I am currently taking over the environmental program at my facility but don't have too much experience on compressed air.
In the past we have been using a 3rd party lab to test every 4 months with ranges less than or equal to 10 CFU for Aerobic plate count, Yeast, and Mold.
I tested last week and got results that were way higher than that and i was wondering if my ranges made sense or if it had to do with the fact that in the past they used sponge testing and this time i used plates. Can someone help me out?
What do your compressed air programs look like?
