What does AFFF stand for in firefighting?

Aqueous Film Forming Foam (AFFF) is a type of firefighting foam specifically designed to combat flammable liquid fires. Its unique composition allows for it to spread quickly over the surface of flammable liquids, forming a film that helps to smother the fire and prevent vapors from igniting. This is particularly important in firefighting scenarios involving chemicals and fuels, where creating a barrier between the fuel and the air can be crucial for extinguishing the flames effectively.

Understanding the function of AFFF is vital for firefighters, as it provides a significant advantage in suppressing fires involving flammable liquids. The foam not only cools the fire but also cuts off the oxygen supply needed for combustion. This characteristic is essential in any effective firefighting strategy dealing with hazardous materials.
