Foam is effective at extinguishing class B fires, which involve flammable liquids such as gasoline, oil, and solvents. It works by forming a blanket over the burning liquid, smothering the flames and preventing oxygen from reaching the fuel. Additionally, foam can also be used on class A fires involving ordinary combustibles like wood and paper, but its primary application is in liquid fire scenarios.
