AFFF stands for which term?

• A. Aqueous Film-Forming Foam
• B. Alcohol-Forming Film Foam
• C. Aqueous Flame-Forming Foam
• D. Alkaline Film-Foam Firefighting

Answer: (A)

Aqueous Film-Forming Foam is a water-based foam used on hydrocarbon fires. The term breaks down into: Aqueous, meaning water-containing; Film-Forming, describing how the foam spreads to create a thin layer on the fuel surface that cools the liquid and blocks vapor from air; and Foam, identifying the foaming agent itself. This combination provides rapid knockdown and vapor suppression, which is why it’s widely used for fires involving flammable liquids, such as aircraft hangars. The other phrases don’t match the established name or describe the same properties.
