to or greater than one; (ii) if the identity of each radionuclide in a mixture or solution is known but the quantity per package (in curies or terabecquerels) of one or more of the radionuclides is unknown, an RQ of a hazardous substance is present in a package when the total quantity (in curies or terabecquerels) of the mixture or solution is equal to or greater than the lowest RQ of any individual radionuclide in the mixture or solution; and (iii) if the identity of one or more radionuclides in a mixture or solution is unknown (or if the identity of a radionuclide by itself is unknown), an RQ of a hazardous substance is present when the total quantity (in curies or terabecquerels) in a package is equal to or greater than either one curie or the lowest RQ of any known individual radionuclide in the mixture or solution, whichever is lower.

$ The RQs for all radionuclides apply to chemical compounds containing the radionuclides and elemental forms regardless of the diameter of pieces of solid material.
† The RQ of one curie applies to all radionuclides not otherwise listed. Whenever the RQs in TABLE 1 – HAZARDOUS SUBSTANCES OTHER THAN RADIONUCLIDES and this table conflict, the lowest RQ shall apply. For example, uranyl acetate and uranyl nitrate have RQs shown in TABLE 1 of 100 pounds, equivalent to about one-tenth the RQ level for uranium-238 in this table.
** The method to determine the RQs for mixtures or solutions of radionuclides can be found in paragraph 7 of the note preceding TABLE 1 of this appendix. RQs for the following four common radionuclide mixtures are provided: radium-226 in secular equilibrium with its daughters (0.053 curie); natural uranium (0.1 curie); natural uranium in secular equilibrium with its daughters (0.052 curie); and natural thorium in secular equilibrium with its daughters (0.011 curie).
*** Indicates that the name was added by PHMSA because it appears in the list of radionuclides in 49 CFR 173.435. The reportable quantity (RQ), if not specifically listed elsewhere in this appendix, shall be determined in accordance with the procedures in paragraph 7 of this appendix.
1. See § 171.4 of this subchapter for applicability to marine pollutants. This appendix lists potential marine pollutants as defined in § 171.8 of this subchapter.
2. Marine pollutants listed in this appendix are not necessarily listed by name in the § 172.101 Table. If a marine pollutant not listed by name or by synonym in the § 172.101 Table meets the definition of any hazard Class 1 through 8, then you must determine the class and division of the material in accordance with § 173.2a of this subchapter. You must also select the most appropriate hazardous material description and proper shipping name. If a marine pollutant not listed by name or by synonym in the § 172.101 Table does not meet the definition of any Class 1 through 8, then you must offer it for transportation under the most appropriate of the following two Class 9 entries: “Environmentally hazardous substances, liquid, n.o.s.,” UN3082, or “Environmentally hazardous substances, solid, n.o.s.” UN3077.
3. This appendix contains two columns. The first column, entitled “S.M.P.” (for severe marine pollutants), identifies whether a material is a severe marine pollutant. If the letters “PP” appear in this column for a material, the material is a severe marine pollutant, otherwise it is not. The second column, entitled “Marine Pollutant” , lists the marine pollutants.
4. If a material is not listed in this appendix and meets the criteria for a marine pollutant as provided in Chapter 2.9 of the IMDG Code, (incorporated by reference; see § 171.7 of this subchapter), the material may be transported as a marine pollutant in accordance with the applicable requirements of this subchapter.
5. If a material or a solution meeting the definition of a marine pollutant in § 171.8 of this subchapter does not meet the criteria for a marine pollutant as provided in section 2.9.3.3 and 2.9.3.4 of the IMDG Code, (incorporated by reference; see § 171.7 of this subchapter), it may be excepted from the requirements of this subchapter as a marine pollutant if that exception is approved by the Associate Administrator.

§ 172.102 Special provisions.
(a) General. When column 7 of the § 172.101 table refers to a special provision for a hazardous material, the meaning and requirements of that provision are as set forth in this section. When a special provision specifies packaging or packaging requirements –
(1) The special provision is in addition to the standard requirements for all packagings prescribed in § 173.24 of this subchapter and any other applicable packaging requirements in subparts A and B of part 173 of this subchapter; and
(2) To the extent a special provision imposes limitations or additional requirements on the packaging provisions set forth in column 8 of the § 172.101 table, packagings must conform to the requirements of the special provision.
(b) Description of codes for special provisions. Special provisions contain packaging provisions, prohibitions, exceptions from requirements for particular quantities or forms of materials and requirements or prohibitions applicable to specific modes of transportation, as follows:
(1) A code consisting only of numbers (for example, “11”) is multi-modal in application and may apply to bulk and non-bulk packagings.
(2) A code containing the letter “A” refers to a special provision which applies only to transportation by aircraft.
(3) A code containing the letter “B” refers to a special provision that applies only to bulk packaging requirements. Unless otherwise provided in this subchapter, these special provisions do not apply to UN, IM Specification portable tanks or IBCs.
(4) A code containing the letters “IB” or “IP” refers to a special provision that applies only to transportation in IBCs.
(5) A code containing the letter “N” refers to a special provision which applies only to non-bulk packaging requirements.
(6) A code containing the letter “R” refers to a special provision which applies only to transportation by rail.
(7) A code containing the letter “T” refers to a special provision which applies only to transportation in UN or IM Specification portable tanks.
(8) A code containing the letters “TP” refers to a portable tank special provision for UN or IM Specification portable tanks that is in addition to those provided by the portable tank instructions or the requirements in part 178 of this subchapter.
(9) A code containing the letter “W” refers to a special provision that applies only to transportation by water.
(c) Tables of special provisions. The following tables list, and set forth the requirements of, the special provisions referred to in column 7 of the § 172.101 table.
(1) Numeric provisions. These provisions are multi-modal and apply to bulk and non-bulk packagings:
(122 °F). If chemical stabilization becomes ineffective at lower temperatures within the anticipated duration of transport, temperature control is required and is forbidden by aircraft. In making this determination factors to be taken into consideration include, but are not limited to, the capacity and geometry of the packaging and the effect of any insulation present, the temperature of the material when offered for transport, the duration of the journey, and the ambient temperature conditions typically encountered in the journey (considering also the season of year), the effectiveness and other properties of the stabilizer employed, applicable operational controls imposed by regulation (e.g., requirements to protect from sources of heat, including other cargo carried at a temperature above ambient) and any other relevant factors. The provisions of this special provision will be effective until January 2, 2023, unless we terminate them earlier or extend them beyond that date by notice of a final rule in the
(2) “A” codes. These provisions apply only to transportation by aircraft:
(3) “B” codes. These provisions apply only to bulk packagings. Except as otherwise provided in this subchapter, these special provisions do not apply to UN portable tanks or IBCs:
Table I – Maximum Ambient Temperature – Gasoline
| ASTM D439 volatility class | Maximum lading and ambient temperature (see note 1) |
|---|---|
| A | 131 °F |
| (RVP ≤ 9.0 psia) | |
| B | 124 °F |
| (RVP ≤ 10.0 psia) | |
| C | 116 °F |
| (RVP ≤ 11.5 psia) | |
| D | 107 °F |
| (RVP ≤ 13.5 psia) | |
| E | 100 °F |
| (RVP ≤ 15.0 psia) |
(4) IB Codes and IP Codes. These provisions apply only to transportation in IBCs and Large Packagings. Table 1 authorizes IBCs for specific proper shipping names through the use of IB Codes assigned in the § 172.101 table of this subchapter. Table 2 defines IP Codes on the use of IBCs that are assigned to specific commodities in the § 172.101 Table of this subchapter. Table 3 authorizes Large Packagings for specific proper shipping names through the use of IB Codes assigned in the § 172.101 table of this subchapter. Large Packagings are authorized for the Packing Group III entries of specific proper shipping names when either special provision IB3 or IB8 is assigned to that entry in the § 172.101 Table. When no IB code is assigned in the § 172.101 Table for a specific proper shipping name, or in § 173.185 or § 173.225(e) Organic Peroxide Table for Type F organic peroxides, use of an IBC or Large Packaging for the material may be authorized when approved by the Associate Administrator. The letter “Z” shown in the marking code for composite IBCs must be replaced with a capital code letter designation found in § 178.702(a)(2) of this subchapter to specify the material used for the other packaging. Tables 1, 2, and 3 follow:
Table 1 – IB Codes (IBC Codes)

| IB9 | IBCs are only authorized if approved by the Associate Administrator. |
Table 2 – IP Codes
| IP code | |
|---|---|
| IP1 | IBCs must be packed in closed freight containers or a closed transport vehicle. |
| IP2 | When IBCs other than metal or rigid plastics IBCs are used, they must be offered for transportation in a closed freight container or a closed transport vehicle. |
| IP3 | Flexible IBCs must be sift-proof and water-resistant or must be fitted with a sift-proof and water-resistant liner. |
| IP4 | Flexible, fiberboard or wooden IBCs must be sift-proof and water-resistant or be fitted with a sift-proof and water-resistant liner. |
| IP5 | IBCs must have a device to allow venting. The inlet to the venting device must be located in the vapor space of the IBC under maximum filling conditions. |
| IP6 | Non-specification bulk bins are authorized. |
| IP7 | For UN identification numbers 1327, 1363, 1364, 1365, 1386, 1841, 2211, 2217, 2793 and 3314, IBCs are not required to meet the IBC performance tests specified in part 178, subpart N, of this subchapter. |
| IP8 | Ammonia solutions may be transported in rigid or composite plastic IBCs (31H1, 31H2 and 31HZ1) that have successfully passed, without leakage or permanent deformation, the hydrostatic test specified in § 178.814 of this subchapter at a test pressure that is not less than 1.5 times the vapor pressure of the contents at 55 °C (131 °F). |
| IP13 | Transportation by vessel in IBCs is prohibited. |
| IP14 | Air must be eliminated from the vapor space by nitrogen or other means. |
| IP15 | For UN2031 with more than 55% nitric acid, rigid plastic IBCs and composite IBCs with a rigid plastic inner receptacle are authorized for two years from the date of IBC manufacture. |
| IP16 | IBCs of type 31A and 31N are only authorized if approved by the Associate Administrator. |
| IP19 | For UN identification numbers 3531, 3532, 3533, and 3534, IBCs must be designed and constructed to permit the release of gas or vapor to prevent a build-up of pressure that could rupture the IBCs in the event of loss of stabilization. |
| IP20 | Dry sodium cyanide or potassium cyanide is also permitted in siftproof, water-resistant, fiberboard IBCs when transported in closed freight containers or transport vehicles. |
| IP21 | When transported by vessel, flexible, fiberboard or wooden IBCs must be sift-proof and water-resistant or be fitted with a sift-proof and water-resistant liner. |

(4) A high-hazard flammable train (HHFT) as defined in § 171.8 of this subchapter; or
(5) A quantity of UN1972 (Methane, refrigerated liquid or Natural gas, refrigerated liquid) when transported in a rail tank car.
(b) Not later than 90 days after the end of each calendar year, a rail carrier must compile commodity data for the previous calendar year for the materials listed in paragraph (a) of this section. The following stipulations apply to data collected:
(1) Commodity data must be collected by route, a line segment or series of line segments as aggregated by the rail carrier. Within the rail carrier selected route, the commodity data must identify the geographic location of the route and the total number of shipments by UN identification number for the materials specified in paragraph (a) of this section.
(i) A rail carrier subject to additional planning requirements of this section based on paragraph (a)(5) of this section that has yet to transport UN 1972, must factor in planned shipments of UN 1972 to the commodity data for use in the paragraph (c) route analysis prior to initial transport of the material.
(ii) [Reserved]
(2) A carrier may compile commodity data, by UN number, for all Class 7 materials transported (instead of only highway route controlled quantities of Class 7 materials) and for all Division 6.1 materials transported (instead of only Division 6.1 poison inhalation hazard materials).
(c) Rail transportation route analysis. For each calendar year, a rail carrier must analyze the safety and security risks for the transportation route(s), identified in the commodity data collected as required by paragraph (b) of this section. The route analysis must be in writing and include the factors contained in appendix D to this part, as applicable.
(1) The safety and security risks present must be analyzed for the route and railroad facilities along the route. For purposes of this section, railroad facilities are railroad property including, but not limited to, classification and switching yards, storage facilities, and non-private sidings. This term does not include an offeror’s facility, private track, private siding, or consignee’s facility.
(2) In performing the analysis required by this paragraph, the rail carrier must seek relevant information from state, local, and tribal officials, as appropriate, regarding security risks to high-consequence targets along or in proximity to the route(s) utilized. If a rail carrier is unable to acquire relevant information from state, local, or tribal officials, then it must document that in its analysis. For purposes of this section, a high-consequence target means a property, natural resource, location, area, or other target designated by the Secretary of Homeland Security that is a viable terrorist target of national significance, the attack of which by railroad could result in catastrophic loss of life, significant damage to national security or defense capabilities, or national economic harm.
(d) Alternative route analysis. (1) For each calendar year, a rail carrier must identify practicable alternative routes over which it has authority to operate, if an alternative exists, as an alternative route for each of the transportation routes analyzed in accordance with paragraph (c) of this section. The carrier must perform a safety and security risk assessment of the alternative routes for comparison to the route analysis prescribed in paragraph (c) of this section. The alternative route analysis must be in writing and include the criteria in appendix D of this part. When determining practicable alternative routes, the rail carrier must consider the use of interchange agreements with other rail carriers. The written alternative route analysis must also consider:
(i) Safety and security risks presented by use of the alternative route(s);
(ii) Comparison of the safety and security risks of the alternative(s) to the primary rail transportation route, including the risk of a catastrophic release from a shipment traveling along each route;
(iii) Any remediation or mitigation measures implemented on the primary or alternative route(s); and
(iv) Potential economic effects of using the alternative route(s), including but not limited to the economics of the commodity, route, and customer relationship.
(2) In performing the analysis required by this paragraph, the rail carrier should seek relevant information from state, local, and tribal officials, as appropriate, regarding security risks to high-consequence targets along or in proximity to the alternative routes. If a rail carrier determines that it is not appropriate to seek such relevant information, then it must explain its reasoning for that determination in its analysis.
(e) Route Selection. A carrier must use the analysis performed as required by paragraphs (c) and (d) of this section to select the route to be used in moving the materials covered by paragraph (a) of this section. The carrier must consider any remediation measures implemented on a route. Using this process, the carrier must at least annually review and select the practicable route posing the least overall safety and security risk. The rail carrier must retain in writing all route review and selection decision documentation and restrict the distribution, disclosure, and availability of information contained in the route analysis to covered persons with a need-to-know, as described in parts 15 and 1520 of this title. This documentation should include, but is not limited to, comparative analyses, charts, graphics or rail system maps.
(f) Completion of route analysis. (1) The rail transportation route analysis, alternative route analysis, and route selection process required under paragraphs (c), (d), and (e) of this section must be completed no later than the end of the calendar year following the year to which the analyses apply.
(2) The initial analysis and route selection determinations required under paragraphs (c), (d), and (e) of this section must include a comprehensive review of the entire system. Subsequent analyses and route selection determinations required under paragraphs (c), (d), and (e) of this section must include a comprehensive, system-wide review of all operational changes, infrastructure modifications, traffic adjustments, changes in the nature of high-consequence targets located along, or in proximity to, the route, and any other changes affecting the safety or security of the movements of the materials specified in paragraph (a) of this section that were implemented during the calendar year.
(3) A rail carrier need not perform a rail transportation route analysis, alternative route analysis, or route selection process for any hazardous material other than the materials specified in paragraph (a) of this section.
(g) Rail carrier point of contact on routing issues. Each rail carrier must identify a point of contact (including the name, title, phone number and e-mail address) on routing issues involving the movement of materials covered by this section in its security plan and provide this information to:
(1) State and/or regional Fusion Centers that have been established to coordinate with state, local and tribal officials on security issues and which are located within the area encompassed by the rail carrier’s rail system; and
(2) State, local, and tribal officials in jurisdictions that may be affected by a rail carrier’s routing decisions and who directly contact the railroad to discuss routing decisions.
(h) Storage, delays in transit, and notification. With respect to the materials specified in paragraph (a) of this section, each rail carrier must ensure the safety and security plan it develops and implements under this subpart includes all of the following:
(1) A procedure under which the rail carrier must consult with offerors and consignees in order to develop measures for minimizing, to the extent practicable, the duration of any storage of the material incidental to movement (see § 171.8 of this subchapter).
(2) Measures to prevent unauthorized access to the materials during storage or delays in transit.
(3) Measures to mitigate risk to population centers associated with in-transit storage.
(4) Measures to be taken in the event of an escalating threat level for materials stored in transit.
(5) Procedures for notifying the consignee in the event of a significant delay during transportation; such notification must be completed within 48 hours after the carrier has identified the delay and must include a revised delivery schedule. A significant delay is one that compromises the safety or security of the hazardous material or delays the shipment beyond its normal expected or planned shipping time. Notification should be made by a method acceptable to both the rail carrier and consignee.
(i) Recordkeeping. (1) Each rail carrier must maintain a copy of the information specified in paragraphs (b), (c), (d), (e), and (f) of this section (or an electronic image thereof) that is accessible at, or through, its principal place of business and must make the record available upon request, at a reasonable time and location, to an authorized official of the Department of Transportation or the Department of Homeland Security. Records must be retained for a minimum of two years.
(2) Each rail carrier must restrict the distribution, disclosure, and availability of information collected or developed in accordance with paragraphs (c), (d), (e), and (f) of this section to covered persons with a need-to-know, as described in parts 15 and 1520 of this title.
(j) Compliance and enforcement. If the carrier’s route selection documentation and underlying analyses are found to be deficient, the carrier may be required to revise the analyses or make changes in route selection. If DOT finds that a chosen route is not the safest and most secure practicable route available, the FRA Associate Administrator for Safety, in consultation with TSA, may require the use of an alternative route. Prior to making such a determination, FRA and TSA will consult with the Surface Transportation Board (STB) regarding whether the contemplated alternative route(s) would be economically practicable.
§ 172.822 Limitation on actions by states, local governments, and Indian tribes.
A law, order, or other directive of a state, political subdivision of a state, or an Indian tribe that designates, limits, or prohibits the use of a rail line (other than a rail line owned by a state, political subdivision of a state, or an Indian tribe) for the transportation of hazardous materials, including, but not limited to, the materials specified in § 172.820(a), is preempted. 49 U.S.C. 5125, 20106.
Appendix A to Part 172 – Office of Hazardous Materials Transportation Color Tolerance Charts and Tables
The following are Munsell notations and Commission Internationale de L’Eclairage (CIE) coordinates which describe the Office of Hazardous Materials Transportation Label and Placard Color Tolerance Charts in tables 1 and 2, and the CIE coordinates for the color tolerances specified in table 3. Central colors and tolerances described in table 2 approximate those described in table 1 while allowing for differences in production methods and materials used to manufacture labels and placards surfaced with printing inks. Primarily, the color charts based on table 1 are for label or placard colors applied as opaque coatings such as paint, enamel or plastic, whereas color charts based on table 2 are intended for use with labels and placards surfaced only with inks.
For labels printed directly on packaging surfaces, table 3 may be used, although compliance with either table 1 or table 2 is sufficient. However, if visual reference indicates that the colors of labels printed directly on package surfaces are outside the table 1 or 2 tolerances, a spectrophotometer or other instrumentation may be required to insure compliance with table 3.

Appendix C to Part 172 – Dimensional Specifications for Recommended Placard Holder
Appendix D to Part 172 – Rail Risk Analysis Factors
A. This appendix sets forth the minimum criteria that must be considered by rail carriers when performing the safety and security risk analyses required by § 172.820. The risk analysis to be performed may be quantitative, qualitative, or a combination of both. In addition to clearly identifying the hazardous material(s) and route(s) being analyzed, the analysis must provide a thorough description of the threats, identified vulnerabilities, and mitigation measures implemented to address identified vulnerabilities.
B. In evaluating the safety and security of hazardous materials transport, selection of the route for transportation is critical. For the purpose of rail transportation route analysis, as specified in § 172.820(c) and (d), a route may include the point where the carrier takes possession of the material and all track and railroad facilities up to the point where the material is relinquished to another entity. Railroad facilities are railroad property including, but not limited to, classification and switching yards, storage facilities, and non-private sidings; however, they do not include an offeror’s facility, private track, private siding, or consignee’s facility. Each rail carrier must use best efforts to communicate with its shippers, consignees, and interlining partners to ensure the safety and security of shipments during all stages of transportation.
C. Because of the varying operating environments and interconnected nature of the rail system, each carrier must select and document the analysis method/model used and identify the routes to be analyzed.
D. The safety and security risk analysis must consider current data and information as well as changes that may reasonably be anticipated to occur during the analysis year. Factors to be considered in the performance of this safety and security risk analysis include:
1. Volume of hazardous material transported;
2. Rail traffic density;
3. Trip length for route;
4. Presence and characteristics of railroad facilities;
5. Track type, class, and maintenance schedule;
6. Track grade and curvature;
7. Presence or absence of signals and train control systems along the route (“dark” versus signaled territory);
8. Presence or absence of wayside hazard detectors;
9. Number and types of grade crossings;
10. Single versus double track territory;
11. Frequency and location of track turnouts;
12. Proximity to iconic targets;
13. Environmentally sensitive or significant areas;
14. Population density along the route;
15. Venues along the route (stations, events, places of congregation);
16. Emergency response capability along the route;
17. Areas of high consequence along the route, including high consequence targets as defined in § 172.820(c);
18. Presence of passenger traffic along route (shared track);
19. Speed of train operations;
20. Proximity to en-route storage or repair facilities;
21. Known threats, including any non-public threat scenarios provided by the Department of Homeland Security or the Department of Transportation for carrier use in the development of the route assessment;
22. Measures in place to address apparent safety and security risks;
23. Availability of practicable alternative routes;
24. Past incidents;
25. Overall times in transit;
26. Training and skill level of crews; and
27. Impact on rail network traffic and congestion.
PART 173 – SHIPPERS – GENERAL REQUIREMENTS FOR SHIPMENTS AND PACKAGINGS
Subpart A – General
§ 173.1 Purpose and scope.
(a) This part includes:
(1) Definitions of hazardous materials for transportation purposes;
(2) Requirements to be observed in preparing hazardous materials for shipment by air, highway, rail, or water, or any combination thereof; and
(3) Inspection, testing, and retesting responsibilities for persons who retest, recondition, maintain, repair and rebuild containers used or intended for use in the transportation of hazardous materials.
(b) A shipment of hazardous materials that is not prepared in accordance with this subchapter may not be offered for transportation by air, highway, rail, or water. It is the responsibility of each hazmat employer subject to the requirements of this subchapter to ensure that each hazmat employee is trained in accordance with the requirements prescribed in this subchapter. It is the duty of each person who offers hazardous materials for transportation to instruct each of his officers, agents, and employees having any responsibility for preparing hazardous materials for shipment as to applicable regulations in this subchapter.
(c) In general, the Hazardous Materials Regulations (HMR) contained in this subchapter are based on the UN Recommendations and are consistent with international regulations issued by the International Civil Aviation Organization (ICAO Technical Instructions) and the International Maritime Organization (IMDG Code). However, the HMR are not consistent in all respects with the UN Recommendations, the ICAO Technical Instructions or the IMDG Code, and compliance with the HMR will not guarantee acceptance by regulatory bodies outside of the United States.
§ 173.2 Hazardous materials classes and index to hazard class definitions.
The hazard class of a hazardous material is indicated either by its class (or division) number, its class name, or by the letters “ORM-D”.

§ 173.10 Tank car shipments.
(a) Tank cars containing any 2.1 material (including a cryogenic liquid) or Class 3 material with a flash point below 38 °C (100 °F), except liquid road asphalt or tar, may not be offered for transportation unless originally consigned or subsequently reconsigned to parties having private-siding (see Note 1 of this section) or to parties using railroad siding facilities which have been equipped for piping the liquid from tank cars to permanent storage tanks of sufficient capacity to receive contents of car.
(b) A tank car containing any Class 2 material must not be offered for transportation unless the car is consigned for delivery (see paragraph (c) of this section) and unloading on a private track (see Note 1 of this section) except that where no private track is available, delivery and unloading on carrier tracks is permitted provided the following conditions are complied with:
(1) Any tank car of DOT-106A or 110A type (see §§ 179.300 and 179.301 of this subchapter) may be offered for transportation and the loaded unit tanks may be removed from car frame on carrier tracks, provided the shipper has obtained from the delivering carrier and filed with originating carrier, written permission (see Note 2 of this section) for such removal. The consignee must furnish adequately safe mechanical hoist, obtained from the carrier if desirable, by which the tanks shall be lifted from the car and deposited directly upon vehicles furnished by the consignee for immediate removal from carrier property or tanks must be lifted by adequately safe mechanical hoist from car directly to vessels for further transportation.
(c) Any tank car of other than DOT-106A or 110A type (see §§ 179.300 and 179.301 of this subchapter), containing anhydrous ammonia, liquefied hydrocarbon or liquefied petroleum gas, and having interior pipes of liquid and gas discharge valves equipped with check valves, may be consigned for delivery and unloading on carrier tracks, if the lading is piped directly from the car to permanent storage tanks of sufficient capacity to receive the entire contents of the car. Such cars may also be consigned for storage on a private track or on a carrier track when designated by the carrier for such storage.
(d) For cars of the DOT-106A or 110A type (see §§ 179.300 and 179.301 of this subchapter), the tanks must be placed in position and attached to the car structure by the shipper.
(e) Class 3 materials with a flash point below 38 °C (100 °F) and Division 2.1 materials (including a cryogenic liquid) may not be loaded into tank cars on carrier property from tank trucks or drums.
For this purpose, a private track is a track outside of carrier’s right-of-way, yard, and terminals, and of which the carrier does not own either the rails, ties, roadbed or right-of-way; or a track or portion of a track which is devoted to the purpose of its user, either by lease or written agreement; in which case the lease or written agreement will be considered as equivalent to ownership.
Carriers should give permission for the unloading of these containers on carrier tracks only where no private siding is available within reasonable trucking distance of final destination. The danger involved is the release of compressed gases due to accidental damage to container in handling. The exposure to this danger decreases directly with the isolation of the unloading point.

