What does the RED diamond of the NFPA 704 marking system indicate?

Explanation:
The red diamond shows how flammable the material is. It communicates the material’s tendency to ignite and burn, with numbers from 0 to 4 where 0 means not flammable and 4 means extremely flammable. This helps you assess fire risk quickly during handling, labeling, or emergency response. The other diamonds cover different hazards: blue for health hazard, yellow for reactivity, and the white diamond for specific hazards like oxidizers or unusual reactivity. So the red diamond is specifically about flammability.
