the agent being recovered and has a means of visually inspecting the recovered agent for contaminants
11. Halogenated Closed Recovery System: A system that provides for the transfer of halogenated
agents between fire extinguishers, supply containers, and recharge/recovery containers so that none of the halogenat-
ed agent escapes to the atmosphere.

point depressant.
28. Extinguisher service pressure: The normal operating pressure as indicated on the nameplate or
cylinder of a fire extinguisher
29. Factory test pressure: The pressure shown on the nameplate at which a shell was tested at time of
manufacture.
30. wetting agent: A concentrate which, when added to water reduces the surface tension and increases its
ability to penetrate and spread
