NFPA 704 diamond primarily conveys which information?

Explanation:
NFPA 704 conveys hazard information using four fields on the diamond: blue for health, red for flammability, yellow for reactivity (instability), and a white area for special hazards. The first three fields carry numeric ratings from 0 to 4, with higher numbers indicating greater hazard, while the white area lists specific hazards (like oxidizers or radioactive materials) with symbols such as OX or W. So the information provided is Health, Flammability, Reactivity, and Special Hazard Ratings. PPE and ventilation needs aren’t encoded in the diamond itself, though they’re considered when using the material based on these ratings.
