1. A supervising sheet metal worker in a healthcare facility is responsible
for coordinating installation and maintenance work while ensuring
compliance with safety standards, infection control procedures, and
building requirements. When planning a major ductwork replacement
project inside an operating hospital area, what should be the
supervisor’s first priority before work begins?
A. Ordering additional sheet metal materials to avoid delays
B. Reviewing infection control requirements, work permits, and safety
procedures with all involved personnel
C. Assigning the most experienced worker to complete the duct installation
,alone
D. Beginning demolition immediately to reduce project completion time
Answer: B
A healthcare facility requires strict coordination before construction
activities begin. Reviewing infection control measures, permits, and safety
procedures protects patients, workers, and facility operations.
2. A supervisor is inspecting a rectangular HVAC duct system and notices
excessive air leakage at several transverse joints. Which corrective
action is most appropriate?
A. Increase the fan speed to compensate for lost airflow
B. Apply approved duct sealant or sealing methods to the leaking joints
C. Replace all ductwork regardless of the leakage amount
D. Reduce the size of the supply duct opening
Answer: B
Proper duct sealing reduces energy loss, improves system efficiency, and
ensures the HVAC system delivers the designed airflow performance.
3. When supervising sheet metal fabrication, which measurement
principle is most important for ensuring that fabricated duct
components fit correctly during installation?
A. Measuring only the exterior dimensions of the duct
B. Allowing installers to modify all components in the field
,C. Taking accurate measurements and verifying dimensions before
fabrication
D. Using standard dimensions without checking drawings
Answer: C
Accurate measurements and verification prevent fabrication errors, reduce
material waste, and ensure proper installation according to design
specifications.
4. A supervising sheet metal worker reviews mechanical drawings before
beginning a project. What information can typically be obtained from
these drawings?
A. Employee payroll schedules
B. Duct sizes, locations, equipment connections, and installation
requirements
C. Patient medical information
D. Material supplier contracts
Answer: B
Mechanical drawings provide essential information about system layout,
dimensions, equipment connections, and installation requirements needed
for successful HVAC work.
5. During installation of large ductwork above a hospital ceiling, what
safety practice should the supervisor enforce?
, A. Allow workers to remove protective equipment for comfort
B. Ensure proper fall protection and secure lifting procedures are followed
C. Permit workers to stand beneath suspended loads
D. Eliminate all inspections to increase productivity
Answer: B
Large overhead duct installations involve fall and lifting hazards. Proper
fall protection and safe material handling procedures are required to
prevent injuries.
6. The primary purpose of a duct transition fitting is to:
A. Increase noise levels in the HVAC system
B. Connect two sections of ductwork with different shapes or sizes efficiently
C. Replace all insulation requirements
D. Eliminate the need for air balancing
Answer: B
Transition fittings allow smooth airflow between duct sections of different
dimensions while minimizing turbulence and pressure loss.
7. A supervisor notices that a worker is using a damaged power tool
during fabrication. What action should be taken?
A. Allow the worker to finish the task quickly
B. Remove the tool from service and replace or repair it
