What kind of fire does Class D represent?

Class D fires are specifically associated with flammable metals, such as magnesium, titanium, and potassium. These types of fires require special extinguishing agents, often dry powders, that can smother the flames and cool the burning material without reacting negatively with it. Unlike other classes of fire, which may involve typical combustible materials, Class D fires demand a distinct understanding of the characteristics of the metals involved and the methods effective against them. Recognizing this classification helps firefighters employ the correct techniques and agents during a fire incident involving combustible metals to ensure safety and effectiveness in suppression efforts.
