Which NFPA 704 color indicates health hazards?

Explanation:
In NFPA 704 labeling, the blue section of the diamond indicates health hazards. The number inside that blue area shows how severe the health risk is if someone is exposed, ranging from 0 (no hazard) to 4 (severe or life-threatening). The other colors cover different dangers: red for flammability, yellow for reactivity, and white for special hazards (like oxidizers or corrosives). So blue is the color that specifically communicates health hazards, making it the correct choice.
