What does AFFF stand for?

AFFF stands for Aqueous Film Forming Foam. This type of foam is specifically designed to combat flammable liquid fires, primarily those involving hydrocarbons such as gasoline or oil. The unique properties of AFFF allow it to form a thin film on the surface of burning liquids, which helps to suppress the release of flammable vapors and effectively smother the fire.

The primary mechanism of AFFF is its ability to create a barrier that not only cools the fire but also prevents oxygen from reaching the fuel, thus interrupting the combustion process. This makes it an essential tool for firefighters dealing with hazardous material incidents and industrial firefighting scenarios. Its effectiveness in quickly controlling fires and limiting fire spread is crucial in minimizing damage and enhancing safety during firefighting operations.

Understanding the specific function and application of AFFF is vital for any advanced technician firefighter, as it plays a significant role in modern firefighting strategies.
