Which type of fire represents a fuel fire involving solids, such as wood or paper?

The type of fire that involves solids such as wood or paper is classified as a Class A fire. This classification is specifically designated for combustible materials that fall into the category of ordinary combustibles, which primarily include common items like wood, paper, cloth, and some plastics.

Understanding the nature of Class A fires is important for selecting the appropriate extinguishing methods and equipment. For instance, these fires can typically be extinguished using water or foam extinguishers, which effectively cool the burning material and remove the heat necessary for combustion.

Other classifications, such as Class B, involve flammable liquids like gasoline or oil, Class C pertains to electrical fires, and Class D is specific to combustible metals. Each of these types requires different approaches and extinguishing agents, so knowing that Class A fires are linked to common solid fuels is vital for safe and effective fire management.
