When deciding which fire suppression system is most appropriate for your application, you first need to determine the correct hazard classification. There are several, and the 5 most common are class A, class B, class C, class D, and class K. We will be discussing class B hazards and which type of fire protection is most effective.

Class B hazards include Flammable liquids, greases, and gas. The best solution to these fire hazards are dry chemical powder or clean agent gas. Why not water? Because a solid stream of water can cause the fuel to scatter; this will spread the flames.

Beyond knowing your fire hazard classification, you also need to understand your area hazard classification. Because any of these area hazard classifications can be a class B fire hazard, we will discuss all three options.

Extra (High) Hazard

Extra (High) hazard occupancies shall be classified as locations where the quantity and combustibility of Class A combustible material is high or where high amounts of Class B flammables are present and rapidly developing fires with high rates of heat release are expected
