Which of the following is true about AFFF?

Aqueous Film Forming Foam (AFFF) is known for its unique properties that make it effective in firefighting, particularly against flammable liquid fires. The statement regarding AFFF forming a film that suffocates fire highlights one of its key functions. When AFFF is applied to a fire, it spreads across the surface of burning liquids, creating a thin film that excludes oxygen from the fuel. This action is crucial because most fires require oxygen to sustain combustion. By denying the fuel access to oxygen, AFFF effectively smothers the fire, leading to its extinguishment. In contrast, while AFFF can be effective against various classes of fires, it is not specifically designed for Class A fires alone, nor is it effective against electrical fires, as certain precautions must be taken in those situations. Additionally, AFFF is not suitable for all fire types, meaning it has specific applications and limitations based on the type of material that is burning. Thus, the correct assertion about AFFF relates directly to its ability to create a film that suffocates fire, which is a fundamental characteristic of this firefighting agent.
