Using the wrong extinguishing agent on a Class D fire may cause more damage than the fire itself. Other than the extreme threat that all metal fires pose, one common characteristic is that all of them react violently, often exploding, when they come in contact with water.
So what is the solution to a raging metal fire?
The National Fire Prevention Association (NFPA), a panel of experts on fire safety and prevention, recommends Dry Powder extinguishing agents. These extinguishing agents have a blanket-effect on the fire and smother the flames by absorbing the heat.
