What does a white placard indicate?

• A. Special hazards with symbols
• B. Temperature hazards
• C. Flammable hazard
• D. Environmental hazards

Answer: (A)

In the NFPA 704 hazard diamond, the white section is reserved for special hazards with symbols. This area is used to convey additional risk information (such as oxidizers or water-reactive materials) that isn’t captured by the blue, red, or yellow sections. Seeing a white placard indicates there are these special hazards requiring particular handling beyond the standard health, flammability, and reactivity ratings. The other concepts—temperature hazards or environmental hazards—aren’t conveyed by the white panel alone, and flammability is shown by the red section rather than the white.
