What type of fire does a Class A fire extinguisher specifically target?

A Class A fire extinguisher is specifically designed to target ordinary combustibles, which include materials such as wood, paper, cloth, and some types of plastics. This classification focuses on common materials that ignite and burn easily in standard conditions. The extinguishing agents used in Class A extinguishers, such as water or foam, are effective in cooling these materials and preventing re-ignition.

Understanding the characteristics of different classes of fire extinguishers is crucial for effective fire safety and response. Class A extinguishers are not suitable for flammable liquids, electrical fires, or combustible metals, as each of these types of fires requires different extinguishing methods and agents for successful suppression.
