1. Purpose
To define the standard procedure for the safe and effective operation of vacuum transfer systems used in elixir manufacturing for transferring raw materials, solvents, or liquid intermediates under reduced pressure conditions. This ensures efficiency, containment, and minimization of product exposure.
2. Scope
This SOP is applicable to all vacuum transfer systems used in the Elixir Department, including fixed-line systems and mobile vacuum pumps, for transferring materials from storage drums or containers to mixing or holding vessels.
3. Responsibilities
- Production Operator:
- Execute vacuum transfer operations following defined procedures.
- Monitor vacuum levels and ensure containment is maintained.
- Production Supervisor:
- Ensure correct setup, readiness of equipment, and verify log entries.
- Engineering Department:
- Maintain and calibrate vacuum gauges, sensors, and vacuum pumps.
- QA Officer:
- Ensure operational verification and compliance with GMP during batch review.
4. Accountability
The Production Head is accountable for the correct use and documentation of vacuum
5. Procedure
5.1 Pre-Operation Checks
- Ensure the vacuum transfer line and system are labeled as “CLEANED” and released for use by QA.
- Check that all gaskets, clamps, valves, and hoses are properly installed and intact.
- Inspect the receiving vessel to confirm it is properly grounded and suitable for vacuum transfer.
- Verify that the vacuum pump and control panel are functional and calibrated.
5.2 Setup Procedure
- Connect the suction line to the source container (e.g., drum or holding tank).
- Connect the discharge line to the receiving vessel.
- Ensure that all valves are in the correct position as per the transfer flow path.
- Use a sight glass or flow indicator to observe flow during operation.
5.3 Vacuum Transfer Operation
- Start the vacuum pump using the control panel.
- Gradually open the suction valve to initiate material transfer.
- Monitor vacuum level (typically between -0.6 to -0.9 bar) and flow rate.
- Ensure that the transfer occurs without interruptions, cavitation, or leaks.
- Observe for foam formation or backflow and stop transfer if any deviation occurs.
- Record the start time, end time, and total volume transferred in the Vacuum Transfer Log (Annexure-1).
5.4 Shutdown and Cleaning
- Close all valves and switch off the vacuum pump.
- Disconnect hoses and drain any residual material using suitable collection containers.
- Clean the vacuum lines, valves, and accessories using the validated cleaning SOP.
- Label the system as “TO BE CLEANED” or “CLEANED” after cleaning completion.
5.5 Safety and Precautions
- Always wear PPE including gloves, goggles, and apron during transfer.
- Ensure the system is leak-free and vacuum-rated before applying negative pressure.
- Use anti-foam agents if specified in the BMR to avoid frothing during transfer.
- Never bypass safety interlocks or operate the system with broken seals.