(3) Refrigeration may be used as a means of stabilization only when approved by the Associate Administrator. Approvals issued by the Bureau of Explosives are no longer valid (see § 171.19 of this subchapter). Methods of stabilization approved by the Associate Administrator are as follows:
(i) For highway transportation:
(A) A material meeting the criteria of this paragraph (f) may be transported only in a transport vehicle, freight container, or motor vehicle equipped with a mechanical refrigeration unit, or loaded with a consumable refrigerant, capable of maintaining the inside temperature of the hazardous material at or below the control temperature required for the material during transportation.
(B) Each package containing a material meeting the criteria of this paragraph (f) must be loaded and maintained at or below the control temperature required for the material. The temperature of the material must be determined by appropriate means and entered on a written record at the time the packaging is loaded.
(C) The vehicle operator shall monitor the inside temperature of the transport vehicle, freight container, or motor vehicle and enter that temperature on a written record at the time the package is loaded and thereafter at intervals not exceeding two hours. Alternatively, a transport vehicle, freight container, or motor vehicle may be equipped with a visible or audible warning device that activates when the inside temperature of the transport vehicle, freight container, or motor vehicle exceeds the control temperature required for the material. The warning device must be readily visible or audible, as appropriate, from the vehicle operator’s seat in the vehicle.
(D) The carrier shall advise the vehicle operator of the emergency temperature for the material, and provide the vehicle operator with written procedures that must be followed to assure maintenance of the control temperature inside the transport vehicle, freight container, or motor vehicle. The written procedures must include instructions for the vehicle operator on actions to take if the inside temperature exceeds the control temperature and approaches or reaches the emergency temperature for the material. In addition, the written temperature-control procedures must identify enroute points where the consumable refrigerant may be procured, or where repairs to, or replacement of, the mechanical refrigeration unit may be accomplished.
(E) The vehicle operator shall maintain the written temperature-control procedures, and the written record of temperature measurements specified in paragraph (f)(3)(i)(C) of this section, if applicable, in the same manner as specified in § 177.817 of this subchapter for shipping papers.
(F) If the control temperature is maintained by use of a consumable refrigerant (e.g., dry ice or liquid nitrogen), the quantity of consumable refrigerant must be sufficient to maintain the control temperature for twice the average transit time under normal conditions of transportation.

Except for materials not subject to performance packaging requirements in subpart E of this part, a packaging containing a Packing Group III material with a primary or subsidiary risk of Division 4.1, 4.2, 4.3, 5.1, or Class 8 must meet the Packing Group II performance level when offered for transportation by aircraft.
(b) Packages authorized onboard aircraft. (1) When Column 9a of the § 172.101 table indicates that a material is “Forbidden”, that material may not be offered for transportation or transported aboard passenger-carrying aircraft.
(2) When Column 9b of the § 172.101 table indicates that a material is “Forbidden”, that material may not be offered for transportation or transported aboard aircraft.
(3) The maximum quantity of hazardous material in a package that may be offered for transportation or transported aboard a passenger-carrying aircraft or cargo aircraft may not exceed that quantity prescribed for the material in Column 9a or 9b, respectively, of the § 172.101 table.
(4) A package containing a hazardous material which is authorized aboard cargo aircraft but not aboard passenger aircraft must be labeled with the CARGO AIRCRAFT ONLY label required by § 172.402(c) of this subchapter and may not be offered for transportation or transported aboard passenger-carrying aircraft.
(c) Pressure requirements. (1) Packagings must be designed and constructed to prevent leakage that may be caused by changes in altitude and temperature during transportation aboard aircraft.
(2) Packagings for which retention of liquid is a basic function must be capable of withstanding without leakage the greater of –
(i) An internal pressure which produces a gauge pressure of not less than 75 kPa (11 psig) for liquids in Packing Group III of Class 3 or Division 6.1; or 95 kPa (14 psig) for other liquids; or
(ii) A pressure related to the vapor pressure of the liquid to be conveyed, determined by one of the following:
(A) The total gauge pressure measured in the receptacle (i.e., the vapor pressure of the material and the partial pressure of air or other inert gases, less 100 kPa (15 psia)) at 55 °C (131 °F), multiplied by a safety factor of 1.5; determined on the basis of a filling temperature of 15 °C (59 °F) and a degree of filling such that the receptacle is not completely liquid full at a temperature of 55 °C (131 °F) or less;
(B) 1.75 times the vapor pressure at 50 °C (122 °F) less 100 kPa (15 psia); or
(C) 1.5 times the vapor pressure at 55 °C (131 °) less 100 kPa (15 psia).
(3) Notwithstanding the provisions of paragraph (c)(2) of this section –
(i) Hazardous materials may be contained in an inner packaging which does not itself meet the pressure requirement provided that the inner packaging is packed within a supplementary packaging which does meet the pressure requirement and other applicable packaging requirements of this subchapter.
(ii) Packagings which are subject to the hydrostatic pressure test and marking requirements of §§ 178.605 and 178.503(a)(5), respectively, of this subchapter must have a marked test pressure of not less than 250 kPa (36 psig) for liquids in Packing Group I, 80 kPa (12 psig) for liquids in Packing Group III of Class 3 or Division 6.1, and 100 kPa (15 psig) for other liquids.
(d) Closures. The body and closure of any packaging must be constructed to be able to adequately resist the effects of temperature and vibration occurring in conditions normally incident to air transportation. Inner packaging or receptacle closures of combination packages containing liquids must be held securely, tightly and effectively in place by secondary means. Examples of such secondary methods include: Adhesive tape, friction sleeves, welding or soldering, locking wires, locking rings, induction heat seals, and child-resistant closures. The closure device must be designed so that it is unlikely that it can be incorrectly or incompletely closed. Closures must be as follows:
(1) Packing Group I. An inner packaging containing liquids of Packing Group I must have a secondary means of closure applied and packed in accordance with paragraph (e) of this section.
(2) Packing Groups II and III. When a secondary means of closure cannot be applied or is impracticable to apply to an inner packaging containing liquids of Packing Groups II and III, this requirement may be satisfied by securely closing the inner packaging and placing it in a leakproof liner or bag before placing the inner packaging in its outer packaging.
(e) Absorbent materials. Except as otherwise provided in this subchapter, Packing Group I liquid hazardous materials of Classes 3, 4, or 8, or Divisions 5.1 or 6.1 that are packaged in combination packagings and offered for air transport in glass, earthenware, plastic, or metal inner packagings must be packed using absorbent material as follows:
(1) Inner packagings must be packed in a rigid and leakproof receptacle or intermediate packaging containing sufficient absorbent material to absorb the entire contents of the inner packaging before packing the inner packaging in its outer package.
(2) Absorbent material must not react dangerously with the liquid (see §§ 173.24 and 173.24a.).
(f) Combination packagings – (1) Excepted quantities. For authorized materials and inner and outer package quantity limits for combination packages of excepted quantities intended for transportation by aircraft, see § 173.4a of this part. Unless otherwise specified in this part, or in Subpart C of part 171 of this subchapter, when combination packagings are intended for transportation aboard an aircraft, inner packagings must conform to the quantity limitations set forth in table 1 of this paragraph for transport aboard passenger-carrying aircraft and table 2 of this paragraph for transport aboard cargo-only aircraft.
(2) Limited quantities. (i) Unless otherwise specified in this part, or in subpart C of part 171 of this subchapter, when a limited quantity of hazardous material packaged in a combination packaging is intended for transportation aboard an aircraft, the inner and outer packagings must conform to the quantity limitations set forth in Table 3 of this paragraph (f). Materials and articles must be authorized for transportation aboard a passenger-carrying aircraft (see Column (9A) of the § 172.101 Hazardous Materials Table of this subchapter). Not all unauthorized materials or articles may be indicated in this table. For mixed content packages of limited quantity material, the total net quantity must not exceed the lowest permitted maximum net quantity (for each of the hazard classes or divisions represented in the package) per outer package set forth in Table 3 of this paragraph (f). The permitted maximum net quantity must be calculated in kilograms for a package that contains both a solid and a liquid. Unless otherwise excepted, packages must be marked and labeled in accordance with this section and any additional requirements in subparts D and E, respectively, of part 172 of this subchapter. Materials or articles not authorized as limited quantity by aircraft are:
(A) Those in Packing Group I;
(B) Class 1 (explosive) material (see § 173.63(b) of this part for exceptions provided to certain articles of Division 1.4S) and Class 7 (radioactive) material (see §§ 173.421 through 173.425 of this part, as applicable, for exceptions provided to certain substances, instruments or articles of Class 7);
(C) Divisions 2.1 (flammable gas) (except Aerosols (UN1950) and Receptacles, small (UN2037) without subsidiary risk) and Division 2.3 (toxic gas);
(D) Divisions 4.1 (self-reactive), 4.2 (spontaneously combustible) (primary or subsidiary risk), and 4.3 (dangerous when wet) (liquids);
(E) Division 5.2 (organic peroxide) (except when contained in a Chemical or First aid kit (UN3316) or Polyester resin kit (UN3269) (Types D, E and F non-temperature controlled only));
(F) Class 8 (corrosive) materials UN2794, UN2795, UN2803, UN2809, UN3028, UN3506; and

(ii) Packages must be marked with the limited quantity “Y” mark as prescribed in § 172.315 of this subchapter when conforming to Table 3 of this paragraph.
(iii) Strong outer packagings are required and a completed package may not exceed 30 kg (66 lbs) gross weight.
(iv) A secondary means of closure required for all liquids contained in inner packagings. If this requirement cannot be satisfied, the use of an intermediate and leakproof form of containment, such as a liner, is required.
(v) Packages must be capable of passing a 1.2 m drop test on to a rigid, non-resilient, flat and horizontal surface, in the position most likely to cause damage. The criteria for passing the test is that the outer packaging must not exhibit any damage affecting safety in transport and there must be no leakage from the inner packagings.
(vi) Each package must be capable of withstanding, without breakage or leakage of any inner packaging, a force applied to the top surface for a duration of 24 hours equivalent to the total weight of identical packages if stacked to a height of 3 m (including the test sample).
(vii) Except for UN3082, inner packagings of combination packagings containing liquids must be capable of passing the appropriate pressure differential test prescribed in paragraph (c) of this section.

(C) Another material or thickness when approved under the conditions established by the Associate Administrator for reuse without retesting.
(c) Reconditioning of non-bulk packaging. (1) For the purpose of this subchapter, reconditioning of metal drums is:
(i) Cleaning to base material of construction, with all former contents, internal and external corrosion removed, and any external coatings and labels sufficiently removed to expose any metal deterioration that adversely affects transportation safety;
(ii) Restoring to original shape and contour, with chimes (if any) straightened and sealed, and all non-integral gaskets replaced: and
(iii) Inspecting after cleaning but before painting, Packagings that have visible pitting, significant reduction in material thickness, metal fatigue, damaged threads or closures, or other significant defects, must be rejected.
(2) For the purpose of this subchapter, reconditioning of a non-bulk packaging other than a metal drum includes:
(i) Removal of all former contents, external coatings and labels, and cleaning to the original materials of construction;
(ii) Inspection after cleaning with rejection of packagings with visible damage such as tears, creases or cracks, or damaged threads or closures, or other significant defects;
(iii) Replacement of all non-integral gaskets and closure devices with new or refurbished parts, and cushioning and cushioning materials; and components including gaskets, closure devices and cushioning and cushioning material. (For a UN 1H1 plastic drum, replacing a removable gasket or closure device with another of the same design and material that provides equivalent performance does not constitute reconditioning); and
(iv) Ensuring that the packagings are restored to a condition that conforms in all respects with the prescribed requirements of this subchapter.
(3) A person who reconditions a packaging manufactured and marked under the provisions of subpart L of part 178 of this subchapter, shall mark that packaging as required by § 178.503(c) and (d) of this subchapter. The marking is the certification of the reconditioner that the packaging conforms to the standard for which it is marked and that all functions performed by the reconditioner which are prescribed by this subchapter have been performed in compliance with this subchapter.
(4) The markings applied by the reconditioner may be different from those applied by the manufacturer at the time of original manufacture, but may not identify a greater performance capability than that for which the original design type had been tested (for example, the reconditioner may mark a drum which was originally marked as 1A1/Y1.8 as 1A1/Y1.2 or 1A1/Z2.0).
(5) Packagings which have significant defects which cannot be repaired may not be reused.
(d) Remanufacture of non-bulk packagings. For the purpose of this subchapter, remanufacture is the conversion of a non-specification, non-bulk packaging to a DOT specification or U.N. standard, the conversion of a packaging meeting one specification or standard to another specification or standard (for example, conversion of 1A1 non-removable head drums to 1A2 removable head drums) or the replacement of integral structural packaging components (such as non-removable heads on drums). A person who remanufactures a non-bulk packaging to conform to a specification or standard in part 178 of this subchapter is subject to the requirements of part 178 of this subchapter as a manufacturer.
(e) Non-reusable containers. A packaging marked as NRC according to the DOT specification or UN standard requirements of part 178 of this subchapter may be reused for the shipment of any material not required by this subchapter to be shipped in a DOT specification or UN standard packaging.
(f) A Division 6.2 packaging to be reused must be disinfected prior to reuse by any means effective for neutralizing the infectious substance the packaging previously contained. A secondary packaging or outer packaging conforming to the requirements of § 173.196 or § 173.199 need not be disinfected prior to reuse if no leakage from the primary receptacle has occurred. Drums or jerricans not meeting the minimum thickness requirements prescribed in paragraph (b)(4)(i) of this section may not be reused or reconditioned for reuse.
§ 173.29 Empty packagings.
(a) General. Except as otherwise provided in this section, an empty packaging containing only the residue of a hazardous material shall be offered for transportation and transported in the same manner as when it previously contained a greater quantity of that hazardous material.

(4) The minimum pressure prescribed by the specification in part 179 of this subchapter; or
(5) The minimum test pressure prescribed for the specific hazardous material in the applicable packaging section in subpart F or G of this part.
(d) Examination before shipping. (1) No person may offer for transportation a tank car containing a hazardous material or a residue of a hazardous material unless that person determines that the tank car is in proper condition and safe for transportation. As a minimum, each person offering a tank car for transportation must perform an external visual inspection that includes:
(i) Except where insulation or a thermal protection system precludes an inspection, the tank shell and heads for abrasion, corrosion, cracks, dents, distortions, defects in welds, or any other condition that makes the tank car unsafe for transportation;
(ii) The piping, valves, fittings, and gaskets for corrosion, damage, or any other condition that makes the tank car unsafe for transportation;
(iii) For missing or loose bolts, nuts, or elements that make the tank car unsafe for transportation;

The term includes a pyrotechnic substance or article, unless the substance or article is otherwise classed under the provisions of this subchapter.
(b) Explosives in Class 1 are divided into six divisions as follows:
(1) Division 1.1 consists of explosives that have a mass explosion hazard. A mass explosion is one which affects almost the entire load instantaneously.
(2) Division 1.2 consists of explosives that have a projection hazard but not a mass explosion hazard.
(3) Division 1.3 consists of explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard.
(4) Division 1.4 consists of explosives that present a minor explosion hazard. The explosive effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire must not cause virtually instantaneous explosion of almost the entire contents of the package.
(5) Division 1.5
(6) Division 1.6
§ 173.51 Authorization to offer and transport explosives.
(a) Unless otherwise provided in this subpart, no person may offer for transportation or transport an explosive, unless it has been tested and classed and approved by the Associate Administrator (§ 173.56).
(b) Reports of explosives approved by the Department of Defense or the Department of Energy must be filed with, and receive acknowledgement in writing by, the Associate Administrator prior to such explosives being offered for transportation.
§ 173.52 Classification codes and compatibility groups of explosives.
(a) The classification code for an explosive, which is assigned by the Associate Administrator in accordance with this subpart, consists of the division number followed by the compatibility group letter. Compatibility group letters are used to specify the controls for the transportation, and storage related thereto, of explosives and to prevent an increase in hazard that might result if certain types of explosives were stored or transported together. Transportation compatibility requirements for carriers are prescribed in §§ 174.81, 175.78. 176.83 and 177.848 of this subchapter for transportation by rail, air, vessel, and public highway, respectively, and storage incidental thereto.
(b) Compatibility groups and classification codes for the various types of explosives are set forth in the following tables. Table 1 sets forth compatibility groups and classification codes for substances and articles described in the first column of table 1. Table 2 shows the number of classification codes that are possible within each explosive division. Altogether, there are 35 possible classification codes for explosives.

Fuse/Fuze. Although these two words have a common origin (French fusee, fusil) and are sometimes considered to be different spellings, it is useful to maintain the convention that fuse refers to a cord-like igniting device, whereas fuze refers to a device used in ammunition which incorporates mechanical, electrical, chemical, or hydrostatic components to initiate a train by deflagration or detonation.
Fuse, igniter. Articles consisting of a metal tube with a core of deflagrating explosives.

Initiation, means of. (1) A device intended to cause the detonation of an explosive (for example: detonator, detonator for ammunition, or detonating fuze).
(2) The term with its own means of initiation means that the contrivance has its normal initiating device assembled to it and this device is considered to present a significant risk during transport but not one great enough to be unacceptable. The term does not apply, however, to a contrivance packed together with its means of initiation, provided the device is packaged so as to eliminate the risk of causing detonation of the contrivance in the event of functioning of the initiating device. The initiating device can even be assembled in the contrivance provided there are protective features ensuring that the device is very unlikely to cause detonation of the contrivance under conditions which are associated with transport.
(3) For the purposes of classification, any means of initiation without two effective protective features should be regarded as Compatibility Group B; an article with its own means of initiation, without two effective protective features, is Compatibility Group F. A means of initiation which itself possesses two effective protective features is Compatibility Group D, and an article with its own means of initiation which possesses two effective features is Compatibility Group D or E. A means of initiation, adjudged as having two effective protective features, must be approved by the Associate Administrator. A common and effective way of achieving the necessary degree of protection is to use a means of initiation which incorporates two or more independent safety features.

The phlegmatizer renders the explosive insensitive, or less sensitive, to the following actions: heat, shock, impact, percussion or friction. Typical phlegmatizing agents include, but are not limited to: wax, paper, water, polymers (such as chlorofluoropolymers), alcohol and oils (such as petroleum jelly and paraffin).
Powder cake (powder paste). Substance consisting of nitrocellulose impregnated with not more than 60 percent of nitroglycerin or other liquid organic nitrates or a mixture of these.
Powder, smokeless. Substance based on nitrocellulose used as propellant. The term includes propellants with a single base (nitrocellulose (NC) alone), those with a double base (such as NC and nitroglycerin (NG)) and those with a triple base (such as NC/NG/nitroguanidine). Cast pressed or bag-charges of smokeless powder are listed under charges, propelling and charges, propelling for cannon.

§ 173.60 General packaging requirements for explosives.
(a) Unless otherwise provided in this subpart and in § 173.7(a), packaging used for Class 1 (explosives) materials must meet Packing Group II requirements. Each packaging used for an explosive must be capable of meeting the test requirements of subpart M of part 178 of this subchapter, at the specified level of performance, and the applicable general packaging requirements of paragraph (b) of this section.
(b) The general requirements for packaging of explosives are as follows:
(1) Nails, staples, and other closure devices, made of metal, having no protective covering may not penetrate to the inside of the outer packaging unless the inner packaging adequately protects the explosive against contact with the metal.
(2) The closure device of containers for liquid explosives must provide double protection against leakage, such as a screw cap secured in place with tape.
(3) Inner packagings, fittings, and cushioning materials, and the placing of explosive substances or articles in packages, must be such that the explosive substance is prevented from becoming loose in the outer packaging during transportation. Metallic components of articles must be prevented from making contact with metal packagings. Articles containing explosive substances not enclosed in an outer casing must be separated from each other in order to prevent friction and impact. Padding, trays, partitioning in the inner or outer packaging, molded plastics or receptacles may be used for this purpose.
(4) When the packaging includes water that could freeze during transportation, a sufficient amount of anti-freeze, such as denatured ethyl alcohol, must be added to the water to prevent freezing. If the anti-freeze creates a fire hazard, it may not be used. When a percentage of water in the substance is specified, the combined weight of water and anti-freeze may be substituted.
(5) If an article is fitted with its own means of ignition or initiation, it must be effectively protected from accidental actuation during normal conditions of transportation.
(6) The entry of explosive substances into the recesses of double-seamed metal packagings must be prevented.
(7) The closure device of a metal drum must include a suitable gasket; if the closure device includes metal-to-metal screw-threads, the ingress of explosive substances into the threading must be prevented.
(8) Whenever loose explosive substances or the explosive substance of an uncased or partly cased article may come into contact with the inner surface of metal packagings (1A2, 1B2, 4A, 4B and metal receptacles), the metal packaging should be provided with an inner liner or coating.
(9) Packagings must be made of materials compatible with, and impermeable to, the explosives contained in the package, so that neither interaction between the explosives and the packaging materials, nor leakage, causes the explosive to become unsafe in transportation, or the hazard division or compatibility group to change (see § 173.24(e)(2)).
(10) An explosive article containing an electrical means of initiation that is sensitive to external electromagnetic radiation, must have its means of initiation effectively protected from electromagnetic radiation sources (for example, radar or radio transmitters) through either design of the packaging or of the article, or both.
(11) Plastic packagings may not be able to generate or accumulate sufficient static electricity to cause the packaged explosive substances or articles to initiate, ignite or inadvertently function. Metal packagings must be compatible with the explosive substance they contain.
(12) Explosive substances may not be packed in inner or outer packagings where the differences in internal and external pressures, due to thermal or other effects, could cause an explosion or rupture of the package.
(13) Packagings for water soluble substances must be water resistant. Packagings for desensitized or phlegmatized substances must be closed to prevent changes in concentration during transport. When containing less alcohol, water, or phlegmatizer than specified in its proper shipping description, the substance is a “forbidden” material.
(14) Large and robust explosives articles, normally intended for military use, without their means of initiation or with their means of initiation containing at least two effective protective features, may be carried unpackaged provided that a negative result was obtained in Test Series 4 of the UN Manual of Tests and Criteria on an unpackaged article. When such articles have propelling charges or are self-propelled, their ignition systems must be protected against conditions encountered during normal transportation. Such unpackaged articles may be fixed to cradles or contained in crates or other suitable handling, storage or launching devices in such a way that they will not become loose during normal conditions of transport and are in accordance with DOD-approved procedures. When such large explosive articles, as part of their operational safety and suitability tests, are subjected to testing that meets the intentions of Test Series 4 of the UN Manual of Tests and Criteria with successful test results, they may be offered for transportation in accordance with the requirements prescribed in (b)(14) above subject to approval by the Associate Administrator.
§ 173.61 Mixed packaging requirements.
(a) An explosive may not be packed in the same outside packaging with any other material that could, under normal conditions of transportation, adversely affect the explosive or its packaging unless packaged by DOD or DOE in accordance with § 173.7(a).
(b) Hardware necessary for assembly of explosive articles at the point-of-use may be packed in the same outside packaging with the explosive articles. The hardware must be securely packed in a separate inside packaging. Sufficient cushioning materials must be used to ensure that all inside packagings are securely packed in the outside packaging.
(c) The following explosives may not be packed together with other Class 1 explosives: UN 0029, UN 0030, UN 0073, UN 0106, UN 0107, UN 0255, UN 0257, UN 0267, UN 0350, UN 0360, UN 0361, UN 0364, UN 0365, UN 0366, UN 0367, UN 0408, UN 0409, UN 0410, UN 0455, UN 0456, and UN 0500. These explosives may be mix-packed with each other in accordance with the compatibility requirements prescribed in paragraph (e) of this section.
(d) Division 1.1 and 1.2 explosives may not be packed with the following explosives: UN 0333, UN 0334, UN 0335, UN 0336, and UN 0337.
(e) Except as prescribed in paragraphs (c) and (d) of this section, different explosives may be packed in one outside packaging in accordance with the following compatibility requirements:
(1) Explosives of the same compatibility group and same division number may be packed together.
(2) Explosives of the same compatibility group or authorized combination of compatibility group but different division number may be packed together, provided that the whole package is treated as though its entire contents were comprised of the lower division number. For example, a mixed package of Division 1.2 explosives and Division 1.4 explosives, compatibility group D, must be treated as 1.2D explosives. However, when 1.5D explosives are packed together with 1.2D explosives, the whole package must be treated as 1.1D explosives.
(3) Explosives of compatibility group S may be packaged together with explosives of any other compatibility group except A or L, and the combined package may be treated as belonging to any of the packaged compatibility groups except S.
(4) Explosives of compatibility group L shall only be packed with an identical explosive.
(5) Explosives articles of compatibility groups C, D, or E may be packed together and the entire package shall be treated as belonging to compatibility group E.
(6) Explosives articles of compatibility groups C, D, E, or N may be packed together and the entire package shall be treated as belonging to compatibility group D.
(7) Explosives substances of compatibility groups C and D may be packaged together and the entire package shall be treated as belonging to compatibility group D.
(8) Explosive articles of compatibility group G, except for fireworks and articles requiring special packaging, may be packaged together with explosive articles of compatibility groups C, D or E and the combined package shall be treated as belonging to compatibility group E.
§ 173.62 Specific packaging requirements for explosives.
(a) Except as provided in § 173.7 of this subchapter, when the § 172.101 Table specifies that an explosive must be packaged in accordance with this section, only packagings which conform to the provisions of paragraphs (b) and (c) of this section or § 173.7(e) of this subchapter and the applicable requirements in §§ 173.60 and 173.61 may be used unless otherwise approved by the Associate Administrator.
(b) Explosives Table. The Explosives Table specifies the Packing Instructions assigned to each explosive. Explosives are identified in the first column in numerical sequence by their identification number (ID #), which is listed in column 4 of the § 172.101 table, of this subchapter. The second column of the Explosives Table specifies the Packing Instruction (PI) which must be used for packaging the explosive. The Explosives Packing Method Table in paragraph (c) of this section defines the methods of packaging. The Packing Instructions are identified using a 3 digit designation. The Packing Instruction prefixed by the letters “US” is particular to the United States and not found in applicable international regulations.

