Which color on facility placards represents special hazards?

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

Answer: (D)

Special hazards are identified in the white portion of the NFPA 704 placard. The blue, red, and yellow sections convey health, flammability, and reactivity risk, respectively, but the white area is reserved for any specific or “special” hazards (like oxidizers, water-reactive materials, or acids/alkalis). This white label tells responders there are additional precautions beyond the standard categories—for example, avoid water with water‑reactive substances or follow specific handling instructions indicated by symbols like OX or W. So the color representing special hazards is the white section, since it flags these unique cautions that require tailored responses.
