In NFPA 704 hazard diamonds, which color represents flammability?

• A. Red
• B. Blue
• C. Yellow
• D. White

Answer: (A)

Red represents flammability in the NFPA 704 hazard diamond. The diamond uses four colored panels to indicate different hazards: blue for health, red for flammability, yellow for reactivity, and white for special hazards. Each panel carries a 0–4 rating, with higher numbers showing greater risk. So, the red panel specifically communicates how easily the material can ignite, while blue, yellow, and white convey health, reactivity, and special hazards, respectively.
