particle validation in cleanrooms

Hi
would you tell me how many times do you do particle counting during one batch production in class A? completly during the production time or just at the beggining, at the middel an at the end of production?
at GMP we had to do counting all the time of production and I think it’s impossible to do that for about 8 hours!
thanks

I do not work only 8 hours ;).
but seriously, what is the size of room?

except that it is a device, this monitoring should be carried out continuously
