Objective
The objective of this Design Qualification (DQ) protocol is to ensure that the Nitrogen Purging System used for prefilled syringes and cartridges meets the specified requirements and performs as intended to provide an inert atmosphere, thereby maintaining product integrity.
Scope
This DQ protocol applies to the Nitrogen Purging System located in the Production area, specifically used for prefilled syringes and cartridges. The protocol encompasses the validation of the system’s critical parameters and compliance with URS Annex11 standards.
Responsibilities
The following personnel are responsible for the execution of this protocol:
- Validation Team: Responsible for conducting the DQ activities.
- Quality Assurance: Ensures compliance with regulatory standards and protocols.
- Production Manager: Oversees the operation of the Nitrogen Purging System.
Prerequisites
Prior to executing this DQ protocol, the following must be completed:
- Installation Qualification (IQ) must be completed and approved.
- Operational Qualification (OQ) must be completed and approved.
- All personnel involved must be trained on the operation of the Nitrogen Purging System.
Equipment Description
The Nitrogen Purging System is designed to provide an inert atmosphere during the production of prefilled syringes and cartridges. It operates by purging the production environment with high-purity nitrogen, preventing oxidation and contamination.
Test Plan
| Test ID | Procedure | Acceptance | Evidence |
|---|---|---|---|
| DQ-01 | Verify nitrogen purity levels using gas analyzer. | Nitrogen purity ≥ 99.99% | Gas analyzer log report |
| DQ-02 | Review flow audit trail logs for consistency. | Logs show continuous flow during operation | Audit trail report |
Detailed Test Cases
Test Case DQ-01: Nitrogen Purity Verification
Procedure: Utilize a calibrated gas analyzer to measure nitrogen purity. Record the purity percentage and ensure it meets the acceptance criteria.
Expected Result: Nitrogen purity is confirmed to be ≥ 99.99%.
Test Case DQ-02: Flow Audit Trail Review
Procedure: Access the system’s audit trail logs to verify that nitrogen flow is consistent and uninterrupted during operation.
Expected Result: Audit trail logs indicate continuous nitrogen flow throughout the production cycle.
Deviations
Any deviations from the acceptance criteria must be documented and assessed for impact on product quality. Corrective actions should be implemented as necessary.
Approvals
This Design Qualification Protocol requires approval from the following individuals:
- Validation Manager: ____________________ Date: ___________
- Quality Assurance Manager: ____________________ Date: ___________
- Production Manager: ____________________ Date: ___________
Data Integrity Checks
As CSV is required, the following data integrity checks will be implemented:
- Automated data capture for nitrogen purity and flow parameters to ensure accurate record-keeping.
- Regular backups of audit trail logs to prevent data loss.
- Access controls to restrict unauthorized changes to critical data.
