How often should a safety inspection occur after a major availability?

The correct frequency for safety inspections after a major availability is every three years. This timeline is aligned with standard practices in safety management to ensure that equipment and systems are regularly evaluated and maintained to meet safety standards.

Conducting thorough inspections every three years allows for a comprehensive review of equipment, ensuring any potential hazards or wear and tear can be addressed before they pose a risk. This interval strikes a balance between being frequent enough to catch issues while also being practical and manageable within operational constraints.

In contrast, options suggesting a monthly or daily inspection may not be feasible or necessary for every facet of equipment or safety measures following a major availability, as such frequent inspections could lead to resource strain and unnecessary operational downtime. An annual inspection, while more frequent than three years, may still not catch issues that can develop in that timeframe, potentially resulting in safety oversights. Thus, every three years is considered an effective period for comprehensive safety assessments to safeguard personnel and operations.
