PHOS-CHEK 3% Aqueous Film Forming Foam-Freeze Protected (AFFF-FP) concentrate is a mixture of water, hydrocarbon surfactants, solvents, and C6 fluorosurfactants. This C6 based AFFF is an environmentally responsible, next generation Aqueous Film Forming Foam (AFFF) product for use on Class B hydrocarbon fuels that have low water solubility. This new formulation demonstrates ICL Performance Products commitment to superior firefighting performance and environmental responsibility.

The pure C6 PHOS-CHEK 3% AFFF-FP is designed for rapid control and knockdown by producing a thin aqueous film that minimizes vapor release, a foam blanket that separates the fuel from the air, and continual draining of water from the foam blanket provides cooling to the fuel surface.

PHOS-CHEK 3% AFFF FP can be used at temperatures as low as 0 degrees F.


Phos-Chek 3% AFFF-FP may be used with low expansion foam equipment (nozzles, monitors, foam chambers, etc.), non-aspirating devices (water spray nozzles and standard sprinklers) and medium expansion foam devices to fight fires involving Class B hydrocarbon fuel fires such as crude oil, aviation fuels, diesel, etc. It is not suitable for use on polar solvents or water miscible fuels such as alcohols, ketones, esters, and ethers.


UL 162 and EN 1568-3 (Class IB) listed, Foam Liquid Concentrates


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 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.
