摘要总结AI 辅助解读

该条款规定了美国运输部（DOT）对自燃固体、金属或合金（n.o.s.）的危险品包装要求。此类材料必须符合49 CFR Part 178中指定的包装组性能等级，并严格采用特定类型的容器包装，包括钢/铝/其他金属箱、带内衬金属容器的木箱或纤维板箱、以及特定规格的金属桶等。不同包装形式对应不同的最大净重限制（如金属箱限15kg，纤维板箱内衬限7.5kg），且所有内衬金属容器必须具备防止因运输震动导致盖子松脱的闭合机制。此外，也允许使用除Spec 8和3HT外的压缩气体规格气瓶。

Packagings for pyrophoric solids, metals, or alloys, n.o.s. must conform to the requirements of part 178 of this subchapter at the packing group performance level specified in the § 172.101 Table. These materials must be packaged as follows:

(a) In steel, aluminum or other metal boxes (4A, 4B or 4N) and contain no more than 15 kg (33 pounds) each.
(b) In wooden boxes (4C1, 4C2, 4D, or 4F) with inner metal receptacles that have threaded closures or alternate closures physically held in place by a means capable of preventing back-off or loosening of the closure due to conditions normally incident to transportation ( e.g., impact, vibration, etc.). Each inner metal receptacle must not contain more than 15 kg (33 pounds).
(c) In fiberboard boxes (4G) with inner metal receptacles that have threaded closures or alternate closures physically held in place by a means capable of preventing back-off or loosening of the closure due to conditions normally incident to transportation ( e.g., impact, vibration, etc.). Each inner metal receptacle must not contain more than 7.5 kg (17 pounds).
(d) In steel, aluminum or other metal drums (1A1, 1A2, 1B1, 1B2, 1N1 or 1N2) with a gross mass not exceeding 150 kg (331 pounds) per drum.
(e) In plywood drums (1D) with inner metal receptacles that have threaded closures or alternate closures physically held in place by a means capable of preventing back-off or loosening of the closure due to conditions normally incident to transportation ( e.g., impact, vibration, etc.). Each inner metal receptacle must not contain more than 15 kg (33 pounds).
(f) In fiberboard drums (1G) with inner metal receptacles that have threaded closures or alternate closures physically held in place by a means capable of preventing back-off or loosening of the closure due to conditions normally incident to transportation ( e.g., impact, vibration, etc.) Each inner metal receptacle must not contain more than 15 kg (33 pounds).
(g) In specification cylinders, as prescribed for any compressed gas, except for Specifications 8 and 3HT.