This provision does not apply to transportation by vessel or aircraft, except where other means of transportation is impracticable. An elevated temperature material that meets the definition of a Class 3 material because it is intentionally heated and offered for transportation or transported at or above its flash point may not be reclassed as a combustible liquid.
(3) A combustible liquid that does not sustain combustion is not subject to the requirements of this subchapter as a combustible liquid. Either the test method specified in ASTM D 4206 or the procedure in appendix H of this part may be used to determine if a material sustains combustion when heated under test conditions and exposed to an external source of flame.
(c) Flash point. (1) Flash point means the minimum temperature at which a liquid gives off vapor within a test vessel in sufficient concentration to form an ignitable mixture with air near the surface of the liquid. It shall be determined as follows:
(i) For a homogeneous, single-phase, liquid having a viscosity less than 45 S.U.S. at 38 °C (100 °F) that does not form a surface film while under test, one of the following test procedures shall be used:

If it is determined by this test that the flash point is higher than −7 °C (20 °F) a second test shall be made as follows: a portion of the mixture shall be placed in an open beaker (or similar container) of such dimensions that the height of the liquid can be adjusted so that the ratio of the volume of the liquid to the exposed surface area is 6 to one. The liquid shall be allowed to evaporate under ambient pressure and temperature (20 to 25 °C (68 to 77 °F)) for a period of 4 hours or until 10 percent by volume has evaporated, whichever comes first. A flash point is then run on a portion of the liquid remaining in the evaporation container and the lower of the two flash points shall be the flash point of the material.
(3) For flash point determinations by Setaflash closed tester, the glass syringe specified need not be used as the method of measurement of the test sample if a minimum quantity of 2 mL (0.1 ounce) is assured in the test cup.
(d) If experience or other data indicate that the hazard of a material is greater or less than indicated by the criteria specified in paragraphs (a) and (b) of this section, the Associate Administrator may revise the classification or make the material subject or not subject to the requirements of parts 171 through 185 of this subchapter.

(b) Generic types. Division 5.2 organic peroxides are assigned to a generic system which consists of seven types. An organic peroxide identified by technical name in the Organic Peroxides Table in § 173.225 is assigned to a generic type in accordance with that table. Organic peroxides not identified in the Organic Peroxides table are assigned to generic types under the procedures of paragraph (c) of this section.
(1) Type A. Organic peroxide type A is an organic peroxide which can detonate or deflagrate rapidly as packaged for transport. Transportation of type A organic peroxides is forbidden.
(2) Type B. Organic peroxide type B is an organic peroxide which, as packaged for transport, neither detonates nor deflagrates rapidly, but can undergo a thermal explosion.
(3) Type C. Organic peroxide type C is an organic peroxide which, as packaged for transport, neither detonates nor deflagrates rapidly and cannot undergo a thermal explosion.
(4) Type D. Organic peroxide type D is an organic peroxide which –
(i) Detonates only partially, but does not deflagrate rapidly and is not affected by heat when confined;
(ii) Does not detonate, deflagrates slowly, and shows no violent effect if heated when confined; or
(iii) Does not detonate or deflagrate, and shows a medium effect when heated under confinement.
(5) Type E. Organic peroxide type E is an organic peroxide which neither detonates nor deflagrates and shows low, or no, effect when heated under confinement.
(6) Type F. Organic peroxide type F is an organic peroxide which will not detonate in a cavitated state, does not deflagrate, shows only a low, or no, effect if heated when confined, and has low, or no, explosive power.
(7) Type G. Organic peroxide type G is an organic peroxide which will not detonate in a cavitated state, will not deflagrate at all, shows no effect when heated under confinement, and shows no explosive power. A type G organic peroxide is not subject to the requirements of this subchapter for organic peroxides of Division 5.2 provided that it is thermally stable (self-accelerating decomposition temperature is 50 °C (122 °F) or higher for a 50 kg (110 pounds) package). An organic peroxide meeting all characteristics of type G except thermal stability and requiring temperature control is classed as a type F, temperature control organic peroxide.
(c) Procedure for assigning an organic peroxide to a generic type. An organic peroxide shall be assigned to a generic type based on –
(1) Its physical state (i.e., liquid or solid), in accordance with the definitions for liquid and solid in § 171.8 of this subchapter;
(2) A determination as to its control temperature and emergency temperature, if any, under the provisions of § 173.21(f); and
(3) Performance of the organic peroxide under the test procedures specified in the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter), and the provisions of paragraph (d) of this section.
(d) Approvals. (1) An organic peroxide must be approved, in writing, by the Associate Administrator, before being offered for transportation or transported, including assignment of a generic type and shipping description, except for –
(i) An organic peroxide which is identified by technical name in the Organic Peroxides Table in § 173.225(c);
(ii) A mixture of organic peroxides prepared according to § 173.225(b); or

§ 173.132 Class 6, Division 6.1 – Definitions.
(a) For the purpose of this subchapter, poisonous material (Division 6.1) means a material, other than a gas, which is known to be so toxic to humans as to afford a hazard to health during transportation, or which, in the absence of adequate data on human toxicity:
(1) Is presumed to be toxic to humans because it falls within any one of the following categories when tested on laboratory animals (whenever possible, animal test data that has been reported in the chemical literature should be used):
(i) Oral Toxicity. A liquid or solid with an LD
(ii) Dermal Toxicity. A material with an LD
(iii) Inhalation Toxicity. (A) A dust or mist with an LC
(B) A material with a saturated vapor concentration in air at 20 °C (68 °F) greater than or equal to one-fifth of the LC
(2) Is an irritating material, with properties similar to tear gas, which causes extreme irritation, especially in confined spaces.
(b) For the purposes of this subchapter –
(1) LD
(2) LD
(3) LC
(i) When provisions of this subchapter require the use of the LC
(ii) When the provisions of this subchapter require the use of the LC
(iii) A solid substance should be tested if at least 10 percent of its total mass is likely to be dust in a respirable range, e.g. the aerodynamic diameter of that particle-fraction is 10 microns or less. A liquid substance should be tested if a mist is likely to be generated in a leakage of the transport containment. In carrying out the test both for solid and liquid substances, more than 90% (by mass) of a specimen prepared for inhalation toxicity testing must be in the respirable range as defined in this paragraph (b)(3)(iii).
(c) For purposes of classifying and assigning packing groups to mixtures possessing oral or dermal toxicity hazards according to the criteria in § 173.133(a)(1), it is necessary to determine the acute LD
(1) Obtain reliable acute oral and dermal toxicity data on the actual mixture to be transported;
(2) If reliable, accurate data is not available, classify the formulation according to the most hazardous constituent of the mixture as if that constituent were present in the same concentration as the total concentration of all active constituents; or
(3) If reliable, accurate data is not available, apply the formula:
This formula also may be used for dermal toxicities provided that this information is available on the same species for all constituents. The use of this formula does not take into account any potentiation or protective phenomena.
(d) The foregoing categories shall not apply if the Associate Administrator has determined that the physical characteristics of the material or its probable hazards to humans as shown by documented experience indicate that the material will not cause serious sickness or death.

§ 173.134 Class 6, Division 6.2 – Definitions and exceptions.
(a) Definitions and classification criteria. For the purposes of this subchapter, the following definitions and classification criteria apply to Division 6.2 materials.
(1) Division 6.2 (Infectious substance) means a material known or reasonably expected to contain a pathogen. A pathogen is a microorganism (including bacteria, viruses, rickettsiae, parasites, fungi) or other agent, such as a proteinaceous infectious particle (prion), that can cause disease in humans or animals. An infectious substance must be assigned the identification number UN 2814, UN 2900, UN 3373, or UN 3291 as appropriate, and must be assigned to one of the following categories:
(i) Category A: An infectious substance in a form capable of causing permanent disability or life-threatening or fatal disease in otherwise healthy humans or animals when exposure to it occurs. An exposure occurs when an infectious substance is released outside of its protective packaging, resulting in physical contact with humans or animals. A Category A infectious substance must be assigned to identification number UN 2814 or UN 2900, as appropriate. Assignment to UN 2814 or UN 2900 must be based on the known medical history or symptoms of the source patient or animal, endemic local conditions, or professional judgment concerning the individual circumstances of the source human or animal.
(ii) Category B: An infectious substance that is not in a form generally capable of causing permanent disability or life-threatening or fatal disease in otherwise healthy humans or animals when exposure to it occurs. This includes Category B infectious substances transported for diagnostic or investigational purposes. A Category B infectious substance must be described as “Biological substance, Category B” and assigned identification number UN 3373. This does not include regulated medical waste, which must be assigned identification number UN 3291.
(2) Biological product means a virus, therapeutic serum, toxin, antitoxin, vaccine, blood, blood component or derivative, allergenic product, or analogous product, or arsphenamine or derivative of arsphenamine (or any other trivalent arsenic compound) applicable to the prevention, treatment, or cure of a disease or condition of human beings or animals. A biological product includes a material subject to regulation under 42 U.S.C. 262 or 21 U.S.C. 151-159. Unless otherwise excepted, a biological product known or reasonably expected to contain a pathogen that meets the definition of a Category A or B infectious substance must be assigned the identification number UN 2814, UN 2900, or UN 3373, as appropriate.
(3) Culture means an infectious substance containing a pathogen that is intentionally propagated. Culture does not include a human or animal patient specimen as defined in paragraph (a)(4) of this section.
(4) Patient specimens means those collected directly from humans or animals and transported for research, diagnosis, investigational activities, or disease treatment or prevention. Patient specimens includes excreta, secreta, blood and its components, tissue and tissue swabs, body parts, and specimens in transport media (e.g., transwabs, culture media, and blood culture bottles).
(5) Regulated medical waste or clinical waste or (bio) medical waste means a waste or reusable material derived from the medical treatment of an animal or human, which includes diagnosis and immunization, or from biomedical research, which includes the production and testing of biological products. Regulated medical waste or clinical waste or (bio) medical waste containing a Category A infectious substance must be classed as an infectious substance, and assigned to UN2814 or UN2900, as appropriate.
(6) Sharps means any object contaminated with a pathogen or that may become contaminated with a pathogen through handling or during transportation and also capable of cutting or penetrating skin or a packaging material. Sharps includes needles, syringes, scalpels, broken glass, culture slides, culture dishes, broken capillary tubes, broken rigid plastic, and exposed ends of dental wires.
(7) Toxin means a Division 6.1 material from a plant, animal, or bacterial source. A toxin containing an infectious substance or a toxin contained in an infectious substance must be classed as Division 6.2, described as an infectious substance, and assigned to UN 2814 or UN 2900, as appropriate.
(8) Used health care product means a medical, diagnostic, or research device or piece of equipment, or a personal care product used by consumers, medical professionals, or pharmaceutical providers that does not meet the definition of a patient specimen, biological product, or regulated medical waste, is contaminated with potentially infectious body fluids or materials, and is not decontaminated or disinfected to remove or mitigate the infectious hazard prior to transportation.
(b) Exceptions. The following are not subject to the requirements of this subchapter as Division 6.2 materials:
(1) A material that does not contain an infectious substance or that is unlikely to cause disease in humans or animals.
(2) Non-infectious biological materials from humans, animals, or plants. Examples include non-infectious cells, tissue cultures, blood or plasma from individuals not suspected of having an infectious disease, DNA, RNA or other non-infectious genetic elements.
(3) A material containing micro-organisms that are non-pathogenic to humans or animals.
(4) A material containing pathogens that have been neutralized or inactivated such that they no longer pose a health risk.
(5) A material with a low probability of containing an infectious substance, or where the concentration of the infectious substance is at a level naturally occurring in the environment so it cannot cause disease when exposure to it occurs. Examples of these materials include: Foodstuffs; environmental samples, such as water or a sample of dust or mold; and substances that have been treated so that the pathogens have been neutralized or deactivated, such as a material treated by steam sterilization, chemical disinfection, or other appropriate method, so it no longer meets the definition of an infectious substance.

§ 173.136 Class 8 – Definitions.
(a) For the purpose of this subchapter, “corrosive material” (Class 8) means a liquid or solid that causes irreversible damage to human skin at the site of contact within a specified period of time. A liquid, or a solid which may become liquid during transportation, that has a severe corrosion rate on steel or aluminum based on the criteria in § 173.137(c)(2) is also a corrosive material. Whenever practical, in vitro test methods authorized in § 173.137 of this part or historical data authorized in paragraph (c) of this section should be used to determine whether a material is corrosive.
(b) If human experience or other data indicate that the hazard of a material is greater or less than indicated by the results of the tests specified in paragraph (a) of this section, PHMSA may revise its classification or make the determination that the material is not subject to the requirements of this subchapter.
(c) Skin corrosion test data produced no later than September 30, 1995, using the procedures of part 173, appendix A, in effect on September 30, 1995 (see 49 CFR part 173, appendix A, revised as of October 1, 1994) for appropriate exposure times may be used for classification and assignment of packing group for Class 8 materials corrosive to skin.
§ 173.137 Class 8 – Assignment of packing group.
The packing group of a Class 8 material is indicated in Column 5 of the § 172.101 Table. When the § 172.101 Table provides more than one packing group for a Class 8 material, the packing group must be determined using data obtained from tests conducted in accordance with the OECD Guidelines for the Testing of Chemicals, Number 435, “In Vitro Membrane Barrier Test Method for Skin Corrosion” (IBR, see § 171.7 of this subchapter) or Number 404, “Acute Dermal Irritation/Corrosion” (IBR, see § 171.7 of this subchapter). A material that is determined not to be corrosive in accordance with OECD Guideline for the Testing of Chemicals, Number 430, “In Vitro Skin Corrosion: Transcutaneous Electrical Resistance Test (TER)” (IBR, see § 171.7 of this subchapter) or Number 431, “In Vitro Skin Corrosion: Reconstructed Human Epidermis (RHE) Test Method” (IBR, see § 171.7 of this subchapter) may be considered not to be corrosive to human skin for the purposes of this subchapter without further testing. However, a material determined to be corrosive in accordance with Number 430 or Number 431 must be further tested using Number 435 or Number 404. The packing group assignment using data obtained from tests conducted in accordance with OECD Guideline Number 404 or Number 435 must be as follows:
(a) Packing Group I. Materials that cause irreversible damage to intact skin tissue within an observation period of up to 60 minutes, starting after the exposure time of three minutes or less.
(b) Packing Group II. Materials, other than those meeting Packing Group I criteria, that cause irreversible damage to intact skin tissue within an observation period of up to 14 days, starting after the exposure time of more than three minutes but not more than 60 minutes.
(c) Packing Group III. Materials, other than those meeting Packing Group I or II criteria –
(1) That cause irreversible damage to intact skin tissue within an observation period of up to 14 days, starting after the exposure time of more than 60 minutes but not more than 4 hours; or
(2) That do not cause irreversible damage to intact skin tissue but exhibit a corrosion on either steel or aluminum surfaces exceeding 6.25 mm (0.25 inch) a year at a test temperature of 55 °C (130 °F) when tested on both materials. The corrosion may be determined in accordance with the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter) or other equivalent test methods.
(d) Alternative packing group assignment methods for mixtures. For mixtures it is necessary to obtain or derive information that allows the criteria to be applied to the mixture for the purpose of classification and assignment of packing groups. The approach to classification and assignment of packing groups is tiered, and is dependent upon the amount of information available for the mixture itself, for similar mixtures and/or for its ingredients. The flow chart in Figure 1 to paragraph (d) outlines the process to be followed:
(1) Bridging principles. Where a mixture has not been tested to determine its skin corrosion potential, but there is sufficient data on both the individual ingredients and similar tested mixtures to adequately classify and assign a packing group for the mixture, this data will be used in accordance with the following bridging principles. This ensures that the classification process uses the available data to the greatest extent possible in characterizing the hazards of the mixture.
(i) Dilution. If a tested mixture is diluted with a diluent, which does not meet the criteria for Class 8 and does not affect the packing group of other ingredients, then the new diluted mixture may be assigned to the same packing group as the original tested mixture. In certain cases, diluting a mixture or substance may lead to an increase in the corrosive properties. If this is the case, this bridging principle cannot be used.
(ii) Batching. The skin corrosion potential of a tested production batch of a mixture can be assumed to be substantially equivalent to that of another untested production batch of the same commercial product when produced by or under the control of the same manufacturer, unless there is reason to believe there is significant variation such that the skin corrosion potential of the untested batch has changed. If the latter occurs, a new classification is necessary.
(iii) Concentration of mixtures of packing group I. If a tested mixture meeting the criteria for inclusion in Packing Group I is concentrated, the more concentrated untested mixture may be assigned to Packing Group I without additional testing.
(iv) Interpolation within one packing group. For three mixtures (A, B and C) with identical ingredients, where mixtures A and B have been tested and are in the same skin corrosion packing group, and where untested mixture C has the same Class 8 ingredients as mixtures A and B but has concentrations of Class 8 ingredients intermediate to the concentrations in mixtures A and B, then mixture C is assumed to be in the same skin corrosion packing group as A and B.
(v) Substantially similar mixtures. Given the following:
(A) Two mixtures: (A+B) and (C+B);
(B) The concentration of ingredient B is the same in both mixtures;
(C) The concentration of ingredient A in mixture (A+B) equals the concentration of ingredient C in mixture (C+B);
(D) Data on skin corrosion for ingredients A and C are available and substantially equivalent, i.e., they are the same skin corrosion packing group and do not affect the skin corrosion potential of B.
(E) If the above mixture (A+B) or (C+B) is already classified based on test data, then the other mixture may be assigned to the same packing group.
(2) Calculation method based on the classification of the substances. Where a mixture has not been tested to determine its skin corrosion potential, nor is sufficient data available on similar mixtures, the corrosive properties of the substances in the mixture shall be considered to classify and assign a packing group. Applying the calculation method is only allowed if there are no synergistic effects that make the mixture more corrosive than the sum of its substances. This restriction applies only if Packing Group II or III would be assigned to the mixture.
(i) All Class 8 ingredients present at a concentration of ≥1% shall be taken into account, or
(ii) To determine whether a mixture containing corrosive substances must be considered a corrosive mixture and to assign a packing group, the calculation method in the flow chart in appendix I must be applied. For this calculation method, generic concentration limits apply where 1% is used in the first step for the assessment of the packing group I substances, and where 5% is used for the other steps respectively.
(iii) When a specific concentration limit (SCL) is assigned to a substance following its entry in the Hazardous Materials Table or in a special provision, this limit shall be used instead of the generic concentration limits (GCL).
(iv) The following formula must be used for each step of the calculation process. The criterion for a packing group is fulfilled when the result of the calculation is ≥ 1. The generic concentration limits to be used for the evaluation in each step of the calculation method are those found in appendix I of this part. Where applicable, the generic concentration limit shall be substituted by the specific concentration limit assigned to the substance(s) (SCLi), and the adapted formula is a weighted average of the different concentration limits assigned to the different substances in the mixture:
When an initial test on either a steel or aluminum surface indicates the material being tested is corrosive, the follow up test on the other surface is not required.

§ 173.166 Safety devices.
For the purpose of this section, safety devices are articles which contain pyrotechnic substances or hazardous materials of other classes and are used in vehicles, vessels or aircraft to enhance safety to persons. Examples are: air bag inflators, air bag modules, seat-belt pretensioners and pyromechanical devices. Pyromechanical devices are assembled components for tasks such as but not limited to separation, locking, release-and-drive or occupant restraint. The term includes “Safety devices, pyrotechnic.”
(a) Definitions. An air bag inflator (consisting of a casing containing an igniter, a booster material, a gas generant and, in some cases, a pressure receptacle (cylinder)) is a gas generator used to inflate an air bag in a supplemental restraint system in a motor vehicle. An air bag module is the air bag inflator plus an inflatable bag assembly. A seat-belt pretensioner contains similar hazardous materials and is used in the operation of a seat-belt restraining system in a motor vehicle.
(b) Classification. (1) Safety devices, excluding those which contain flammable or toxic gases or mixtures thereof, may be classed as Class 9 (UN3268) if the safety device, or if more than a single safety device is involved then the representative of the maximum parameters of each design type, is examined and successfully tested by a person or agency who is authorized by the Associate Administrator to perform examination and testing of explosives under § 173.56(b)(1), and who:
(i) Does not manufacture or market explosives or safety devices, is not owned in whole or in part, or is not financially dependent upon any entity that manufactures or markets explosives or safety devices;
(ii) Performs all examination and testing in accordance with the applicable requirements as specified in special provision 160 (see § 172.102 of this subchapter); and
(iii) Maintains records in accordance with paragraph (g) of this section.
(iv) By adhering to all the provisions specified in paragraph (b)(1) of this section, a Class 9 (UN3268) air bag inflator, air bag module or seat-belt pretensioner design is not required to be submitted to the Associate Administrator for approval or assigned an EX number. All other Class 9 (UN3268) safety device designs are required to be submitted to the Associate Administrator for approval and assigned an EX number;
(2) A safety device may be classed as Division 1.4G if the maximum parameters of each design type have been examined and successfully tested by a person or agency who is authorized by the Associate Administrator to perform such examination and testing of explosives under § 173.56(b)(1). As a Class 1 explosive, the manufacturer must submit to the Associate Administrator a report of the examination and assignment of a recommended shipping description, division, and compatibility group, and if the Associate Administrator finds the approval request meets the regulatory criteria, the explosive may be approved in writing and assigned an EX number; or
(3) The manufacturer has submitted an application, including a classification issued by the competent authority of a foreign government to the Associate Administrator, and received written notification from the Associate Administrator that the device has been approved for transportation and assigned an EX number.
(c) EX numbers. (1) When a safety device is classed and approved as a Division 1.4G and offered for transportation, the shipping paper must contain the EX number or product code for each approved device in association with the basic description required by § 172.202(a) of this subchapter. Product codes must be traceable to the specific EX number assigned to the device by the Associate Administrator. Further, if the EX number or product code is contained on the shipping paper then it is not required to be marked on the outside package.
(2) A safety device, when classed as a Class 9 (UN3268), is excepted from the EX number, or product code shipping paper requirements of paragraph (c) of this section.

