Layer of Protection Analysis (LOPA) is primarily used to:
Answer: Verify that independent protection layers reduce risk to tolerable levels
LOPA evaluates whether the combined probability reduction of independent protection layers brings risk to within tolerable limits.
A reliability engineer notices that corrective maintenance time is dominated by 'waiting for parts.' This indicates a weakness in:
Answer: Spare parts management (logistics)
Long wait-for-parts time indicates a spare parts supply or inventory management problem, directly inflating MTTR.
When a fault tree is solved using Boolean algebra, which expression correctly represents an OR gate with inputs A and B?
Answer: A + B
In Boolean algebra, an OR gate is represented by addition (A + B), meaning the output occurs if either A or B occurs.
Which risk communication principle states that risk information should be presented consistently whether framing outcomes as gains or losses?
Answer: Framing neutrality
Framing neutrality requires presenting the same statistical risk both positively (survival rates) and negatively (mortality rates) to avoid biasing decisions.
A proactive maintenance program has reduced unplanned downtime by 40% but maintenance costs have doubled. The BEST next step is to:
Answer: Perform a maintenance value analysis to optimize the PM frequency
A maintenance value analysis (or optimization study) identifies tasks that are over-maintained and can be extended or eliminated to restore cost-effectiveness.
Which document formally defines the asset functions, performance standards, and failure modes as the foundation for an RCM analysis?
Answer: Failure Mode and Effects Record (Information Worksheet)
The RCM Information Worksheet captures each function, its performance standard, and associated failure modes as the structured input to the decision process.
In risk management, 'residual risk' is defined as the risk that remains after:
Answer: All risk mitigation and control measures have been applied
Residual risk is the level of risk remaining after all planned risk controls and mitigations have been implemented.
