Standard Operating Procedure for Equipment Validation of Explosion-Proof HVAC System

Purpose

This Standard Operating Procedure (SOP) outlines the validation process for the Explosion-Proof HVAC System utilized in the production of Transdermal Patches, ensuring environmental conditions are controlled safely and effectively.

Scope

This SOP applies to the validation of the Explosion-Proof HVAC System in the production area designated for Transdermal Patches. It covers the Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) phases.

Definitions

• DQ: Design Qualification
• IQ: Installation Qualification
• OQ: Operational Qualification
• PQ: Performance Qualification
• CSV: Computerized System Validation

Roles

• Validation Team: Responsible for executing the validation activities.
• Quality Assurance: Oversees compliance and approval of validation documentation.
• Maintenance Personnel: Conducts regular calibration and preventive maintenance.

Lifecycle Procedure

1. Conduct Design Qualification (DQ) to ensure system specifications meet operational requirements.
2. Perform Installation Qualification (IQ) to verify that the system is installed correctly and according to specifications.
3. Execute Operational Qualification (OQ) to confirm that the system operates within specified limits.
4. Complete Performance Qualification (PQ) to validate the system’s performance under actual production conditions.

Good Documentation Practices (GDP) Controls

All validation documentation must be completed in accordance with Good Documentation Practices, ensuring accuracy, legibility, and traceability throughout the validation process.

Acceptance Criteria Governance

Acceptance criteria will be based on the following:

• Temperature, Relative Humidity (RH), and pressure must be maintained within specified ranges.
• Audit trail logs must be reviewed and retained for compliance verification.

Calibration and Preventive Maintenance Governance

Calibration and preventive maintenance activities must be scheduled and documented according to the manufacturer’s recommendations and internal policies to ensure ongoing compliance and performance.

Change Control Triggers

Any changes to the HVAC system, including software updates, hardware modifications, or changes in operational procedures, must be assessed for validation impact and documented through the Change Control process.

Revalidation Triggers and Periodic Review

Revalidation is required under the following circumstances:

• Significant changes to the system or its environment.
• Failure to meet acceptance criteria during routine monitoring.
• Every three years as part of the periodic review process.
