PHOS-CHEK 3×6% AR-AFFF (Alcohol-Resistant Aqueous Film Forming Foam) is a mixture of water, hydrocarbon surfactants, solvents, C6 fluorosurfactants and fluoropolymers. The product is a 3% concentrate proportioned solution for use on hydrocarbon fires, and 6% on polar solvent fires. This novel formulation demonstrates Perimeter Solutions’ commitment to superior firefighting performance and environmental responsibility.

PHOS-CHEK 3×6 AR-AFFF is designed for rapid control and knockdown. The product produces 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, which provides cooling at the fuel surface.

APPLICATIONS

Phos-Chek 3×6 AR-AFFF 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.

APPROVAL CERTIFICATIONS

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

STORAGE AND HANDLING

The concentrate should be stored at temperatures between 23 ̊F (-5 ̊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.

SHELF LIFE, INSPECTION AND TESTING

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.
