Firefighting foam - Wikipedia
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) - Consumer Notice
Aug 31, 2023 · Aqueous film forming foam (AFFF) is a fire suppressant used to fight flammable liquid fires. Toxic chemicals in AFFF may cause serious health problems.
AFFF foam – All you need to know - E.P.Fire: Independent …
Dec 20, 2022 · What is AFFF foam? AFFF (Aqueous Film Forming Foam) is a fluorine-containing firefighting foam primarily used to extinguish flammable liquids such as petrol. It forms a water film between the flammable liquid and the foam, and this allows the foam to spread easily and knock down the flames quickly.
Understanding AFFF Exposure and VA Claims - benefits
May 17, 2024 · Aqueous Film Forming Foam (AFFF) is a firefighting foam that has been used extensively by the military and civilian firefighters for decades. However, there is growing evidence that exposure to AFFF can cause serious health effects.
NFPA Journal – The New Foam, Fall 2022
Jul 22, 2022 · With AFFF being phased out and new firefighting foams being developed, the fire protection world braces for what’s next.
A Comprehensive Guide to Understanding AFFF and AR-AFFF
Oct 4, 2024 · When it comes to firefighting foam, we can divide it into two basic types: aqueous film-forming foam (AFFF) and alcohol-resistant aqueous film-forming foam (AR-AFFF). Both types create a film that blankets the fuel surface, smothering the fire and preventing re-ignition.
Aqueous Film Forming Foam (AFFF) Status and Alternatives: The …
Mar 8, 2024 · Aqueous film forming foam (AFFF) has been the industry standard for combatting liquid fuel fires and hazards for almost 50 years. AFFF is a water-based solution that contains a fluorinated, film forming surfactant [per- and poly-fluoroalkyl substances (PFAS)] to seal the fuel surface during suppression/extinguishment. All “AFFFs” contain PFAS.
Aqueous Film Forming Foams (AFFF) - Hiller Fire
AFFF is a combination of fluorocarbons, surfactants, and solubilizers. The fluorochemical based surfactant reduces the surface tension of water allowing the foam to form an aqueous film on the surface of the hydrocarbon fuel that: (1) suppresses vapors. (2) deprives the fuel surface of oxygen, and. (3) prevents evaporation and subsequent re ...
Aqueous film-forming foam (AFFF) is a highly effective firefighting product intended for fighting high-hazard flammable liquid fires. AFFF products are synthesized by combining hydrocarbon foaming agents with fluorinated surfactants to achieve a product that has been used at military installations, civilian airports, petroleum refineries, bulk ...
Exploring Innovative Alternatives to AFFF Foam for Safer Fire …
1 day ago · Fluorine-Free Foam (F3) Fluorine-free foams (F3) show great promise as a substitute for AFFF. Unlike AFFF, which contains toxic fluorinated compounds, F3 is biodegradable and has no long-term environmental hazards. It is equally effective in extinguishing fires, especially those with flammable liquids. Hence, it’s an excellent choice for the ...
