In fire terminology, which class is associated with combustible metals?

In fire terminology, Class D is specifically designated for combustible metals. This classification is critical because metals such as magnesium, titanium, and sodium can ignite and burn at very high temperatures, often producing dangerous and challenging-to-extinguish fires. Water and standard extinguishing agents are generally ineffective against such fires and can sometimes exacerbate the situation. Therefore, special extinguishing agents, such as dry powder agents specifically designed for metal fires, are required to handle Class D fires safely and effectively.

Other classes serve different categories of materials. For example, Class A is for ordinary combustibles like wood and paper, Class B covers flammable liquids and gases, and Class C is for electrical fires. Understanding the distinction between these classes is essential for effective fire prevention, response strategies, and safety protocols within fire investigation and firefighting practices.
