What does AFFF stand for?

• A. Aerial Foam Film-Forming Foam
• B. Alkaline Film-Forming Foam
• C. Aqueous Film-Forming Foam
• D. Acid Foam-Forming Foam

Answer: (C)

Aqueous Film-Forming Foam stands for AFFF. It’s a foam concentrate used on hydrocarbon fires, especially in aircraft rescue and firefighting. When mixed with water, it creates a foam that rapidly blankets the fuel surface and forms a thin, continuous film over the liquid. This film lowers surface tension and acts as a barrier between the fuel and air, allowing for quick knockdown, cooling, and reduced vapor release to prevent reignition. The term reflects a water-based solution (aqueous) that forms a protective film (film-forming) and is used as a foam concentrate (foam). The other options don’t match the established terminology or function of this foam agent.
