Multiple Choice

You can tell the type of metals for which a Class D portable fire extinguisher is approved by doing which of the following?

Metal fires require a specialized agent chosen for the specific metal involved, and the extinguishing capability is listed on the extinguisher itself. The face plate shows exactly which metals the Class D extinguisher is approved to handle, so checking that plate directly tells you the metals it can safely be used on. Using the wrong extinguisher on a metal fire can be ineffective or hazardous, and you don’t determine compatibility by testing, by the numeric rating, or by the nozzle type. The face plate is the official guide to the approved metals.
