    • Lab Safety Hazard Label
    • The National Fire Protection Association (NFPA) has developed a system to indicate the health, flammability, and reactivity hazards of chemicals. In addition, a special precaution symbol may be used.
    • Hazard Labels • The NFPA’s hazard labels are shaped like diamonds. The top section reveals the flammability of a substance. The left section indicates a substance’s health hazards. The right section tells how reactive a substance is with other substances.
