Document Control:
Document Number: DQ-001
Version: 1.0
Effective Date: [Insert Date]
Review Date: [Insert Date]
Objective
This Design Qualification (DQ) protocol aims to ensure that the Cryo/Cold Storage equipment used for storing NDDS intermediates, drug substances (DS), and drug products (DP) meets the specified requirements and is validated for intended use.
Scope
This protocol applies to the Cryo/Cold Storage equipment located in the Warehouse/QA area, specifically designated for the storage of NDDS intermediates, DS, and DP.
Responsibilities
The following personnel are responsible for the execution and approval of this protocol:
- Validation Team: Execute and document the DQ protocol.
- Quality Assurance: Review and approve the DQ protocol.
- Warehouse Manager: Ensure equipment is maintained and operational.
Prerequisites
Prior to executing this protocol, the following must be completed:
- Installation Qualification (IQ) of the Cryo/Cold Storage equipment.
- Operational Qualification (OQ) of the Cryo/Cold Storage equipment.
- Training of personnel on equipment operation and monitoring.
Equipment Description
The Cryo/Cold Storage equipment is designed to maintain temperatures between 2–8°C, -20°C, and -80°C for the storage of NDDS intermediates, DS, and DP. Key features include:
- Temperature mapping capabilities.
- Alarm systems for temperature deviations.
- Audit trails for monitoring and compliance.
Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| T1 | Temperature mapping of storage areas. | Temperature remains within specified limits (2–8°C, -20°C, -80°C). | Temperature mapping report. |
| T2 | Alarm system functionality check. | All alarms function correctly and trigger at specified limits. | Alarm test report. |
| T3 | Audit trail verification. | Audit trails are complete and accurate for the last 6 months. | Audit trail report. |
Detailed Test Cases
Test Case T1: Temperature Mapping
Procedure: Conduct temperature mapping using calibrated data loggers placed at various locations within the storage unit. Record temperature data over a 24-hour period.
Acceptance Criteria: All recorded temperatures must remain within the specified limits.
Evidence: Submit temperature mapping report with data logger readings.
Test Case T2: Alarm System Test
Procedure: Simulate temperature excursions to test alarm functionality. Document alarm response time and accuracy.
Acceptance Criteria: Alarms must activate within 5 minutes of temperature deviation.
Evidence: Alarm test report with response times.
Test Case T3: Audit Trail Verification
Procedure: Review the audit trail for completeness and accuracy, ensuring all entries are time-stamped and user-identified.
Acceptance Criteria: No gaps or inaccuracies in the audit trail.
Evidence: Audit trail report for the last 6 months.
Deviations
Any deviations from the acceptance criteria must be documented and investigated. A corrective action plan should be developed and implemented where necessary.
