1. A Supervising Maintenance Mechanic working in a large healthcare
facility is responsible for coordinating preventive maintenance
programs, assigning work orders, and ensuring equipment reliability.
Which of the following best describes the primary purpose of
preventive maintenance in a hospital mechanical systems
environment?
A. To wait until equipment fails before performing repairs
B. To reduce unexpected failures by inspecting, servicing, and correcting
equipment before breakdowns occur
C. To eliminate the need for skilled maintenance personnel
D. To increase equipment operation beyond manufacturer limitations
,Answer: B
Preventive maintenance is designed to identify wear, deterioration, and
developing problems before equipment failure occurs, improving reliability,
safety, and operational continuity in critical facilities such as hospitals.
2. A maintenance supervisor receives a report that a critical air-handling
unit serving patient areas has stopped operating. What should be the
supervisor’s first action after receiving the emergency notification?
A. Immediately order replacement equipment without inspection
B. Review the situation, verify safety conditions, and dispatch qualified
personnel to assess the failure
C. Ignore the issue until the next scheduled maintenance period
D. Shut down all building systems to prevent further problems
Answer: B
A supervising mechanic must first evaluate the emergency, confirm safe
working conditions, and assign appropriate personnel to diagnose and
restore critical systems efficiently.
3. When supervising mechanical maintenance staff, a supervisor must
ensure compliance with workplace safety procedures. Which safety
practice is required before servicing energized electrical or mechanical
equipment?
,A. Increasing equipment speed to locate the problem
B. Applying lockout/tagout procedures to isolate hazardous energy sources
C. Removing all warning labels from equipment
D. Allowing only untrained employees to perform repairs
Answer: B
Lockout/tagout procedures prevent accidental energization of equipment
during maintenance by isolating energy sources and protecting workers
from serious injury.
4. A maintenance mechanic reports that a centrifugal pump is vibrating
excessively. Which condition is a likely cause of this problem?
A. Proper alignment and balanced operation
B. Correct lubrication levels and stable mounting
C. Misalignment, imbalance, worn bearings, or cavitation
D. Normal operation requiring no investigation
Answer: C
Excessive pump vibration commonly results from mechanical problems
such as shaft misalignment, imbalance, bearing failure, or cavitation and
requires inspection to prevent further damage.
5. A Supervising Maintenance Mechanic reviews maintenance records
and notices repeated failures of the same motor. What is the most
effective management response?
, A. Continue replacing the motor without investigating
B. Perform a root cause analysis to determine why failures are occurring
C. Remove the motor from service permanently
D. Ignore the records because previous repairs were completed
Answer: B
Root cause analysis identifies underlying problems such as electrical faults,
improper installation, overload conditions, or operating issues instead of
repeatedly treating only the symptoms.
6. In a hospital environment, why is maintaining reliable mechanical
systems especially important?
A. Mechanical systems only affect employee comfort
B. Mechanical failures can affect patient safety, infection control, and
essential operations
C. Mechanical systems are unrelated to healthcare services
D. Hospitals can operate normally without HVAC and utility systems
Answer: B
Healthcare facilities depend on reliable mechanical systems for ventilation,
temperature control, equipment operation, and maintaining safe patient
environments.
7. A supervisor assigns a mechanic to inspect a steam boiler. Which
condition requires immediate attention?
