What does AFFF stand for in fire extinguishing agents?

The correct answer is Aqueous Film Forming Foam. This term refers to a specific type of fire suppression agent that is particularly effective for extinguishing flammable liquid fires. AFFF works by forming a film on the surface of the burning liquid, which helps to smother the fire and prevent re-ignition.

This type of foam is advantageous in that it can not only suppress flames but also cool the fuel underneath the foam blanket. The aqueous component allows the foam to spread quickly and form a barrier, enhancing its effectiveness against a variety of flammable materials. Understanding the properties and functions of AFFF is crucial for firefighters, as it informs their approach to fighting fires involving flammable liquids safely and effectively.
