What is use of foam limited to?

Explanation:
Foam is designed to fight fires involving flammable liquids by forming a thick blanket that cools the liquid and separates the fuel from the air, suppressing vapors and slowing spread. Because its primary purpose is to control fires caused by combustible liquids, its use is limited to combustible materials. It’s not intended for water surfaces, since there’s no fuel to blanket, and it’s not the right tool for fires involving noncombustible metals or energized electrical equipment, where different extinguishing approaches are required.
