What is the primary objective of corrective maintenance?
Answer: To restore equipment to a functional state after a failure has occurred.
Corrective maintenance is a reactive strategy focused on repairing and restoring equipment to operational condition after a fault or breakdown has already happened.
Which of the following scenarios best illustrates deferred corrective maintenance?
Answer: An operator reports a minor, non-critical guard is loose. Maintenance schedules the repair for the next planned downtime.
Deferred corrective maintenance involves a known issue that does not pose an immediate risk, allowing the repair to be planned and scheduled for a more convenient time to minimize disruption.
An operator reports that a pneumatic conveyor system has completely stopped. After performing a lockout/tagout procedure, what is the MOST logical first step a maintenance technician should take to troubleshoot the problem?
Answer: Verify the availability and proper pressure of the main compressed air supply.
Effective troubleshooting begins by checking the most fundamental inputs to the system. For a pneumatic system, the primary energy source is compressed air. Verifying its availability and pressure is the quickest way to rule out a simple, system-wide cause before investigating more complex component failures.
After completing a corrective maintenance task on a recurring equipment failure, what is the most important follow-up activity to prevent future occurrences?
Answer: Performing a Root Cause Analysis (RCA).
Simply fixing the symptom does not address the underlying problem. Performing an RCA is crucial for identifying the fundamental reason for the failure, which allows for a permanent solution to be implemented to prevent it from happening again.
A technician responds to a catastrophic bearing failure on a main plant air compressor that has shut down all production. This type of maintenance activity is best classified as:
Answer: Emergency Corrective Maintenance
This scenario describes an unplanned, sudden failure of a critical asset that has a severe impact on operations, requiring immediate attention. This is the definition of emergency corrective maintenance.
A technician successfully repairs a hydraulic leak on a press by replacing a failed hose. Before closing the work order, which piece of information is MOST valuable to record for future reliability analysis?
Answer: The specific cause of the hose failure (e.g., abrasion, age, over-pressurization).
Recording the specific cause of failure (the failure mode) is critical data for reliability analysis and Root Cause Analysis. If a pattern emerges, such as many hoses failing due to abrasion, engineers can implement a proactive solution like re-routing hoses or adding protective sleeves to prevent future failures.
