• The sterile SCDM shall be issued from micro department to production department.
• The non-viable air borne particle counts of the critical area; temperature, relative humidity and differential pressure of the area shall be checked and recorded.
• The garments used in filling area are cleaned and washed in washing machine, inspected, wrapped and then sterilized in the sterilizer as per the validated sterilization cycle as per loading pattern. After the sterilization is over the sterilized garments are transferred to the garment cubicle, located in change room III.
• Rubber stoppers are sterilized in the sterilizer as per the validated sterilization cycle as per loading pattern. After the sterilization is over the sterilized rubber stoppers are transferred to filling area should be used for media fill.
• The vials are decartoned in Decartoning room, inspected through conveyer belt, washed through the vial washing machine and the washed vials are depyrogenated in Sterilization and depyrogenation tunnel.
• The washed and sterilized machine parts transferred in vial filling and stoppering machine by using mobile LAF. The sterilized and depyrogenated vials get collected & loaded on in feed turntable of the vial-filling machine.
• The sterilized rubber stoppers are charged into hopper and raw material is transferred into the sterile container is attached to the hopper. WFI is filled in each vial by using media filling assembly.
• The filled weight is adjusted of each filling station as per the fill weight mentioned in BMR and Weights of vials from all the filling stations and the average weight shall be checked and recorded at regular intervals.
• Filled and stoppered vials are sealed on vials sealing machine. The sealed vials are then checked on line visually for any defect. Defective vials are collected separately and good vials are allowed to move forward to collect in tray.
• After completion of the batch raw material and primary packing material are reconciled, batch yield are calculated and recorded in the batch manufacturing record (BMR), Batch analysis reports and other supporting documents shall be attached with BMR.
• The BMR is sent to the QA for review.

The positive control vials shall be used within 15 days after incubation.
• The positive and negative control vials shall be prepared for each vial size and kept in microbiology lab and shall be used during visual inspection of Media filled vials as a reference.

7.14     INTERPRETATION OF RESULTS
