PHOS-CHEK 3×3% AR-AFFF Freeze Protected Foam supplied by PHOS-CHEK

PHOS-CHEK 3×3 AR-AFFF FP (Alcohol-Resistant Aqueous Film Forming Foam Freeze Protected) is a mixture of water, hydrocarbon surfactants, solvents, C6 fluorosurfactants and fluoropolymers. The product is a 3% concentrate proportioned solution for use on both Hydrocarbon and polar solvent fires. This new formulation demonstrates ICL Performance Products commitment to superior firefighting performance and environmental responsibility.

PHOS-CHEK 3×3 AR-AFFF FP is designed for rapid control and knockdown by producing a thin aqueous film on hydrocarbon fuels or a polymer membrane on polar solvent fuels that minimize vapor release, a foam blanket that separates the fuel from the air, and continual draining of water from the foam blanket provides cooling at the fuel surface.

The product can be used at temperatures as low as 0 degrees F.


Phos-Chek 3×3 AR-AFFF FP is used in fire suppression systems and manual applications to fight a broad range of Class B flammable liquid fires including hydrocarbon fuels such as gasoline and diesel, and on polar solvent fuels such ketones and alcohols. Typical applications include storage tanks, loading racks, docks, process areas, warehouses, and is an excellent vapor suppressor for flammable liquid spills.


UL 162, EN 1568-3 (Class IA) and EN 1568-4 (Class IB)


The concentrate should be stored at temperatures between 0 ̊F (-17 ̊C) and 122 ̊F (+50 ̊C), preferably in the original containers, approved bladder tanks, stainless steel, high density polyethylene, fiberglass or epoxy lined tanks. Concentrate piping acceptable materials of construction include stainless steel (either 304 or 316), some plastic piping including fiberglass and PVC, red brass, and black iron as long as the system is completely flooded eliminating the air/foam concentrate/carbon steel interface. Avoid permanent contact with carbon steel, iron, some copper alloys, & aluminum when the piping material and concentrate will be exposed to air. Galvanized piping is not recommended for AFFF piping systems.Foam concentrates are subject to evaporation, which accelerates when the product is exposed to air. Storage tanks should be sealed and fitted with a pressure vacuum vent to prevent free exchange of air.


The shelf life of any foam concentrate is maximized by proper storage conditions and maintenance. Factors affecting shelf life are wide temperature changes, extreme high or low temperatures, evaporation, dilution, and contamination by foreign materials. Properly stored Phos-Chek AR-AFFF Class B foam concentrates should have no significant loss of firefighting performance for 20+ years. However, the National Fire Protection Association (NFPA) recommends annual testing of all firefighting foams.
