1. A supervising steamfitter in a large hospital complex is assigned
responsibility for coordinating the replacement of a high-pressure
steam main serving surgical suites, sterilizers, and domestic hot water
heat exchangers. Before authorizing isolation of the affected section,
which action is the most appropriate to ensure continuity of critical
hospital operations while maintaining worker safety?
A. Shut down the steam supply immediately because patient safety requires
immediate repairs.
B. Coordinate with plant operations, clinical departments, and
maintenance personnel to establish temporary service, verify isolation
,procedures, implement lockout/tagout, and schedule work during the least
disruptive period.
C. Leave the system in operation while workers remove the damaged pipe.
D. Drain only the condensate system and proceed without notifying hospital
departments.
Rationale: Hospital steam systems serve life-safety and patient-care
equipment. Supervisors must coordinate operations, ensure proper
isolation, implement lockout/tagout procedures, communicate with
affected departments, and minimize disruptions while protecting personnel
and patients.
2. When supervising the installation of Schedule 80 carbon steel steam
piping operating above 150 psig, the primary reason for verifying that
pipe supports are installed according to the approved drawings is to:
A. Reduce painting costs.
B. Improve the appearance of the piping system.
C. Prevent excessive pipe stress, maintain alignment, accommodate
thermal expansion, and protect connected equipment.
D. Eliminate the need for expansion joints.
Rationale: Properly designed and installed supports carry pipe loads,
control movement during expansion, prevent sagging, and reduce stresses
on valves, pumps, boilers, and other connected equipment.
, 3. During inspection of a steam distribution system, a supervisor
observes repeated failures of thermostatic steam traps serving heat
exchangers. Which underlying condition should be investigated first?
A. Excessive insulation thickness.
B. Oversized condensate receivers.
C. Water hammer, dirt accumulation, incorrect trap selection, or operating
conditions exceeding trap design limits.
D. Low ambient temperatures around the piping.
Rationale: Steam trap failures are commonly caused by contamination,
water hammer, improper sizing, incorrect application, or operating
pressures beyond design specifications.
4. A supervising steamfitter reviewing welding documentation should
verify that welders performing pressure piping work are qualified in
accordance with applicable codes because:
A. Qualified welders work faster.
B. Qualification reduces material costs.
C. Pressure piping weld quality directly affects system integrity, safety,
reliability, and code compliance.
D. Qualification is required only for stainless steel piping.
Rationale: Pressure piping welds must meet established code requirements
to ensure structural integrity, prevent leaks, and maintain safe operation
under pressure.
, 5. A hospital's condensate return temperature has decreased significantly
over several weeks despite constant steam demand. Which condition
is the most likely cause?
A. Increased boiler pressure only.
B. New insulation on condensate piping.
C. Steam trap failures allowing steam loss or condensate bypass, resulting
in reduced condensate recovery efficiency.
D. Higher feedwater temperature.
Rationale: Failed steam traps reduce condensate recovery efficiency and
waste steam, lowering condensate temperatures returning to the boiler
plant.
6. Which valve is generally preferred for throttling steam flow because it
provides better flow regulation than a gate valve?
A. Plug valve.
B. Ball valve.
C. Globe valve.
D. Check valve.
Rationale: Globe valves are specifically designed for throttling and
regulating flow, whereas gate valves are intended primarily for full open or
full closed service.
