Which class involves combustible metals such as aluminum?

• A. Class A Fires
• B. Class B Fires
• C. Class C Fires
• D. Class D Fires

Answer: (D)

Fires involving combustible metals are treated as a separate category because metals burn differently and require specialized extinguishing methods. Aluminum is a metal that can ignite and burn at high temperatures, so it fits into the metal fires category. To put these flames out, use a dry powder extinguishing agent designed for metal fires, or smother with a noncombustible material like sand to cool and isolate the fuel. Water or standard foams are not suitable here because they can react with the metal or spread the fire. Other fire classes cover ordinary combustibles (like wood or paper), flammable liquids, or energized electrical sources, which do not apply to metal fires.
