What type of fires does Class A represent?

Class A fires pertain specifically to ordinary combustibles, which include materials such as wood, paper, cloth, and certain types of plastics. These are typically found in everyday environments and are common sources of fire. The extinguishing agents for Class A fires are usually water or foam, as they work effectively to cool the burning materials and smother the flames.

Understanding the classification of fires is vital for preventing and responding to fire emergencies, particularly in high-rise buildings where different materials are present. Recognizing that Class A covers ordinary combustibles allows Fire Safety Directors and personnel to identify the right fire suppression methods and equipment needed in case of such incidents, ensuring a quicker and more efficient response to fires involving these materials.
