Which NFPA color indicates specific hazard?

• A. Blue
• B. Red
• C. White
• D. Yellow

Answer: (C)

NFPA 704 uses a diamond split into four color fields. Each color communicates a different aspect of hazard: blue for health, red for flammability, and yellow for reactivity. The white field is set aside for special or specific hazards that don’t fit into those three categories. That’s why white indicates a specific hazard—and what you’ll see in that space (like OX for oxidizers, COR for corrosives, or W with a line for water reactivity) tells you the exact special condition you must account for when planning protective actions.
