Not sure where to begin a search for a packaging reference in 49CFR? The CFR (Code of Federal Regulations) is the Hazardous Materials shipping bible. In Title 49, there are definitions, classifications, regulations and a host of specific requirements set forth by the US DOT regarding the safe transport of hazardous materials by air, rail, water or road. Subtitle B of Chapter 1 refers to the Research and Special Programs Administration, with Subchapters A — C targeting Hazardous Materials Transportation Pipeline Safety, Oil Transportation, and Hazardous Materials Regulations. These subchapters are divided into Parts 171-180 with Subparts, Sections, Paragraphs and Subparagraphs. Part 178 addresses Hazardous Materials Packaging Specifications.
Finding a particular reference to a regulatory question can be difficult. For several years, Skolnik has been developing a CFR Cheat-Sheet of specific paragraphs that speak to common questions regarding UN (United Nations) packagings. A part of the Skolnik web site, the CFR Cheat-Sheet lists, and links, to about 50 packaging references and the exact paragraph that explains the regulatory requirement. The Cheat-Sheet primarily focuses on Section 49 of the CFR, and requirements mostly applicable to steel and plastic drums of all sizes.