§ 173.225 Packaging requirements and other provisions for organic peroxides.
(a) General. When the § 172.101 table specifies that an organic peroxide must be packaged under this section, the organic peroxide must be packaged and offered for transportation in accordance with the provisions of this section. Each packaging must conform to the general requirements of subpart B of part 173 and to the applicable requirements of part 178 of this subchapter. Non-bulk packagings must meet Packing Group II performance levels. To avoid unnecessary confinement, metallic non-bulk packagings meeting Packing Group I are not authorized. No used material, other than production residues or regrind from the same production process, may be used in plastic packagings. Organic peroxides that require temperature control are subject to the provisions of § 173.21(f). When an IBC or bulk packaging is authorized and meets the requirements of paragraph (f) or (h) of this section, respectively, lower control temperatures than those specified for non-bulk packaging may be required. An organic peroxide not identified in paragraph (c), (e), or (g) of this section by technical name, or not assigned to a generic type in accordance with the provisions in paragraph (b)(3) of this section, must conform to the provisions of paragraph (c) of § 173.128.
(b) New organic peroxides, formulations and samples. (1) Except as provided for samples in paragraph (b)(2) of this section, no person may offer for transportation an organic peroxide that is not identified by technical name in the Organic Peroxides Table, Organic Peroxide IBC Table, or the Organic Peroxide Portable Tank Table of this section, or a formulation of one or more organic peroxides that are identified by technical name in one of those tables, unless the organic peroxide is assigned a generic type and shipping description and is approved by the Associate Administrator under the provisions of § 173.128(d) of this subchapter.
(2) Samples. Samples of new organic peroxides or new formulations of organic peroxides identified in the Organic Peroxides Table in paragraph (c) of this section, for which complete test data are not available, and that are to be transported for further testing or product evaluation, may be assigned an appropriate shipping description for organic peroxide Type C, packaged and offered for transportation, under the following conditions:
(i) Data available to the person offering the material for transportation must indicate that the sample would pose a level of hazard no greater than that of an organic peroxide Type B and that the control temperature, if any, is sufficiently low to prevent any dangerous decomposition and sufficiently high to prevent any dangerous phase separation;
(ii) The sample must be packaged in accordance with packing method OP2, for a liquid or solid, respectively;
(iii) Packages of the organic peroxide may be offered for transportation and transported in a quantity not to exceed 10 kg (22 pounds) per transport vehicle; and
(iv) One of the following shipping descriptions must be assigned:
(A) Organic peroxide Type C, liquid, 5.2, UN 3103;
(B) Organic peroxide Type C, solid, 5.2, UN 3104;
(C) Organic peroxide Type C, liquid, temperature controlled, 5.2, UN 3113; or
(D) Organic peroxide Type C, solid, temperature controlled, 5.2, UN 3114.
(3) Mixtures. Mixtures of organic peroxides individually identified in the Organic Peroxides Table in paragraph (c) of this section may be classified as the same type of organic peroxide as that of the most dangerous component and be transported under the conditions for transportation given for this type. If the stable components form a thermally less stable mixture, the SADT of the mixture must be determined and the new control and emergency temperature derived under the provisions of § 173.21(f).
(c) Organic peroxides table. The following Organic Peroxides Table specifies by technical name those organic peroxides that are authorized for transportation and not subject to the approval provisions of § 173.128 of this part. An organic peroxide identified by technical name in the following table is authorized for transportation only if it conforms to all applicable provisions of the table. The column headings of the Organic Peroxides Table are as follows:
(1) Technical name. The first column specifies the technical name.
(2) ID number. The second column specifies the identification (ID) number which is used to identify the proper shipping name in the § 172.101 table. The word “EXEMPT” appearing in the column denotes that the material is not regulated as an organic peroxide.
(3) Concentration of organic peroxide. The third column specifies concentration (mass percent) limitations, if any, in mixtures or solutions for the organic peroxide. Limitations are given as minimums, maximums, or a range, as appropriate. A range includes the lower and upper limits (i.e., “53-100” means from, and including, 53% to, and including 100%). See introductory paragraph of § 172.203(k) of this subchapter for additional description requirements for an organic peroxide that may qualify for more than one generic listing, depending on its concentration.
(4) Concentration of diluents. The fourth column specifies the type and concentration (mass percent) of diluent or inert solid, when required. Other types and concentrations of diluents may be used if approved by the Associate Administrator.
(i) The required mass percent of “Diluent type A” is specified in column 4a. A diluent type A is an organic liquid that does not detrimentally affect the thermal stability or increase the hazard of the organic peroxide and with a boiling point not less than 150 °C at atmospheric pressure. Type A diluents may be used for desensitizing all organic peroxides.
(ii) The required mass percent of “Diluent type B” is specified in column 4b. A diluent type B is an organic liquid which is compatible with the organic peroxide and which has a boiling point, at atmospheric pressure, of less than 150 °C (302 °F) but at least 60 °C (140 °F), and a flash point greater than 5 °C (41 °F). Type B diluents may be used for desensitizing all organic peroxides, when specified in the organic peroxide tables, provided that the boiling point is at least 60 °C (140 °F) above the SADT of the peroxide in a 50 kg (110 lbs) package. A type A diluent may be used to replace a type B diluent in equal concentration.
(iii) The required mass percent of “Inert solid” is specified in column 4c. An inert solid is a solid that does not detrimentally affect the thermal stability or hazard of the organic peroxide.
(5) Concentration of water. Column 5 specifies, in mass percent, the minimum amount of water, if any, which must be in formulation.
(6) Packing method. Column 6 specifies the highest packing method (largest packaging capacity) authorized for the organic peroxide. Lower numbered packing methods (smaller packaging capacities) are also authorized. For example, if OP3 is specified, then OP2 and OP1 are also authorized. The Table of Packing Methods in paragraph (d) of this section defines the non-bulk packing methods.
(7) Temperatures. Column 7a specifies the control temperature. Column 7b specifies the emergency temperature. Temperatures are specified only when temperature controls are required. (See § 173.21(f)).
(8) Notes. Column 8 specifies other applicable provisions, as set forth in notes following the table.

(h) Bulk packagings other than IBCs. The following bulk packagings are authorized, subject to the conditions and limitations of this section, if the organic peroxide is listed in the Organic Peroxide Portable Tank Table and bulk packagings are authorized, or if the organic peroxide is specifically authorized for transport in a bulk packaging by this paragraph (h), and the bulk packaging conforms to the requirements of this subchapter:
(1) Rail cars. Class DOT 103, 104, 105, 109, 111, 112, 114, 115, or 120 fusion-weld tank car tanks are authorized. DOT 103W, 111A60F1 and 111A60W1 tank car tanks must have bottom outlets effectively sealed from inside. Gauging devices are required on DOT 103W tank car tanks. Riveted tank car tanks are not authorized.
(2) Cargo tanks. Specification MC 307, MC 310, MC 311, MC 312, DOT 407, and DOT 412 cargo tank motor vehicles with a tank design pressure of at least 172 kPa (25 psig) are authorized.
(3) Portable tanks. The following requirements apply to portable tanks intended for the transport of organic peroxides or self-reactive substances. DOT 51, 57, IM 101 portable tanks, and UN portable tanks that conform to the requirements of paragraph (g) of this section, are authorized. Type F organic peroxide or self-reactive substance formulations other than those indicated in the Organic Peroxide Portable Tank Table may be transported in portable tanks if approved by the Associate Administrator. The following conditions also apply:
(i) The portable tank must be designed for a test pressure of at least 0.4 MPa (4 bar).
(ii) The portable tank must be fitted with temperature-sensing devices.
(iii) The portable tank must be fitted with pressure relief devices and emergency-relief devices. Vacuum-relief devices may also be used. Pressure relief devices must operate at pressures determined according to both the properties of the hazardous material and the construction characteristics of the portable tank. Fusible elements are not allowed in the shell.
(iv) The pressure relief devices must consist of reclosing devices fitted to prevent significant build-up within the portable tank of the decomposition products and vapors released at a temperature of 50 °C (122 °F). The capacity and start-to-discharge pressure of the relief devices must be in accordance with the applicable requirements of this subchapter specified for the portable tank. The pressure relief devices must not allow liquid to escape in the event the portable tank is overturned in a loaded condition.
(v)(A) The emergency-relief devices may be of the reclosing or frangible types, or a combination of the two, designed to vent all the decomposition products and vapors evolved during a period of not less than one hour of complete fire engulfment as calculated by the following formula:
(B) Insulation factor (F) in the formula in paragraph (h)(3)(v)(A) of this section equals 1 for non-insulated vessels and for insulated vessels F is calculated using the following formula:
(vi) The start-to-discharge pressure of emergency-relief devices must be higher than that specified for the pressure relief devices in paragraph (h)(3)(iv) of this section. The emergency-relief devices must be sized and designed in such a way that the maximum pressure in the shell never exceeds the test pressure of the portable tank.
An example of a method to determine the size of emergency-relief devices is given in Appendix 5 of the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter). A second example of a test method for venting sizing is given in the American Institute of Chemical Engineers Process Safety Progress Journal, June 2002 issue (Vol. 21, No. 2) (Informational materials not requiring incorporation by reference, see § 171.7(b)).
(vii) For insulated portable tanks, the capacity and setting of emergency-relief devices must be determined assuming a loss of insulation from 1% of the surface area.
(viii) Vacuum-relief devices and reclosing devices on portable tanks used for flammable hazardous materials must be provided with flame arresters. Any reduction of the relief capacity caused by the flame arrester must be taken into account and the appropriate relief capacity must be provided.
(ix) Service equipment such as devices and external piping must be designed and constructed so that no hazardous material remains in them after filling the portable tank.
(x) Portable tanks may be either insulated or protected by a sun-shield. If the SADT of the hazardous material in the portable tank is 55 °C (131 °F) or less, the portable tank must be completely insulated. The outer surface must be finished in white or bright metal.
(xi) The degree of filling must not exceed 90% at 15 °C (59 °F).
(xii) DOT 57 metal portable tanks are authorized only for those materials or mixtures of two or more materials that are provided with a reference to Note 9 in Column 8 of the Organic Peroxide Table, found in paragraph (c) of this section. DOT 57 portable tanks must conform to the venting requirements of paragraph (f) of this section. These portable tanks are not subject to any other requirements of paragraph (h) of this section.
(4) For tertiary butyl hydroperoxide (TBHP), each tank car, cargo tank or portable tank must contain 7.6 cm (3.0 inches) low density polyethylene (PE) saddles having a melt index of at least 0.2 grams per 10 minutes (for example see, ASTM D1238, condition E) as part of the lading, with a ratio of PE to TBHP over a range of 0.008 to 0.012 by mass. Alternatively, plastic or metal containers equipped with fusible plugs having a melting point between 69 °C (156 °F) and 71 °C (160 °F) and filled with a sufficient quantity of water to dilute the TBHP to 65% or less by mass may be used. The PE saddles must be visually inspected after each trip and, at a minimum, once every 12 months, and replaced when discoloration, fracture, severe deformation, or other indication of change is noted.

Leakage must be determined using a soap bubble solution or other equivalent means on all possible leak locations, when the fuel cell cartridge is charged to its rated charging pressure. The fuel cell cartridge must then be hydrostatically pressurized to destruction. The burst pressure must be greater than 85% of the minimum shell burst pressure. The drop must be performed in the following four different orientations:
(A) Vertically, on the end containing the shut-off valve assembly;
(B) Vertically, on the end opposite to the shut-off valve assembly;
(C) Horizontally, onto a steel apex with a diameter of 3.8 cm (9.7 in), with the steel apex in the upward position; and
(D) At a 45° angle on the end containing the shut-off valve assembly.
(ii) Fire test. A fuel cell cartridge filled to rated capacity (with hydrogen) must be subjected to a fire engulfment test. The cartridge design (including design types with an integral vent feature) is deemed to pass the fire test if:
(A) The internal pressure vents to zero gauge pressure without the rupture of the cartridge; or
(B) The cartridge withstands the fire for a minimum of 20 minutes without rupture.
(iii) Hydrogen cycling test. A fuel cell cartridge must be subjected to a hydrogen cycling test to ensure that the design stress limits are not exceeded during use. The fuel cell cartridge must be cycled from not more than 5% rated hydrogen capacity to not less than 95% rated hydrogen capacity and back to not more than 5% rated hydrogen capacity. The rated charging pressure must be used for charging and temperatures must be within the operating temperature range. The cycling must be continued for at least 100 cycles. Following the cycling test the fuel cell cartridge must be charged and the water volume displaced by the cartridge must be measured. The cartridge design is deemed to pass the test if the water volume displaced by the cycled cartridge does not exceed the water volume displaced by an uncycled cartridge charged to 95% rated capacity and pressurized to 75% of its minimum shell burst pressure.
(6) Production leak test. Each fuel cell cartridge must be tested for leaks at 15 °C ±5 °C (59 °F ±9 °F) while pressurized to its rated charging pressure. There must be no leakage. Leakage must be determined using a soap bubble solution or other equivalent means on all possible leak locations.

(3) Liquefied petroleum gas must be shipped in specification cylinders as follows:
(i) DOT 3, 3A, 3AA, 3B, 3E, 3AL, 4B, 4BA, 4B240ET, 4BW, 4E, or 39 cylinders. The internal volume of a Specification 39 cylinder must not exceed 75 cubic inches. Shipments of flammable gases in DOT 3AL cylinders are authorized only when transported by motor vehicle, rail car, or cargo-only aircraft.
(ii) Additional containers may be used within the limits of quantity and pressure as follows:
| Type of container | Maximum capacity (cubic inches) | Maximum filling pressure (psig) |
|---|---|---|
| DOT-2P or DOT-2Q (see Note 1) | 31.83 | 45 psig at 70 °F and 105 psig at 130 °F (see Note 2). |
| DOT-2P or DOT-2Q (see Note 1) | 31.83 | 35 psig at 70 °F and 100 psig at 130 °F. |
(4) Verification of content. A cylinder with a water capacity of 90.72 kg (200 lb) or more and for use with a liquefied petroleum gas with a specific gravity of 0.504 or greater at 16 °C (60 °F) may have the quantity of its contents determined by using a fixed length dip tube gauging device. The length of the dip tube must be such that when a liquefied petroleum gas, with a specific volume of 0.03051 cu. ft./lb. at a temperature of 40 °F, is filled into the container, the liquid just reaches the bottom of the tube. The weight of this liquid may not exceed 42 percent of the water capacity of the container, which must be stamped on the cylinder. The length of the dip tube, expressed in inches carried out to one decimal place and prefixed with the letters “DT”, must be stamped on the container and on the exterior of removable type dip tube. For the purpose of this requirement, the marked length must be expressed as the distance measured along the axis of a straight tube from the top of the boss through which the tube is inserted to the proper level of the liquid in the container. The length of each dip tube must be checked when installed by weighing each container after filling except when installed in groups of substantially identical containers, in which case one of each 25 containers must be weighed. The quantity of liquefied gas in each container must be checked by means of the dip tube after disconnecting from the filling line. The outlet from the dip tube may not be larger than 0.1016 centimeters (0.040 inch; No. 54 drill bit size orifice). A container representative of each day’s filling at each filling plant must have its contents checked by weighing after disconnecting from the filling line.
(e) Carbon dioxide, refrigerated liquid or nitrous oxide, refrigerated liquid. (1) The following provisions apply to carbon dioxide, refrigerated liquid, and nitrous oxide, refrigerated liquid:
(i) DOT 4L cylinders conforming to the provisions of this paragraph are authorized.
(ii) Each cylinder must be protected with at least one pressure relief device and at least one frangible disc conforming to § 173.301(f) and paragraph (a)(2) of this section. The relieving capacity of the pressure relief device system must be equal to or greater than that calculated by the applicable formula in paragraph 5.8.3 of CGA S-1.1 (IBR, see § 171.7 of this subchapter).
(iii) The temperature and pressure of the gas at the time the shipment is offered for transportation may not exceed −18 °C (0 °F) and 290 psig for carbon dioxide and −15.6 °C (+4 °F) and 290 psig for nitrous oxide. Maximum time in transit may not exceed 120 hours.
(2) The following pressure relief device settings, design service temperatures and filling densities apply:
| Pressure relief device setting maximum start – to discharge gauge pressure in psig | Maximum permitted filling density (percent by weight) | |

Compliance with the filling limits may be determined by referencing the numerical values and data in Table 2 of P200 of the UN Recommendations (IBR, see § 171.7 of this subchapter). Alternatively, the maximum allowable filling limits may be determined as follows:
(1) For high pressure liquefied gases, in no case may the filling ratio of the settled pressure at 65 °C (149 °F) exceed the test pressure of the UN pressure receptacle.
(2) For low pressure liquefied gases, the filling factor (maximum mass of contents per liter of water capacity) must be less than or equal to 95 percent of the liquid phase at 50 °C. In addition, the UN pressure receptacle may not be liquid full at 60 °C. The test pressure of the pressure receptacle must be equal to or greater than the vapor pressure of the liquid at 65 °C.
(3) For high pressure liquefied gases or gas mixtures, the maximum filling ratio may be determined using the formulas in (3)(b) of P200 of the UN Recommendations.
(4) For low pressure liquefied gases or gas mixtures, the maximum filling ratio may be determined using the formulas in (3)(c) of P200 of the UN Recommendations.
(5) For liquefied gases charged with compressed gases, both components – the liquefied gas and the compressed gas – must be taken into consideration in the calculation of the internal pressure in the pressure receptacle. The maximum mass of contents per liter of water capacity shall not exceed 95 percent of the density of the liquid phase at 50 °C (122 °F); in addition, the liquid phase shall not completely fill the pressure receptacle at any temperature up to 60 °C (140 °F). When filled, the internal pressure at 65 °C (149 °F) shall not exceed the test pressure of the pressure receptacles. The vapor pressures and volumetric expansions of all substances in the pressure receptacles shall be considered. The maximum filling limits may be determined using the procedure in (3)(e) of P200 of the UN Recommendations.
(c) Tetraflouroethylene, stabilized, UN1081 must be packaged in a pressure receptacle with a minimum test pressure of 200 bar and a working pressure not exceeding 5 bar.
(d) Fertilizer ammoniating solution with free ammonia, UN1043 is not authorized in UN tubes or MEGCs.

(iv) Outer packaging. The containers must be packed in strong outer packagings.
(v) Pressure testing. Except as otherwise provided in this paragraph, each container, after it is filled, must be subjected to a test performed in a hot water bath; the temperature of the bath and the duration of the test must be such that the internal pressure reaches that which would be reached at 55 °C (131 °F), or 50 °C (122 °F) if the liquid phase does not exceed 95% of the capacity of the container at 50 °C (122 °F)). If the contents are sensitive to heat, the temperature of the bath must be set at between 20 °C (68 °F) and 30 °C (86 °F) but, in addition, one container in 2,000 must be tested at the higher temperature. No leakage or permanent deformation of a container may occur. However, instead of this standard water bath test, container(s) may be tested using one of the following methods subject to certain conditions –
(A) Alternative water bath test. (1) One filled container in a lot of 2,000 must be subjected to a test performed in a hot water bath; the temperature of the bath and the duration of the test must be such that the internal pressure reaches that which would be reached at 55 °C (131 °F). If the container shows evidence of leakage or permanent deformation, the lot of 2,000 containers must be rejected;
(2) A second filled container in the lot of 2,000 must be weighed and compared to the weight specification for the containers as documented in the operating procedures for the weight test. Failure of the container to meet the weight specification is evidence of leakage or overfilling and the lot of 2,000 must be rejected;
(3) The remainder of the containers in the lot of 2,000 must be visually inspected (e.g, examination of the seams). Containers showing evidence of leakage or overfilling must not be transported; and
(4) Each person employing this test must maintain a copy of the operating procedures (or an electronic file thereof) that is accessible at, or through, its principal place of business and must make the procedures available upon request, at a reasonable time and location, to an authorized official of the Department.
(B) Automated pressure test. Each person employing an automated process for pressure testing of filled containers must develop procedures for implementation of the test. Each person must maintain a copy of the procedures (or an electronic file thereof) that is accessible at, or through, its principal place of business and must make the procedures available upon request, at a reasonable time and location, to an authorized official of the Department. The procedures must, at a minimum, include instruction on the following:
(1) Pressure specifications. Each person must specify pressure standard(s) (e.g., a pressure limit or range) for a container respective of the design and/or contents. Each container, after it is filled, must be pressure checked and compared to the standards. For a pressure limit, any container exceeding the pressure limit must be rejected. For a pressure range, any container outside of the set range must be rejected. The instruments used to determine the pressure must be properly calibrated before a production run to an accuracy of ±or better; and
(2) Periodic inspection. At designated intervals, a randomly selected container must be inspected for proper closure and verification of filling pressure. If a container shows signs of improper closure or over-filling, five (5) additional randomly selected containers must be inspected. If any of the additional containers show signs of improper closure or over-filling, all containers produced since the last inspection must be rejected.
(C) Weight test. Each person employing a weight test of filled containers must develop procedures for implementation of the test. Each person must maintain a copy of the procedures (or an electronic file thereof) that is accessible at, or through, its principal place of business and must make the procedures available upon request, at a reasonable time and location, to an authorized official of the Department. The procedures must, at a minimum, include instruction on the following:
(1) Weight specifications. Each person must specify target weight specifications for a particular container. Each container, after it is filled, must be weighed and compared to the target weight specification for the container. Any container outside the target weight specification is an indication of leakage or overfilling and must be rejected. The instruments used to determine the weight must be properly calibrated before a testing run and be sufficiently sensitive to measure within 0.10 g of the true weight of the container;
(2) Heat testing and pressure limits. One container out of each lot of successfully filled containers must be heat tested by raising the internal pressure until it reaches that which would be reached at 55 °C (131 °F). The lot size should be no greater than 2,000. If the pressure in the container exceeds the maximum pressure allowed for the container type or if the container shows signs of leakage or permanent deformation, the lot must be rejected. Alternatively, five (5) additional randomly selected containers from the lot may be tested to qualify the lot but if any of the five containers fail the test, the entire lot must be rejected;
(3) Periodic inspection. At intervals of not more than 10 minutes, a randomly selected container must be inspected for proper closure and verification of filling pressure. If a container shows signs of improper closure or over-filling, five (5) additional randomly selected containers must be inspected. If any of the additional containers show signs of improper closure or over-filling, all containers produced since the last inspection must be rejected; and
(4) Visual inspection. Each container must be visually inspected prior to being packed. Any container showing signs of leakage or permanent deformation must be rejected.
(D) Leakage test. (1) Pressure and leak testing before filling. Each empty container must be subjected to a pressure equal to or in excess of the maximum expected in the filled containers at 55 °C (131 °F) or 50 °C (122 °F) if the liquid phase does not exceed 95% of the capacity of the container at 50 °C (122 °F). This must be at least two-thirds of the design pressure of the container. If any container shows evidence of leakage at a rate equal to or greater than 3.3 × 10
(2) Testing after filling. The person filling each container must ensure that the crimping equipment is set appropriately and the specified propellant is used before filling a container. Once filled, each container must be weighed and leak tested. The leak detection equipment must be sufficiently sensitive to detect at least a leak rate of 2.0 × 10
(vi) Each outer packaging must be marked “INSIDE CONTAINERS COMPLY WITH PRESCRIBED REGULATIONS.”
(4) Gas samples must be transported under the following conditions:

If the contents are sensitive to heat, or if the container is made of plastic material which softens at this test temperature, the temperature of the bath must be set at between 20 °C (68 °F) and 30 °C (86 °F) but, in addition, one container in 2,000 must be tested at the higher temperature. No leakage or permanent deformation of a container is permitted except that a plastic container may be deformed through softening provided that it does not leak.
(vi) Leakage test. As an alternative to the hot water bath test in paragraph (a)(5)(v) of this section, testing may be performed as follows:
(A) Pressure and leak testing before filling. Each empty container must be subjected to a pressure equal to or in excess of the maximum expected in the filled containers at 55 °C (131 °F) or 50 °C (122 °F) if the liquid phase does not exceed 95% of the capacity of the container at 50 °C (122 °F).

However, this restriction does not preclude transportation of pressure receptacles filled and offered for transportation prior to the requalification due date.
(5) Prior to filling and offering a MEGC for transportation, the MEGC’s structural and service equipment must be visually inspected. Any unsafe condition must be corrected before the MEGC is offered for transportation. All required markings must be legible.
(6) Except for Division 2.2 permanent gases, each pressure receptacle must be equipped with an individual shutoff valve that must be tightly closed while in transit. For Division 2.1, Division 2.2 liquefied gases and 2.3 gases, the manifold must be designed so that each pressure receptacle can be filled separately and be kept isolated by a valve capable of being closed during transit. For Division 2.1 gases, the pressure receptacles must be isolated by a valve into assemblies of not more than 3,000 L.
(b) Filling. (1) A MEGC may not be filled above its marked maximum permissible gross mass. Additionally, MEGCs must be filled in accordance with the following:
(i) A MEGC being filled with non-liquefied (permanent) compressed gas may not be filled to a pressure greater than the lowest marked working pressure of any cylinder (pressure receptacle).
(ii) An MEGC being filled with a liquefied compressed gas must have each pressure receptacle filled separately by weight and must be filled by a means to ensure that only one pressure receptacle is filled at a time.
(iii) The filling density for UN pressure receptacles may not exceed the values in accordance with § 173.304b(b).
(2) After each filling, the shipper must verify the leakproofness of the closures and equipment. Each fill opening must be closed by a cap or plug.
(c) Damage protection. During transportation, a MEGC must be protected against damage to the pressure receptacles and service equipment resulting from lateral and longitudinal impact and overturning as prescribed in § 178.75 of this subchapter.
§ 173.313 UN Portable Tank Table for Liquefied Compressed Gases and Chemical Under Pressure.
The UN Portable Tank Table for Liquefied Compressed Gases and chemical under pressure is referenced in § 172.102(c)(7)(iii) of this subchapter for portable tanks that are used to transport liquefied compressed gases and chemicals under pressure. The table applies to each liquefied compressed gas and chemical under pressure that are identified with Special Provision T50 in Column (7) of the § 172.101 Hazardous Materials Table. In addition to providing the UN identification number and proper shipping name, the table provides maximum allowable working pressures, bottom opening requirements, pressure relief device requirements, and degree of filling requirements for liquefied compressed gas and chemical under pressure permitted for transportation in a T50 portable tank. In the minimum test pressure column, “small” means a portable tank with a diameter of 1.5 meters or less when measured at the widest part of the shell, “sunshield” means a portable tank with a shield covering at least the upper third of the shell, “bare” means no sunshield or insulation is provided, and “insulated” means a complete cladding of sufficient thickness of insulating material necessary to provide a minimum conductance of not more than 0.67 w/m

§ 173.314 Compressed gases in tank cars and multi-unit tank cars.
(a) Definitions. For definitions of compressed gases, see § 173.115.
(b) General requirements. (1) Tank car tanks containing compressed gases must not be shipped unless they were loaded by or with the consent of the owner thereof.
(2) Tank car tanks must not contain gases capable of combining chemically and must not be loaded with any gas which combines chemically with the gas previously loaded therein, until all residue has been removed and interior of tank thoroughly cleaned.
(3) For tanks of the DOT-106A and 110A class, the tanks must be placed in position and attached to car structure by the shipper.
(4) Wherever the word “approved” is used in this part of the regulations, it means approval by the Association of American Railroads Committee on Tank Cars as prescribed in § 179.3 of this subchapter.
(5) Each tank car used for the transportation of anhydrous ammonia or any material that meets the criteria of Division 2.1 or 2.3 must have gaskets for manway cover plates and for mounting of fittings designed (for temperature, application, media, pressure, and size) to create a positive seal so that, under conditions normally incident to transportation, there will not be an identifiable release of the material to the environment. The use of sealants to install gaskets is prohibited.
(c) Authorized gases, filling limits for tank cars. A compressed gas in a tank car or a multi-unit tank car must be offered for transportation in accordance with § 173.31 and this section. The gases listed below must be loaded and offered for transportation in accordance with the following table:

(1) Odorization. All liquefied petroleum gas must be odorized as required in this paragraph to indicate positively, by a distinctive odor, the presence of gas down to a concentration in air of not over one-fifth the lower limit of combustibility; however, odorization is not required if it is harmful in the use or further processing of the liquefied petroleum gas or if it will serve no useful purpose as a warning agent in such use or further processing.
(i) The lower limits of combustibility of the more commonly used liquefied petroleum gases are: Propane, 2.15 percent; butane, 1.55 percent. These figures represent volumetric percentages of gas-air mixtures in each case.
(ii) The use of 1.0 pound of ethyl mercaptan per 10,000 gallons of liquefied petroleum gas is considered sufficient to meet the requirements of this paragraph (b). Use of any other odorant is not prohibited so long as there is enough to meet the requirements of this paragraph.
(2) Odorant fade. For cargo tanks or portable tanks being transported from a refinery, gas plant or pipeline terminal and in addition to paragraph (b)(1)(i) of this section, the offeror must ensure that enough odorant will remain in the cargo tank or portable tank during the course of transportation. The offeror must have procedures in place to:
(i) Ensure quantitative testing methods are used to measure the amount of odorant in the liquefied petroleum gas;
(ii) Ensure that, when the odorization of liquefied petroleum gas is manually injected, the required amount of odorant is being added;
(iii) Ensure that, when odorization of liquefied petroleum gas is automatically injected, equipment calibration checks are conducted to ensure the required amount of odorant is consistently added;
(iv) Ensure that quality control measures are in place to make sure that persons who receive cargo tanks or portable tanks that have been subjected to any condition that could lead to corrosion of the packaging or receive new or recently cleaned cargo tanks or portable tanks are notified of this information and that a person filling these packagings implement quality control measures to ensure that potential odorant fade is addressed;
(v) Inspect a cargo tank or portable tank for signs of oxidation or corrosion; and
(vi) Take corrective action needed to ensure enough odorant remains in the cargo tank or portable tank during the course of transportation, such as increasing the amount of odorant added to the liquefied petroleum gas.
(c) Except as otherwise provided, the loading of a liquefied gas into a cargo tank or portable tank shall be determined by weight or by a suitable liquid level gauging device. The vapor pressure (psig) at 115 °F. must not exceed the design pressure of the cargo tank or portable tank container. The outage and filling limits for liquefied gases must be as prescribed in § 173.24b of this part, except that this requirement does not apply to:
(1) A tank containing carbon dioxide, refrigerated liquid or nitrous oxide, refrigerated liquid. Such tank is required to be equipped with suitable pressure control valves and may not be filled to a level exceeding 95 percent of the volumetric capacity of the tank.
(2) A tank containing ethane, refrigerated liquid; ethane-propane mixture, refrigerated liquid; or hydrogen chloride, refrigerated liquid. Such tank must be filled to allow at least two percent outage below the inlet of the pressure relief valve or pressure control valve under conditions of incipient opening, with the tank in a level attitude.
(d) If the loading of cargo tanks and portable tank containers with liquefied gases is to be determined by weight, the gross weight shall be checked after the filling line is disconnected in each instance. The gross weight shall be calculated from the tank capacity and tare weight set forth on the metal plate required by the specification, and the maximum filling density permitted for the material being loaded into the tank as set forth in the table, paragraph (a) of this section.
(e) If the loading of cargo tanks and portable tank containers with liquefied gases is to be determined by adjustable liquid level device, each tank and each compartment thereof shall have a thermometer well, so that the internal liquid temperature can easily be determined, and the amount of liquid in the tank shall be corrected to a 60 °F. basis. Liquid levels shall not exceed a level corresponding to the maximum filling density permitted for the material being loaded into the tank as set forth in the table in paragraph (a) of this section.
(f) When the loading of cargo tanks and portable tank containers with liquefied gases is determined only by fixed length dip tube or other fixed maximum liquid level indicator, the device shall be arranged to function at a level not to exceed the maximum permitted volume prescribed by the table, paragraph (a) of this section. Loading shall be stopped when the device functions.
(g) Containers, the liquid level of which has been determined by means of a fixed length dip tube gauging device, shall not be acceptable for stowage as cargo on vessels in commerce subject to the jurisdiction of the United States Coast Guard. Nothing contained in this section shall be so construed as to prohibit the transportation on car floats or car ferries of motor vehicles laden with containers nor cargo tanks the liquid level of either of which has been determined by means of fixed length dip tube devices.

