Which part of the 49 CFR covers packaging specifications and testing?

• A. Part 173
• B. Part 178 (Packaging) with related sections in Part 173
• C. Part 171
• D. Part 172

Answer: (B)

Packaging specifications and testing in the 49 CFR are set by Part 178, which establishes general packaging requirements and the tests that packaging must pass to be used for hazardous materials shipments. Part 173 provides the specific packing instructions and test methods for particular materials, so complying with both Part 178 and the relevant sections of Part 173 ensures the packaging meets the required standards. The other parts cover different areas: Part 171 deals with general administrative rules, and Part 172 handles hazard communication, shipping papers, labeling, and related requirements. Therefore, the combination of Part 178 with the applicable sections in Part 173 is the proper framework for packaging specifications and testing.
