Operational Qualification Protocol for Cryo/Cold Storage Equipment
Objective: To validate the operational performance of Cryo/Cold Storage equipment used for storing NDDS intermediates, drug substances (DS), and drug products (DP) under controlled temperature conditions.
Scope: This protocol applies to the Cryo/Cold Storage equipment located in the Warehouse/QA area, which is critical for maintaining the integrity of NDDS products.
Responsibilities:
- Validation Team: Prepare and execute the OQ protocol.
- Quality Assurance (QA): Review and approve the protocol and results.
- Warehouse Personnel: Ensure compliance with storage procedures.
Prerequisites:
- Installation Qualification (IQ) completed.
- Equipment calibrated and maintained as per SOP.
- Personnel trained in equipment operation and monitoring.
Equipment Description:
The Cryo/Cold Storage unit operates within the temperature range of 2–8°C, -20°C, and -80°C. It is equipped with temperature mapping, alarms, and an audit trail system to ensure compliance with regulatory requirements.
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| OQ-01 | Temperature mapping of storage areas. | Temperature remains within specified limits. | Mapping report with temperature logs. |
| OQ-02 | Alarm functionality test. | Alarms activate at set thresholds. | Alarm test log. |
| OQ-03 | Audit trail verification. | Complete and accurate audit trail maintained. | Audit trail report. |
Detailed Test Cases:
- OQ-01: Conduct temperature mapping using calibrated sensors. Place sensors in critical locations and log data over 24 hours. Verify that all readings fall within the specified limits of 2–8°C, -20°C, and -80°C.
- OQ-02: Simulate temperature excursions to test alarm functionality. Verify that alarms trigger at defined thresholds and that notifications are logged appropriately.
- OQ-03: Review the audit trail for completeness. Ensure all entries are time-stamped and that there are no gaps in data logging.
Deviations: Any deviations from the acceptance criteria must be documented and investigated. A corrective action plan should be developed and implemented as necessary.
