Combustable+Metals

General Laboratory Safety Combustible Metals Do you have any combustible metals or combustible metal compounds in your welding shop? If so, you will need to have a type D fire extinguisher. In the event of a fire, types A, B, and C fire extinguishing agents will react with combustible metals. Therefore, unique agents such as potassium and sodium are used in type D fire extinguishers to put out fires with combustible metals. Type D fire extinguishers are yellow and have a five pointed star on them. Please call DPS at 3-1131 if in need of this type of fire extinguisher. The following is a list of combustible metals that require a type D fire extinguisher: calcium

cerium

cesium

lithium

lutetium

**magnesium and magnesium alloys**

neodymium

phosphorus

potassium

potassium-sodium alloys

rubidium

sodium

strontium
