During periodic inspections, if results deviate by more than 10% from past documentation, what should be done?

• A. Immediately discuss the deviation with the manufacturer
• B. Ignore the deviation
• C. Re-test after 24 hours
• D. Retain results without action

Answer: (A)

Significant deviations from past documentation during periodic inspections signal a potential drift or fault in the equipment. When the difference exceeds the 10% tolerance, the responsible technician should immediately notify and consult the equipment manufacturer for guidance on next steps, which may include recalibration, service, or replacement as appropriate. This ensures the results are interpreted correctly and the system remains safe and compliant. Ignoring the deviation or simply re-testing later without manufacturer input risks unsafe operation and noncompliance, and retaining results without action provides no remedy.
