221. A stored-pressure water extinguisher is most effective against which class of fires?
Stored-pressure water extinguishers are designed for Class A fires involving ordinary combustibles. Water cools and soaks these materials to extinguish the fire. Other fire classes require different extinguishing agents due to the risks of spreading flammable liquids, electrical shock, or violent reactions with combustible metals.
