Aqueous Film Forming Foam (AFFF) is an indispensable element in fire safety, primarily utilized to combat fires involving flammable liquids such as gasoline, oil, and solvents. This firefighting agent forms a thin film on the surface of the burning liquid, effectively smothering the flames and preventing re-ignition.

When applied to a fire, AFFF creates a protective barrier that rapidly suppresses the flames by sealing off the oxygen supply. It is particularly effective for extinguishing Class B fires, which involve flammable liquids, and is also suitable for some Class A fires, which involve ordinary combustible materials like wood and paper.

AFFF is commonly deployed using foam proportioning systems and foam generating equipment in various settings, including industrial facilities, airports, refineries, and petrochemical plants, where the risk of fires involving flammable liquids is high.

In essence, Aqueous Film Forming Foam (AFFF) plays a critical role in fire safety, providing a reliable and versatile solution for extinguishing fires involving flammable liquids and preventing their spread, thereby contributing to overall fire prevention and protection measures.
