Which NFPA 704 color indicates flammability?

Which NFPA 704 color indicates flammability?

• A. Health (blue)
• B. Flammability (red)
• C. Reactivity (yellow)
• D. Special information (white)

Answer: (B)

NFPA 704 uses a diamond divided into four colored sections to quickly convey different hazard kinds. Each color has its own meaning: blue for health, red for flammability, yellow for reactivity, and white for special information. The red section specifically communicates how easily a material can ignite and burn, with the numbers inside indicating the degree of hazard from 0 to 4. Since the question asks which color indicates flammability, the red section is the one that represents flammability.
