Which class of fire deals with metals and metal powders?

The classification of fires is based on the type of material that is burning, and understanding these classifications is crucial for selecting the appropriate firefighting equipment.

Class D fires specifically involve combustible metals, which can include substances such as magnesium, titanium, sodium, and potassium. These metals behave differently when involved in a fire compared to other materials. For instance, they can burn at extremely high temperatures and may react violently with water or other chemicals. Therefore, specialized extinguishing agents, often specific to the type of metal, are required to safely manage Class D fires.

The correct recognition of the Class D category is vital for safety in environments where such materials are present, as using the wrong type of fire extinguisher could exacerbate the situation. Understanding this classification not only helps in firefighting but also plays a critical role in implementing safety measures in workplaces that handle these types of materials.