(4) Mixtures of cryogenic liquid. Where charging requirements are not specifically prescribed in this paragraph (f), the cryogenic liquid must be shipped in packagings and under conditions approved by the Associate Administrator.
(g) One-way travel time; marking. The jacket of a cargo tank to be used to transport a flammable cryogenic liquid must be marked on its right side near the front, in letters and numbers at least two inches high, “One-Way-Travel-Time __ hrs.”, with the blank filled in with a number indicating the one-way travel time (OWTT), in hours, of the cargo tank for the flammable cryogenic liquid to be transported. A cargo tank that is partially unloaded at one or more locations must have additional marking “One-Way-Travel-Time __ hrs. __ psig to __ psig at __ percent filling density,” with the second blank filled in with the pressure existing after partial unloading and the third blank filled in with the set-to-discharge pressure of the control valve or pressure relief valve, and the fourth blank with the filling density following partial unloading. Multiple OWTT markings for different pressure levels are permitted. The abbreviation “OWTT” may be used in place of the words “One-way-travel-time” in the marking required by this paragraph.
(1) OWTT is based on the marked rated holding time (MRHT) of the cargo tank for the cryogenic liquid to be transported in the cargo tank. If the MRHT for the flammable cryogenic liquid is not displayed on or adjacent to the specification plate, this MRHT may be derived.
(2) The MRHT is converted to OWTT, in hours, as follows:
(i) For a tank with an MRHT of 72 hours or less,
(ii) For a tank with an MRHT greater than 72 hours,
(3) Each cargo tank motor vehicle used to transport a flammable cryogenic liquid must be examined after each shipment to determine its actual holding time. The record required by § 177.840(h) of this subchapter may be used for this determination. If the examination indicates that the actual holding time of the cargo tank, after adjustment to reflect an average ambient temperature of 85 °F, is less than 90 percent of the marked rated holding time (MRHT) for the cryogenic liquid marked on the specification plate or adjacent thereto (see § 178.338-18(b) of this subchapter), the tank may not be refilled with any flammable cryogenic liquid until it is restored to its marked rated holding time value or it is re-marked with the actual marked rated holding time determined by this examination. If the name of the flammable cryogenic liquid that was transported and its marked rated holding time is not displayed on or adjacent to the specification plate, this requirement may be met by deriving the MRHT of the cargo tank for that flammable cryogenic liquid and comparing that derived MRHT with the actual holding time after adjustment.

(1) Excluding the interior surfaces of the containment system of packages and the internal surfaces of a conveyance, freight container, tank, or intermediate bulk container dedicated to the transport of unpackaged radioactive material in accordance with § 173.427(c) and remaining under that specific exclusive use, the level of non-fixed contamination may not exceed the limits set forth in Table 9 and must be determined by either:
(i) Wiping an area of 300 cm
(ii) Alternatively, the level of non-fixed contamination may be determined by using other methods of equal or greater efficiency.
(2) A conveyance used for non-exclusive use shipments is not required to be surveyed unless there is reason to suspect that it may exhibit contamination.
Table 9 is as follows:
Table 9 – Non-Fixed External Radioactive Contamination Limits for Packages
2 | 2 | 2 | |
|---|---|---|---|
| 1. Beta and gamma emitters and low toxicity alpha emitters | 4 | 10 | 240 |
| 2. All other alpha emitting radionuclides | 0.4 | 10 | 24 |
(b) In the case of packages transported as exclusive use shipments by rail or public highway only, except as provided in paragraph (d) of this section, at any time during transport the non-fixed contamination on the external surface of any package, as well as on the associated accessible internal surfaces of any conveyance, overpack, or freight container, may not exceed ten times the levels prescribed in paragraph (a) of this section. The levels at the beginning of transport may not exceed the levels prescribed in paragraph (a) of this section.
(c) Except as provided in paragraphs (a) and (d) of this section, each conveyance, overpack, freight container, tank, or intermediate bulk container used for transporting Class 7 (radioactive) materials as an exclusive use shipment that utilizes the provisions of paragraph (b) of this section, § 173.427(b)(4), or § 173.427(c) must be surveyed with appropriate radiation detection instruments after each exclusive use transport. Except as provided in paragraphs (a) and (d) of this section, these items may not be returned to Class 7 (radioactive) materials exclusive use transport service, and then only for a subsequent exclusive use shipment utilizing one of the above cited provisions, unless the radiation dose rate at each accessible surface is 0.005 mSv per hour (0.5 mrem per hour) or less, and there is no significant non-fixed surface contamination as specified in paragraph (a) of this section. The requirements of this paragraph do not address return to service of items outside of the above cited provisions.
(d) Paragraphs (b) and (c) of this section do not apply to any closed transport vehicle used solely for the exclusive use transportation by highway or rail of Class 7 (radioactive) material with contamination levels that do not exceed ten times the levels prescribed in paragraph (a) of this section if –
(1) A survey of the interior surfaces of the empty vehicle shows that the radiation dose rate at any point does not exceed 0.1 mSv/h (10 mrem/h) at the surface or 0.02 mSv/h (2 mrem/h) at 1 m (3.3 feet) from the surface;
(2) Each vehicle is marked (e.g. stenciled) with the words “For Radioactive Materials Use Only” in letters at least 76 millimeters (3 inches) high in a conspicuous place on both sides of the exterior of the vehicle; and
(3) Each vehicle is kept closed except for loading or unloading; and
(4) Each vehicle is placarded in accordance with subpart F of part 172 of this subchapter.
(e) If it is evident that a package of radioactive material, or conveyance carrying unpackaged radioactive material, is leaking, or if it is suspected that the package, or conveyance carrying unpackaged material, may have leaked, access to the package or conveyance must be restricted and, as soon as possible, the extent of contamination and the resultant radiation level of the package or conveyance must be assessed. The scope of the assessment must include, as applicable, the package, the conveyance, the adjacent loading and unloading areas, and, if necessary, all other material which has been carried in the conveyance. When necessary, additional steps for the protection of persons, property, and the environment must be taken to overcome and minimize the consequences of such leakage. Packages, and conveyances carrying unpackaged material, which are leaking radioactive contents in excess of limits for normal conditions of transport may be removed to an interim location under supervision, but must not be forwarded until repaired or reconditioned and decontaminated, or as approved by the Associate Administrator.

§ 173.461 Demonstration of compliance with tests.
(a) Compliance with the design requirements in § 173.412 and the test requirements in §§ 173.465 through 173.469 must be shown by any of the methods prescribed in this paragraph, or by a combination of these methods appropriate for the particular feature being evaluated:
(1) Performance of tests with prototypes or samples of the specimens representing LSA-III, special form Class 7 (radioactive) material, or packaging, in which case the contents of the packaging for the test must simulate as closely as practicable the expected range of physical properties of the radioactive contents or packaging to be tested, must be prepared as normally presented for transport. The use of non-radioactive substitute contents is encouraged provided that the results of the testing take into account the radioactive characteristics of the contents for which the package is being tested;
(2) Reference to a previous, satisfactory demonstration of compliance of a sufficiently similar nature;
(3) Performance of tests with models of appropriate scale incorporating those features that are significant with respect to the item under investigation, when engineering experience has shown results of those tests to be suitable for design purposes. When a scale model is used, the need for adjusting certain test parameters, such as the penetrator diameter or the compressive load, must be taken into account; or
(4) Calculations or reasoned evaluation, using reliable and conservative procedures and parameters.
(b) With respect to the initial conditions for the tests under §§ 173.465 through 173.469, except for the water immersion tests, compliance must be based upon the assumption that the package is in equilibrium at an ambient temperature of 38 °C (100 °F).
§ 173.462 Preparation of specimens for testing.
(a) Each specimen (i.e., sample, prototype or scale model) must be examined before testing to identify and record faults or damage, including:
(1) Divergence from the specifications or drawings;
(2) Defects in construction;
(3) Corrosion or other deterioration; and
(4) Distortion of features.
(b) Any deviation found under paragraph (a) of this section from the specified design must be corrected or appropriately taken into account in the subsequent evaluation.
(c) The containment system of the packaging must be clearly specified.
(d) The external features of the specimen must be clearly identified so that reference may be made to any part of it.
§ 173.465 Type A packaging tests.
(a) The packaging, with contents, must be capable of withstanding the water spray, free drop, stacking and penetration tests prescribed in this section. One prototype may be used for all tests if the requirements of paragraph (b) of this section are met. The tests are successful if the requirements of § 173.412(j) are met.
(b) Water spray test. The water spray test must precede each test or test sequence prescribed in this section. The water spray test must simulate exposure to rainfall of approximately 5 cm (2 inches) per hour for at least one hour. The time interval between the end of the water spray test and the beginning of the next test must be such that the water has soaked in to the maximum extent without appreciable drying of the exterior of the specimen. In the absence of evidence to the contrary, this interval may be assumed to be two hours if the water spray is applied from four different directions simultaneously. However, no time interval may elapse if the water spray is applied from each of the four directions consecutively.
(c) Free drop test. The specimen must drop onto the target so as to suffer maximum damage to the safety features being tested, and:
(1) The height of the drop measured from the lowest point of the specimen to the upper surface of the target may not be less than the distance specified in table 10, for the applicable package mass. The target must be as specified in § 173.465(c)(5). Table 10 is as follows:
Table 10 – Free Drop Distance for Testing Packages to Normal Conditions of Transport
| Package mass | Free drop distance | |
|---|---|---|
| Kilograms (pounds) | Meters | (Feet) |
| 1.2 | (4) | |
| 5,000 (11,000) Mass to 10,000 (22,000) | 0.9 | (3) |
| 10,000 (22,000) Mass to 15,000 (33,000) | 0.6 | (2) |

Appendix B to Part 173 – Procedure for Testing Chemical Compatibility and Rate of Permeation in Plastic Packaging and Receptacles
1. The purpose of this procedure is to determine the chemical compatibility and permeability of liquid hazardous materials packaged in plastic packaging and receptacles. Alternatives for this procedure are permitted as specified in § 173.24(e)(3)(iii) of this subchapter.
2. Compatibility and rate of permeation are determined by subjecting full size plastic containers (or smaller containers as permitted in paragraph 4 of this appendix) and hazardous material lading to one of the following combinations of time and temperature:
a. Test Method 1: 180 days at a temperature no lower than 18 °C. (64 °F.)
b. Test Method 2: 28 days at a temperature no lower than 50 °C. (122 °F.)
c. Test Method 3: 14 days at a temperature no lower than 60 °C. (140 °F.)
3. Regardless of which test method is used, at least three sample containers shall be tested for each combination of hazardous material and size and design of container. Fill containers to rated capacity with the specific hazardous material (at the concentration to be transported) and close as for shipment. For the first and last 24 hours of storage under the selected test method, place the containers with closures downward, except that containers fitted with a vent are so placed on each occasion for five minutes only.
4. For testing under Test Method 2 or 3 in those instances where it is not practicable to use full size containers, smaller containers may be used. The small container shall be manufactured by the same process as the larger container (for example, using the same method of molding and processing temperatures) and be made of identical resins, pigments and additives.
5. Determine filled container weight or net weight of contents both before and after storage under the selected test method. Rate of permeation is determined from loss of hazardous materials contents, during the conduct of the test, expressed as a percentage of the original weight.
6. After storage under the selected test method, the container shall be drained, rinsed, filled to rated capacity with water and, with filled container at ambient temperature, dropped from a height determined in accordance with § 178.603(e) of this subchapter onto a rigid non-resilient, flat and horizontal surface.
7. Each of the following constitute test failure:
a. Visible evidence of permanent deformation due to vapor pressure build-up or collapse of walls, deterioration, swelling, crazing, cracking, excessive corrosion, oxidization, embrittlement, leakage, rupture or other defects likely to cause premature failure or a hazardous condition.
b. For materials meeting the definition of a poison according to this subchapter, a rate of permeation in excess of 0.5% determined over the test period. For all other hazardous materials, a rate of permeation in excess of 2.0% determined over the test period.
Appendix C to Part 173 – Procedure for Base-level Vibration Testing
Base-level vibration testing shall be conducted as follows:
1. Three sample packagings, selected at random, must be filled and closed as for shipment. A non-hazardous material may be used in place of the hazardous material if it has essentially the same physical characteristics.
2. The three packages must be placed on a vibrating platform that has a vertical double-amplitude (peak-to-peak displacement) of one inch. The packages should be constrained horizontally to prevent them from falling off the platform, but must be left free to move vertically, bounce and rotate.
3. The test must be performed continuously for one hour at a frequency that causes each package to be raised from the vibrating platform to such a degree that a piece of material of approximately 1.6 mm (0.063 inch) thickness (such as steel strapping or paperboard) can be passed between the bottom of any package and the platform.
4. Immediately following the period of vibration, each package shall be removed from the platform, turned on its side and observed for any evidence of leakage.
5. Rupture or leakage from any of the packages constitutes failure of the test.
Appendix D to Part 173 – Test Methods for Dynamite (Explosive, Blasting, Type A)
A wooden stick, 114 mm (4.5 inches) long and 4.8 mm (0.2 inch) inch in diameter, with a sharpened end is used to punch 5 holes in one end of the wrapper of a dynamite cartridge. A cork stopper is placed on the bottom of a glass volumetric cylinder. The dynamite cartridge is placed, perforated end down, resting on the cork stopper in the cylinder. The entire assembly is placed in an oven at 38 °C (100 °F) for 48 hours and then examined visually for evidence of leakage.
The test apparatus consists of a glass tube, 135 mm (5.3 inches) long and one inch in diameter, with both ends open, and is assembled in the following manner:
(a) Close the bottom with a plastic plug of diameter equal to the inner diameter of the glass tube;
(b) Place a small amount of absorbent cotton on top of the plug;
(c) Place a plastic disk that matches the inner diameter to the glass tube and has seven small perforations on top of the cotton; and
(d) Place 10 g (0.35 ounce) of the dynamite sample on top of the disk.
The entire apparatus for this test is shown in Figure 1 of this appendix. The test is conducted using the following procedures:
(a) A glass tube, 135 mm (5.3 inches) long and one inch in diameter, is held on a wooden base;
(b) A small amount of absorbent cotton is placed into the bottom of the glass tube;
(c) Ten g (0.35 ounce) of dynamite sample are placed on top of the cotton in the glass tube;
(d) A small amount of absorbent cotton is placed on top of the dynamite sample;
(e) A plastic disk that matches the inner diameter of the glass tube and has seven small perforations is placed on top of the cotton;
(f) A plastic plug matching the inner diameter of the glass tube is then placed on top of the disk;
(g) The glass tube assembly is placed under the compression rod, and compression is applied by means of the weight on the metal lever rod. The sample is compressed for one minute; and
(h) The dynamite sample is then removed from the glass tube and weighed to determine the percent of weight loss.

