A water extinguisher is suitable for which class of fire?

Explanation:
Water extinguishers work primarily by cooling the burning material, which makes them effective for ordinary combustibles like wood, paper, and textiles. These fuels define Class A fires, so a water extinguisher is suited for Class A. It’s not appropriate for fires involving flammable liquids or energized electrical equipment, because water can spread the liquid and can conduct electricity, posing safety risks. So the best match is Class A fires.
