In fire classification, what materials are classified as Class A?

Class A materials are those that can be extinguished using water or other agents that cool the burning material. They primarily consist of ordinary combustibles, which include materials such as wood, paper, cloth, rags, and certain types of plastics. This classification is important because it informs the type of fire extinguishing agents that can be effectively used to deal with fires involving these materials.

In contrast, electrical materials, flammable liquids, and fuels like gasoline and oil fall under different classifications due to their unique properties and the specific methods needed to extinguish them safely. For example, Class B materials include flammable liquids and gases, which require specialized extinguishing agents like foam or dry chemical extinguishers that can effectively suppress flames without increasing the risk of spreading. Understanding these classifications is crucial for effective fire safety and response strategies.
