For Class D fires, what agent is typically used?

For Class D fires, which involve combustible metals such as magnesium, sodium, or potassium, the typical extinguishing agent used is a dry chemical specifically designed for such situations. Dry chemical agents are effective because they smother the fire and displace oxygen, preventing the fire from spreading and helping to cool the burning material.

The nature of Class D fires requires careful management because traditional agents like water can react violently with burning metals, potentially causing explosions or increasing the fire's intensity. The chosen agent must be able to effectively control and extinguish the flames without introducing additional hazards. Therefore, dry chemical agents are formulated to handle such materials safely, making them the most suitable option for effectively fighting Class D fires.
