Which class of fire is associated with combustible metals?

The classification of fires is based on the materials involved, which dictates the appropriate extinguishing methods. The D-Class fire is specifically associated with combustible metals such as magnesium, titanium, potassium, and sodium. These types of fires require special handling due to the unique properties of the metals involved; for instance, they can burn at very high temperatures and may react violently with water or foam, which are commonly used in other classes of fires.

Extinguishing agents for D-Class fires often include dry powder agents that smother the fire without causing a reaction, thereby preventing it from worsening. This distinction is crucial for firefighting strategies, as using the wrong type of extinguishing agent can exacerbate the situation.

Therefore, D-Class is the correct classification for fires involving combustible metals. Understanding this classification is essential for ensuring safety and effectiveness in handling such incidents.
