Class A is the most common type of fire involving ordinary combustible materials such as wood, cloth, paper, rubber, and many plastics. This type of fire leaves an ash behind after burning and has an ember flame. The most common and the most effective extinguishing agent for them is generally water in the form of a jet or a spray. Water is used in a cooling or quenching effect to reduce the temperature of the burning material below its ignition temperature.

Class B fires are the ones involving liquids or liquefiable solids. A flammable liquid must be burning at room temperature in order to be a Class B fire, and a combustible liquid must be heated to its flammable point to be classified as Class B. Some flammable and combustible liquids included in this classification are petroleum, tars, oil-based paints, oil, alcohols and lacquers.
