1. Purpose
To lay down a standard procedure for the qualification of transfer lines and hoses used for transferring raw materials and finished gel products, ensuring material compatibility, cleanliness, and integrity during production processes.
2. Scope
This procedure is applicable to all new and existing transfer lines and hoses used in the gel manufacturing process at the facility, including temporary and permanent connections between tanks, vessels, and filling lines.
3. Responsibilities
- Engineering Department: Responsible for installation and mechanical integrity checks.
- Production Chemist: Initiates
and monitors qualification protocol execution.
Quality Assurance: Reviews qualification data and approves results before line usage.
4. Accountability
Head – Manufacturing is accountable for ensuring that all transfer lines and hoses are qualified and maintained according to regulatory and in-house quality standards.
5. Procedure
5.1 Initiation
- Identify new transfer lines or hoses requiring qualification.
- Assign a unique Equipment ID and label the item.
- Prepare and approve a qualification protocol including IQ, OQ, and PQ elements.
5.2 Installation Qualification (IQ)
- Verify construction material compatibility with the gel formulation (e.g., silicone, PTFE).
- Inspect physical condition, connectors, and clamps for mechanical integrity.
- Check for cleanability and drainability features.
5.3 Operational Qualification (OQ)
- Perform pressure leak test at defined operational pressure using purified water or inert gas.
- Check flow rate under simulated manufacturing conditions.
- Ensure connectors function properly with no visible leakage or misalignment.
5.4 Performance Qualification (PQ)
- Run media trials (e.g., gel placebo) through the transfer line under normal operating conditions.
- Assess hold-up volume, dead leg presence, and cleaning efficiency post-use.
- Conduct microbial swab testing after cleaning to verify cleanliness.
5.5 Documentation and Approval
- Compile IQ/OQ/PQ reports and attach test data, results, and deviations (if any).
- QA to review and approve the qualification summary report.
- Enter qualification details into the Equipment Qualification Register.
5.6 Requalification
- Perform requalification every 3 years or earlier in case of damage or design change.
- Document requalification in the same format with revision tracking.