Appendix H to Part 173 – Method of Testing for Sustained Combustibility
The method describes a procedure for determining if the material when heated under the test conditions and exposed to an external source of flame applied in a standard manner sustains combustion.
A metal block with a concave depression (test portion well) is heated to a specified temperature. A specified volume of the material under test is transferred to the well, and its ability to sustain combustion is noted after application and subsequent removal of a standard flame under specified conditions.
A combustibility tester consisting of a block of aluminum alloy or other corrosion-resistant metal of high thermal conductivity is used. The block has a concave well and a pocket drilled to take a thermometer. A small gas jet assembly on a swivel is attached to the block. The handle and gas inlet for the gas jet may be fitted at any convenient angle to the gas jet. A suitable apparatus is shown in Figure 32.5.2.1 of the UN Manual of Test and Criteria (IBR, see (171.7 of this subchapter), and the essential dimensions are given in Figures 32.5.2.1 and 32.5.2.2 of the UN Manual and Tests and Criteria. The following equipment is needed:
(a) Gauge, for checking that the height of the center of the gas jet above the top of the test portion well is 2.2 mm (see Figure 32.5.2.1);
(b) Thermometer, mercury in glass, for horizontal operation, with a sensitivity not less than 1 mm/ °C, or other measuring device of equivalent sensitivity permitting reading at 0.5 °C intervals. When in position in the block, the thermometer bulb must be surrounded with thermally conducting thermoplastic compound;
(c) Hotplate, fitted with a temperature-control device. (Other types of apparatus with suitable temperature-control facilities may be employed to heat the metal block);
(d) Stopwatch, or other suitable timing device;
(e) Syringe, capable of delivering 2 mL to an accuracy of ±0.1 mL; and
(f) Fuel source, butane test fuel.
The sample must be representative of the material to be tested and must be supplied and kept in a tightly closed container prior to test. Because of the possibility of loss of volatile constituents, the sample must receive only the minimum treatment necessary to ensure its homogeneity. After removing each test portion, the sample container must be immediately closed tightly to ensure that no volatile components escape from the container; if this closure is incomplete, an entirely new sample must be taken.
Carry out the determination in triplicate.
(a) It is essential that the apparatus be set up in a completely draft-free area (see warning) and in the absence of strong light to facilitate observation of flash, flame, etc.
(b) Place the metal block on the hotplate or heat the metal block by other suitable means so that its temperature, as indicated by the thermometer placed in the metal block, is maintained at the specified temperature within a tolerance of ±1 °C. For the appropriate test temperature, see paragraph 5.(h) of this appendix. Correct this temperature for the difference in barometric pressure from the standard atmospheric pressure (101.3 kPa) by raising the test temperature for a higher pressure or lowering the test temperature for a lower pressure by 1.0 °C for each 4 kPa difference. Ensure that the top of the metal block is exactly horizontal. Use the gauge to check that the jet is 2.2 mm above the top of the well when in the test position.
(c) Light the butane test fuel with the jet away from the test position (i.e. in the “off” position, away from the well). Adjust the size of the flame so that it is 8 mm to 9 mm high and approximately 5 mm wide.
(d) Using the syringe, take from the sample container at least 2 mL of the sample and rapidly transfer a test portion of 2 mL ±0.1 mL to the well of the combustibility tester and immediately start the timing device.
(e) After a heating time of 60 seconds (s), by which time the test portion is deemed to have reached its equilibrium temperature, and if the test fluid has not ignited, swing the test flame into the test position over the edge of the pool of liquid. Maintain it in this position for 15 s and then return it to the “off” position while observing the behavior of the test portion. The test flame must remain lighted throughout the test.
(f) For each test observe and record:
(i) whether there is ignition and sustained combustion or flashing, or neither, of the test portion before the test flame is moved into the test position;
(ii) whether the test portion ignites while the test flame is in the test position, and, if so, how long combustion is sustained after the test flame is returned to the “off” position.
(g) If sustained combustion interpreted in accordance with paragraph 6. of this appendix is not found, repeat the complete procedure with new test portions, but with a heating time of 30 s.
(h) If sustained combustion interpreted in accordance with paragraph 6. of this appendix is not found at a test temperature of 60 °C (140 °F), repeat the complete procedure with new test portions, but at a test temperature of 75 °C (167 °F). In the case of a material which has a flash point above 60 °C (140 °F) and below 93 °C (200 °F), if sustained combustion interpreted in accordance with paragraph 6. of this appendix is not found at a test temperature of 5 °C (9 °F) above its flash point, repeat the complete procedure with new test portions, but at a test temperature of 20 °C (36 °F) above its flash point.
The material must be assessed either as not sustaining combustion or as sustaining combustion. Sustained combustion must be reported at either of the heating times if one of the following occurs with either of the test portions:
(a) When the test flame is in the “off” position, the test portion ignites and sustains combustion;
(b) The test portion ignites while the test flame is in the test position for 15 s, and sustains combustion for more than 15 s after the test flame has been returned to the “off” position.
Intermittent flashing may not be interpreted as sustained combustion. Normally, at the end of 15 s, the combustion has either clearly ceased or continues. In cases of doubt, the material must be deemed to sustain combustion.
Appendix I to Part 173 – Calculation Method
PART 174 – CARRIAGE BY RAIL
Subpart A – General Requirements
§ 174.1 Purpose and scope.
This part prescribes requirements in addition to those contained in parts 171, 172, 173, and 179 of this subchapter, to be observed with respect to the transportation of hazardous materials in or on rail cars.
§ 174.2 Limitation on actions by states, local governments, and Indian tribes.
Sections 5125 and 20106 of Title 49, United States Code, limit the authority of states, political subdivisions of states, and Indian tribes to impose requirements on the transportation of hazardous materials in commerce. A state, local, or Indian tribe requirement on the transportation of hazardous materials by rail may be preempted under either 49 U.S.C. 5125 or 20106, or both.
(a) Section 171.1(f) of this subchapter describes the circumstances under which 49 U.S.C. 5125 preempts a requirement of a state, political subdivision of a state, or Indian tribe.
(b) Under the Federal Railroad Safety Act (49 U.S.C. 20106), administered by the Federal Railroad Administration (see 49 CFR parts 200 through 244), laws, regulations and orders related to railroad safety, including security, shall be nationally uniform to the extent practicable. A state may adopt, or continue in force, a law, regulation, or order covering the same subject matter as a DOT regulation or order applicable to railroad safety and security (including the requirements in this subpart) only when an additional or more stringent state law, regulation, or order is necessary to eliminate or reduce an essentially local safety or security hazard; is not incompatible with a law, regulation, or order of the United States Government; and does not unreasonably burden interstate commerce.
§ 174.3 Unacceptable hazardous materials shipments.
No person may accept for transportation or transport by rail any shipment of hazardous material that is not in conformance with the requirements of this subchapter.
§ 174.5 Carrier’s materials and supplies.
This subchapter applies to the transportation of a carrier’s materials and supplies moving by rail, except that the shipper’s certification is not required when these materials and supplies are being transported by the carrier who owns them. The requirements of this subchapter do not apply to railway torpedoes or fusees when carried in engines or rail cars. Railway torpedoes must be in closed metal boxes when not in use.
§ 174.9 Safety and security inspection and acceptance.
(a) At each location where a hazardous material is accepted for transportation or placed in a train, the carrier must inspect each rail car containing the hazardous material, at ground level, for required markings, labels, placards, securement of closures, and leakage. These inspections may be performed in conjunction with inspections required under parts 215 and 232 of this title.
(b) For each rail car containing an amount of hazardous material requiring placarding in accordance with § 172.504 of this subchapter, the carrier must visually inspect the rail car at ground level for signs of tampering, including closures and seals, for suspicious items or items that do not belong, and for other signs that the security of the car may have been compromised, including the presence of an improvised explosive device. As used in this section, an improvised explosive device is a device fabricated in an improvised manner incorporating explosives or destructive, lethal, noxious, pyrotechnic, or incendiary chemicals in its design, and generally includes a power supply, a switch or timer, and a detonator or initiator. The carrier should be particularly attentive to signs that security may have been compromised on rail cars transporting materials covered by § 172.820 of this subchapter, rail carload quantities of ammonium nitrate or ammonium nitrate mixtures in solid form, or hazardous materials of interest based on current threat information.
(c) If a rail car does not conform to the safety and security requirements of this subchapter, the carrier may not forward or transport the rail car until the deficiencies are corrected or the car is approved for movement in accordance with § 174.50.
(d) Where an indication of tampering or suspicious item is found, a carrier must take appropriate action to ensure the security of the rail car and its contents have not been compromised before accepting the rail car for further movement. If the carrier determines that the security of the rail car has been compromised, the carrier must take action, in conformance with its existing security plan (see subpart I of part 172 of this subchapter) to address the security issues before forwarding the rail car for further movement.
§ 174.14 Movements to be expedited.
(a) A carrier must forward each shipment of hazardous materials promptly and within 48 hours (Saturdays, Sundays, and holidays excluded), after acceptance at the originating point or receipt at any yard, transfer station, or interchange point, except that where biweekly or weekly service only is performed, a shipment of hazardous materials must be forwarded on the first available train.
(b) A tank car loaded with any Division 2.1 (flammable gas), Division 2.3 (poisonous gas) or Class 3 (flammable liquid) material, may not be received and held at any point, subject to forwarding orders, so as to defeat the purpose of this section or of § 174.204 of this subchapter.
§ 174.16 Removal and disposition of hazardous materials at destination.
(a) Delivery at non-agency stations. A shipment of Class 1 (explosive) materials may not be unloaded at non-agency stations unless the consignee is there to receive it or unless properly locked and secure storage facilities are provided at that point for its protection. If delivery cannot be so made, the shipment must be taken to next or nearest agency station for delivery.
(b) Delivery at agency stations. A carrier shall require the consignee of each shipment of hazardous materials to remove the shipment from carrier’s property within 48 hours (exclusive of Saturdays, Sundays, and holidays) after notice of arrival has been sent or given. If not so removed, the carrier shall immediately dispose of the shipments as follows:
(1) Division 1.1 or 1.2 (explosive) materials: If safe storage is available, by storage at the owner’s expense; if safe storage is not available, by return to the shipper, sale, or destruction under supervision of a competent person; or if safety requires, by destruction under supervision of a competent person.
(2) Hazardous materials, except Division 1.1 or 1.2 (explosive) materials, in carload shipments: By storage on the carrier’s property; by storage on other than the carrier’s property, if safe storage on the carrier’s property is not available; or by sale at expiration of 15 calendar days after notice of arrival has been sent or given to the consignee, provided the consignor has been notified of the non-delivery at the expiration of a 48-hour period and orders for disposition have not been received.
(3) Hazardous materials, except Division 1.1 or 1.2 (Class A explosive) materials, in less-than-carload shipments: By return to the shipper if notice of non-delivery was requested and given the consignor as prescribed by the carrier’s tariff, and orders for return to shipper have been received; by storage on the carrier’s property; by storage on other than the carrier’s property, if safe storage on carrier’s property is not available; or by sale at expiration of 15 calendar days after notice of arrival has been sent or given to the consignee, provided the consignor has been notified of non-delivery at expiration of a 48-hour period and orders for disposition have not been received.
§ 174.20 Local or carrier restrictions.
(a) When local conditions make the acceptance, transportation, or delivery of hazardous materials unusually hazardous, local restrictions may be imposed by the carrier.
(b) Each carrier must report to the Bureau of Explosives for publication the full information as to any restrictions which it imposes against the acceptance, delivery, or transportation of hazardous materials, over any portion of its lines under this section.
Subpart B – General Operating Requirements
§ 174.24 Shipping papers.
(a) A person may not accept a hazardous material for transportation or transport a hazardous material by rail unless that person receives a shipping paper prepared in accordance with part 172 of this subchapter, unless the material is excepted from shipping paper requirements under this subchapter. Only an initial carrier within the United States must receive and retain a copy of the shipper’s certification as required by § 172.204 of this subchapter. This section does not apply to a material that is excepted from shipping paper requirements by this subchapter.
(b) Each person receiving a shipping paper required by this section must retain a copy or an electronic image thereof, that is accessible at or through its principal place of business and must make the shipping paper available, upon request, to an authorized official of a Federal, State, or local government agency at reasonable times and locations. For a hazardous waste, each shipping paper copy must be retained for three years after the material is accepted by the initial carrier. For all other hazardous materials, each shipping paper copy must be retained for one year after the material is accepted by the initial carrier. Each shipping paper copy must include the date of acceptance by the initial carrier. The date on the shipping paper may be the date a shipper notifies the rail carrier that a shipment is ready for transportation, as indicated on the waybill or bill of lading, as an alternative to the date the shipment is picked up, or accepted, by the carrier.
§ 174.26 Notice to train crews.
(a) The train crew must have a document that reflects the current position in the train of each rail car containing a hazardous material. The train crew must update the document to indicate changes in the placement of a rail car within the train. For example, the train crew may update the document by handwriting on it or by appending or attaching another document to it.
(b) A member of the crew of a train transporting a hazardous material must have a copy of a document for the hazardous material being transported showing the information required by part 172 of this subchapter, including the requirements in § 172.604(b) applicable to emergency response information.
§ 174.50 Nonconforming or leaking packages.
A leaking non-bulk package may not be forwarded until repaired, reconditioned, or overpacked in accordance with § 173.3 of this subchapter. Except as otherwise provided in this section, a bulk packaging that no longer conforms to this subchapter may not be forwarded by rail unless repaired or approved for movement by the Associate Administrator for Safety, Federal Railroad Administration, or for cross-border movements to or from Canada, moved in accordance with the TDG Regulations (see § 171.12) or a Temporary Certificate issued by the Competent Authority of Canada, as applicable. For FRA Approval, notification and approval must be in writing, or through telephonic or electronic means, with subsequent written confirmation provided within two weeks. For the applicable address and telephone number, see § 107.117(d)(4) of this chapter. A leaking bulk package containing a hazardous material may be moved without repair or approval only so far as necessary to reduce or to eliminate an immediate threat or harm to human health or to the environment when it is determined its movement would provide greater safety than allowing the package to remain in place. In the case of a liquid leak, measures must be taken to prevent the spread of liquid.
Subpart C – General Handling and Loading Requirements
§ 174.55 General requirements.
(a) Each package containing a hazardous material being transported by rail in a freight container or transport vehicle must be loaded so that it cannot fall or slide and must be safeguarded in such a manner that other freight cannot fall onto or slide into it under conditions normally incident to transportation. When this protection cannot be provided by using other freight, it must be provided by blocking and bracing. For examples of blocking and bracing in freight containers and transport vehicles, see Bureau of Explosives Pamphlet No. 6 and the Intermodal Loading Guide for Products in Closed Trailers and Containers (IBR, see § 171.7 of this subchapter).
(b) Each package containing a hazardous material bearing package orientation markings prescribed in § 172.312 of this subchapter must be loaded within a transport vehicle or freight container to remain in the correct position indicated by those markings during transportation.
(c) The doors of a freight container or transport vehicle may not be used to secure a load that includes a package containing a hazardous material unless the doors meet the design strength requirements of Specification M-930 (for freight containers) and M-931 (for trailers) in the AAR’s specification for “Specially Equipped Freight Car and Intermodal Equipment” (IBR, see § 171.7 of this subchapter) and the load is also within the limits of the design strength requirements for the doors.
§ 174.57 Cleaning cars.
All hazardous material which has leaked from a package in any rail car or on other railroad property must be carefully removed.
§ 174.59 Marking and placarding of rail cars.
No person may transport a rail car carrying hazardous materials unless it is marked and placarded as required by this subchapter. Placards and car certificates lost in transit must be replaced at the next inspection point, and those not required must be removed at the next terminal where the train is classified. For Canadian shipments, required placards lost in transit, must be replaced either by those required by part 172 of this subchapter or by those authorized under § 171.12.
§ 174.61 Transport vehicles and freight containers on flat cars.
(a) A transport vehicle, freight container, or package containing a hazardous material must be designed and loaded so that it will not become damaged to an extent that would affect its integrity under conditions normally incident to transportation. Each unit must be secured on a flatcar so that it cannot permanently change position during transit. Packages of hazardous materials contained therein must be loaded and braced as provided by §§ 174.101, 174.112, 174.115 and 174.55. Placards must be applied when prescribed by part 172 of this subchapter and part 174.
(b) Except as specified in § 173.21, a truck body, trailer, or freight container equipped with heating or refrigerating equipment which has fuel or any article classed as a hazardous material may be loaded and transported on a flat car as part of a joint rail highway movement. The heating or refrigerating equipment is considered to be a part of the truck body or trailer and is not subject to any other requirements of this subchapter. The truck body, trailer, or freight container must be secured on the flatcar so that it cannot change position during transit.
§ 174.63 Portable tanks, IM portable tanks, IBCs, Large Packagings, cargo tanks, and multi-unit tank car tanks.
(a) A carrier may not transport a bulk packaging (e.g., portable tank, IM portable tank, IBC, Large Packaging, cargo tank, or multi-unit tank car tank) containing a hazardous material in container-on-flatcar (COFC) or trailer-on-flatcar (TOFC) service except as authorized by this section or unless approved for transportation by the Associate Administrator for Safety, FRA.
(b) A bulk packaging containing a hazardous material (including IM 101 and IM 102 when appropriate according to dimensions and weight distribution) may be transported inside a fully closed transport vehicle or fully closed freight container provided it is properly secured with a restraint system that will prevent it from changing position, sliding into other packages, or contacting the side or end walls (including doors) under conditions normally incident to transportation.
(c) When not transported in conformance with and subject to paragraph (b) of this section, a bulk packaging may be transported in COFC service or TOFC service subject to the following conditions as applicable:
(1) The bulk packaging contains a material packaged in accordance with § 173.240, § 173.241, § 173.242, or § 173.243 of this subchapter;
(2) The tank and flatcar must comply with the applicable requirements of the HMR concerning their specification.
(3) For TOFC service, the trailer chassis conforms to requirements in paragraphs 3, 4, 5, and 6 of AAR Specification M-943, “Container Chassis For TOFC Service” of the AAR specification for “Specially Equipped Freight Car and Intermodal Equipment” (IBR, see § 171.7 of this subchapter);
(4) For COFC service, the container support and securement systems conform to requirements in Specification M-952, “Intermodal Container Support and Securement Systems for Freight Cars”, of the AAR specification for “Specially Equipped Freight Car and Intermodal Equipment” (IBR, see § 171.7 of this subchapter);
(5) If transported in a well car –
(i) The tank is not in a double-stacked configuration (i.e., no freight container or portable tank is placed above or below the tank); and
(ii) The tank is transported in the well with its outlet valve facing outward towards the end of the well and away from any adjacent tank or container; and
(6) All securement fittings shall be fully engaged and in the locked position, provided; however, if the tank is transported in a well car, it must be loaded into a well appropriate for the length of the container and any void filling device present must be secured in its designed appropriate position.
(d) An approval in effect on February 28, 1991 for the transportation of portable tanks or IM portable tanks in TOFC or COFC service expires on the date stated in the approval letter or June 15, 1995, whichever is later.
(e) A carrier may not transport a cargo tank or multi-unit tank car tank containing a hazardous material in TOFC or COFC service unless approved for such service by the Associate Administrator for Safety, FRA. However, in the event of an accident or incident, no such approval is necessary for the transportation of a cargo tank containing a hazardous material in TOFC service under the following condition(s):
(1) There is an emergency need for the cargo tank in order to mitigate the consequences of an incident; and
(2) Movement of the cargo tank is limited to transportation necessary for emergency purposes.
§ 174.67 Tank car unloading.
For transloading operations, the following rules must be observed:
(a) General requirements. (1) Unloading operations must be performed by hazmat employees properly instructed in unloading hazardous materials and made responsible for compliance with this section.
(2) Each hazmat employee who is responsible for unloading must apply the handbrake and block at least one wheel to prevent motion in any direction. If multiple tank cars are coupled together, sufficient hand brakes must be set and wheels blocked to prevent motion in both directions.
(3) Each hazmat employee who is responsible for unloading must secure access to the track to prevent entry by other rail equipment, including motorized service vehicles. This requirement may be satisfied by lining each switch providing access to the unloading area against shifting and securing each switch with an effective locking device, or by using derails, portable bumper blocks, or other equipment that provides an equivalent level of safety.
(4) Each hazmat employee who is responsible for unloading must display caution signs on the track or on the tank cars to warn persons approaching the cars from the open end of the track and must be left up until after all closures are secured and the cars are in proper condition for transportation. The caution signs must be of metal or other durable material, rectangular, at 30.48 cm (12 inches) high by 38.10 cm (15 inches) wide, and bear the word “STOP.” The word “STOP” must appear in letters at least 10.16 cm (4 inches) high. The letters must be white on a blue background. Additional words, such as “Tank Car Connected” or “Crew at Work,” may also appear in white letters under the word “STOP.”
(5) The transloading facility operator must maintain written safety procedures (such as those it may already be required to maintain pursuant to the Department of Labor’s Occupational Safety and Health Administration requirements in 29 CFR 1910.119 and 1910.120) in a location where they are immediately available to hazmat employees responsible for the transloading operation.
(6) Before a manhole cover or outlet valve cap is removed from a tank car, the car must be relieved of all interior pressure by cooling the tank with water or by venting the tank by raising the safety valve or opening the dome vent at short intervals. However, if venting to relieve pressure will cause a dangerous amount of vapor to collect outside the car, venting and unloading must be deferred until the pressure is reduced by allowing the car to stand overnight, otherwise cooling the contents, or venting to a closed collection system. These precautions are not necessary when the car is equipped with a manhole cover which hinges inward or with an inner manhole cover which does not have to be removed to unload the car, and when pressure is relieved by piping vapor into a condenser or storage tank.
(b) After the pressure is released, for unloading processes that require the removal of the manhole cover, the seal must be broken and the manhole cover removed as follows:
(1) Screw type. The cover must be loosened by placing a bar between the manhole cover lug and knob. After two complete turns, so that the vent openings are exposed, the operation must be stopped, and if there is any sound of escaping vapor, the cover must be screwed down tightly and the interior pressure relieved as prescribed in paragraph (a)(6) of this section, before again attempting to remove the cover.
(2) Hinged and bolted type. All nuts must be unscrewed one complete turn, after which same precautions as prescribed for screw type cover must be observed.
(3) Interior type. All dirt and cinders must be carefully removed from around the cover before the yoke is unscrewed.
(c) When the car is unloaded through a bottom outlet valve, for unloading processes that require the removal of the manhole cover, the manhole cover must be adjusted as follows:
(1) Screw type. The cover must be put in place, but not entirely screwed down, so that air may enter the tank through the vent holes in threaded flange of the cover.
(2) Hinged and bolted type. A non-metallic block must be placed under one edge of the cover.
(3) Interior type. The screw must be tightened up in the yoke so that the cover is brought up within one-half inch of the closed position.
(d) When unloading through the bottom outlet of a car equipped with an interior manhole type cover, and in each case where unloading is done through the manhole (unless a special cover with a safety vent opening and a tight connection for the discharge outlet is used), the manhole must be protected by asbestos or metal covers against the entrance of sparks or other sources of ignition of vapor, or by being covered and surrounded with wet burlap or similar cloth material. The burlap or other cloth must be kept damp by the replacement or the application of water as needed.
(e) Seals or other substances must not be thrown into the tank and the contents may not be spilled over the car or tank.
(f) The valve rod handle or control in the dome must be operated several times to see that outlet valve in bottom of tank is on its seat before valve cap is removed.
(g) The valve cap, or the reducer when a large outlet is to be used, must be removed with a suitable wrench after the set screws are loosened and a pail must be placed in position to catch any liquid that may be in the outlet chamber. If the valve cap or reducer does not unscrew easily, it may be tapped lightly with a mallet or wooden block in an upward direction. If leakage shows upon starting the removal, the cap or reducer may not be entirely unscrewed. Sufficient threads must be left engaged and sufficient time allowed to permit the controlled escape of any accumulation of liquid in the outlet chamber. If the leakage stops or the rate of leakage diminishes materially, the cap or reducer may be entirely removed. If the initial rate of leakage continues, further efforts must be made to seat the outlet valve (see paragraph (f) of this section). If this fails, the cap or reducer must be screwed up tight and the tank must be unloaded through the dome. If upon removal of the outlet cap the outlet chamber is found to be blocked with frozen liquid or any other matter, the cap must be replaced immediately and a careful examination must be made to determine whether the outlet casting has been cracked. If the obstruction is not frozen liquid, the car must be unloaded through the dome. If the obstruction is frozen liquid and no crack has been found in the outlet casting, the car may, if circumstances require it, be unloaded from the bottom by removing the cap and attaching unloading connections immediately. Before opening the valve inside the tank car with a frozen liquid blockage:
(1) Steam must be applied to the outside of the outlet casting or the outlet casting must be wrapped with burlap or other rags and hot water applied to the wrapped casting to melt the frozen liquid; or
(2) For combustible liquid or Class 3 liquid petroleum distillate fuels, the blockage may be cleared by attaching a fitting to the outlet line and applying nitrogen at a pressure not to exceed 100 psig.
(h) Unloading connections must be securely attached to unloading pipes on the dome or to the bottom discharge outlets before any discharge valves are opened.
(i) Throughout the entire period of unloading and while a tank car has unloading equipment attached, the facility operator must assure that the tank car is:
(1) Attended by a designated hazmat employee who is physically present and who has an unobstructed view of the unloading operation; or
(2) Monitored by a signaling system (e.g., video system, sensing equipment, or mechanical equipment) that is observed by a designated hazmat employee located either in the immediate area of the tank car or at a remote location within the facility, such as a control room. The signaling system must –
(i) Provide a level of surveillance equivalent to that provided in subparagraph (1) of this paragraph (i); and
(ii) Provide immediate notification to a designated hazmat employee of any system malfunction or other emergency so that, if warranted, responsive actions may be initiated immediately.
(j) Attendance is not required when piping is attached to a top outlet of a tank car, equipped with a protective housing required under § 179.100-12 of this subchapter, for discharge of lading under the following conditions:
(1) All valves are tightly closed.
(2) The piping is not connected to hose or other unloading equipment and is fitted with a cap or plug of appropriate material and construction.
(3) The piping extends no more than 15.24 centimeters (6 inches) from the outer edge of the protective housing.
(k) In the absence of the unloader, a tank car may stand with unloading connections attached when no product is being transferred under the following conditions:
(1) The facility operator must designate a hazmat employee responsible for on-site monitoring of the transfer facility. The designated hazmat employee must be made familiar with the nature and properties of the product contained in the tank car; procedures to be followed in the event of an emergency; and, in the event of an emergency, have the ability and authority to take responsible actions.
(2) When a signaling system is used in accordance with paragraph (i) of this section, the system must be capable of alerting the designated hazmat employee in the event of an emergency and providing immediate notification of any monitoring system malfunction. If the monitoring system does not have self-monitoring capability, the designated hazmat employee must check the monitoring system hourly for proper operation.
(3) The tank car and facility shutoff valves must be secured in the closed position.
(4) Brakes must be set and wheels locked in accordance with paragraph (a)(2) of this section.
(5) Access to the track must be secured in accordance with paragraph (a)(3) of this section.
(l) As soon as a tank car is completely unloaded, all valves must be made tight by the use of a bar, wrench or other suitable tool, the unloading connections must be removed and all other closures made tight.
(m) Railroad defect cards may not be removed.
(n) If oil or gasoline has been spilled on the ground around connections, it must be covered with fresh, dry sand or dirt.
(o) All tools and implements used in connection with unloading must be kept free of oil, dirt, and grit.
§ 174.81 Segregation of hazardous materials.
(a) This section applies to materials which meet one or more of the hazard classes defined in this subchapter and are in packages which are required to be labeled or placarded under the provisions of part 172 of this subchapter.
(b) When a rail car is to be transported by vessel, other than a ferry vessel, hazardous materials on or within that rail car must be stowed and segregated in accordance with § 176.83(b) of this subchapter.
(c) Except as provided in § 173.12(e) of this subchapter, cyanides, cyanide mixtures or solutions may not be stored, loaded and transported with acids; Division 4.2 materials may not be stored, loaded and transported with Class 8 liquids; and Division 6.1 Packing Group I, Hazard Zone A material may not be stored, loaded and transported with Class 3 material, Class 8 liquids, and Division 4.1, 4.2, 4.3, 5.1 or 5.2 material.
(d) Except as otherwise provided in this subchapter, hazardous materials must be stored, loaded or transported in accordance with the following table and other provisions of this section:

(e) Instructions for using the segregation table for hazardous materials in paragraph (d) of this section are as follows:
(1) The absence of any hazard class or division, or a blank space in the table indicates that no restrictions apply.
(2) The letter “X” in the table indicates that these materials may not be loaded, transported, or stored together in the same rail car or storage facility during the course of transportation.
(3) The letter “O” in the table indicates that these materials may not be loaded, transported, or stored together in the same rail car or storage facility during the course of transportation unless separated in a manner that, in the event of leakage from packages under conditions normally incident to transportation, commingling of hazardous materials would not occur. Notwithstanding the methods of separation employed, Class 8 (corrosive) liquids may not be loaded above or adjacent to Class 4 (flammable) or Class 5 (oxidizing) materials; except that shippers may load carload shipments of such materials together when it is known that the mixture of contents would not cause a fire or a dangerous evolution of heat or gas.
(4) The “*” in the table indicates that segregation among different Class 1 (explosive) materials is governed by the compatibility table in paragraph (f) of this section.
(5) The note “A” in the second column of the table means that, notwithstanding the requirements of the letter “X”, ammonium nitrate fertilizer may be loaded or stored with Division 1.1 (explosive) or Division 1.5 materials.
(6) When the § 172.101 table or § 172.402 of this subchapter requires a package to bear a subsidiary hazard label, segregation appropriate to the subsidiary hazard must be applied when that segregation is more restrictive than that required by the primary hazard. However, hazardous materials of the same class may be loaded and transported together without regard to segregation required by any secondary hazard if the materials are not capable of reacting dangerously with each other and causing combustion or dangerous evolution of heat, evolution of flammable, poisonous, or asphyxiant gases, or formation of corrosive or unstable materials.
(f) Class 1 (explosive) materials may not be loaded, transported, or stored together, except as provided in this section, and in accordance with the following table:

(g) Instructions for using the compatibility table for Class 1 (explosive) materials in paragraph (f) of this section are as follows:
(1) A blank space in the table indicates that no restrictions apply.
(2) The letter “X” in the table indicates that explosives of different compatibility groups may not be carried on the same rail car, unless packed in separate freight containers (e.g., two or more freight containers mounted upon the same rail car).
(3) The numbers in the table mean the following:
(i) “1” means explosives from compatibility group L may only be carried on the same rail car with an identical explosive.
(ii) “2” means any combination of explosives from compatibility group C, D, or E is assigned to compatibility group E.
(iii) “3” means any combination of explosives from compatibility group C, D, or E with those in compatibility group N is assigned to compatibility group D.
(iv) “4” means detonators and detonating primers, Division 1.4S (explosives), may not be loaded in the same car with Division 1.1 and 1.2 (explosive) materials.
(v) “5” means Division 1.4S fireworks may not be loaded in the same car with Division 1.1 or 1.2 (explosive) materials.
(vi) “6” means explosive articles in compatibility group G, other than fireworks and those requiring special stowage, may be loaded and transported with articles of compatibility groups C, D and E, provided no explosive substances are carried in the same rail car.
(h) Except as provided in paragraph (i) of this section, explosives of the same compatibility group but of different divisions may be transported together provided that the whole shipment is transported as though its entire contents were of the lower numerical division (i.e., Division 1.1 being lower than Division 1.2). For example, a mixed shipment of Division 1.2 (explosive) materials and Division 1.4 (explosive) materials, compatibility group D, must be transported as Division 1.2 (explosive) materials.
(i) When Division 1.5 materials, compatibility group D are transported in the same freight container as Division 1.2 (explosive) materials, compatibility group D, the shipment must be transported as Division 1.1 (explosive) materials, compatibility group D.

