1. A Senior Sheet Metal Worker assigned to a hospital facility is reviewing
plans for a new HVAC duct system installation. Which factor is most
important when determining the proper duct size before fabrication begins?
A. The color of the duct insulation
B. The required airflow volume and system pressure requirements
C. The brand name of the sheet metal supplier
D. The number of workers assigned to the project
Answer: B
The duct size must be determined from airflow requirements, velocity
limitations, and pressure considerations to ensure the HVAC system
operates efficiently and delivers proper air distribution throughout the
facility.
, 2. A sheet metal worker is installing rectangular ductwork in a medical
facility where minimizing air leakage is critical. Which fabrication
practice best improves duct system performance?
A. Increasing the duct joint spacing
B. Leaving seams unsealed for future adjustments
C. Properly sealing seams and joints according to specifications
D. Using thinner metal to reduce weight
Answer: C
Proper sealing of seams and joints reduces air leakage, improves energy
efficiency, and helps maintain required airflow conditions in critical
healthcare environments.
3. Before cutting sheet metal using power shears, what should a Senior
Sheet Metal Worker verify first?
A. That the metal has been painted
B. That the cutting tool is appropriate and safety guards are functioning
C. That the sheet is stored outdoors
D. That the finished product has already been inspected
Answer: B
Checking tool suitability and safety features before operation prevents
injuries and ensures accurate cutting of sheet metal materials.
, 4. Which tool is commonly used to measure and mark straight lines on
sheet metal before fabrication?
A. Pipe wrench
B. Torpedo level only
C. Combination square and marking tools
D. Chain hoist
Answer: C
A combination square and proper marking tools allow workers to create
accurate layout lines necessary for precise fabrication and assembly.
5. When installing ductwork above a hospital ceiling, why is proper
support spacing important?
A. It changes the color of the duct system
B. It prevents sagging, vibration, and structural failure
C. It eliminates the need for insulation
D. It increases the thickness of the metal
Answer: B
Correct support spacing maintains duct alignment, prevents excessive
loading, and reduces vibration-related problems during system operation.
6. A Senior Sheet Metal Worker must interpret HVAC drawings. Which
drawing information is most important for duct installation?
, A. The architect’s preferred paint colors
B. Duct dimensions, locations, elevations, and connection details
C. The contractor’s office location
D. The manufacturer’s advertising information
Answer: B
Construction drawings provide essential information about duct sizes,
routing, elevations, and connections required for accurate installation.
7. Which material is commonly used for HVAC duct fabrication because
of its corrosion resistance and durability?
A. Galvanized steel
B. Untreated wood
C. Rubber tubing
D. Copper wire
Answer: A
Galvanized steel is widely used in duct fabrication because its zinc coating
provides corrosion resistance and extends service life.
8. When cutting galvanized sheet metal, what personal protective
equipment is most appropriate?
A. Safety glasses and cut-resistant gloves
B. Sandals and cloth gloves
