1. A Plant Utilities Assistant working in a hospital central plant is
responsible for supporting the operation and maintenance of critical
utility systems. Which of the following best describes the primary
purpose of plant utilities operations in a healthcare facility?
A. To provide only administrative support for hospital departments
B. To maintain reliable operation of mechanical, electrical, plumbing, and
utility systems required for patient care
C. To perform only exterior building maintenance activities
D. To replace all hospital engineering staff during emergencies
Answer: B
,Plant utilities personnel support essential infrastructure such as heating,
cooling, power, water, and steam systems because uninterrupted utility
service is necessary for safe hospital operations and patient care.
2. A Plant Utilities Assistant is inspecting a steam boiler room and notices
a leaking steam valve. What should be the first action taken?
A. Ignore the leak if the boiler is still producing steam
B. Increase system pressure to compensate for the leak
C. Report the condition and follow proper safety procedures before
attempting repairs
D. Cover the valve with insulation without shutting down equipment
Answer: C
Steam leaks can cause burns, equipment damage, and energy loss, so the
condition must be reported and addressed using approved safety
procedures rather than ignored or temporarily concealed.
3. In a hospital facility, why is preventive maintenance performed on
pumps, motors, and other mechanical equipment?
A. To increase equipment failure frequency
B. To identify problems before breakdowns occur and extend equipment life
C. To eliminate the need for inspections
D. To reduce the need for operating records
Answer: B
,Preventive maintenance involves scheduled inspections, lubrication,
adjustments, and repairs designed to prevent unexpected failures and
maintain reliable equipment operation.
4. A centrifugal pump used in a building utility system fails to circulate
water. Which condition is most likely to cause this problem?
A. Proper alignment of the pump shaft
B. Adequate lubrication of bearings
C. Loss of prime or air entering the suction line
D. Correct motor voltage supply
Answer: C
Centrifugal pumps require proper suction conditions and a filled pump
casing. Loss of prime or air leakage can prevent normal water circulation.
5. When working around rotating mechanical equipment, a Plant Utilities
Assistant should always:
A. Wear loose clothing for comfort
B. Remove machine guards for easier inspection
C. Follow lockout/tagout procedures before servicing equipment
D. Place tools directly on moving equipment
Answer: C
Lockout/tagout procedures prevent accidental startup of equipment during
maintenance and protect workers from serious injury.
, 6. The purpose of a pressure gauge installed on a steam or water system
is to:
A. Measure electrical current
B. Indicate system pressure conditions
C. Control room temperature
D. Measure motor speed
Answer: B
Pressure gauges provide operators with information about system
operating conditions and help identify abnormal pressure levels.
7. In a hospital, emergency generators are primarily installed to:
A. Replace all normal electrical service permanently
B. Provide backup power during utility outages
C. Reduce the need for electrical maintenance
D. Supply only lighting in parking areas
Answer: B
Emergency generators provide temporary electrical power to essential
systems when normal utility power is interrupted.
8. A Plant Utilities Assistant observing an unusually high temperature on
a motor bearing should recognize that this may indicate:
A. Proper operation under all conditions
B. Possible lubrication problems or mechanical failure
