USAFE GREEN AR-AFFF foams (Alcohol-Resistant Aqueous Film-Forming Foam) provide efficient vapor suppression and extinguishment of liquid class B fires containing hydrocarbons and polar solvents. AR-AFFF foams are required when fuels are water-miscible, such as alcohols, acetone… Polar solvents and alcohol are able to destroy the foam blanket generated by standard class B hydrocarbon fires foams. AR-AFFF foams are often required in high-risks facilities in the oil & gas and chemical industries such as refineries, ships, tank farms and pharmaceutical plants.
AR-AFFF foams are suitable for quick extinguishment of large-scale class B fires. AR-AFFF agents contain a polymer that forms a protective film between the burning surface and the foam blanket, blocking the oxygen which supplies the fuel in fire. By forming a polymer layer, it seals the fuel surface and prevents the release of fuel vapors. AR-AFFF film prevents foam breakdown by alcohols in the burning liquids. The water contained in the foam solution provides a cooling effect for faster fire suppression. USAFE GREEN AR-AFFF foams had a good burn back resistance.
USAFE GREEN high performance synthetic AR-AFFF foams can be applied in direct or indirect application with a wide range of firefighting equipment. They can be used in high, medium and low expansion on the burning spill. USAFE GREEN AR-AFFF foams are tested and approved by international standards appropriate to your industry, application and risk (EN1568, UL, NFPA, LASTFIRE, IMO…).
Considering the growing concerns about fluoro-surfactants, USAFE GREEN uses C6 surfactants (short-chain) recognized as safer, and minimizing the impact on health and environment, than PFOS and PFOA. The use of PFOS and PFOA is restricted all over the world due to their persistence in the environment, bio-accumulative characteristics and containing toxic substances.
