If placard shows 0, what does it indicate?

If placard shows 0, what does it indicate?

• A. No risk
• B. Low risk
• C. High risk
• D. No information

Answer: (A)

On NFPA 704 hazard placards, numbers 0 through 4 rate hazard levels in three areas: health, flammability, and reactivity. A rating of 0 means no hazard in that category. If a placard shows 0 across all dimensions, it indicates no health risk, no flammability risk, and no reactivity risk for that material. In other words, there is no hazard indicated by the placard. If any category had a higher number, there would be some level of risk in that area, even if the others are 0.
