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.

2023年8月31日 · Aqueous film forming foam (AFFF) is a fire suppressant used to fight flammable liquid fires. Toxic chemicals in AFFF may cause serious health problems.

2025年1月2日 · 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.

2024年6月8日 · Aqueous Film Forming Foam (AFFF) stands as a frontline defence against flammable liquid fires, renowned for its rapid extinguishing capabilities. In this article, we explore the complete facts surrounding AFFF, shedding light on its composition, applications, benefits, and drawbacks.

2022年12月20日 · 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 …

1 天前 · Aqueous film-forming foam (AFFF) is used to extinguish high-intensity fuel fires — but the key ingredient that makes this foam so effective may also put first responders at serious risk. Exposure to PFAS (perfluoroalkyl and polyfluoroalkyl substances) in firefighting foam has been linked to over a dozen types of cancer and other health ...

2024年4月26日 · Aqueous film forming foam (AFFF) is a synthetic, water-based surfactant designed as a Class B foam (designed for primarily gasoline fires). The foam smothers the fire and deprives it of...

( e.g., non-stick cookware, waterproof fabric, and firefighting foam). In the 1970s, DoD began using AFFF that contained PFOS and, in some formulations, PFOA. This mission critical product saves lives and protects assets by quickly extinguishing petroleum-based fires, and the Federal Aviation Administration required its use at airports nationally.

1 天前 · Aqueous Film-Forming Foam (AFFF) is a fire-suppressing foam used primarily by firefighters and the military to combat high-intensity fires. While effective at extinguishing fires, it contains harmful chemicals known as PFAS (per- and polyfluoroalkyl substances), including PFOA (perfluorooctanoic acid). These chemicals are persistent in the ...

AFFF foam concentrate are designed for rapid fire knockdown by producing a thin aqueous film which helps to prevent the release of fuel vapours. The foam blanket, from which the film forming liquid drains separates oxygen from the fuel surface, extinguishes the fire and prevents re-ignition.
