Combustible Metals
List of Combustible Metals or Metal Compounds:
If your laboratory contains combustible metals or combustible metal compounds, 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. The following is a list of combustible metals that require a type D fire extinguisher:
| aluminum phosphide aluminum (powder) beryllium (powder) calcium calcium carbide cerium cesium gallium arsenide gallium phosphide lithium lithium aluminum deuteride lithium aluminum hydride lithium aluminum hydride bis(tetrahydrofuran) lithium amide |
lithium borohydride lithium-6 deuteride lithium hydride lithium tetraphenylborate tris(1,2-dimethoxyethane) lithium tri-tert-butoxyaluminohydride lutetium magnesium hydride magnesium and magnesium alloys neodymium nickel catalyst (Raney) phosphorus phosphorus pentasulfide potassium potassium hydride |
potassium-sodium alloys Red-Al rubidium sodium sodium aluminum hydride sodium bis(2-methoxyethoxy)aluminum hydride in toluene sodium borohydride sodium borohydride cobalt-doped sodium borohydride on alumina sodium hydride strontium titanium (powder) zinc phosphide zinc (powder) zirconium (powder) |
