At-Rest (Cleanroom)

European Community (EC) defines “at rest” state as “the condition where the installation is complete with production equipment installed and operating but with no operating personnel present”. The Medicines Inspectorate, however, further clarifies, “It should normally be taken to mean that ventilation systems are operating and other equipment is present in an operational condition but not in use”.
