ensuring that all utility systems are maintained and in proper working condition after process changes.

Quality Assurance (QA) Team: Responsible for reviewing and approving all verification documentation to ensure compliance with GMP and regulatory standards.

Production Team: Responsible for assisting in the verification process and reporting any issues or abnormalities in utility systems during production following a process change.

4. Accountability

The Manufacturing Manager is accountable for ensuring that the utility system verification process is performed after any process changes. The overall compliance with this SOP is overseen by the Quality Assurance (QA) Manager.

5. Procedure

5.1. Preparing for Verification of Utility System Performance

1. Review the process change details and identify which utility systems may be impacted by the change. This may include changes in production requirements, equipment modifications, or regulatory updates.
2. Ensure that all necessary equipment for verifying utility system performance is available and calibrated. This includes pressure gauges, flow meters, temperature sensors, and any other testing instruments required for performance verification.
3. Establish the verification team, which should include representatives from Engineering, Production, and QA teams. All personnel involved in the verification process should be trained in the relevant procedures and standards.
4. Determine the specific performance parameters for each utility system that need to be verified following the process change. These may include pressure, flow rates, temperature, contamination levels, and system integrity.

5.2. Verifying Utility System Performance

1. The verification process should include the following key steps for each affected utility system:
   • Water Systems: Verify that water flow rates, pressure, and temperature are within the acceptable ranges. Perform microbial and particulate testing to ensure that water quality is maintained.
   • Compressed Air Systems: Verify that the compressed air pressure and flow rate are within the specified limits. Perform contamination testing to ensure that no particulate matter or oil is present in the system.
   • Gas Systems: Verify that gas pressure and flow rates are within the required ranges. Perform gas purity testing to ensure that no contaminants are present in the gas supply.
   • HVAC Systems: Verify that the HVAC system is maintaining the required temperature and humidity levels. Perform airflow and filtration efficiency testing to ensure compliance with the specifications.
2. Perform the necessary tests for each system under normal operating conditions to confirm that the system continues to meet the required performance standards after the process change.
3. Record all test results, including pressure readings, flow rates, temperature, contamination levels, and any deviations observed during testing. Document the results in the Utility Performance Verification Report (Annexure-1).

5.3. Documenting the Verification Results

1. Document the following information in the Utility Performance Verification Report (Annexure-1):
   • Utility system ID, model number, serial number, and installation location
   • Details of the process change and its potential impact on utility systems
   • The test methods, results, and comparison with acceptable limits
   • Any deviations observed and corrective actions taken
   • The name and signature of the personnel performing the verification tests
   • Approval signatures from the QA team
2. Ensure that all data entries are legible, accurate, and supported by the necessary calibration and testing equipment used during the verification process.

5.4. Reviewing and Approving the Verification Report

1. The QA team should review the Utility Performance Verification Report to ensure that all verification activities were carried out according to SOP requirements, and that the utility systems are performing within the required specifications.
2. If any deviations are found, they should be documented in the Deviation Log (Annexure-2), and corrective actions should be taken to address the issues.
3. Once the verification report is complete and all deviations have been addressed, the QA team should approve the report.

5.5. Finalizing the Verification Process

1. After the verification process is completed and the utility systems are confirmed to be operating within the specified parameters, the systems are cleared for use in the production process.
2. Ensure that all verification documentation, including the Utility Performance Verification Report, Deviation Log, and Corrective Action Log, is archived for future audits and inspections.
3. Periodic verification of utility systems should be scheduled, based on the specific process change or as required by regulatory authorities, to ensure continued compliance with operational standards.
