Hazard ratings are defined in which US transportation regulation?

• A. 29 CFR
• B. 49 CFR
• C. 14 CFR
• D. 7 CFR

Answer: (B)

Hazard ratings for transporting hazardous materials come from the regulation that handles the Hazardous Materials Regulations (HMR) under the Department of Transportation. This part of the code, codified as 49 CFR, defines how materials are classified by hazard class and packing group, and how they must be labeled, packaged, documented, and handled during transport. In practice, the hazard class and packing group determine the specific shipping requirements and risk communication for a given material. The other regulations address different areas: 29 CFR covers OSHA workplace safety rules, 14 CFR governs aviation rules, and 7 CFR relates to agricultural regulations.
