Fires resulting from combustible metals are classified as which class?

Fires involving combustible metals, such as magnesium, titanium, or sodium, are classified as Class D fires. This classification is specifically designated for fires that occur with metals that can ignite and burn independently of oxygen, and which often require special extinguishing agents such as dry powder agents to effectively put them out. Class D fire extinguishers are designed to handle this type of fire because typical water or foam extinguishers can react violently with burning metals, worsening the situation.

Understanding this classification is crucial because it informs the appropriate response and safety measures to take when dealing with such incidents. The other classes—Class A for ordinary combustibles like wood and paper, Class B for flammable liquids, and Class C for electrical fires—do not encompass the unique characteristics and materials involved in Class D fires. Thus, knowing that combustible metal fires fall under Class D helps individuals and professionals take more informed actions in fire safety and management.
