Class B foam is intended for use on which type of fuels?

Explanation:
Class B foam is designed for flammable liquids, specifically hydrocarbons such as gasoline, diesel, kerosene, and oil-based solvents. It works by forming a foam blanket that floats on the surface of the liquid, cooling the fuel and separating it from the air to suppress vapors. This barrier prevents ignition and helps prevent reignition. It isn’t suited for electrical fires, metal fires, or water-based materials, which require different extinguishing approaches.
