What is a Class D fire?

A Class D fire specifically involves combustible metals, such as magnesium, aluminum, titanium, and sodium. These metals are unique because they react violently with water and can produce flammable hydrogen gas when they come into contact with moisture. Therefore, extinguishing a Class D fire typically requires specialized agents designed for metal fires, like dry powder agents made specifically for such materials.

Recognizing the specifics of Class D fires is crucial for ensuring safety and effective fire suppression, as using water or conventional extinguishing methods on these types of fires can escalate the situation rather than mitigate it. Understanding the characteristics of the materials involved allows for appropriate preparation and response in case of a fire incident involving combustible metals.
