In the NFPA diamond, blue quadrant indicates health.

Explanation:
The blue quadrant in the NFPA 704 diamond flags health hazards—the potential for injury or illness from exposure to the substance. The numbers in this blue area run from 0 to 4, with 0 meaning no health hazard and 4 indicating a severe hazard that could cause death or serious injury from brief exposure. This color-coding system is designed to give responders a quick read on how dangerous a material is to health, guiding the level of PPE and exposure controls needed. The other quadrants cover different hazards: red for flammability, yellow for reactivity/instability, and the white section for special hazards such as oxidizers or water reactivity.
