Which section addresses guidelines against tampering with hazardous materials packaging?

The choice that accurately identifies the section addressing guidelines against tampering with hazardous materials packaging is found within the larger framework of regulations under the Code of Federal Regulations (CFR). The CFR encompasses numerous regulations that relate to the handling, transportation, and storage of hazardous materials. Specifically, it includes provisions that prohibit tampering with materials that are deemed hazardous, thereby ensuring safety and compliance in industry practices.

This choice is appropriate because regulations under the CFR provide a comprehensive set of rules that govern safe practices and responsibilities for handling hazardous materials, including preventing actions that could compromise the integrity of packaging. While other choices refer to specific sections or associated regulations, the reference to regulations under the CFR captures the broader regulatory framework that includes these important safety guidelines.

In contrast, while HMTA §5104 (the Hazardous Materials Transportation Act) and 49 CFR part 1572 pertain to hazardous materials transportation and security, they do not specifically focus on tampering with packaging. Similarly, general Occupational Safety regulations encompass workplace safety practices but may not directly address the specific issue of tampering with hazardous materials packaging. Hence, the broader context of regulations under the CFR is most relevant to this question.
