What does NFPA 704 specifically address?

NFPA 704 specifically addresses hazard identification for emergency response through a standardized labeling system that is widely recognized. This system uses a color-coded diamond shape, divided into four quadrants, to indicate the level of health hazard, flammability, reactivity, and specific hazards associated with materials. The primary goal of NFPA 704 is to provide immediate, easily interpretable information to emergency responders about the hazards present at a location, enabling them to make informed decisions when managing incidents involving chemicals and hazardous materials. This labeling system is crucial for ensuring safety during firefighting and rescue operations, as it quickly communicates potential dangers to responders who may not be familiar with the specific substances involved in an emergency. The other options do not pertain to the NFPA 704 standard, which is focused exclusively on hazard communication rather than training, electrical standards, or building codes.
