Question 1

A small, inexpensive bearing on a non-critical conveyor can be swapped out in minutes from stock, and its failure causes no safety risk and no loss of production. Which maintenance strategy is the MOST cost-effective choice for this component?

  1. Monthly time-based preventive replacement
  2. Continuous vibration-based condition monitoring
  3. Run-to-failure
  4. A full reliability-centered maintenance study
Show answer & explanation

Correct answer: C - Run-to-failure

Question 2

A plant performs an intrusive preventive maintenance task far more frequently than the equipment's failure history justifies. Beyond the obvious waste of labor and materials, what is the other MOST likely consequence?

  1. Failures of this kind are now guaranteed to be eliminated entirely
  2. New failures introduced during the unnecessary intrusive work
  3. An automatic increase in the asset's recorded replacement value
  4. Condition monitoring becoming mandatory under OSHA regulation
Show answer & explanation

Correct answer: B - New failures introduced during the unnecessary intrusive work

Question 3

A maintenance manager wants to detect a loose, overheating electrical connection inside an energized switchgear panel before it fails. Which predictive maintenance technology is BEST suited to this task?

  1. Vibration analysis
  2. Oil (lubricant) analysis
  3. Infrared thermography
  4. Ultrasonic leak detection
Show answer & explanation

Correct answer: C - Infrared thermography

Question 4

A critical pump has a Mean Time Between Failures (MTBF) of 470 hours and a Mean Time To Repair (MTTR) of 30 hours. What is its availability?

  1. 6.0%
  2. 94.0%
  3. 93.6%
  4. 98.0%
Show answer & explanation

Correct answer: B - 94.0%

Question 5

In a well-run maintenance organization, what is the correct relationship between planning and scheduling a job?

  1. Scheduling is completed first so that the planner knows the deadline to work back from
  2. Planning and scheduling are really the same activity, normally performed by one person
  3. Scheduling defines the parts and procedures, and planning then assigns the right technician
  4. The job is fully planned first, then scheduled once resources and parts are ready
Show answer & explanation

Correct answer: D - The job is fully planned first, then scheduled once resources and parts are ready

Question 6

Using ABC analysis to manage a maintenance storeroom, how should the relatively few 'A' items be characterized and controlled?

  1. The few items holding the greatest share of value, given the tightest control
  2. The physically largest items, stored nearest the storeroom door for fast access
  3. The cheapest, fastest-moving items, reordered in bulk with minimal oversight
  4. Emergency-only items that are deliberately exempted from routine cycle counting
Show answer & explanation

Correct answer: A - The few items holding the greatest share of value, given the tightest control

Question 7

A production line runs at 95% availability, 90% performance, and 99% quality. What is its Overall Equipment Effectiveness (OEE)?

  1. 94.7%
  2. 95.0%
  3. 84.6%
  4. 85.5%
Show answer & explanation

Correct answer: C - 84.6%

Question 8

A reliability improvement project requires a one-time investment of $60,000 and is expected to save $24,000 per year. Using the simple payback method, what is the payback period?

  1. 0.4 years
  2. 2.5 years
  3. 40 years
  4. 3.6 years
Show answer & explanation

Correct answer: B - 2.5 years

Question 9

Under OSHA's Control of Hazardous Energy (Lockout/Tagout) standard, a machine operator who runs equipment that is about to be serviced by a millwright - but who performs no part of the servicing - is classified as which type of employee?

  1. Authorized employee
  2. Competent person
  3. Qualified employee
  4. Affected employee
Show answer & explanation

Correct answer: D - Affected employee

Question 10

Occupants of a building report headaches and eye irritation that consistently clear up after they leave for the day, yet no specific illness or single contaminant can be identified. This pattern is BEST described as:

  1. Sick Building Syndrome
  2. Building-Related Illness
  3. Legionnaires' disease
  4. Carbon monoxide poisoning
Show answer & explanation

Correct answer: A - Sick Building Syndrome
