NFPA 13 Hazard Classifications

NFPA 13 Hazard Classifications generally fall into one of three categories: Light, Ordinary, and Extra. Light Hazard occupancies are considered to be less combustible than Ordinary or Extra Hazard occupancies and, thus, have a lower expected heat release from fires. Extra Hazard occupancies, on the other hand, are considered highly combustible and pose additional risks that may accelerate a fire.

Buildings classified as Light Hazards include churches, healthcare facilities, offices, and schools. Ordinary Hazards are sorted into two groups. with Group 1 including food processing facilities, mechanical plants, and other manufacturing operations that release moderate rates of heat. Group 2 contains auto repair shops, barns, distilleries, libraries, and machine rooms.

Extra Hazards are also divided into two groups. Group 1 deals with occupancies that contain combustible or flammable liquids but is generally used to classify buildings with highly combustible solids. Group 2, on the other hand, deals with occupancies like automobile paint spray booths, plastic manufacturing operations, and steel manufacturing operations.

What Are The Risks Of Not Adhering To NFPA 13?

NFPA 13 serves as a minimum standard for the installation of Automatic Fire Sprinkler Systems and components. Failing to adhere to these guidelines may be putting your building and the people inside it at risk. Many states and municipalities use NFPA guidelines when constructing their own local codes. NFPA 13 is a widely recognized standard used by fire sprinkler codes and fire protection companies. Some areas, like California, for example, may even expand upon NFPA 13 to fit the state’s fire protection needs.
