Which class of fire involves combustible metals?

Class D fires specifically involve combustible metals, such as magnesium, titanium, and sodium. When these metals catch fire, they can burn at extremely high temperatures and require special extinguishing agents that are designed to handle their unique properties. Water or common extinguishing agents are ineffective against Class D fires because they can react dangerously with the metal, potentially causing explosions or spreading the fire.

Understanding the specific nature of Class D fires is crucial for anyone working in environments where such materials are present. Proper training in using the right type of fire extinguisher designed for Class D materials can make a significant difference in controlling and extinguishing these fires safely. The other classes of fires (A, B, and C) pertain to ordinary combustibles, flammable liquids, and electrical fires, respectively, and do not involve the unique challenges posed by combustible metals.
