Which type of fire extinguisher is best suited for wood, paper, cloth, plastic, and rubber fires?

The correct choice is tailored specifically for Class A fires, which involve ordinary combustible materials such as wood, paper, cloth, plastic, and rubber. Class A fire extinguishers are designed to combat these types of fires effectively because they typically contain water or foam, which can cool the burning materials and help to extinguish the flames.

Using a Class A extinguisher on Class A fires is essential because it addresses the nature of the fire, allowing for effective suppression. The extinguishing agents used in Class A extinguishers are capable of penetrating and soaking into the burning materials, helping to prevent rekindling by cooling the substances involved in the fire.

Other classes of extinguishers are intended for different types of fires: Class B extinguishers are used for flammable liquids, Class C for electrical fires, and Class D for combustible metals. Each class is designed to target specific fire types, and using the correct type is critical for safety and effectiveness.
