The National Fire Association (NFPA) has developed a color-coded number system called NFPA 704. The system uses a color-coded diamond with four quadrants in which numbers are used in the upper three quadrants to signal the degree of health hazard (blue), flammability hazard (red), and reactivity hazard (yellow).
What is an NFPA label?
The NFPA diamond label is used to warn firefighters and other emergency responders of the hazards they would be exposed to in a fire or chemical spill situation. Colors indicate the type of hazard. Numbers indicate the degree of hazard. 0 = Materials that offer no hazard beyond that of ordinary combustible materials.
