Aqueous Film-Forming Foam (AFFF) concentrates combine fluoro- and hydrocarbon-surfactant technologies to produce high performance synthetic firefighting foams suited for use on class B hydrocarbon fuel fires such as oil, petroleum, gasoline, benzene, and aviation fuels.
AFFF solutions utilize three suppression mechanisms for rapid fire knockdown and burnback resistance:
Fast fire knockdown make AFFF concentrates particularly useful in applications that involve quick rescue from hydrocarbon fires. For example, offshore platforms utilize AFFF for process areas and helideck protection, whilst the aviation sector uses AFFF concentrates in ARFF (Aircraft Rescue Fire Fighting) vehicles for crash rescue scenarios. Although very effective on Class B hydrocarbon fires, AFFF concentrates should not be used on polar solvent fires.
