1. A Plant Utilities Engineer working in a large healthcare facility is
responsible for maintaining continuous operation of critical building
systems. Which of the following best describes the primary purpose of
a hospital plant utilities department?
A. To provide only cosmetic improvements to patient areas
B. To maintain reliable operation of mechanical, electrical, plumbing, steam,
and utility systems required for safe facility operation
C. To manage only office equipment and computer networks
D. To perform only emergency repairs after equipment failure
Answer: B
,The plant utilities department ensures that essential infrastructure systems
such as heating, cooling, steam, water, power distribution, and mechanical
equipment remain operational because hospitals depend on these systems
for patient care, safety, and regulatory compliance.
2. A centrifugal pump is operating but delivering significantly reduced
flow. The engineer checks for common causes. Which condition is
most likely to reduce pump performance?
A. Proper alignment of the pump and motor
B. Increased lubrication of bearings
C. Air entering the suction line or pump cavitation
D. Correct operating pressure
Answer: C
Air leaks and cavitation can interrupt smooth fluid movement through a
centrifugal pump, causing reduced capacity, vibration, noise, and possible
equipment damage.
3. In a hospital steam distribution system, the primary function of a
steam trap is to:
A. Increase steam pressure above boiler pressure
B. Remove condensate and non-condensable gases while preventing
,unnecessary steam loss
C. Add water into the steam system
D. Reduce boiler firing temperature
Answer: B
Steam traps automatically discharge condensate and gases from steam
systems while conserving live steam, improving efficiency and preventing
water hammer.
4. A boiler operator observes that boiler water level is rapidly fluctuating.
Which device is designed to maintain proper water level
automatically?
A. Feedwater regulator or level control system
B. Pressure reducing valve
C. Flame scanner
D. Safety relief valve
Answer: A
Automatic feedwater controls monitor boiler water level and adjust
feedwater flow to maintain safe operating conditions and prevent low-
water or overfill conditions.
5. The purpose of a boiler safety relief valve is to:
, A. Increase combustion efficiency
B. Prevent excessive pressure buildup that could damage the boiler
C. Remove dissolved solids from water
D. Control burner ignition timing
Answer: B
Safety relief valves protect pressure vessels by automatically opening when
pressure exceeds safe limits, preventing catastrophic failure.
6. In a chilled water HVAC system, the evaporator performs which
function?
A. Rejects heat to outdoor air
B. Absorbs heat from building spaces into the refrigerant
C. Compresses refrigerant vapor
D. Controls electrical power supply
Answer: B
The evaporator absorbs heat from chilled water or conditioned air,
allowing the refrigeration cycle to remove heat from occupied spaces.
7. A Plant Utilities Engineer notices excessive vibration from a rotating
motor. The first step should generally be to:
