AFFF stands for:

• A. Aqueous Film-Forming Foam
• B. Alcohol-Forming Foam
• C. Aqueous Forming Film Foam
• D. Aluminum Film-Forming Foam

Answer: (A)

Aqueous Film-Forming Foam is the standard term for a water-based foam that rapidly blankets hydrocarbon fuels and forms a protective film. This film spreads across the fuel surface, separating fuel from air and cooling the mixture, which helps suppress the fire and prevents reignition. The other phrasings are not correct because they either swap or replace key elements (alcohol instead of aqueous), or mix up the words (film and forming), or introduce a term not used in firefighting foam terminology (aluminum). So the accurate name is Aqueous Film-Forming Foam.
