The class of fire associated with combustible metals is Class D. This classification specifically pertains to fires involving flammable metals such as magnesium, titanium, and sodium. Class D fires require specialized extinguishing agents, as conventional methods used for other classes of fires may be ineffective or even dangerous.

For instance, using water on a Class D fire can lead to violent reactions and an explosive dispersion of burning metal particles. Instead, materials like dry powder agents are utilized for extinguishing these fires, as they can effectively smother the flames and prevent re-ignition. Knowing this distinction in fire classes is crucial for ensuring safety procedures and fire response protocols are appropriate for the materials involved.
