Class A fires typically involve which of the following materials?

Class A fires are primarily associated with ordinary combustibles, which include materials such as textiles, paper, and wood. These materials are characterized by their ability to burn readily and produce ash, making them the primary focus when responding to Class A fire incidents.

In a firefighting context, understanding the types of materials that classify fires helps firefighters employ the correct extinguishing agents and tactics. Water is often the most effective method for extinguishing Class A fires, as it cools the material below its ignition point and can effectively absorb heat, addressing the fire's need for oxygen and maintaining combustion.

The other material categories mentioned, like metals, electrical equipment, and fuels, fit into different fire classifications. For instance, metals may be involved in Class D fires, and electrical equipment is primarily associated with Class C fires. Fuels are a broader category that could apply to various fire types depending on their specific characteristics and behavior during combustion.
