- Features and Specs
The first certified fluorine free Class A/B firefighting foam, PHOS-CHEK® 1% fluorine free foam concentrate is a mixture of water and hydrocarbon surfactants. Developed for use on Class B hydrocarbon fuel fires, this organohalogen free foam is an environmentally responsible next generation product, that demonstrates Perimeter Solutions’ commitment to superior firefighting performance and environmental responsibility. PHOS-CHEK 1% fluorine free foam is designed for rapid control and knockdown in both gentle and forceful applications on hydrocarbon fuel fires. Use of fluorine free foam is an option for spill fires and are typically used in lower hazard fire scenarios. PHOS-CHEK 1% fluorine free foam is an extremely effective wetting agent for use on Class A fires involving ordinary combustible materials such as wood, cloth, paper, rubber and many plastics.
PHOS-CHEK 1% fluorine free foam concentrate is designed for use on Class B hydrocarbon fuel fires (gasoline, crude oil, aviation fuels, diesel, etc.) at 1% proportioning. The foam concentrate is not intended for use on Class B polar solvents or water miscible fuels such as alcohols, ketones, esters and others. On Class A fuels, the foam concentrate is used as a wetting agent in accordance with ANSI/NFPA 18. PHOS-CHEK 1% fluorine free foam concentrate is compatible with conventional firefighting equipment such as low expansion non-air aspirating and air aspirating nozzles and monitors, medium expansion foam devices and Compressed Air Foam Systems (CAFS).
UL 162/ULC S654 Listed, UL/ULC Classified Class A Wetting Agent ANSI/NFPA 18, EN-1568-3:2008 (Class 1B) Approved.
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 fluctuation, evaporation, dilution, and contamination by foreign materials. Properly stored PHOS-CHEK 1% fluorine free foam concentrates should have no signifi cant loss of fire fighting performance for 20+ years. However, the National Fire Protection Association (NFPA) recommends annual testing of all fire fighting foams.
WETTING AGENT APPLICATION RATES
UL/ULC Classified 0.1% for Class A fires and 0.25% for Class B Non-Water Miscible Fires • Class A fire use, mix 0.1 part foam concentrate to 99.9 parts water. • Class B fire use, mix 0.25 part foam concentrate to 99.75 parts water.
Unlike legacy C8 and mixed homologue based fluorinated firefighting foams (AFFF, AR-AFFF, FFFP, AR-FFFP, FP, AR-FP) which are considered to be toxic and bioaccumulative based on current regulatory criteria, PHOS-CHEK 1% fluorine free foam concentrate does not contain any PFAS ingredients commonly found in fluorinated Class B foam concentrates.
STORAGE AND HANDLING
The concentrate should be stored at temperatures between 35˚F (1.7˚C) and 120˚F (49˚C), preferably in the original containers, approved bladder tanks, stainless steel, high density polyethylene, fiberglass or epoxy lined tanks. Concentrate piping acceptable
