What materials are involved in a "Class B" fire?

"Class B" fires are primarily fueled by flammable liquids and gases. This classification includes materials such as gasoline, oil, grease, and solvents, which can ignite and produce flames that require specific firefighting strategies. The appropriate extinguishing agents for a Class B fire are usually foam, carbon dioxide (CO2), or dry chemical extinguishers, which effectively smother the flames or interrupt the combustion process.

In contrast, other materials listed in the options pertain to different classes of fire. For example, electrical equipment is associated with Class C fires; combustible metals relate to Class D fires; and wood products are examples of Class A fires. Understanding the classifications of fires and the types of materials that cause them helps in selecting the correct firefighting methods and enhancing safety protocols in environments where these materials are present.
