Class D fires specifically involve combustible metals. These types of fires can occur with metals such as magnesium, titanium, sodium, and potassium, which can ignite and burn at very high temperatures. Class D extinguishing agents are required to effectively combat these fires, as they react differently than traditional fire extinguishing agents used for other classes of fires.

Understanding that Class D fires are unique is crucial for safety personnel, as improper extinguishing methods (such as using water or foam) could escalate the situation, potentially causing violent reactions or further spreading the fire. By recognizing that Class D pertains specifically to combustible metals, safety protocols and appropriate fire response strategies can be implemented to manage such fire hazards effectively.
