What does the number on an NFPA label represent?

The number on an NFPA (National Fire Protection Association) label represents the severity of hazards associated with a particular material, using a scale from 0 to 4. This scale is a standardized method for assessing the degree of risk posed by fire, health, and reactivity hazards.

• A rating of 0 indicates minimal risk, while a rating of 4 signifies a severe hazard that poses a significant risk to health, safety, and the environment.

• This numerical classification helps first responders and safety personnel quickly assess the dangers involved and respond appropriately to incidents involving hazardous materials.

Understanding this scale is crucial for effective hazard communication and response, as it informs the level of protective measures needed when handling or in the vicinity of the hazardous material.
