In the NFPA hazard diamond, which color represents Health hazards?

Explanation:
Blue is the color that communicates health hazards in the NFPA 704 hazard diamond. This system uses four colored sections to label different hazard types: blue for health, red for flammability, yellow for reactivity, and white for special hazards. Each section carries a 0–4 rating indicating how severe the hazard is, with higher numbers signaling greater risk to health, ignition potential, or reactivity. The blue section specifically tells you how dangerous exposure or contact could be to a person, guiding protective measures and first aid responses.
