Maintenance & Repair Procedures Flashcards

A facility manager uses vibration analysis on pumps to schedule bearing replacement before failure. What maintenance strategy is this?

Answer: Predictive maintenance

Predictive maintenance uses condition-monitoring data such as vibration readings to schedule work just before failure is likely.

What is the main purpose of a Computerized Maintenance Management System (CMMS)?

Answer: Tracking work orders, asset histories, and preventive maintenance schedules

A CMMS holds asset records, creates and tracks work orders, and automates PM scheduling.

An owner lets non-critical light fixtures operate until they fail, then replaces them. This is best described as:

Answer: Run-to-failure (corrective) maintenance

Run-to-failure is a deliberate corrective strategy for low-cost, non-critical items where failure has little consequence.

Which term describes maintenance and repairs that were needed but postponed because of budget limits?

Answer: Deferred maintenance

Deferred maintenance is work that was put off, and it builds up into a backlog of growing liability.

Before servicing a machine that could unexpectedly energize, workers must follow which OSHA standard?

Answer: 29 CFR 1910.147 Control of Hazardous Energy (Lockout/Tagout)

OSHA 1910.147 requires energy-control procedures so that equipment is isolated and locked out before servicing.

A maintenance metric that measures the average operating time between failures of repairable equipment is:

Answer: MTBF

Mean Time Between Failures (MTBF) measures reliability as the average run time between breakdowns.

When are operation and maintenance (O&M) manuals normally turned over to the owner on a construction project?

Answer: During project closeout before final payment

O&M manuals, warranties, and as-builts are closeout deliverables that are usually required before final payment.
