Hi Guys,
Back again to pick your brains.
We have a class VII cleanroom, approx. 4.5m x 4.5m.
We perform environmental monitoring on a monthly basis, "at rest".
Air plates, settle plates and contact plates.
Our limits are as follows:
Air Plates in Cleanroom - 100 (cfu/mould per m^3)
Air Plates in Airlock - 200
Settle Plates in Cleanroom - 100 (cfu/mould per plate)
Settle Plates in Airlock - 200
Contact Plates in Cleanroom - 25 (cfu/mould per 24cm^2)
Contact Plates in Airlock - 50
I know we should be testing while in use which is what we plan to do shortly.
However, I have been asked to set alert limits (below the above limits) and I have been unable to find any helpful information regarding any formula or method to define these limits.
Can anybody help?
