What is the main application of class D fire extinguishers?

Class D fire extinguishers are specifically designed for extinguishing fires that involve combustible metals, such as magnesium, titanium, and sodium. These types of fires can burn at extremely high temperatures and may react violently with water or other common firefighting agents, making it crucial to use extinguishing agents that are suitable for these materials.

The extinguishing agents used in Class D extinguishers are typically dry powders that can smother the fire and do not react adversely with the burning metals. This tailored approach ensures effective fire control where other extinguishing methods could fail or worsen the situation. Understanding the correct application of Class D extinguishers is vital for safety in environments where combustible metals are present, such as metalworking industries or laboratories.
