What kind of fire is caused by flammable metals according to the fire classification?

Fires caused by flammable metals are classified as Class D fires. This classification specifically refers to fires involving combustible metals such as magnesium, titanium, and sodium, which can react violently with water and require specialized extinguishing agents. Class D fire extinguishers typically use dry powder agents designed to smother the fire and absorb heat, effectively preventing combustion. Understanding this classification is crucial for safety protocols, especially in environments where metalworking or similar operations occur, as improper handling can lead to hazardous and challenging fire situations.
