What is the NFPA label used for?

The NFPA label serves as an essential tool for quickly conveying the hazards associated with materials. It employs a color-coded number system to indicate the severity of risks related to fire, health, and reactivity. The label features a diamond shape, where each quadrant is designated by a specific color—blue for health hazards, red for flammability, yellow for reactivity, and white for specific hazards. The numbers within these colored sections range from 0 (no hazard) to 4 (severe hazard), allowing first responders and personnel handling the materials to assess potential dangers at a glance. This system promotes safety by enabling informed decision-making and prompt action when dealing with hazardous substances.

Other options do not accurately reflect the primary purpose of the NFPA label; it does not apply to non-hazardous materials, assess shelf life, or evaluate environmental impacts directly.
