Which NFPA hazard categories are described in the material?

Which NFPA hazard categories are described in the material?

• A. Health, Fire, and Reactivity
• B. Health and Environmental
• C. Fire and Water reactivity
• D. Oxygen hazard only

Answer: (A)

NFPA 704 label uses three hazard categories to describe a chemical’s risk: health, fire (flammability), and reactivity. The blue section signals health hazards (risk to people), the red section signals fire hazards (how easily it ignites), and the yellow section signals reactivity hazards (stability and tendency to react). Environmental hazards aren’t part of these main categories in NFPA 704; they are addressed by other labeling systems. The three categories described are therefore health, fire, and reactivity.
