The white quadrant in the 6 o'clock position of the NFPA 704 system is used to indicate:

• A. Special Hazards
• B. Health hazard
• C. Reactivity
• D. Flammability

Answer: (A)

Special hazards are indicated in the white quadrant of the NFPA 704 hazard diamond. This white area sits apart from the blue, red, and yellow fields and is used to flag hazards that don’t fit into health, flammability, or reactivity ratings. The white section may show letters or symbols to warn about specific conditions, such as water reactivity (W with a slash) or oxidizers, or other special considerations that require particular handling or PPE. In short, the white quadrant communicates Special Hazards.
