API 580 Risk Based Inspection Practice Test

Which internal factor can increase inspection risks?

1. Proper maintenance schedules

2. Moisture ingress

3. Use of high-quality materials

4. Consistent operational procedures

The correct answer is: Moisture ingress

Moisture ingress is a significant internal factor that can increase inspection risks because it can lead to various forms of degradation in equipment and piping systems. When moisture penetrates the internal environment of machinery or storage tanks, it can promote corrosion, particularly in metal components. This degradation can weaken structural integrity, create cracks, and eventually lead to failures or leaks, which can pose safety hazards and environmental concerns. Understanding the impact of moisture ingress is critical in risk-based inspection programs. It necessitates that inspection intervals be adjusted to account for the potential accelerated degradation of materials due to moisture exposure. Consequently, recognizing moisture ingress as a risk factor allows organizations to implement more frequent inspections or additional preventive measures to mitigate the associated risks. In contrast, the other options listed – proper maintenance schedules, use of high-quality materials, and consistent operational procedures – are all external and proactive factors contributing to lower inspection risks. These practices typically enhance the reliability and longevity of equipment, thereby reducing the overall risk profile associated with inspections.
