What does the red section of the NFPA diamond indicate?

• A. Flammability
• B. Health Hazard
• C. Reactivity
• D. Special Hazard

Answer: (A)

In the NFPA 704 diamond, the color coding quickly communicates different hazard types, and the red section specifically shows flammability—the material’s tendency to ignite and burn. The numbers in that red area (0 to 4) rate how easily it can catch fire or sustain combustion, with 0 meaning it won’t burn under normal conditions and 4 indicating it is extremely flammable. This guides precautions like keeping ignition sources away, using proper storage and ventilation, and applying appropriate fire protection measures. The blue section covers health hazards, the yellow section covers reactivity, and the white section notes any special hazards.
