What is NFPA 704?
The National Fire Prevention Association (NFPA) standard “NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response” is a safety standard that defines how hazardous materials are identified for emergency responders.
This standard provides information on a rating system for potentially hazardous materials. This is vital information to emergency personnel, who use it to educate their decisions on firefighting techniques and the use of personal protective equipment.
The NFPA 704 sign, also known as a “fire diamond” or NFPA diamond, uses the color and number codes described in NFPA 704 to provide all of this life-saving information to responders at a glance.
Each color designated by NFPA 704 represents a different type of hazard: health, flammability, and reactivity.
The severity of each type of hazard is graded by the system of numbers, with 0 standing for the lowest severity and a rating of 4 being the highest.
The white section is only used for special hazards. A majority of NFPA 704 signs will have a blank white section.
