What is the NFPA 704 system used for?

The NFPA 704 system is specifically designed to communicate the hazards associated with materials through a clear, color-coded label system. This system utilizes a diamond-shaped label featuring a numerical scale ranging from 0 to 4 in four quadrants, which indicate the level of health, flammability, reactivity, and specific hazards of the material. The intent is to provide first responders, firefighters, and hazardous materials personnel with immediate understanding of the risks posed by substances in emergency situations.

This clarity in hazard communication is crucial for ensuring safety and facilitating appropriate response measures during incidents involving hazardous materials. By using this standardized labeling system, responders can quickly assess the nature of the threat and make informed decisions about how to approach containment, evacuation, and other emergency procedures.
