WFI Storage Tank – Equipment Validation SOP

Equipment Validation Procedure for WFI Storage Tank

Purpose: This SOP provides guidelines for the validation of the WFI Storage Tank to ensure it meets regulatory and operational requirements.

Scope: This procedure applies to the validation of the WFI Storage Tank used in the Utilities area for storing Water for Injection (WFI) in pharmaceutical operations.

Definitions:

  • WFI: Water for Injection, a critical component in pharmaceutical manufacturing.
  • Validation: The process of ensuring that a system meets its intended use and compliance requirements.
  • DQ: Design Qualification.
  • IQ: Installation Qualification.
  • OQ: Operational Qualification.
  • PQ: Performance Qualification.

Roles:

  • Validation Team: Responsible for the execution and documentation of the validation process.
  • Quality Assurance: Ensures compliance with regulatory requirements and approval of validation documentation.
  • Maintenance Team: Responsible for the ongoing maintenance and calibration of the WFI Storage Tank.

Lifecycle Procedure:

  1. Conduct Design Qualification (DQ) to ensure the WFI Storage Tank meets user requirements.
  2. Perform Installation Qualification (IQ) to verify that the equipment is installed according to specifications.
  3. Execute Operational Qualification (OQ) to confirm that the equipment operates within defined parameters.
  4. Carry out Performance Qualification (PQ) to validate the equipment’s performance under actual operating conditions.

GDP Controls: Good Documentation Practices must be adhered to throughout the validation process, ensuring all records are complete, accurate, and legible.

Acceptance Criteria Governance: Acceptance criteria will be established based on User Requirement Specifications (URS) and Annex 15 guidelines to ensure compliance and quality.
