Class D fires involve which materials?

Explanation:
Class D fires involve combustible metals. Metals such as magnesium, titanium, sodium, potassium, and aluminum can ignite and burn fiercely, and some react violently with water or air when finely divided. Because of these properties, they aren’t fought with water or standard foam; instead, special dry powder extinguishing agents or smothering materials like sand are used to isolate the metal from air and absorb heat. This is different from ordinary combustibles (Class A), flammable liquids (Class B), or electrical equipment (Class C), which each require their own suppression approaches.
