Hi,
I had a quick question regarding how my job has set up their cleanroom monitoring plan. At the moment, the differential pressure is quantitatively defined once a year during our cleanroom re-certification. In the ISO 14644-2, it says "the pressure differential may be monitored by periodic observation or by automated instrumentation." We don't quantify the pressure ever, but we are supposed to daily check if there is air flow out of the cleanroom grill with our hands. Is that a common practice/ in compliance? Does this require an alert and action limit, and if so, how do we feasibly do that if we don't have much data. I don't necessarily know what they mean by 'periodic observation' and I want to make sure we aren't behind when it comes to how everyone else does it.
Thank you!
