Red on facility placards represents which hazard?

• A. Blue on facility placards represents health hazards.
• B. Red on facility placards represents reactivity hazards.
• C. Red on facility placards represents flammability hazards.
• D. Blue on facility placards represents flammability hazards.

Answer: (C)

Notice how the NFPA 704 hazard diamond uses colors to quickly signal different risks: blue flags health hazards, red flags flammability, yellow flags reactivity, and white notes special hazards. The red section is specifically about flammability—how easily a material can ignite or burn. The numbers in that red area (0–4) indicate the level of flammability risk, with higher numbers meaning greater danger. So red on facility placards represents flammability hazards.
