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. Selecting the best product for your application is key. These products are typcially used in chemical and petrochemical plants, refineries, oil and gas storage facilities, flammable liquid storage facilities, airports and anywhere flammable liquids are stored or used. In addition to AFFF and AR-AFFF, ICL offers Fluorine Free foams formulated to fight both hydrocarbon and polar solvent fires, Training Foam and other Specialty foams.
