NFPA Standards

The NFPA 704 standard provides a readily recognized, easily understood system for identifying specific hazards and their severity using spatial, visual, and numerical methods to describe in simple terms the relative hazards of a material. It addresses the health, flammability, instability, and related hazards that may be presented as short-term, acute exposures that are most likely to occur as a result of fire, spill, or similar emergency.

The 704 rating system is applicable to industrial, commercial, and institutional facilities that manufacture, process, use, or store hazardous materials.
