What does AFFF stand for in firefighting?

AFFF stands for Aqueous Film Forming Foam, which is a type of firefighting foam used to combat flammable liquid fires, such as those involving petroleum products. The name highlights the foam's ability to create a film that spreads over the surface of burning liquid, effectively smothering the fire by cutting off the air supply and preventing the release of flammable vapors. This dual-action capability makes AFFF particularly effective in rapidly suppressing fires and preventing re-ignition.

The other options do not accurately describe the characteristics or functions of AFFF. For example, "Aqueous Foam Fire Filler" and "Aqueous Formidable Fire Foam" are not standard terminologies recognized in firefighting. "Airborne Fire Foam Formation" also misrepresents the purpose and function of AFFF, which relies on the chemical properties of the foam rather than being classified under airborne methods. Understanding the correct terminology is essential in the context of firefighting practices and equipment, emphasizing the importance of AFFF in modern fire suppression strategies.
