In the RBI process, what are the two primary factors used to determine risk?

• A. Consequence of Failure and Service Class
• B. Reliability and the On-stream percentage
• C. Probability and Consequence of Failure
• D. Inspection Effectiveness and Corrosion Mechanism

Answer: (C)

In the Risk-Based Inspection (RBI) process, the two primary factors that are used to determine risk are the Probability of Failure and the Consequence of Failure. This approach allows organizations to prioritize their inspection and maintenance activities based on the risk that a failure poses to safety, the environment, and the integrity of the facility. The Probability of Failure focuses on the likelihood that a specific component or system will experience a failure within a defined timeframe. This assessment takes into account historical failure data, material conditions, and operating environments, which aids in quantifying how likely it is that a failure will occur. The Consequence of Failure considers the potential outcomes that would arise from a failure event. This encompasses various aspects, such as safety risks to personnel, environmental impacts, and economic losses. By understanding the potential severity of consequences, organizations can better prepare and respond to potential failure scenarios. When combined, these two factors provide a comprehensive view of the overall risk associated with a particular pressure vessel or system, enabling a more informed and efficient approach to inspection planning and resource allocation.
