Which class of fire extinguisher is suitable for fires involving wood, paper, and trash?

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

Answer: (A)

The suitable class of fire extinguisher for fires involving wood, paper, and trash is Class A. Class A fire extinguishers are specifically designed to combat fires fueled by ordinary combustibles such as wood, paper, cloth, rubber, and some types of plastics. The extinguishing agents in Class A extinguishers, typically water or foam, effectively cool and extinguish these types of fires. This makes Class A extinguishers the correct choice for such materials. In contrast, Class B extinguishers are intended for flammable liquids and gases, such as oil, gasoline, or paint. Class C extinguishers are suitable for electrical fires and are typically non-conductive, often using carbon dioxide or dry chemical agents. Class D extinguishers are designed for flammable metals, which require specialized extinguishing agents due to the unique characteristics of metal fires. Understanding the specific classes of fire extinguishers and their applications is crucial for ensuring safety when dealing with different types of fire hazards.
