NEW QUESTION # 54
Depending on factors such as the remaining life of the equipment and the type of damage mechanism, risk management through inspection:
- A. is the least cost-effective.
- B. is most effective in reducing risk.
- C. may have little or no effect.
- D. results in a decrease in inspection frequencies.
Answer: C
Explanation:
API 580, Section 12.4 states:
"Depending on factors such as the remaining life of the equipment and type of damage mechanism, risk management through inspection may have little or no effect." Examples include:
Instantaneous failures
Equipment at end of life
Damage mechanisms not detectable through inspection
Reference: API 580, 2nd Edition (2016), Section 12.4

NEW QUESTION # 55
An iso-risk line on a risk plot is a line:
- A. of same-risk consequence.
- B. of constant risk.
- C. of same-risk probability.
- D. showing direction of increasing risk.
Answer: B
Explanation:
Section 11.6.3 of API 580 defines iso-risk lines:
"An ISO-risk line represents a constant risk level... All items that fall on or very near the ISO-risk line are roughly equivalent in their level of risk." This confirms that iso-risk lines plot constant risk across varying combinations of probability and consequence.
Reference: API 580, 2nd Edition (2016), Section 11.6.3 - Risk Plots
NEW QUESTION # 56
RBI as a risk-based approach focuses attention specifically on:
- A. the equipment and associated damage mechanisms.
- B. on-stream inspections in lieu of internal inspections.
- C. consequence-based inspection intervals.
- D. inspection intervals based on a percentage of equipment life.
Answer: A
Explanation:
According to API 580, Section 4.3:
"RBI as a risk-based approach focuses attention specifically on the equipment and associated damage mechanisms representing the most risk to the facility." This confirms that the correct focus of RBI is on the equipment and the damage mechanisms that pose the greatest risk-making Option A correct. Other options are examples of traditional inspection strategies, not the defining focus of RBI.
Reference: API 580, 2nd Edition (2016), Section 4.3
