49 CFR 176.144 - Segregation of Class 1 (explosive) materials. | Title 49 - Transportation | Code of Federal Regulations

§ 176.144

Segregation of Class 1 (explosive) materials.

(a) Except as provided in § 176.145 of this subchapter, stowage of Class 1 (explosive) materials within the same compartment, magazine, or cargo transport unit is subject to provisions contained in table 176.144(a).

[An “X” indicates that explosives in the two different compatibility groups reflected by the location of the “X” may not be stowed in the same compartment, magazine, or cargo transport unit]

Notes: 1. Explosive articles in compatibility group G, other than fireworks and those requiring special stowage, may be stowed with articles of compatibility groups C, D, and E, provided no explosive substances are carried in the same compartment, magazine or cargo transport unit.
2. Explosives in compatibility group L may only be stowed in the same compartment, magazine or cargo transport unit with identical explosives within compatibility group L.
3. Different types of articles of Division 1.6, compatibility group N, may only be transported together when it is proven that there is no additional risk of sympathetic detonation between the articles. Otherwise they must be treated as division 1.1.
4. When articles of compatibility group N are transported with articles or substances of compatibility groups C, D or E, the goods of compatibility group N must be treated as compatibility group D.
5. When articles of compatibility group N are transported together with articles or substances of compatibility group S, the entire load must be treated as compatibility group N.
6. Any combination of articles in compatibility groups C, D and E must be treated as compatibility group E. Any combination of substances in compatibility groups C and D must be treated as the most appropriate compatibility group shown in Table 2 of § 173.52 taking into account the predominant characteristics of the combined load. This overall classification code must be displayed on any label or placard on a unit load or cargo transport unit as prescribed in subpart E (Labeling) and subpart F (Placarding).

(b) Where Class 1 (explosive) materials of different compatibility groups are allowed to be stowed in the same compartment, magazine, or cargo transport unit, the stowage arrangements must conform to the most stringent requirements for the entire load.

(c) Where a mixed load of Class 1 (explosive) materials of different hazard divisions and/or stowage arrangements is carried within a compartment, magazine, or cargo transport unit, the entire load must be treated as belonging to the hazard division having the greatest hazard. (For example, if a load of Division 1.1 (explosive) materials is mixed with Division 1.3 (explosive) materials, the load is treated as a Division 1.1 (explosive) material as defined in § 173.50(b) of this subchapter and the stowage must conform to the most stringent requirements for the entire load).

(d) If some of the Class 1 (explosive) materials in a stowage mixture require magazine stowage, Class 1 (explosive) materials requiring ordinary stowage may be stowed in the same magazine. When the magazine is used for substances requiring Type A stowage, the other Class 1 (explosive) materials stowed therein must have no exposed parts of any ferrous metal or aluminum alloy, unless separated by a partition.

(e) Segregation on deck: When Class 1 (explosive) materials in different compatibility groups are carried on deck, they must be stored not less than 6 m (20 feet) apart unless they are allowed under Table 176.144(a) to be stowed in the same compartment, magazine, or cargo transport unit.

(f) On a barge used to transfer class 1 (explosive) materials from a waterfront facility to a vessel at an explosives anchorage (or from the vessel to the water front facility), if compliance with paragraph (e) of this section is not practicable, a sandbag barrier at least 0.6 m (2 feet) in thickness may be substituted for the 6 m (20 feet) separation.

Summary

PHMSA is amending the Hazardous Materials Regulations in response to petitions for rulemaking submitted by the regulated community to update, clarify, or provide relief from miscellaneous regulatory requirements. Specifically, PHMSA is amending the recordkeeping and package marking requirements for third-party labs and manufacturers to assure the traceability of packaging; removing the listing for “NA1203, Gasohol, gasoline mixed with ethyl alcohol, with not more than 10% alcohol”; harmonizing internationally and providing a limited quantity exception for Division 4.1, Self-reactive solids and Self-reactive liquids Types B through F; allowing smokeless powder classified as a Division 1.4C material to be reclassified as a Division 4.1 material; and providing greater flexibility by allowing the Dangerous Cargo Manifest to be in locations designated by the master of the vessel besides “on or near the vessel's bridge” while the vessel is in a United States port.

Summary

This document responds to administrative appeals generated as a result of certain amendments adopted in an international harmonization final rule published on January 19, 2011. The January 19, 2011 final rule amended the Hazardous Materials Regulations (HMR) by revising, removing or adding proper shipping names, the hazard class of a material, packing group assignments, special provisions, packaging authorizations, packaging sections, air transport quantity limitations, and vessel stowage requirements. The amendments were necessary to align the HMR with recent revisions to international standards for the transport of hazardous materials by all modes. In this final rule, PHMSA amends the HMR as a result of administrative appeals submitted in response to various amendments adopted in the January 19, 2011 final rule. This document also addresses recent actions taken by the International Civil Aviation Organization's (ICAO) Dangerous Goods Panel (DGP) regarding certain lithium ion battery-powered mobility aids (e.g., wheelchairs, travel scooters) offered by passengers for air transport and passenger notification of hazardous materials restrictions by operators. Further, this final rule adopts amendments to the HMR as a result of two administrative appeals submitted by an appellant in response to a final rule published February 2, 2010, that revised shipper responsibilities related to packaging design variation, manufacturer notification, and recordkeeping requirements for certain packaging types.
