本法规规定含毒性物质的气体鉴定套装（Gas identification sets）在美国运输时的包装要求。此类物品必须按照49 CFR Part 178中I级包装组（Packing Group I）标准进行包装。具体分为两种情形：一是玻璃内衬容器需密封并置于纤维板容器中，再装入4G纸箱及钢瓶；二是当毒性物质被活性炭等介质吸收时，根据液体或固体的量（不超过5mL/5g或20g），可采用不同规格的玻璃瓶、金属罐或塑料盒组合包装，并严格限制外层箱体内的总含量（如不超过100mL或100g）。该条款旨在确保危险品在运输过程中的防泄漏与防护安全。

Gas identification sets containing poisonous material must be packaged in packagings conforming to the requirements of part 178 of this subchapter at the Packing Group I performance level, as follows:

(a) In glass inner receptacles, hermetically sealed, of not over 40 mL (1.4 fluid ounces) each. Each glass inner receptacle must in turn be placed in a sealed fiberboard receptacle, cushioned with absorbent material. Not more than 12 fiberboard receptacles must in turn be placed in a 4G fiberboard box. No more than four boxes, well-cushioned, may in turn be placed in a steel cylinder. The cylinder must have a wall thickness of at least 3.7 mm (0.146 inch) and must have a hermetically sealed steel closure.
(b) When the poisonous material is absorbed in a medium such as activated charcoal or silical gel, gas identification sets may be shipped as follows:

- (1) If the poisonous material does not exceed 5 mL (0.2 fluid ounce) if a liquid or 5 g (0.2 ounce) if a solid, it may be packed in glass inner receptacles of not over 120 mL (4.1 fluid ounces) each. Each glass receptacle, cushioned with absorbent material must be packed in a hermetically sealed metal can of not less than 0.30 mm (0.012 inch) wall thickness. Metal cans, surrounded on all sides by at least 25 mm (1 inch) of dry sawdust, must be packed in 4A, 4B or 4N metal boxes or 4C1, 4C2, 4D or 4F wooden boxes. Not more than 100 mL (3.4 fluid ounces) or 100 g (3.5 ounces) of poisonous materials may be packed in one outer box.

- (2) If the poisonous material does not exceed 5 mL (0.2 fluid ounce) if a liquid or 20 g (0.7 ounce) if a solid, it may be packed in glass inner receptacles with screw-top closures of not less than 60 mL (2 fluid ounces), hermetically sealed. Twelve bottles containing poisonous material, not to exceed 100 mL (3.4 fluid ounces) or 100 g (3.5 ounces), or both, may be placed in a plastic carrying case, each glass receptacle surrounded by absorbent cushioning and each separated from the other by sponge rubber partitions. The plastic carrying case must be placed in a tightly fitting fiberboard box which in turn must be placed in a tightly fitting 4A, 4B or 4N metal box or 4C1, 4C2, 4D or 4F wooden box.
