The four classes of fire extinguishers are placed in Class A, Class B, Class C and Class D. Class A extinguishers are for ordinary materials such as paper, plastic and wood. Class B fires are those containing flammable liquids are involved. These fluids gasoline, kerosene or oil. Class C fires are electrical fires related. The use of water from these types of fires can be dangerous, because the risk of electric shock is possible. Class D fires, chemical fires caused by combustible metals. Class D fires are usually found in chemical laboratories, and should not be a source of concern for the average home.
