What characterizes Class D fires?

Class D fires are specifically characterized by the involvement of combustible metals. These types of fires are unique because they involve materials that burn at high temperatures and can react violently with water and other extinguishing agents. Common materials in Class D fires include magnesium, titanium, and sodium, all of which require specialized firefighting techniques and agents for effective control and extinguishment.

Understanding the nature of combustible metals is crucial for fire safety personnel, as the wrong approach, such as using water, may exacerbate the situation instead of resolving it. This knowledge is essential when responding to incidents involving these metals, making it imperative for those trained in fire safety to recognize the distinct properties and behaviors of Class D materials.
