Which class of fire is related to common combustibles like wood and paper?

Class A fires are specifically associated with ordinary combustible materials, which include wood, paper, cloth, and some types of plastics. These materials can ignite easily and produce flames that need to be extinguished with water or other agents suitable for such fires. The classification helps fire inspectors and responders to determine the appropriate methods and materials for fire suppression based on the characteristics of the burning substance.

In contrast, Class B fires involve flammable liquids and gases, such as gasoline or oil, which typically require foam or dry chemical extinguishers. Class C fires are related to electrical equipment, necessitating agents that do not conduct electricity, like carbon dioxide or dry chemicals. Class D fires involve combustible metals, which require special extinguishing systems due to the unique hazards posed by those materials. Understanding these classifications is crucial for effective fire management and safety practices.
