Which class of fire involves combustible metals?

The classification of fires is based on the type of materials that are burning. Class D fires specifically involve combustible metals, which include materials like magnesium, titanium, and sodium. These metals react differently to fire, often burning at extremely high temperatures and may even react violently with water or other common extinguishing agents.

In contrast, Class A fires involve ordinary combustibles such as wood, paper, and textiles; Class B fires are related to flammable liquids like gasoline and oil; and Class C fires involve energized electrical equipment. Each class requires different types of fire extinguishers and approaches for effective fire suppression. Therefore, understanding that Class D is the correct classification for fires involving combustible metals is crucial for effective response in fire emergencies involving such materials.
