Class A

Class B

Class C

Class D

The type of fire characterized by the combustion of metals is classified as Class D. Class D fires typically involve combustible metals such as magnesium, titanium, aluminum, and sodium. They require special extinguishing agents, as traditional methods like water can exacerbate the situation. Class D fire extinguishers are specifically designed for this purpose and often contain dry powder agents that smother the fire by separating the fuel from the oxygen or by forming a protective layer over the metal. Understanding Class D fires is crucial for safety in environments where these materials are handled or stored, as they present unique challenges compared to other fire classes.
