NFPA lists _____ as the standard for identifying chemical hazards of materials at fixed facilities.

• A. 210
• B. 704
• C. 704A
• D. 101

Answer: (B)

Understanding how NFPA hazard identification works helps you see why this is the standard used at fixed facilities. The NFPA 704 system is the familiar diamond that communicates hazards at a glance through four fields: health, flammability, reactivity, and a separate area for special hazards. Each field uses a 0–4 rating to indicate how severe the hazard is, so responders and facility workers can quickly gauge risk and determine needed protective actions, isolation, and response steps. For identifying chemical hazards specifically at fixed facilities, NFPA 704 is the standard typically referenced, because it provides the concise, at-a-glance guidance that facilities rely on. The other NFPA standards cover different topics (such as life safety in buildings) or are not the primary hazard-labeling tool used in fixed-facility contexts, which is why NFPA 704 is the best fit.
