What class of fire involves the combustion of timber and other organic solids?

The combustion of timber and other organic solids is classified as a Class A fire. Class A fires primarily involve ordinary combustibles, such as wood, paper, cloth, rubber, and many plastics. These materials have a consistent characteristic of burning with glowing embers, which makes them different from other types of flammable materials.

Understanding fire classes is crucial for effective firefighting. Class A fires can be extinguished using water, foam, or multipurpose dry chemicals, as these agents can cool and smother the flames. The identification of the fire class helps in choosing the appropriate fire extinguishing method and ensures the safety of personnel and the environment in the event of a fire outbreak in areas where timber and organic materials are present.
