Combustible metals are classified under Class D fires. This classification specifically refers to fires that involve flammable metals such as magnesium, titanium, zirconium, and sodium. Class D fires can be particularly hazardous, as these types of metals can burn at very high temperatures and may react violently with water or other extinguishing agents.

Fire extinguishers designed to combat Class D fires typically use dry powder agents that smother the flames and cool the burning metal. In contrast, Class A fires involve ordinary combustibles like wood and paper, Class B fires involve flammable liquids, and Class C fires involve electrical equipment. These categories are essential for selecting the appropriate firefighting techniques and extinguishing agents to ensure safety during a fire emergency.
