In the mid-1960s, the US Navy developed aqueous film-forming foam (AFFF). This synthetic foam has a low viscosity and spreads rapidly across the surface of most hydrocarbon fuels. A water film forms beneath the foam, which cools the liquid fuel, stopping the formation of flammable vapors.
Aqueous film-forming foam (AFFF) (pronounced "A-Triple-F", also called "Class B"): bubbles that act as surfactant to coat and penetrate ordinary fuels (e.g., wood, paper) to prevent them from burning at normal temperatures; also used on "Class B" (oil/gasoline) fires to spread a non-volatile film over the surface of the fuel.
Aqueous film-forming foam (AFFF), used on A and B fires and for vapor suppression. The most common type is portable foam extinguishers. The most common type is portable foam extinguishers. 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 ...
For years, departments used aqueous film-forming foam (AFFF) that contained high concentrations of PFAS. The state's new ban on "legacy foams" is possible because new, PFAS-free foams are available.
Aqueous film forming foam, or aqueous fire fighting foam Australian Farmers' Fighting Fund , a body providing financial, legal, and professional assistance to farmers in Australia Topics referred to by the same term
The material, known formally as aqueous film-forming foam, or AFFF, was developed in the 1960s to fight extremely hot, dangerous fires started by flammable liquids. The foams containing forever ...
The most common extinguisher is the ABC extinguisher and are found in most offices and homes. It can be used on normal fires, liquid fires, and electrical fires. There are also special extinguishers for kitchen fires and for use on burning metals, those being Class K and Class D respectively.
In 1971 Chubb Fire Security Ltd was formed. In that same year a Bristol Britannia aircraft, flown by test pilot Donald Chubb, landed on a carpet of Pyrene foam at Manston. In 1976 Fireward Ltd, manufacturers since 1964 of plastic-bodied portable dry-powder fire extinguishers, also merged with Pyrene Panorama, to form the new company, Chubb ...
