Which option correctly lists the intervals for welder qualifications (months), above-grade visual surveillance (months), and visual examiner eye check (months), respectively?

• A. 6, 12, 12
• B. 12, 6, 12
• C. 6, 6, 12
• D. 6, 6, 6

Answer: (C)

Periodic renewal of qualifications and health checks is used to keep performance up to date in safety-critical tasks like welding, elevated inspections, and visual exams. Welder qualifications drift if not refreshed, so a six-month interval helps ensure welders stay current with procedures, techniques, and code requirements. Above-grade visual surveillance must also be kept fresh regularly because conditions on elevated piping can change with service, corrosion, coatings, or damage, and catching issues early typically relies on a consistent inspection cadence. The visual examiner’s eye health is crucial for accurate inspections, but vision tends to remain reliable over a longer span, making an annual eye check appropriate to ensure the examiner can still perform precision visual work. Therefore, the combination of six months for welder qualifications, six months for above-grade visual surveillance, and twelve months for the visual examiner’s eye check best aligns with maintaining essential skills and reliability while balancing practicality and safety.
