Which of the following is NOT considered a source of hazard information?

The Code of Federal Regulations (CFR) is primarily a collection of rules published by the executive departments and agencies of the United States federal government. While the CFR outlines regulations, standards, and legal obligations, it is not primarily a source of hazard information in the same way that other options such as facility documents, reference manuals, or technical information centers are.

Facility documents typically provide specific data about hazardous materials used or stored onsite, including safety data sheets (SDS) that outline necessary safety precautions and emergency measures. Reference manuals serve as comprehensive guides that include detailed information on handling hazardous substances, safety protocols, and emergency response techniques. Technical information centers offer access to specialized knowledge and expert advice on hazardous materials, often allowing responders to assess hazards in real time.

In contrast, the CFR serves more as a regulatory framework and compliance standard rather than a direct source of hazard information. Thus, identifying the CFR as the option that does not constitute a source of hazard information is accurate within the context of this question.
