What class is the Water Fire Extinguisher used for?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (A)

Water extinguishers are designed to cool and suppress fires involving ordinary combustibles such as wood, paper, cloth, and some plastics. Those fuels fall under Class A. The cooling action of water lowers the temperature of the fuel below its ignition point, stopping the burn. Water isn’t effective for flammable liquids (Class B), electrical fires (Class C), or metal fires (Class D), and can even be dangerous in those situations—it can spread liquid fuels, conduct electricity, or react with certain metals. So the Water Fire Extinguisher is used for Class A fires.
