Aqueous Film Forming Foam (AFFF) is designed to form a barrier on the surface of flammable liquids, preventing oxygen from reaching the fuel. The correct application method is to allow the foam to gently rain down onto the fuel surface, which helps in creating a continuous film over the fuel without disturbing it. Direct application or agitation can break the foam blanket, compromising its effectiveness.
