Multiple Choice

In the NFPA diamond, white quadrant indicates special hazards.

Explanation:
The white quadrant in the NFPA 704 diamond is reserved for special hazards that aren’t captured by the numeric ratings. It flags unique or nonstandard hazards, such as oxidizers (OX) or water-reactive materials (W, sometimes with a slash). The other colored quadrants—blue for health, red for flammability, and yellow for reactivity—each carry a 0–4 scale for those specific properties. Since the white area is specifically meant for these special hazard codes, it indicates special hazards. You’ll sometimes see additional symbols or letters in this space to convey that extra caution.
