In the context of fire fighting, what does AFFF stand for?

AFFF stands for Aqueous Film Forming Foam. This type of foam is specifically designed for fire suppression, particularly on flammable liquid fires such as those involving fuels, oils, and solvents. AFFF is highly effective because it forms a film on the surface of the burning liquid, which helps to suppress the vapor and prevent re-ignition by cooling the fire and creating a barrier that separates the fuel from the oxygen needed for combustion.

The formulation allows it to spread quickly over surfaces which aids in rapid fire knockdown. This makes it a preferred option for fighting fires on ships and in environments where flammable liquids are present. Understanding the properties and applications of AFFF is critical for effective fire fighting and damage control operations.
