In NFPA 704 hazard diamond, which color indicates health hazard?

Explanation:
The blue quadrant is used to show health hazard in the NFPA 704 hazard diamond. The numbers inside the blue area range from 0 to 4, indicating how severe the health risk is—0 means no hazard, while 4 indicates a severe or life-threatening hazard. This color coding helps responders quickly assess the potential health risks and decide on appropriate protective measures. The other colors serve different purposes: red for flammability, yellow for reactivity, and white for special hazards such as oxidizers or water reactivity.
