Combustible metals such as titanium and magnesium are typically involved in which type of fires?

Combustible metals like titanium and magnesium fall under Class D fires, which specifically involve flammable metals and certain metal alloys. Class D fires are distinct because they require specialized extinguishing agents, as traditional methods used for other classes of fires (such as water or foam) can actually exacerbate the situation.

These metals ignite at high temperatures and can burn with extreme intensity, often producing metallic oxides. The special characteristics of these fires necessitate the use of dry powder agents specifically formulated for metal fires, which are designed to smother the flames without causing a violent reaction. Understanding this classification is vital for firefighters, as it influences their tactics and safety protocols when responding to incidents involving combustible metals.
