Firefighting foam

Firefighting foam is a substance used to extinguish fires, especially those involving flammable liquids such as oil and gasoline. It works by forming a barrier between the fuel and the fire, effectively suppressing the flames and preventing the release of flammable vapors. Firefighting foams generally consist of three main components: a foam concentrate, water, and, in some cases, air. The foam concentrate is mixed with water to create the foam solution.
