D Class Fire Extinguishers
Class D fires are those involving burning metals. This type of fire can be found anywhere there are metal “fines,” filings or particles including metal fabrication facilities, warehouses, labs, and factories. Not all metals are flammable, but those that are can be very difficult to extinguish once they start to burn.
Most often, these fires involve magnesium and titanium, but they can also involve:
- Sodium-potassium alloys
To put out combustible metal fires, a Class D dry powder extinguisher is the only recommended option. When used properly to extinguish a metal fire, the agent in a D-rated fire extinguisher will form a crust over top of the fire to absorb the heat and smother the fire robbing it of oxygen and preventing it from spreading. We offer 30-LB Class D extinguishers from Amerex with an operating temperature range from -40°F to 120°F with a six-year warranty. Extra care and consideration need to be taken when dealing with metal fires. If you choose the wrong extinguishing option, it can quickly make the fire much worse. It’s also important to remember that different metals may require different extinguishing agents. Additionally, these dry powder extinguishers should not be confused with dry chemical (multi-purpose) fire extinguishers. We can help you choose the right fire extinguisher for your needs.
