In the early 1970s, National Foam, Inc. invented alcohol-resistant AFFF technology. AR-AFFF is a synthetic foam developed for both hydrocarbon and polar-solvent materials. Polar solvents are combustible liquids that destroy conventional fire-fighting foam.
1967 In the wake of the 1967 USS Forrestal fire, which happened off the coast of north Vietnam—"one of the worst disasters in U.S. naval history"—in which 134 people were killed and the U.S. Navy aircraft carrier was almost destroyed, the US Navy began to make it mandatory for its vessels to carry Aqueous Film Forming Foams (AFFF) on board ...
AFFF was developed in the 1960s under Project Light Water in a joint venture between 3M and the U.S. Navy. AFFF forms a film that floats out before the foam blanket, sealing the surface and smothering the fire by excluding oxygen. AFFF is widely used for ARFF firefighting at airports, often in conjunction with purple-K dry chemical.

The unit is then filled with 1.5 US gallons (5.7 L) of water and class A foam, AFFF, FFFP or commercial detergent is added to the water in a 1% ratio for class A fires and a 3%-6% ratio for class B fires. Typically, the tip of the smooth-bore application nozzle is then cut off to allow the foam to properly expand.
