Dear Khun JAR
Per discussion with Khun Phichet and Khun Prasert.
Guidelines for follow up CA/PA and efficiency verification as detail below :
First step : 1) I informed to MFG department add item about the cleanliness of the loading tubes on preventive maintenance plan. (such as 1 time/year as appropriate)
2) MFG should be prepare SOP or WI for cleanliness of the loading tubes.
3) MFG should be prepare checklist for daily checking such as total dust/dirty etc.
4) Training or inform information is work instruction, SOP, Checklist about the cleanliness of the loading tubes to operators and supervisors or all concerned by chief manager.
Second step : ISO and auditor team auditing and monitoring on Internal Audit time.( 2 time/Year)
And last step : If found non-conforming requirement, Auditor can issue CPAR to all concerned immediately.
Thank you for your consideration. Please review and comment as detail and feel free adjust.
Best Regards,
Nittaya
