i have a doubt, reg. facility shutdown.
what are the measures to be taken during resume of clean room facility after a period of shutdown (one day, one week, one month)
does viable and non viable monitoring for one day n one time is enough for clearance.
is there any reference documents for this[/quote]
It is better to do decontamination process with a validated process (the decontamination process may include fumigation, cleaning with disinfectants etc.). If you have the validated process of decontamination then one time testing of your decontamination process is enough for clearance.
