Placard color white indicates which hazard?

• A. Flammable
• B. Health Hazard
• C. Explosive
• D. Oxidizer Reactive

Answer: (B)

The white portion of an NFPA 704 placard shows special hazards, not a specific hazard class. It’s used to convey additional handling information (often symbols or letters like W for water-reactive or OX for oxidizers). The blue section indicates health hazard, red indicates flammability, and yellow indicates reactivity or oxidizer properties. Because white is reserved for these special hazard notes, it does not denote a standard hazard category like health hazard.
