Flammable liquid fires require specialized foams that are designed to both extinguish a fire and prevent reignition or burnback. Aqueous Film Forming Foams (AFFF) and Alcohol resistant AFFF (AR-AFFF) form a film between the fuel and the air, dealing the surface and preventing the escape and ignition of flammable vapors. AR-AFFF is specially designed to prevent polar solvents from destroying the foam blanket. AFFF and AR-AFFF come in a variety of formulations with varying mix rates (1%, 3% or 6%), viscosities and freezing points. ICL offers AFFF additives and AFFF solutions for portable fire extinguishers. These additives make liquid extinguishers far more effective than plain water. Liquid extinguishers have also been shown to cause far less peripheral damage than powder extinguishers. To explore the Auxquimia brand Fire Extinguisher Additives, please click here.
