The type of fire extinguisher specifically designed to combat fires involving combustible metals is Type D. These fires can occur with metals such as magnesium, titanium, sodium, and potassium, which pose unique challenges due to the high temperatures and reactions they produce when ignited. Type D extinguishers use dry powder agents that are effective in smothering and controlling these metal fires without causing further reactions or hazards.

Type A extinguishers are suitable for ordinary combustibles like wood and paper, while Type B extinguishers are intended for flammable liquids and gases. Type C extinguishers are used for electrical fires. Each of these types serves a distinct purpose and is designed for specific classes of materials, which is why they would not be effective against combustible metal fires. Type D extinguishers are crucial for safely managing the unique hazards presented by these materials.
