Which class of fire involves combustible metals like magnesium and titanium?

The classification of fires is essential for determining the appropriate extinguishing method. Fires involving combustible metals such as magnesium and titanium fall under the category of Delta class fires.

Delta class fires are specifically characterized by the presence of flammable metals that can ignite and burn at very high temperatures. These types of fires require specialized extinguishing agents, as conventional methods such as water will often exacerbate the fire or lead to dangerous reactions. Firefighting techniques for Delta class fires may include using dry powder extinguishers, which are designed to suppress metal fires without causing further reactions.

Understanding this classification is crucial for safety and effective fire response, particularly in environments where such metals are present.
