A stored-pressure water extinguisher would be best used on a which class of fire?

Explanation:
Stored-pressure water extinguishers work by absorbing a lot of heat from the flame, cooling the fuel below its ignition temperature so the fire cannot continue. This makes them ideal for ordinary combustibles like wood, paper, and cloth. They are not suitable for flammable liquids, electrical fires, or reactive metals, where water either spreads the fire, conducts electricity, or reacts dangerously with the material. So the best use is on fires involving ordinary combustibles.
