Question 1 of 131

RBI may include methodologies to assess the effectiveness of the management systems in maintaining

Mechanical integrity

Total asset integrity

Plant integrity

Correct Answer: B

The term 'total asset integrity' encompasses a broader scope, ensuring that all aspects of an organization's assets, including mechanical, structural, and process integrity, are maintained effectively. RBI (Risk-Based Inspection) methodologies are typically aligned with ensuring the overall integrity of assets rather than focusing solely on mechanical aspects or limiting it to a specific part like the plant.

Question 2 of 131

Equipment reliability is especially important if leaks can be caused by

Secondary failures, such as loss of utilities

Primary failures such as leak due to severe corrosion

Tertiary failures due to valve gland packing leak

Correct Answer: A

Equipment reliability is especially important if leaks can be caused by secondary failures, such as loss of utilities. In these scenarios, the failure of equipment can lead to cascading issues affecting overall system performance and safety. Ensuring reliability helps prevent such secondary failures and the potential leaks they might cause.

Question 3 of 131

Reliability efforts, such as reliability centered maintenance (REM), can be linked with RBI, resulting in an integrated program to

Reduce downtime in an operating unit

Reduce operating time of a unit

To reduce risk by mitigation activities

Correct Answer: C

Reliability centered maintenance (REM) and risk-based inspection (RBI) are both approaches aimed at improving the reliability and safety of equipment. The key objective of integrating these programs is to reduce risk through mitigation activities. By assessing potential risks and implementing maintenance strategies that address those risks, the overall reliability of the equipment is enhanced, and the likelihood of failures that could lead to downtimes or hazards is minimized.

Question 4 of 131

Loss of containment is

Loss of fluid to the external environment

Container loss at the port authority

Risk related to containers

B&C

Correct Answer: A

Loss of containment refers specifically to the unintended release of fluids (liquids or gases) from their containment systems, such as pipes or vessels, into the external environment. This definition is commonly used in industries dealing with chemicals, petrochemicals, and other hazardous materials to describe incidents where there is a failure in the containment system resulting in a leak or spill.

Question 5 of 131

______________ to be established to judge acceptability of risk could he an objective of the RBI assessment if such criteria do not exist already within the user's company.

Risk criteria

Risk plan

Risk analysis

Correct Answer: A

Risk criteria need to be established to judge the acceptability of risk. These criteria provide a benchmark against which the level of risk can be compared to determine if it is acceptable or requires further action. Therefore, the establishment of risk criteria is a logical objective of the RBI assessment if such criteria do not already exist within the user's company.
