Class D fires involve which type of materials?

Class D fires specifically involve combustible metals, including materials like aluminium, magnesium, and sodium. These types of fires behave differently than those involving flammable liquids, gases, or electrical apparatus because they can react violently with water and require specialized extinguishing agents to control.

Fire extinguishers for Class D fires typically use dry powder agents specifically designed for metal fires, as traditional methods like water can exacerbate the situation. Understanding the unique characteristics of Class D fires is crucial for effective fire safety management and response, underscoring the importance of recognizing the materials that fall into this category.
