What type of materials are involved in Class D fires?

Class D fires specifically involve reactive metals, which can include elements such as magnesium, titanium, sodium, and potassium. These materials require specialized extinguishing agents due to their unique combustion characteristics. For instance, when reactive metals ignite, they can react violently with water or other common extinguishing agents, making it crucial for firefighters and safety personnel to be trained in the specific procedures for handling such fires.

The other material types listed pertain to different classes of fires. Flammable liquids fall under Class B, which includes oils, gasoline, and solvents. Electrical equipment is categorized as Class C fires, and wood and paper are associated with Class A fires. Understanding these distinctions is vital for effectively responding to different fire scenarios. In the case of Class D fires, the focus is primarily on those materials that can undergo combustion in ways that are significantly different from typical combustible or flammable materials.
