What does the symbol “NFPA 704” indicate?

The symbol “NFPA 704” refers to a labeling system for hazardous materials, specifically used to identify the hazards of materials in a standardized way to ensure safety for emergency responders and the public. This system employs a color-coded diamond with numerical ratings to indicate the level of health, flammability, reactivity, and special hazards associated with a substance. The documentation and regulation of hazardous materials is vital for fire inspectors as it assists in understanding the risks involved in potential fire incidents, enabling them to make informed decisions about enforcement and response strategies. Understanding this labeling system is crucial for fire inspectors because it directly impacts both their safety and the safety of the community.