Subpart E – Class I (Explosive) Materials
§ 174.101 Loading Class 1 (explosive) materials.
(a) Boxes containing Division 1.1 or 1.2 (explosive) materials must be loaded so that the ends of wooden boxes will not bear against sides of any fiberboard boxes and so that the ends of any box will not cause a pressure point on a small area of another box.
(b) Explosive bombs, unfuzed projectiles, rocket ammunition and rocket motors, Division 1.1, 1.2, or 1.3 (explosive) materials, which are not packed in wooden boxes, or large metal packages of incendiary bombs, each weighing 226 kg (500 pounds) or more, may be loaded in stock cars or in flat bottom gondola cars only if they are adequately braced. Boxed bombs, rocket ammunition and rocket motors, Division 1.1, 1.2, or 1.3 (explosive) materials, which due to their size cannot be loaded in closed cars, may be loaded in open-top cars or on flatcars, provided they are protected from the weather and accidental ignition.
(c) Boxes of Division 1.1 or 1.2 (explosive) materials packed in long cartridges, bags, or sift-proof liners, and containing no liquid explosive ingredient, may be loaded on their sides or ends.
(d) Division 1.1 or 1.2 (explosive) materials may not be loaded higher than any permanent car lining unless additional lining is provided as high as the lading.
(e) When the lading of a car includes any Class 1 (explosive) materials, the weight of the lading must be distributed insofar as possible to equalize the weight on each side of the car and over the trucks.
(f) Except when boxed, metal kegs containing Class 1 (explosive) materials must be loaded on their sides with their ends toward the ends of the car. Packages of Class 1 (explosive) materials may not be placed in the space opposite the doors unless the doorways are boarded on the inside as high as the lading. This paragraph does not apply to palletized packages if they are braced so they cannot fall or slide into the doorways during transportation.
(g) Wooden kegs, fiber kegs, barrels, and drums must be loaded on their sides or ends, to best suit the conditions.
(h) Packages containing any Division 1.1 or 1.2 (explosive) materials for (see § 174.104), detonators, detonator assemblies, or boosters with detonators must be securely blocked and braced to prevent the packages from changing position, falling to the floor, or sliding into each other, under conditions normally incident to transportation. Class 1 (explosive) materials must be loaded so as to avoid transfer at stations. For recommended methods of blocking and bracing, see Bureau of Explosives Pamphlets No. 6 and 6A. Heavy packages or containers must be trucked, rolled, or moved by skids, fork trucks, or other handling devices and may not be dropped from trucks, platforms, or cars. Planks for rolling trucks from platforms to cars must have beveled ends. Loading platforms and the shoes of each workman must be free from grit. All possible precautions must be taken against fire. Class 1 (explosive) materials must be kept in a safe place and inaccessible to unauthorized persons while being held by a carrier for loading or delivery.
(i) To prevent delays of local freight trains, when there are shipments of Class 1 (explosive) materials for different destinations loaded in a “peddler car” or “way car” the shipment for each destination must be stayed separately.
(j) Forwarding and transfer stations for Class 1 (explosive) materials must be provided with the necessary materials for staying.

(l) Division 1.1 or 1.2 (explosive) materials may not be loaded, transported, or stored in a rail car equipped with any type of lighted heater or open-flame device, or electric devices having exposed heating coils, or in a rail car equipped with any apparatus or mechanism utilizing an internal combustion engine in its operation.
(m) [Reserved]
(n) A container car or freight container on a flatcar or a gondola car other than a drop-bottom car, when properly loaded, blocked, and braced to prevent change of position under conditions normally incident to transportation, may be used to transport any Division 1.1 or 1.2 (explosive) material except black powder packed in metal containers. A freight container must be designed, constructed, and maintained so as to be weather tight and capable of preventing the entrance of sparks. In addition:
(1) A freight container must be of such design and so braced as to show no evidence of failure of the container or the bracing when subjected to impact from each end of at least 13 km (8.1 miles) per hour. Its efficiency shall be determined by actual test, using dummy loads equal in weight and general character to material to be shipped.
(2) A container car or car which is loaded with freight containers must be placarded with the Class 1 (explosive) materials placards as required by subpart F of part 172 of this subchapter and with properly executed car certificates as required by § 174.104.
(3) Lading must be so loaded, blocked, and braced within the freight container that it will not change position under impact from each end of at least 13 km (8.1 miles) per hour.
(o) Division 1.1, 1.2, or 1.3 (explosive) materials may be loaded and transported in a tight closed truck body or trailer on a flatcar. Wooden boxed bombs, rocket ammunition, and rocket motors, Division 1.1, 1.2, or 1.3 (explosive) materials, which due to their size cannot be loaded in tight, closed truck bodies or trailers, may be loaded in or on open-top truck bodies or trailers. However, they must be protected against accidental ignition. In addition:
(1) Each truck body or trailer must meet the requirements of part 177 of this subchapter, applicable to shipments of Class 1 (explosive) materials by motor vehicle.
(2) Each truck body or trailer must be secured on the rail car so that it will not permanently change position or show evidence of failure or impending failure of the method of securing the truck body or trailer under impact from each end of at least 13 km (8.1 miles) per hour. Its efficiency must be determined by actual test, using dummy loads equal in weight and general character to the material to be shipped. For recommended methods of blocking and bracing, see the Intermodal Loading Guide for Products in Closed Trailers and Containers (IBR, see § 171.7 of this subchapter).
(3) Lading must be loaded, blocked, and braced within or on the truck body or trailer so that the lading will not change position under impact from each end of at least 13 km (8.1 miles) per hour. For recommended methods of blocking and bracing, see the Intermodal Loading Guide for Products in Closed Trailers and Containers (IBR, see § 171.7 of this subchapter).
(4) Each rail car containing Class 1 (explosive) materials and each rail car loaded with truck bodies, trailers or containers containing Class 1 (explosive) materials must be placarded with Class 1 (explosive) materials placards as required by subpart F of part 172 of this subchapter and with properly executed car certificates as required by § 174.104.
(5) Each fuel tank of a heater or refrigerating machinery on the truck bodies or trailers must be drained and all automatic heating or refrigerating machinery must be made inoperative by disconnection of the automatic controls or the source of power for their operations.
§ 174.102 Forbidden mixed loading and storage.
(a) Division 1.1 or 1.2 (explosive) materials and initiating or priming explosives may not be transported together in the same rail car. Additionally, they may not be transported or loaded in the same rail car or stored on carrier property with charged electric storage batteries or with any hazardous material for which a NONFLAMMABLE GAS, FLAMMABLE GAS, FLAMMABLE LIQUID, FLAMMABLE SOLID, OXIDIZER, ORGANIC PEROXIDE, RADIOACTIVE or CORROSIVE label is required.
(b) Class 1 (explosive) materials may not be loaded together or with other hazardous materials, except as provided in § 174.81. See § 174.104 for loading shipments of Class 1 (explosive) materials or any other material in a placarded and certified car containing a shipment of Division 1.1 or 1.2 (explosive) materials.
§ 174.103 Disposition of damaged or astray shipments.
(a) Packages of Class 1 (explosive) materials found damaged or broken in transit may be repaired when practicable and not dangerous. A broken box of Division 1.1 or 1.2 (explosive) materials that cannot be repaired must be reinforced by stout wrapping paper and twine, placed in another strong box and surrounded by dry, fine sawdust or dry and clean cotton waste or elastic wads made from dry newspapers. A ruptured can or keg must be sealed and enclosed in a strong cloth bag of good quality and boxed. Damaged packages thus protected and properly marked may be forwarded. The box and waybill must be marked to indicate that it has been repacked.
(b) Care must be exercised in repacking damaged containers so that no spark is produced by contact of metal or other hard surfaces which could ignite loose particles of explosive compositions that may be strewn on car floors or freight. In addition, the car floors must be thoroughly swept, and washed with a plentiful supply of water. Iron-wheel trucks, metal hammers, or other metal tools that may produce sparks may not be used. Metal tools must be limited to those made of brass, bronze, or copper.
(c) Each package of Class 1 (explosive) materials showing evidence of leakage of liquid ingredients must:
(1) Be refused if leakage is discovered before acceptance;
(2) Be disposed of to a person who is competent and willing to remove them from the carrier’s property, if the leakage is discovered while the shipment is in transit; or
(3) Be removed immediately by consignee, if the leakage is discovered at the shipment’s destination.
(d) When the disposition required by paragraph (c) of this section cannot be made, the leaking package must be packed in other boxes large enough to permit enclosure and the leaking boxes must be surrounded by at least 5 cm (2 inches) of dry, fine sawdust or dry and clean cotton waste, and be stored in a station magazine or other safe place until the arrival of an inspector of the Bureau of Explosives, or other authorized person, to superintend the destruction or disposition of the condemned material.
(e) If careful inspection shows that an astray shipment of Class 1 (explosive) materials is in proper condition for safe transportation, it must be forwarded immediately to its destination if known, or returned to the shipper by the most practicable route.
(f) When a package in an astray shipment is not in proper condition for safe transportation (see paragraphs (a), (c), and (d) of this section), or when the name and address of the consignee and the shipper are unknown, disposition must be made as prescribed by paragraphs (c) and (d) of this section.
§ 174.104 Division 1.1 or 1.2 (explosive) materials; car selection, preparation, inspection, and certification.
(a) Except as provided in § 174.101 (b), (n), and (o), Division 1.1 or 1.2 (explosive) materials being transported by rail may be transported only in a certified and properly placarded closed car of not less than 36,300 kg (80,028 pounds) capacity, with steel underframes and friction draft gear or cushioned underframe, except that on a narrow-gauge railroad they may be transported in a car of less capacity as long as the car of greatest capacity and strength available is used.
(b) Each rail car used for transporting Division 1.1 or 1.2 (explosive) materials must meet the following requirements as applicable:
(1) The car must be equipped with air brakes, hand brakes, and roller bearings which are in condition for service.
(2) The car may not have any holes or cracks in the roof, sides, ends, or doors through which sparks may enter, or unprotected decayed spots which may hold sparks and start a fire.
(3) The roof of the car must be carefully inspected from the outside for decayed spots, especially under or near the running board, and such spots must be covered or repaired to prevent their holding fire from sparks. A car with a roof generally decayed, even if tight, may not be used.
(4) The doors must close tightly so that sparks cannot get in at the joints, and, if necessary to achieve this degree of tightness, the doors must be stripped. The stripping should be placed on the inside and fastened to the door frames where it will form a shoulder against which the closed doors are pressed by means of wedges or cleats in door shoes or keepers. The openings under the doors should be similarly closed. The hasp fastenings must be examined with the doors closed and fastened, and the doors must be cleated when necessary to prevent them from shifting. When the car is opened for any reason, the wedges or cleats must be replaced before car containing Class 1 (explosive) materials is permitted to proceed.
(5) The roller bearings and the trucks must be carefully examined and put in such condition as to reduce to a minimum the danger of hotboxes or other failure necessitating the setting out of the car before reaching its destination.
(6) The car must be carefully swept out before it is loaded. For less-than-carload shipments the space in which the packages are to be loaded must be carefully swept. If evidence of a potential hazardous residue is apparent after the floor has been swept, the carrier must either decontaminate the car or provide a suitable substitute car.
(7) Any holes in the floor or lining must be repaired and special care taken that there are no projecting nails or bolts or exposed pieces of metal which may work loose or produce holes in packages of Class 1 (explosive) materials during transit. Protruding nails in the floor or lining which have worked loose must be drawn, and if necessary for the purpose of fastening the floor or lining, new nails must be driven through other parts thereof.
(8) Metal floor plates must be completely covered with wood, plywood, or fiber or composition sheets of adequate thickness and strength to prevent contact of the floor plates with the packages of Class 1 (explosive) materials under conditions incident to transportation, except that the covering of metal floor plates is not necessary for carload shipments loaded by the Department of Defense provided the Class 1 (explosive) materials are of such nature that they are not liable to leakage of dust, powder, or vapor which might become the cause of an explosion.
(9) If the car is equipped with automobile loading devices, it may not be used unless the loading device is securely attached to the roof of the car with fastenings supplementing those already provided and so fixed that it cannot fall.
(10) The car must be equipped with high-friction composition brake shoes (except metal deck flat cars used for COFC/TOFC service may be equipped with high phosphorus cast iron brakeshoes) and brake rigging designed for this type of brake shoe. Each brake shoe on the car must be at least 1 cm (0.4 inch) thick, and in safe and suitable condition for service.
(11) The car must have either a metal subfloor with no combustible material exposed beneath the car, or metal spark shields extending from center sill to side sills and from end sills to at least 30 cm (12 inches) beyond the extreme treads of the inside wheels of each truck, which are tightly fitted against the subfloor so that there is no vacant space or combustible material exposed. The metal subfloor or spark shields may not have an accumulation of oil, grease, or other debris which could support combustion.
(c) Before Division 1.1 or 1.2 (explosive) materials may be loaded into a rail car, the car must have been inspected and certified to be in compliance with the requirements of paragraph (b) of this section by a qualified person designated under § 215.11 of this title. The certification shall be made in Car Certificate No. 1 on the form prescribed in paragraph (f) of this section.
(d) If the carrier furnishes the car to a shipper for loading Division 1.1 or 1.2 (explosive) materials, the shipper or his authorized employee shall, before commencing the loading of the car, inspect the interior thereof, and after loading certify to the proper condition of the car and the loading. This certification shall be made on the first signature line in Car Certificate No. 2 on the form prescribed in paragraph (f) of this section.

Subpart C – General Handling and Stowage
§ 176.57 Supervision of handling and stowage.
(a) Hazardous materials may be handled or stowed on board a vessel only under the direction and observation of a responsible person assigned this duty.
(b) For a vessel engaged in coastwise voyages, or on rivers, bays, sounds or lakes, including the Great Lakes when the voyage is not foreign-going, the responsible person may be an employee of the carrier and assigned this duty by the carrier, or a licensed officer attached to the vessel and assigned by the master of the vessel.
(c) For a domestic vessel engaged in a foreign-going or intercoastal voyage, the responsible person must be an officer possessing an unexpired license issued by the USCG and assigned this duty by the master of the vessel.
(d) For a foreign vessel, the responsible person must be an officer of the vessel assigned this duty by the master of the vessel.
§ 176.58 Preparation of the vessel.
(a) Each hold or compartment in which hazardous materials are to be stowed must be free of all debris before the hazardous materials are stowed. Bilges must be examined and all residue of previous cargo removed.
(b) All decks, gangways, hatches, and cargo ports over or through which hazardous materials must be passed or handled in loading or unloading must be free of all loose materials before cargo handling operations begin.
(c) No debris that creates a fire hazard or a hazardous condition for persons engaged in handling hazardous materials may be on the weather deck of a vessel during loading or unloading operations.
(d) Hatch beams and hatch covers may not be stowed in a location that would interfere with cargo handling.
§ 176.60 “No Smoking” signs.
When smoking is prohibited during the loading, stowing, storing, transportation, or unloading of hazardous materials by this part, the carrier and the master of the vessel are jointly responsible for posting “NO SMOKING” signs in conspicuous locations.
§ 176.63 Stowage locations.
(a) The table in § 172.101 of this subchapter specifies generally the locations authorized for stowage of the various hazardous materials on board vessels. This part prescribes additional requirements with respect to the stowage of specific hazardous materials in addition to those authorized in § 172.101 of this subchapter. This section sets forth the basic physical requirements for the authorized locations. Hazardous materials offered for transport as limited quantities are allocated stowage category A and are not subject to any of the specific stowage requirements indicated in column 10B in § 172.101 of this subchapter for the material being transported.
(b) To qualify as “on deck” stowage, the location must be on the weather deck. If the location is in a house on the weather deck, the location must have a permanent structural opening to the atmosphere, such as a door, hatch, companionway or manhole, and must be vented to the atmosphere. The location may not have any structural opening to any living quarters, cargo, or other compartment unless the opening has means for being closed off and secured. Any deck house containing living quarters, a steering engine, a refrigerating unit, a refrigerated stowage box, or a heating unit may not be used unless that area is isolated from the cargo stowage area by a permanent, and tight, metallic bulkhead. Stowage in a shelter or ‘tween deck is not considered to be “on deck”. A barge that is vented to the atmosphere and is stowed on deck on a barge-carrying ship is considered to be “on deck”. When an entry in § 172.101 of this subchapter requires “on-deck” stowage and is qualified by the requirement “protected from sources of heat”, the stowage must be protected from the direct rays of the sun by means of structural erections or awnings except that such protection is not required for shipment in portable tanks.
(c) To qualify as “under deck” stowage, the location must be in a hold or compartment below the weather deck capable of being ventilated and allotted entirely to the carriage of cargo. It must be bounded by permanent steel decks and bulkheads or the shell of the vessel. The deck openings must have means for effectively closing the hold or compartment against the weather, and in the case of superimposed holds, for effectively closing off each hold. A hold or compartment containing a crew passage formed by battens or by mesh or wire screen bulkhead may not be used for the stowage of any hazardous material unless a watchman is provided for this area.
(d) To qualify as “under deck away from heat”, the location must be under deck and have built-in means for ventilation. If it is subject to heat from any artificial source, it only qualifies for the stowage of those hazardous materials for which “under deck” stowage is authorized.
(e) Notwithstanding the stowage provisions given in the table in § 172.101 of this subchapter, empty packages containing residue, including IBCs and large packages, may be stowed “on deck” or “under deck” in a mechanically ventilated cargo space. However, empty pressure receptacles containing residue that carry a label of class 2.3 must be stowed “on deck” and waste aerosols must be stowed in accordance with the table in § 172.101 of this subchapter.
(f) Stowage of containers on board hatchless container ships. (1) Containers holding a hazardous material may be stowed in or vertically above a hatchless container hold if the following conditions are met:
(1) All hazardous materials are permitted for under deck stowage as specified in the Table in § 172.101 of this subchapter; and
(2) The hatchless container hold is in full compliance with the provisions of SOLAS, Chapter II-2/Regulation 19 (IBR; see § 171.7 of this subchapter), applicable to enclosed container cargo spaces, as appropriate for the cargo transported.
§ 176.65 Alternative stowage procedures.
When a hazardous material is to be loaded on board a vessel and it is shown to the satisfaction of the Coast Guard Captain of the Port for the place where the vessel is being loaded that it is impracticable to comply with a stowage location requirement specified in the § 172.101 table of this subchapter or a segregation, handling or stowage requirement specified in this part, the Captain of the Port may authorize in writing the use of an alternative stowage location or method of segregation, handling or stowage subject to such conditions as he finds will insure a level of safety at least equal to that afforded by the regulatory requirement concerned.
§ 176.69 General stowage requirements for hazardous materials.
(a) Hazardous materials (except as provided in paragraph (c) of this section and Class 9 (miscellaneous hazardous) materials) must be stowed in a manner that will facilitate inspection during the voyage, their removal from a potentially dangerous situation, and the removal of packages in case of fire.
(b) Each package marked in accordance with § 172.312(a)(2) of this subchapter must be stowed as to remain in the position indicated during transportation.
(c) If a vessel designed for and carrying hazardous materials in freight containers or a vessel designed for and carrying hazardous materials in barges is equipped with a fixed fire extinguishing and fire detection system, the freight containers or barges need not be stowed in the manner required by paragraph (a) of this section. When freight containers or barges containing hazardous materials are stowed on deck, they need not be stowed in the manner required by paragraph (a) of this section if fire fighting equipment capable of reaching and piercing the freight container or barge is on board the vessel.
(d) Packages of hazardous materials must be secured and dunnaged to prevent shifting in any direction. Vertical restraints are not required if the shape of the package and the stuffing pattern preclude shifting of the load.
(e) Packages of hazardous materials must be braced and dunnaged so that they are not likely to be pierced by the dunnage or crushed by a superimposed load.
§ 176.70 Stowage requirements for marine pollutants.
(a) Marine pollutants must be properly stowed and secured to minimize the hazards to the marine environment without impairing the safety of the ship and the persons on board.
(b) Where stowage is permitted “on deck or under deck”, under deck stowage is preferred except when a weather deck provides equivalent protection.
(c) Where stowage “on deck only” is required, preference should be given to stowage on well-protected decks or to stowage inboard in sheltered areas of exposed decks.
§ 176.72 Handling of break-bulk hazardous materials.
(a) A metal bale hook may not be used for handling any package of hazardous materials.
(b) The use of equipment designed to lift or move cargo by means of pressure exerted on the packages may not be used for handling any package of hazardous materials if the device can damage the package or the package is not designed to be moved in that manner.
(c) Pallets, slings, cargo nets and other related equipment used in loading packages of hazardous materials must give adequate support to the packages. The packages must be contained so that they are not able to fall during loading.
§ 176.74 On deck stowage of break-bulk hazardous materials.
(a) Packages containing hazardous materials must be secured by enclosing in boxes, cribs or cradles and proper lashing by use of wire rope, strapping or other means, including shoring and bracing, or both. Lashing of deck cargo is permitted if eye pads are used to attach the lashings. Lashings may not be secured to guard rails. Bulky articles must be shored.
(b) A packaging susceptible to weather or water damage must be protected so that it will not be exposed to the weather or to sea water.
(c) Not more than fifty percent of the total open deck area should be used for stowage of hazardous materials (except Class 9 (miscellaneous hazardous material).
(d) Fireplugs, hoses, sounding pipes, and access to these must be free and clear of all cargo.
(e) Crew and passenger spaces and areas set aside for the crew’s use may not be used to stow any hazardous material.
(f) A hazardous material may not be stowed within a horizontal distance of 25 feet of an operating or embarkation point of a lifeboat.
(g) Hazardous materials must be stowed to permit safe access to the crew’s quarters and to all parts of the deck required in navigation and necessary working of the vessel.
(h) When runways for use of the crew are built over stowed hazardous materials, they must be constructed and fitted with rails and lifelines so as to afford complete protection to the crew when in use.
§ 176.76 Transport vehicles, freight containers, and portable tanks containing hazardous materials.
(a) Except as provided in paragraphs (b) through (f) of this section, hazardous materials authorized to be transported by vessel may be carried on board a vessel in a transport vehicle or freight container, subject to the following conditions (see additional requirements concerning the transport of Class 1 (explosive) materials in §§ 176.168 through 176.172 of this subchapter):
(1) The material must be in proper condition for transportation according to the requirements of this subchapter;
(2) All packages in the transport vehicle or freight container must be secured to prevent shifting in any direction. Vertical restraint is not required if the shape of the packages, loading pattern, and horizontal restraint preclude vertical shifting of the load within the freight container or transport vehicle;
(3) Bulkheads made of dunnage which extend to the level of the cargo must be provided unless the packages are stowed flush with the sides or ends;
(4) Dunnage must be secured to the floor when the cargo consists of dense materials or heavy packages;
(5) Each package marked in accordance with § 172.312(a)(2) of this subchapter must be stowed as marked;
(6) Any slack spaces between packages must be filled with dunnage;
(7) The weight in a container must be distributed throughout as evenly as possible and the maximum permissible weight must not be exceeded;
(8) Adjacent levels of baggaged and baled cargo must be stowed in alternate directions so that each tier binds the tier above and below it;
(9) When security devices, beacons or other tracking or monitoring equipment are used, they must be securely installed and must be of a certified safe type for the hazardous materials that will be carried within the freight container or transport vehicle in which such as device or equipment is installed.
(10) The lading must be contained entirely within the freight container or vehicle body without overhang or projection except that oversized machinery such as tractors or vehicles with batteries attached may overhang or project outside the intermodal container provided all of that portion of the lading that consists of hazardous materials is contained entirely within the freight container. No open-bed container or vehicle is permitted to carry hazardous materials unless it is equipped with a means of properly securing the lading.
(11) When packages are secured with banding or straps, these restraints must not be over-tightened to cause damage or deformation of the packages or the securing points (such as D-rings) within the freight container or transport vehicle.
(b) A transport vehicle containing hazardous materials may be carried only on board a trailership, trainship, ferry vessel or car float.
(c) [Reserved]
(d) A transport vehicle or freight container equipped with heating or refrigeration equipment may be operated on board a vessel. However, the equipment may not be operated in any hold or compartment in which any flammable liquid or gas is stowed. Any heating or air conditioning equipment having a fuel tank containing a flammable liquid or gas may be stowed only “on deck”. Equipment electrically powered and designed to operate within an environment containing flammable vapors may be operated below deck in a hold or compartment containing a flammable liquid or gas.
(e) A transport vehicle, loaded with any hazardous material which is required to be stowed “on deck” by § 172.101 of this subchapter, may be stowed one deck below the weather deck when transported on a trainship or trailership which is unable to provide “on deck” stowage because of the vessel’s design. Otherwise, the transport vehicle or container must be transported “on deck.”
(f) A hazardous material may be carried on board a vessel in a portable tank subject to the following conditions:
(1) Small passenger vessels of 100 gross tons, or less, may carry a hazardous material in a portable tank only when 16 or less passengers are on board and only when specifically authorized by the Officer-in-Charge, Marine Inspection, by endorsement of the vessel’s Certificate of Inspection.
(2) Portable tanks containing flammable liquids or gases, combustible liquids with flashpoints below 60 °C (140 °F). that are insoluble in water, or organic peroxides, spontaneously combustible materials, or water reactive materials must be stowed on deck irrespective of the stowage authorized in § 172.101 of this subchapter. Portable tanks containing hazardous materials not restricted to on deck stowage by the previous sentence must be stowed in accordance with the requirements specified in § 172.101 of this subchapter.
(3) Aluminum, magnesium, and their alloys are specifically prohibited as materials of construction of portable tanks.
(g) Cryogenic liquids. For shipment of cryogenic liquids on board a vessel the packaging must be designed and filled so that:

