Which class of fire involves combustible metals such as magnesium and sodium?

Class D fires specifically involve combustible metals like magnesium, sodium, potassium, and other reactive metals. These types of fires are unique because they cannot be extinguished using conventional methods, such as water or foam, which may react with the burning metal and exacerbate the situation. Instead, specialized extinguishing agents that are designed for Class D fires, such as dry powder agents, are used to smother and cool the burning metals effectively.

Understanding the characteristics of Class D fires is crucial for fire safety and fire prevention, particularly in industrial environments where these metals may be present. Proper training and knowledge about how to handle Class D situations ensure that fire inspectors can effectively manage risks associated with combustible metals and employ the appropriate firefighting techniques when necessary.
