Pre-action foam systems
Fire suppression foam is comprised of three parts: foam concentrate, water, and air. When mixed correctly, these parts form a homogeneous foam blanket that extinguishes flames by the combined mechanisms of cooling, separating the flame source from the product surface, suppressing vapors, and smothering. This makes foam suppression systems an effective option for protecting flammable and combustible liquids. AFFF -Aqueous Film Forming Foam is water-based foams extinguish fires by forming an air-tight film that cuts the fire off from its oxygen supply. Simply put: no oxygen, no fire. Its characteristics make it the preferred fire protection system for any area where flammable liquids are stored in Fuel Tanks, Chemical processing plants and aircraft hangars.
