Combustible Metals

 

Type D

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
