The National Fire Protection Association (NFPA) 704 Diamond is a concise system for identifying the hazards associated with specific materials.
The NFPA 704 Diamond placard is found on fixed facilities where hazardous materials are used or stored.
The diamond is divided into four colored quadrants, each with a rating number inside of it, which indicates the degree of risk associated with the material.
Numbers range from 1 to 4. The higher the number the higher the risk!
