Which system is used to identify the flammability of a hazmat material during recognition?

• A. OSHA hazard labeling system
• B. NFPA 704 system
• C. DOT labeling scheme
• D. ISO hazard scale

Answer: (B)

NFPA 704, often seen as the fire diamond, is the system used to identify the flammability of hazmat materials during recognition. On containers, the red section of the diamond rates flammability from 0 to 4, with higher numbers signaling greater ignition risk. This compact, at-a-glance labeling lets responders quickly assess how easily a material can ignite and plan protective actions and response steps accordingly, without needing to consult detailed documents. The blue and yellow sections show health and reactivity hazards, and the white section notes any special hazards, giving a quick, overall picture of the material’s dangers. Other labeling schemes exist for labeling and shipping contexts, but NFPA 704 is specifically designed for fast recognition of hazard severity in the field.