§ 176.77 Stowage of barges containing hazardous materials on board barge-carrying vessels.
(a) A barge which contains hazardous materials may be transported on board a barge-carrying vessel if it is stowed in accordance with the requirements of this section.
(b) A barge which contains hazardous materials for which only “on deck” stowage is authorized must be stowed above the weather deck and be vented to the atmosphere.
(c) A barge which contains hazardous materials for which both “on deck” and “below deck” stowage is authorized may be stowed above or below the weather deck.
§ 176.78 Use of power-operated industrial trucks on board vessels.
(a) Power Operated trucks. A power-operated truck (including a power-operated tractor, forklift, or other specialized truck used for cargo handling) may not be used on board a vessel in a space containing a hazardous material unless the truck conforms to the requirements of this section. The COTP may suspend or prohibit the use of cargo handling vehicles or equipment when that use constitutes a safety hazard.
(b) Each truck must have a specific designation of Underwriter’s Laboratories or Factory Mutual Laboratories. Any repair or alteration to a truck must be equivalent to that required on the original designation.
(c) Description of designations. The recognized testing laboratory type designations are as follows:
(1) An “E” designated unit is an electrically-powered unit that has minimum acceptable safeguards against inherent fire hazards.
(2) An “EE” designated unit is an electrically-powered unit that has, in addition to all the requirements for the “E” unit, the electric motor and all other electrical equipment completely enclosed.
(3) An “EX” designated unit is an electrically-powered unit that differs from the “E” and “EE” unit in that the electrical fittings and equipment are so designed, constructed, and assembled that the unit may be used in certain atmospheres containing flammable vapors or dusts.
(4) A “G” designated unit is a gasoline-powered unit having minimum acceptable safeguards against inherent fire hazards.
(5) A “GS” designated unit is a gasoline-powered unit that is provided with additional safeguards to the exhaust, fuel, and electrical systems.
(6) An “LP” designated unit is similar to a “G” unit except that it is powered by liquefied petroleum gas instead of gasoline.
(7) An “LPS” designated unit is a unit similar to a “GS” unit except that liquefied petroleum gas is used for fuel instead of gasoline.
(8) A “D” designated unit is a unit similar to a “G” unit except that it is powered by a diesel engine instead of a gasoline engine.
(9) A “DS” designated unit is a unit powered by a diesel engine provided with additional safeguards to the exhaust, fuel, and electrical systems.
(d) Class 1 (explosive) materials. No power-operated truck may be used to handle Class 1 (explosive) materials or other cargo in an area near Class 1 (explosive) materials on board a vessel except:
(1) A power-operated truck designated EE or EX.
(2) A power-operated truck designated LPS, GS, D, or DS may be used under conditions acceptable to the COTP.
(e) Other hazardous materials. (1) Only an “EX”, “EE”, “GS”, “LPA”, or “DS” truck may be used in a hold or compartment containing Division 2.1 (flammable gas) materials, Class 3 (flammable liquids), Class 4 (flammable solids) materials, or Class 5 (oxidizers or organic peroxides) materials, cottons or other vegetable fibers, or bulk sulfur.
(2) Only a designated truck may be used to handle any other hazardous material not covered in paragraph (d) or (e)(1) of this section.
(f) Minimum safety features. In addition to the construction and design safety features required, each truck must have at least the following minimum safety features:
(1) The truck must be equipped with a warning horn, whistle, gong, or other device that may be heard clearly above normal shipboard noises.
(2) When the truck operation may expose the operator to danger from a falling object, the truck must be equipped with a driver’s overhead guard. When the overall height of the truck with forks in the lowered position is limited by head room the overhead guard may be omitted. This overhead guard is only intended to offer protection from impact of small packages, boxes, bagged material, or similar hazards.
(3) A forklift truck used to handle small objects or unstable loads must be equipped with a load backrest extension having height, width, and strength sufficient to prevent any load, or part of it, from falling toward the mast when the mast is in a position of maximum backward tilt. The load backrest extension must be constructed in a manner that does not interfere with good visibility.
(4) The forks on a fork lift truck must be secured to the carriage so as to prevent any unintentional lifting of the toe which could create a hazard. The forks may not display permanent deformation when subjected to a test load of three times the rated capacity.
(5) Each fork extension or other attachment must be secured to prevent unintentional lifting or displacement on primary forks.
(6) Tires extending beyond the confines of the truck shall be provided with a guard to prevent the tires from throwing particles at the operator.
(7) Unless the steering mechanism is a type that prevents road reactions from causing the steering handwheel to spin, a mushroom type steering knob must be used to engage the palm of the operator’s hand, or the steering mechanism must be arranged in some other manner to prevent injury. The knob must be mounted within the perimeter of the wheel.
(8) All steering controls must be confined within the clearnace of the truck or guarded so that moving of the controls will not result in injury to the operator when passing stanchions, obstructions or other.
(g) Special operating conditions. (1) A truck may not be used on board a vessel unless prior notification of its use is given to the master or senior deck officer on board.
(2) Before a truck is operated on board a vessel, it must be in a safe operating condition as determined by the master or senior deck officer on board.
(3) Any truck that emits sparks or flames from the exhaust system must immediately be removed from service and may not be returned to service until the cause of these sparks or flames has been eliminated.
(4)-(5) [Reserved]
(6) All truck motors must be shut off immediately when a breakage or leakage of packages containing flammable liquids or gases, flammable solids, oxidizers, or organic peroxides occurs or is discovered.
(7) The rated capacity of the truck must be posted on the truck at all times in a conspicuous place. This capacity may not be exceeded.
(8) At least one Coast Guard approved marine type size 1 Type B, or UL approved 5BC portable fire extinguisher, or its approved equivalent, must be affixed to the truck in a readily accessible position or must be kept in close proximity, available for immediate use.
(9) The vessel’s fire fighting equipment, both fixed (where installed) and portable, must be kept ready for immediate use in the vicinity of the space being worked.
(h) Refueling. (1) A truck using gasoline as fuel may not be refueled in the hold or on the weather deck of a vessel unless a portable non-spilling fuel handling system of not over five gallons capacity is used. Gasoline may not be transferred to a portable non-spilling fuel handling device on board the vessel.
(2) A truck using liquefied petroleum gas as fuel may not be refueled in the hold or on the weather deck of a vessel unless it is fitted with a removable tank and the hand-operated shutoff valve of the depleted tank is closed. In addition, the motor must be run until it stalls from lack of fuel and then the hand-operated shut off valve closed before the quick disconnect fitting to the fuel tank is disconnected.
(3) A truck using diesel oil as fuel may not be refueled on the weather deck or in the hold of a vessel unless a portable container of not over a five gallon capacity is used. A truck may be refueled or a portable container may be refilled from a larger container of diesel fuel on the weather deck of a vessel if a suitable pump is used for the transfer operation and a drip pan of adequate size is used to prevent any dripping of fuel on the deck.
(4) Refueling must be performed under the direct supervision of an experienced and responsible person specifically designated for this duty by the person in charge of the loading or unloading of the vessel.
(5) Refueling may not be undertaken with less than two persons specifically assigned and present for the complete operation, at least one of whom must be experienced in using the portable fire extinguishers required in the fuel area.
(6) At least one Coast Guard approved marine type size 1 Type B or UL approved 5BC portable fire extinguisher or its approved equivalent, must be provided in the fueling area. This is in addition to the extinguisher required by paragraph (g)(8) of this section.
(7) The location for refueling trucks must be designated by the master or senior deck officer on board the vessel. “NO SMOKING” signs must be conspicuously posted in the area.
(8) The location designated for refueling must be adequately ventilated to insure against accumulation of any hazardous concentration of vapors.
(9) Before any truck in a hold is refueled or before any fuel handling device or unmounted liquefied petroleum gas cylinder is placed in a hold, the motors of all trucks in the same hold must be stopped.
(10) All fuel handling devices and unmounted liquefied petroleum gas containers must be removed from a hold before any truck motor is started and the trucks are placed in operation in that hold.
(i) Replacing batteries. Batteries for electrically powered trucks and for the ignition systems of internal combustion powered trucks may be changed in the hold of a vessel subject to the following conditions:
(1) Only suitable handling equipment may be employed.
(2) Adequate precautions must be taken to avoid damage to the battery, short circuiting of the battery, and spillage of the electrolyte.
(j) Charging of batteries. Batteries of industrial trucks may be recharged in a hold of a vessel subject to the following conditions:
(1) The batteries must be housed in a suitable, ventilated, portable metal container with a suitable outlet at the top for connection of a portable air hose, or must be placed directly beneath a suitable outlet at the top for connection of a portable air hose. The air hose must be permanently connected to an exhaust duct leading to the open deck and terminate in a gooseneck or other suitable weather head. If natural ventilation is not practicable or adequate, mechanical means of exhaust must be employed in conjunction with the duct. The air outlet on the battery container must be equipped with an interlock switch so arranged that the charging of the battery cannot take place unless the air hose is properly connected to the box.
(2) If mechanical ventilation is used, an additional interlock must be provided between the fan and the charging circuit so that the fan must be in operation in order to complete the charging circuit for operation. It is preferable that this interlock switch be of a centrifugal type driven by the fan shaft.
(3) The hold may not contain any hazardous materials.
(4) The charging facilities may be part of the truck equipment or may be separate from the truck and located inside or outside the cargo hold. The power supply or charging circuit (whichever method is used) must be connected to the truck by a portable plug connection of the break-away type. This portable plug must be so engaged with the truck battery charging outlet that any movement of the truck away from the charging station will break the connection between the plug and receptacle without exposing any live parts to contact with a conducting surface or object and without the plug falling to the deck where it may become subject to damage.
(5) All unmounted batteries must be suitably protected or removed from an area in the hold of the vessel before any truck is operated in that area.
(k) Stowage of power-operated industrial trucks on board a vessel. Trucks stowed on board a vessel must meet vessel stowage requirements in § 176.905.
(l) Packaging and stowage of fuel on board a vessel. Division 2.1 (flammable gas) materials and flammable liquids used as fuel for industrial trucks must be packaged and stowed as authorized in 46 CFR 147.60 or 46 CFR 147.45, respectively.
Subpart D – General Segregation Requirements
§ 176.80 Applicability.
(a) This subpart sets forth segregation requirements in addition to any segregation requirements set forth elsewhere in this subchapter.
(b) Hazardous materials in limited quantities when loaded in transport vehicles and freight containers, are excepted from the segregation requirements of this subpart and any additional segregation specified in this subchapter for transportation by vessel; except that articles of division 1.4, compatibility group S, shall not be stowed in the same compartment or hold, or cargo transport unit with hazardous materials of Class 1 of compatibility groups A and L.
§ 176.83 Segregation.
(a) General. (1) The requirements of this section apply to all cargo spaces on deck or under deck of all types of vessels, and to all cargo transport units.
(2) Segregation is obtained by maintaining certain distances between incompatible hazardous materials or by requiring the presence of one or more steel bulkheads or decks between them or a combination thereof. Intervening spaces between such hazardous materials may be filled with other cargo which is not incompatible with the hazardous materials.
(3) The general requirements for segregation between the various classes of dangerous goods are shown in the segregation table. In addition to these general requirements, there may be a need to segregate a particular material from other materials which would contribute to its hazard. Such segregation requirements are indicated by code numbers in Column 10B of the § 172.101 Table.
(4) Segregation is not required:
(i) Between hazardous materials of different classes which comprise the same substance but vary only in their water content (for example, sodium sulfide in Division 4.2 or Class 8) or quantity for Class 7 materials; or
(ii) Between hazardous materials of different classes which comprise a group of substances that do not react dangerously with each other. The following materials are grouped by compatibility:
(A) Hydrogen peroxide, aqueous solutions with not less than 8 percent but less than 20 percent hydrogen peroxide (stabilized as necessary); Hydrogen peroxide, aqueous solutions with not less than 20 percent but not more than 40 percent hydrogen peroxide; Hydrogen peroxide, aqueous solutions with more than 40 percent but not more than 60 percent hydrogen peroxide; Hydrogen peroxide and peroxyacetic acid mixtures, stabilized with acids, water and not more than 5 percent peroxyacetic acid; Organic peroxide type D, liquid; Organic peroxide type E, liquid; Organic peroxide type F, liquid;
(B) Dichlorosilane, Silicon tetrachloride, and Trichlorosilane; and
(C) Organometallic substance, solid, pyrophoric; Organometallic substance, liquid, pyrophoric; Organometallic substance, solid, pyrophoric, water-reactive; Organometallic substance, liquid, pyrophoric, water-reactive; Organometallic substance, solid, water-reactive; Organometallic substance, solid, water-reactive, flammable; Organometallic substance, solid, water-reactive, self-heating; Organometallic substance, liquid, water-reactive; Organometallic substance, liquid, water-reactive, flammable; and Organometallic substance, solid, self-heating.
(5) Whenever hazardous materials are stowed together, whether or not in a cargo transport unit, the segregation of such hazardous materials from others must always be in accordance with the most restrictive requirements for any of the hazardous materials concerned.
(6) When the § 172.101 Table or § 172.402 requires packages to bear a subsidiary hazard label or labels, the segregation appropriate to the subsidiary hazards must be applied when that segregation is more restrictive than that required by the primary hazard. For the purposes of this paragraph, the segregation requirements corresponding to an explosive subsidiary hazard are – except for organic peroxides which are those corresponding to Division 1.3 – those for Division 1.4 (explosive) materials.
(7) Where, for the purposes of segregation, terms such as “away from” a particular hazard class are used in the § 172.101 Table, the segregation requirement applies to:
(i) All hazardous materials within the hazard class; and
(ii) All hazardous materials for which a secondary hazard label of that class is required.
(8) Notwithstanding the requirements of paragraphs (a)(6) and (a)(7) of this section, hazardous materials of the same class may be stowed together without regard to segregation required by secondary hazards (subsidiary risk label(s)), provided the substances do not react dangerously with each other and cause:
(i) Combustion and/or evolution of considerable heat;
(ii) Evolution of flammable, toxic or asphyxiant gases;
(iii) The formation of corrosive substances; or
(iv) The formation of unstable substances.
(9) Stowage in a shelter-‘tween deck cargo space is not considered to be “on deck” stowage.
(10) Where the code in column (10B) of the § 172.101 Table specifies that “Segregation as for. . .” applies, the segregation requirements applicable to that class in the § 176.83(b) General Segregation Table must be applied. However, for the purposes of paragraph (a)(8) of this section, which permits substances of the same class to be stowed together provided they do not react dangerously with each other, the segregation requirements of the class as represented by the primary hazard class in the § 172.101 Table entry must be applied.
(11) Certain exceptions from segregation for waste cyanides or waste cyanide mixtures or solutions transported with acids; waste Division 4.2 materials transported with Class 8 liquids; and waste Division 6.1 Packing Group I, Hazard Zone A material transported with waste Class 3 material, Class 8 liquids, and Division 4.1, 4.2, 4.3, 5.1 or 5.2 material are set forth in § 173.12(e) of this subchapter.
(b) General Segregation Table. The following table sets forth the general requirements for segregation between the various classes (divisions) of hazardous materials. Certain divisions are listed as separate hazard classes for the purpose of this table (e.g., “2.1” and “2.2”). The properties of materials within each class may vary greatly and may require greater segregation than is reflected in this table. If the § 172.101 Table sets forth particular requirements for segregation, they take precedence over these general requirements.
Table 176.83(
[Segregation must also take account of a single secondary hazard label, as required by paragraph (a)(6) of this section.]

Numbers and symbols relate to the following terms as defined in this section:
1 – “Away from.”
2 – “Separated from.”
3 – “Separated by a complete compartment or hold from.”
4 – “Separated longitudinally by an intervening complete compartment or hold from.”
X – The segregation, if any, is shown in the § 172.101 table.
* – See § 176.144 of this part for segregation within Class 1.
(c) Segregation requirements for breakbulk cargo. (1) The requirements of this paragraph apply to the segregation of packages containing hazardous materials and stowed as breakbulk cargo;
(2) Definition of the segregation terms:
(i) Legend:
(A) Package containing incompatible goods.
(B) Reference package.
(C) Deck resistant to fire and liquid.
Full vertical lines represent transverse bulkheads between compartments or holds resistant to fire and liquid.
(ii) “Away from”: Effectively segregated so that the incompatible materials cannot interact dangerously in the event of an accident but may be carried in the same compartment or hold or on deck provided a minimum horizontal separation of 3 m (10 feet) projected vertically is obtained.
(iii) “Separated From”: In different compartments or holds when stowed under deck. If the intervening deck is resistant to fire and liquid, a vertical separation (i.e., in different compartments) is acceptable as equivalent to this segregation. For “on deck” stowage, this segregation means a separation by a distance of at least 6 m (20 feet) horizontally.
(iv) “Separated by a complete compartment or hold from”: Either a vertical or horizontal separation. If the intervening decks are not resistant to fire and liquid, then only a longitudinal separation (i.e., by an intervening complete compartment or hold) is acceptable. For “on deck” stowage, this segregation means a separation by a distance of at least 12 m (39 feet) horizontally. The same distance must be applied if one package is stowed “on deck”, and the other one in an upper compartment.
One of the two decks must be resistant to fire and liquid.
(v) “Separated longitudinally by an intervening complete compartment or hold from”: Vertical separation alone does not meet this requirement. Between a package “under deck” and one “on deck” a minimum distance of 24 m (79 feet) including a complete compartment must be maintained longitudinally. For “on deck” stowage, this segregation means a separation by a distance of at least 24 m (79 feet) longitudinally.
(d) Segregation in cargo transport units: Two hazardous materials for which any segregation is required may not be stowed in the same cargo transport unit.
(e) Segregation of hazardous materials stowed as breakbulk cargo from those packed in cargo transport units: (1) Hazardous materials stowed as breakbulk cargo must be segregated from materials packed in open cargo transport units in accordance with paragraph (c) of this section.
(2) Hazardous materials stowed as breakbulk cargo must be segregated from materials packed in closed cargo transport units in accordance with paragraph (c) of this section, except that:
(i) Where “away from” is required, no segregation between packages and the closed cargo transport units is required; and
(ii) Where “separated from” is required, the segregation between the packages and the closed cargo transport units may be the same as for “away from”.
(f) Segregation of cargo transport units on board container vessels: (1) Except for hatchless container ships, this paragraph applies to segregation of cargo transport units that are carried on board container vessels, or on other types of vessels, provided these cargo spaces are properly fitted for permanent stowage of containers during transport.
(2) For container vessels which have cargo spaces used for breakbulk cargo or any other method of stowage, the appropriate paragraph of this section applies to the relevant cargo space.
(3) Segregation Table. Table § 176.83(f) sets forth the general requirements for segregation between cargo transport units on board container vessels.
(4) In table § 176.83(f), a container space means a distance of not less than 6 m (20 feet) fore and aft or not less than 2.5 m (8 feet) athwartship.

(h) Segregation on board barge carrying vessels: (1) The requirements of this section apply to the segregation in shipborne barges as well as to the segregation between shipborne barges carried on board vessels specially designed and equipped to carry such barges.
(2) On barge-carrying vessels which incorporate other stowage spaces or any other method of stowage, barges containing hazardous materials must be segregated from hazardous materials not stowed in barges as prescribed in paragraphs (b) and (j) of this section.
(i) Segregation in shipborne barges: Hazardous materials transported in shipborne barges must be segregated as prescribed in paragraphs (a), (b), and (c) of this section.
(j) Segregation between shipborne barges on barge-carrying vessels: (1) When a shipborne barge is loaded with two or more hazardous materials with different requirements for segregation, the most stringent applicable segregation requirement must be applied.
(2) “Away from” and “separated from” require no segregation between shipborne barges.
(3) For barge-carrying vessels with vertical holds, “Separated by a complete compartment or hold from” means that separate holds are required. On barge-carrying vessels having horizontal barge levels, separate barge levels are required and the barges may not be in the same vertical line.
(4) “Separated longitudinally by an intervening complete compartment or hold from” means, for barge-carrying vessels with vertical holds, that separation by an intervening hold or engine room is required. On barge-carrying vessels having horizontal barge levels, separate barge levels and a longitudinal separation by at least two intervening barge spaces are required.
(k) Segregation requirements for ferry vessels: A ferry vessel (when operating either as a passenger or cargo vessel) that cannot provide the separation required in this section may carry incompatible hazardous materials in separate transport vehicles if they are stowed to give the maximum possible separation.
(l) Segregation of containers on board hatchless (open-top) container ships: (1) This paragraph applies to the segregation of cargo transport units that are transported on board hatchless container ships provided that the cargo spaces are properly fitted to give permanent stowage of the cargo transport units during transport.
(2) For container ships that have both hatchless container spaces and other spaces suitable for breakbulk cargo, conventional container stowage, or any other method of stowage, the appropriate requirements of this section apply to the relevant cargo space.
(3) Segregation Table. Table § 176.83(l)(3) sets forth the general requirements for segregation of cargo transport units on board hatchless container ships.
(4) In Table § 176.83(l)(3), a container space means a distance of not less than 6 m (20 feet) fore and aft or not less than 2.5 m (8 feet) athwartship.

(m) Provisions for segregation groups: (1) For the purpose of segregation, materials having certain similar chemical properties have been grouped together in segregation groups. The segregation groups (such as “acids”, “chlorates”, “permanganates”) and the entries allocated to each of these groups include the substances identified in section 3.1.4 of the IMDG Code (IBR, see § 171.7 of this subchapter). When column (10B) of the § 172.101 Table refers to a numbered stowage provision set forth in § 176.84(b) such as “Stow ‘away from’ acids”, that particular stowage/segregation requirement applies to all the materials allocated to the respective segregation group.
(2) Not all hazardous materials falling within a segregation group are listed by name in the regulations. These materials are shipped under “n.o.s.” entries. Although these “n.o.s.” entries are not listed themselves in the above groups, the person who offers a hazardous material for transportation must decide whether allocation under a segregation group is appropriate.
(3) The segregation groups described above do not address materials that fall outside the classification criteria of the hazardous materials regulations, although it is recognized that some non-hazardous materials have certain chemical properties similar to hazardous materials listed in the segregation groups. A person who offers a hazardous material for transportation or the person responsible for packing the materials into a cargo transport unit who does have knowledge of the chemical properties of such non-hazardous materials may identify a relevant segregation group and apply the segregation requirements for that segregation group.
§ 176.84 Other requirements for stowage, cargo handling, and segregation for cargo vessels and passenger vessels.
(a) General. When Column 10B of the § 172.101 Table refers to a numbered or alpha-numeric stowage provision for water shipments, the meaning and requirements of that provision are set forth in this section. Terms in quotation marks are defined in § 176.83. Other terms used in the table in this section such as “acids”, “chlorates” and “permanganates” indicate different chemical groups referred to here as segregation groups. Materials falling within a segregation group are considered to have certain similar chemical properties and, although not exhaustive in nature, the materials belonging to each group include those substances identified in section 3.1.4 of the IMDG Code (IBR, see § 171.7 of this subchapter) as set forth in § 176.83(m).

Unless the engine of a cargo tank motor vehicle is to be used for the operation of a pump, Class 3 material may not be loaded into, or on, or unloaded from any cargo tank motor vehicle while the engine is running. The diesel engine of a cargo tank motor vehicle may be left running during the loading and unloading of a Class 3 material if the ambient atmospheric temperature is at or below −12 °C (10 °F).
(b) Bonding and grounding containers other than cargo tanks prior to and during transfer of lading. For containers which are not in metallic contact with each other, either metallic bonds or ground conductors shall be provided for the neutralization of possible static charges prior to and during transfers of Class 3 (flammable liquid) materials between such containers. Such bonding shall be made by first connecting an electric conductor to the container to be filled and subsequently connecting the conductor to the container from which the liquid is to come, and not in any other order. To provide against ignition of vapors by discharge of static electricity, the latter connection shall be made at a point well removed from the opening from which the Class 3 (flammable liquid) material is to be discharged.
(c) Bonding and grounding cargo tanks before and during transfer of lading. (1) When a cargo tank is loaded through an open filling hole, one end of a bond wire shall be connected to the stationary system piping or integrally connected steel framing, and the other end to the shell of the cargo tank to provide a continuous electrical connection. (If bonding is to the framing, it is essential that piping and framing be electrically interconnected.) This connection must be made before any filling hole is opened, and must remain in place until after the last filling hole has been closed. Additional bond wires are not needed around All-Metal flexible or swivel joints, but are required for nonmetallic flexible connections in the stationary system piping. When a cargo tank is unloaded by a suction-piping system through an open filling hole of the cargo tank, electrical continuity shall be maintained from cargo tank to receiving tank.
(2) When a cargo tank is loaded or unloaded through a vapor-tight (not open hole) top or bottom connection, so that there is no release of vapor at a point where a spark could occur, bonding or grounding is not required. Contact of the closed connection must be made before flow starts and must not be broken until after the flow is completed.
(3) Bonding or grounding is not required when a cargo tank is unloaded through a nonvapor-tight connection into a stationary tank provided the metallic filling connection is maintained in contact with the filling hole.

(e) lnstructions for using the segregation table for hazardous materials are as follows:
(1) The absence of any hazard class or division or a blank space in the table indicates that no restrictions apply.
(2) The letter “X” in the table indicates that these materials may not be loaded, transported, or stored together in the same transport vehicle or storage facility during the course of transportation.
(3) The letter “O” in the table indicates that these materials may not be loaded, transported, or stored together in the same transport vehicle or storage facility during the course of transportation unless separated in a manner that, in the event of leakage from packages under conditions normally incident to transportation, commingling of hazardous materials would not occur. Notwithstanding the methods of separation employed, Class 8 (corrosive) liquids may not be loaded above or adjacent to Class 4 (flammable) or Class 5 (oxidizing) materials; except that shippers may load truckload shipments of such materials together when it is known that the mixture of contents would not cause a fire or a dangerous evolution of heat or gas.
(4) The “*” in the table indicates that segregation among different Class 1 (explosive) materials is governed by the compatibility table in paragraph (f) of this section.
(5) The note “A” in the second column of the table means that, notwithstanding the requirements of the letter “X”, ammonium nitrate (UN1942) and ammonium nitrate fertilizer may be loaded or stored with Division 1.1 (explosive) or Division 1.5 materials, unless otherwise prohibited by § 177.835(c).
(6) When the § 172.101 table or § 172.402 of this subchapter requires a package to bear a subsidiary hazard label, segregation appropriate to the subsidiary hazard must be applied when that segregation is more restrictive than that required by the primary hazard. However, hazardous materials of the same class may be stowed together without regard to segregation required for any secondary hazard if the materials are not capable of reacting dangerously with each other and causing combustion or dangerous evolution of heat, evolution of flammable, poisonous, or asphyxiant gases, or formation of corrosive or unstable materials.
(f) Class 1 (explosive) materials shall not be loaded, transported, or stored together, except as provided in this section, and in accordance with the following table:
