A Class A fire consists primarily of ordinary combustible materials, which include items such as wood, paper, cloth, and certain types of plastics. These materials ignite easily and produce embers that can spread the fire. Understanding that Class A fires relate specifically to these common combustibles is vital for selecting the appropriate firefighting methods and materials. For instance, water and foam extinguishers are typically effective against Class A fires, as they work to cool the burning material and suppress the flames.

In contrast, other classifications—like flammable liquids, flammable metals, and electrical components—fall under different categories of fires, such as Class B, Class D, and Class C, respectively. Each of these classes requires different handling and extinguishing techniques tailored to their unique properties and behaviors when ignited. Being aware of these distinctions ensures a more informed and effective response to various firefighting scenarios.
