What does a higher NFPA number indicate?

• A. Higher hazard
• B. Lower hazard
• C. Less hazard for health
• D. Only affects labeling color

Answer: (A)

A higher NFPA number indicates greater hazard in that specific category. NFPA 704 uses three numbers (0–4) in blue for health, red for flammability, and yellow for reactivity to show how dangerous a material is in each area. The higher the number, the more serious the hazard. For example, a substance with a high flammability number can ignite readily, while a low number means little to no fire hazard. The colors help identify the type of hazard at a glance, but the numbers quantify how severe that hazard is. So a larger number signals more danger in that aspect, not just a different color or a lower hazard overall.
