🔴 1. Inspection shows no defects, but corrosion rate is high
What is the BEST action?
- Reduce inspection
B. Ignore corrosion data
C. Maintain or increase inspection
D. Assume no risk
👉 Answer: C
➡️ No defects ≠ no risk. Corrosion trend drives PoF.
🔴 2. Low PoF but extremely high CoF
Risk level?
- Low
B. Medium
C. High
D. Zero
👉 Answer: C
➡️ High consequence dominates risk.
🔴 3. Vendor confirms equipment is safe without documentation
Best action?
- Accept vendor statement
B. Reduce inspection
C. Verify with data/documents
D. Ignore
👉 Answer: C
➡️ Never rely on vendor alone.
🔴 4. Inspection interval reduced without RBI review
What should be done?
- Accept
B. Ignore
C. Reassess RBI
D. Reduce risk
👉 Answer: C
🔴 5. New operating condition increases pressure
Best action?
- Ignore
B. Reassess risk
C. Reduce inspection
D. Accept
👉 Answer: B
🔴 6. Inspection effectiveness is low
Impact on risk?
- Decreases risk
B. No change
C. Increases risk
D. Eliminates risk
👉 Answer: C
➡️ Poor detection = higher uncertainty → higher PoF.
🔴 7. Equipment has never failed before
Risk level?
- Zero
B. Low
C. Depends on conditions
D. Ignore
👉 Answer: C
🔴 8. Conflicting inspection results from two methods
Best action?
A.Choose cheaper method
B. Average results
C. Investigate discrepancy
D. Ignore
👉 Answer: C
🔴 9. Repair completed but RBI not updated
What is correct?
A. Risk unchanged
B. Risk reduced automatically
C. Update RBI model
D. Ignore
👉 Answer: C
🔴 10. High consequence equipment in good condition
Inspection strategy?
A. Reduce inspection
B. Ignore
C. Maintain priority
D. Remove from RBI
👉 Answer: C
🔴 11. Poor data quality in RBI study
Best approach?
A. Proceed normally
B. Reduce risk
C. Increase uncertainty and improve data
D. Ignore
👉 Answer: C
🔴 12. Corrosion rate suddenly increases
What should be done?
A. Ignore
B. Update PoF and reassess risk
C. Reduce inspection
D. Accept
👉 Answer: B
🔴 13. Multiple damage mechanisms present
How to assess risk?
A. Use lowest risk
B. Combine effects
C. Ignore minor ones
D. Average them
👉 Answer: B
🔴 14. Inspection shows safe condition but RBI shows high risk
Best action?
A. Trust inspection only
B. Ignore RBI
C. Reassess model and data
D. Reduce inspection
👉 Answer: C
🔴 15. Equipment moved to populated area
Impact?
A. No change
B. Lower risk
C. Increase consequence
D. Reduce inspection
👉 Answer: C
🔴 16. Safety-critical system failure possibility
Risk approach?
A. Ignore
B. Focus on cost
C. Prioritize due to consequence
D. Reduce inspection
👉 Answer: C
🔴 17. Inspection overdue
Best action?
A. Ignore
B. Assume safe
C. Reassess risk
D. Reduce inspection
👉 Answer: C
🔴 18. RBI model based on outdated data
What to do?
A. Use anyway
B. Ignore
C. Update model
D. Reduce risk
👉 Answer: C
🔴 19. High cost but low consequence failure
Priority?
A. High
B. Medium
C. Low
D. Critical
👉 Answer: C
➡️ Cost ≠ risk driver (CoF matters more).
🔴 20. You are unsure between two answers
Best exam strategy?
- Choose faster option
B. Choose cheaper option
C. Choose safer, data-driven action
D. Random
👉 Answer: C
🧠 WHY THESE QUESTIONS ARE “TRICKY”
They test whether you:
✔ Trust data over assumptions
✔ Understand PoF vs CoF
✔ Know RBI is dynamic
✔ Prioritize consequence
✔ Avoid “inspection = safety” thinking
🔥 FINAL EXAM HACK
When stuck, choose the answer that:
✔ Reassesses risk
✔ Uses full data
✔ Escalates uncertainty
✔ Protects safety
