A fire involving magnesium turnings would be classified under which specific fire class?

A fire involving magnesium turnings would be classified under Class D. Class D fires are specifically designated for combustible metals. Magnesium is a highly reactive metal that, when ignited, burns intensely and at very high temperatures, often reacting violently with common extinguishing agents like water. This characteristic categorizes it as a combustible metal. Other examples of materials that fall under Class D include titanium, zirconium, sodium, potassium, and lithium, all of which are metals that exhibit similar vigorous combustion properties requiring specialized fire suppression techniques.
