Which type of maintenance work order should receive the highest scheduling priority in a facilities maintenance program?
Answer: Safety-related and emergency corrective work
Safety-related and emergency corrective work must be prioritized above all other maintenance activities to protect personnel, assets, and regulatory compliance.
What does the term 'maintainability' refer to in reliability engineering?
Answer: The ease and speed with which a system can be restored to operating condition after a failure
Maintainability is the probability that a failed system can be restored to an operational state within a given time under specified conditions, often quantified by MTTR.
In a computerized maintenance management system (CMMS), the primary purpose of an asset hierarchy is to:
Answer: Organize assets by location and system for efficient planning and reporting
An asset hierarchy in a CMMS organizes equipment by site, building, system, and component, enabling efficient work order routing, cost roll-up, and performance reporting.
Which lubrication practice best reduces the risk of cross-contamination between incompatible greases?
Answer: Color-coding grease guns and fittings by lubricant type
Color-coding grease guns and fittings by lubricant type is an industry best practice that prevents technicians from accidentally mixing incompatible greases.
The 'bathtub curve' in reliability engineering describes:
Answer: The failure rate pattern showing infant mortality, useful life, and wear-out phases
The bathtub curve illustrates three failure rate phases: high early (infant mortality), low and constant (useful life), and increasing (wear-out), guiding maintenance strategy selection.
What is the purpose of a backlog in a maintenance management program?
Answer: To serve as a managed queue of approved work awaiting scheduling and resources
A maintenance backlog is an organized list of approved, pending work orders that have not yet been scheduled, helping planners match work to available labor and materials.
Vibration analysis is most effective for detecting which type of mechanical problem in rotating equipment?
Answer: Imbalance, misalignment, and bearing wear
Vibration analysis excels at detecting mechanical issues in rotating machinery such as rotor imbalance, shaft misalignment, looseness, and bearing degradation.
