CMRT Corrective Maintenance 3 — Questions and Answers
Question 1: Which work order priority level typically signals an immediate safety or production-critical hazard requiring the fastest response?
- Routine
- Planned
- Emergency (Correct answer)
- Scheduled
Correct answer: Emergency
Emergency priority work orders are reserved for failures posing immediate safety risks or causing total production stoppage, demanding immediate technician response.
Question 2: Which piece of information is LEAST relevant on a corrective maintenance work order?
- Time the failure was reported
- Parts consumed during repair
- Technician's personal home address (Correct answer)
- Description of the failure symptoms
Correct answer: Technician's personal home address
A work order captures failure data, resource usage, and actions taken; personal information about the technician beyond an employee ID is not relevant.
Question 3: When multiple corrective work orders compete for limited technician resources, the BEST triage criterion is:
- Alphabetical order of equipment name
- Safety risk and production impact (Correct answer)
- Technician's personal familiarity with the equipment
- Equipment purchase date
Correct answer: Safety risk and production impact
Prioritizing by safety risk and production impact ensures that the most critical failures are addressed first, protecting personnel and minimizing revenue loss.
Question 4: Backlog management in a corrective maintenance program primarily involves:
- Tracking completed preventive maintenance tasks
- Reviewing spare parts inventory levels
- Managing and prioritizing the list of pending maintenance work orders (Correct answer)
- Scheduling employee vacation time
Correct answer: Managing and prioritizing the list of pending maintenance work orders
Backlog management ensures pending corrective work orders are ranked, resourced, and executed in order of priority before the backlog grows unmanageable.
Question 5: A corrective maintenance work order is typically initiated when:
- A preventive maintenance inspection is due
- A new piece of equipment is purchased
- Equipment fails or its performance drops below acceptable standards (Correct answer)
- The maintenance manager requests a quarterly budget review
Correct answer: Equipment fails or its performance drops below acceptable standards
Corrective maintenance is triggered by an actual failure event or a detected degradation that renders the equipment unable to meet its required function.
Question 6: The PRIMARY purpose of documenting corrective maintenance activities in a CMMS is to:
- Justify overtime pay for technicians
- Build a failure history that supports root cause analysis and future planning (Correct answer)
- Satisfy accounting department requirements only
- Prove that technicians were present on site
Correct answer: Build a failure history that supports root cause analysis and future planning
Accurate failure records create a data-driven history that enables trend analysis, root cause investigations, and informed decisions about PM intervals and spare parts.
Question 7: Which metric BEST indicates the average time a corrective maintenance team takes to restore equipment to operational status?
- Mean Time Between Failures (MTBF)
- Overall Equipment Effectiveness (OEE)
- Planned Maintenance Percentage (PMP)
- Mean Time to Repair (MTTR) (Correct answer)
Correct answer: Mean Time to Repair (MTTR)
MTTR (Mean Time to Repair) specifically measures the average elapsed time from failure detection to equipment restoration, making it the key corrective maintenance efficiency metric.
