Which statement best describes the PCQI's role in validating preventive controls?

• A. The PCQI is not involved in validation.
• B. Validation is optional for certain products.
• C. Validation is conducted by external auditors only.
• D. The PCQI conducts validation of preventive controls, including justification for a timeframe beyond 90 days or a determination that validation is not required.

Answer: (D)

Validation of preventive controls is the PCQI’s responsibility. The PCQI must demonstrate that each preventive control can effectively prevent or reduce identified hazards to an acceptable level and document this evidence in a validation record. Part of this responsibility is deciding the validation timeline: most validations occur within a 90-day window, but the PCQI can justify extending beyond 90 days if needed, or determine that validation is not required for a particular control. This approach ensures there is a documented, science-based basis for how the controls work in practice and how often they need to be reassessed. External auditors do not perform all validation tasks, and validation is not optional for certain products—the PCQI leads this critical process.
