1. Purpose
To define the procedure for managing in-process gel rejections during the manufacturing process, including detection, segregation, documentation, investigation, and disposition in accordance with GMP and quality assurance protocols.
2. Scope
This SOP applies to all in-process gel product batches that show deviation from specifications during any stage of the gel manufacturing process at the facility.
3. Responsibilities
- Production Operator: Identifies and segregates non-conforming gel product during processing.
- Production Supervisor: Reviews rejection, initiates deviation or rejection report, and informs QA.
- Quality Assurance:
Investigates rejection cause, approves segregation, and monitors corrective action.
4. Accountability
The Head – Manufacturing is accountable for ensuring adherence to this SOP and taking necessary actions to prevent recurrence of rejections.
5. Procedure
5.1 Identification and Segregation
- Immediately identify and report non-conforming gel material such as discolored gel, presence of foreign matter, abnormal odor, incorrect pH, etc.
- Physically segregate the affected material and label with “Rejected – Under Investigation”.
- Record batch details, quantity, rejection type, and location of segregation in the In-Process Rejection Log – Annexure-1.
5.2 Investigation and Documentation
- Production Supervisor initiates an internal deviation report or rejection form.
- QA investigates root cause, evaluates impact on product quality, and determines disposition.
- Document all findings in the Rejection Investigation Report – Annexure-2.
5.3 Disposition of Rejected Material
- If the rejection is due to correctable issues (e.g., pH adjustment), reprocessing may be considered upon QA approval.
- If the rejection is due to contamination or irreversible degradation, dispose of the material as per SOP on Waste Disposal.
- QA must authorize and document the destruction of rejected material using Destruction Record – Annexure-3.
5.4 Corrective and Preventive Action
- Root cause trends to be analyzed quarterly by QA for recurring rejection reasons.
- CAPA to be initiated where applicable and tracked through the QA CAPA system.
5.5 Line Clearance and Process Continuation
- After segregation and corrective measures, the manufacturing area must be cleared by QA before resumption.
- Ensure all records are updated and traceable for audit readiness.
6. Abbreviations
- CAPA: Corrective and Preventive Action
- QA: Quality Assurance
- GMP: Good Manufacturing Practices
