NEW QUESTION # 11
In preparing for a future inspection, which of the following assessments can be used to determine what flaws would require repair or replacement?
- A. RBI
- B. COF
- C. POF
- D. FFS
Answer: D
Explanation:
Per Section 13.3 of API 580:
"A Fitness-For-Service (FFS) assessment (e.g., API 579-1/ASME FFS-1) may be performed to determine what size flaws, if found in future inspections, would require repair or equipment replacement." This makes Fitness-For-Service the correct method for evaluating whether existing or predicted flaws are tolerable or require corrective action.

NEW QUESTION # 12
________________may result in the calculated corrosion rate appearingartificially high or low.
- A. Measurement error
- B. Inspector error
- C. Ut scanning
- D. Clerical error
Answer: A
NEW QUESTION # 13
Hazard identification in a rbi analysis generally focuses on identifiable failure mechanisms in the equipment (inspectable causes) but does not explicitly deal with
- A. Other potential failure resulting from events such as flammable fire due to leak from equipment
- B. Environmental impact caused due to toxic release
- C. Other potential failure scenarios resulting from events such as power S failures or human errors
Answer: C
NEW QUESTION # 14
The governing inspection codes (such as API 510 and API 570) and jurisdictional regulations, if any, shall be reviewed to determine what?
- A. When the next turnaround must be scheduled
- B. When equipment that is deteriorating must be replaced
- C. If the risk of continued operation is acceptable
- D. A default maximum time periods for RBI reassessments
Answer: D
Explanation:
API 580 Section 14.3.2 clearly states:
"Users should set default maximum time periods for reassessments. The governing inspection codes (such as API 510, API 570, and API 653) and jurisdictional regulations, if any, shall be reviewed in this context." This means the codes and regulations are explicitly consulted to determine maximum allowable intervals between RBI reassessments. This ensures compliance with inspection frequency expectations across different jurisdictions and standards.

NEW QUESTION # 18

Answer: A
NEW QUESTION # 19
The risk prior to mitigation activities
- A. Mitigated risk
- B. Unmitigated risk
- C. Known risk
Answer: B
NEW QUESTION # 20
Inspection and decommissioning are forms of:
- A. risk mitigation.
- B. consequence mitigation.
- C. probability mitigation.
- D. risk analysis.
Answer: A
Explanation:
As stated in Section 13.1 of API 580:
"Inspection is often an effective method of risk management. However, inspection may not always provide sufficient risk mitigation or may not be the most cost-effective method." This clarifies that inspection is categorized under risk mitigation activities. Similarly, decommissioning is used as a risk mitigation strategy when the risk from continued operation becomes unacceptable.
Risk mitigation activities described in API 580 may:
reduce the magnitude of consequence,
reduce the probability of failure,
enhance survivability, or
mitigate the source of the consequence.
Thus, both inspection and decommissioning clearly fall under the broad category of risk mitigation.

NEW QUESTION # 21
___________ is usually not the primary objective of a RBI assessment, but it is frequently a side effect of
optimization.
- A. Increasing inspection costs
- B. Reducing inspection costs
- C. Increasing frequency of inspection programs
Answer: B
NEW QUESTION # 22
In RBI program discrimination between equipment items on the basis of significance of potential failures.
- A. A&B
- B. Determining failure modes
- C. Failure analysis
- D. Consequence analysis
Answer: A
NEW QUESTION # 23
_________ are the primary inputs into the probability of failure evaluation.
- A. Loss of containment f fluid
- B. Damage mechanisms and its severity
- C. Fluid toxicity and its concentration
- D. The deterioration mechanisms, rates and susceptibilities
Answer: D
NEW QUESTION # 24
Clearly documenting the key assumptions made during an RBI assessment will:
- A. allow recreation at a later date.
- B. quantify the level of acceptable risk.
- C. demonstrate the precision of the assessment.
- D. identify the level of residual risk.
Answer: A
Explanation:
According to Section 16.6 of API 580:
"Clearly documenting the key assumptions made during the analysis of probability and consequence will greatly enhance the capability to either recreate or update the RBI assessment." This confirms that the purpose of documenting assumptions is to ensure that future assessments can be reconstructed with accuracy and accountability. None of the other answer choices reflect this core reason.

NEW QUESTION # 25
Consequence is always.............For safety aspects
- A. Negative
- B. Neutral
- C. Positive
Answer: A
NEW QUESTION # 26
Which of the following constitutes a failure of equipment?
- A. Fire or explosion
- B. Corrosion beyond the corrosion allowance
- C. End of service life and time to replace
- D. Loss of containment
Answer: D
Explanation:
As per API 580, failure is typically defined in terms of a breach in the pressure boundary - most clearly indicated by loss of containment. In Section 5.2, API 580 explains the fundamental focus of RBI:
"One objective of RBI is to determine what incident could occur (consequence) in the event of an equipment failure and how likely (probability) it is that the incident could happen. For example, if a pressure vessel subject to damage from corrosion under insulation develops a leak, a variety of consequences could occur." This leak constitutes a loss of containment and is therefore categorized as a failure.
Other options are not necessarily defined as equipment failures:
B (corrosion beyond allowance) is degradation, but failure only occurs if it breaches containment.
C (end of service life) is a lifecycle condition, not a failure by definition.
D (fire or explosion) are consequences of a failure, not the failure itself.

NEW QUESTION # 27
The amount and type of codes and standards used by a facility can have
- A. No impact on RBI results
- B. Significant impact on RBI results
- C. Less significant impact on RBI results
Answer: B
NEW QUESTION # 28
Before decisions are made based on risk analysis results, what should be done first?
- A. The inspection plan should be completed
- B. A sensitivity analysis should be completed
- C. The inspector shall approve the results
- D. The risk analysis should be validated
Answer: D
Explanation:
API 580 Section 4.4 states:
"Therefore, the risk analysis should be validated before decisions are made based on the analysis results." Validation ensures that the risk analysis is accurate and reliable for decision-making. While sensitivity analysis is valuable (Option C), it does not substitute the need for validating the overall analysis.
Reference: API 580, 2nd Edition (2016), Section 4.4
