Which class of fire extinguisher is most commonly used for combustible materials such as wood and paper?

The Class A fire extinguisher is specifically designed to combat fires involving combustible materials like wood, paper, cloth, and certain types of plastics. These materials ignite easily and can create highly flammable situations, so it’s crucial to utilize a fire extinguisher that is effective against such fires.

Class A extinguishers typically contain water or foam agents, which cool the burning materials and help to smother the flames. The effectiveness of Class A extinguishers against ordinary combustibles makes them a fundamental resource in environments where such materials are present, such as homes, offices, and workshops.

In contrast, the other classes of extinguishers cater to different types of fires. Class B extinguishers are for flammable liquids like gasoline and oil; Class C extinguishers are designed for electrical fires; and Class D extinguishers are for combustible metals. Each type is tailored to address specific fire risks, so using a Class A extinguisher for Class A materials is essential for effective fire control and safety.
