As I asked you for more detail to clear, you informed me that Aeaw informed you kept air after complete air fogging 30 mins, but its condition still had chemical , was not removed air out after complete fogging. This is the result that why micro result was passed for this round. This result is not correct, the correct you have to keep air after complete remove all chemical in filling room.
Next round , don’t do this. If any change has to inform me, don’t do as the supplier informed. We have to do as the first round for comparing the result.
Next round, please keep air after remove all chemical and keep air monitoring every 24 hr until next CIP chemical (Line1 =120 hr, Line4 and Line6 = 72 hr). We need the result 3 times with the same condition to ensure that air fogging effectiveness.
