Class A fires typically involve which of the following?

Class A fires involve common combustibles such as paper, wood, textiles, and certain types of plastics. These materials are solid in nature and can ignite easily, producing ash or embers as they burn. The fire suppression tactics for Class A fires often include the use of water or foam to cool the materials and remove heat from the fire, which is effective because these types of fires primarily rely on a solid fuel source. Understanding the nature of Class A fires is crucial for effective firefighting tactics, as different classes of fires require different methods of extinguishment.
