1. Which Connecticut glazier license classification is most directly
associated with installing, maintaining, or repairing glass in residential
or commercial structures?
A. AG-1 Automotive Glass Contractor
B. AG-2 Automotive Glass Journeyperson
C. FG-1 Flat Glass Contractor
D. FG-2 Flat Glass Journeyperson
Answer: C. FG-1 Flat Glass Contractor
Rationale: The FG-1 classification is the Connecticut contractor license
associated with flat glass work in residential and commercial structures,
while FG-2 is the corresponding journeyperson classification.
, 2. A glazier is preparing to install a large insulated glass unit in an
aluminum storefront frame. What is the primary purpose of setting
blocks?
A. To increase the visible glass area
B. To support and properly position the glass within the frame
C. To permanently bond the glass to the frame
D. To prevent ultraviolet radiation from entering the building
Answer: B. To support and properly position the glass within the frame
Rationale: Setting blocks support the weight of the glass, maintain proper
edge clearances, and transfer loads to appropriate portions of the framing
system.
3. Which type of glass is produced by heating annealed glass and then
rapidly cooling it to create increased strength and a safer break
pattern?
A. Laminated glass
B. Wired glass
C. Tempered glass
D. Patterned glass
Answer: C. Tempered glass
,Rationale: Tempered glass is heat-treated and rapidly cooled, producing
greater resistance to thermal and mechanical stresses and causing it to
break into relatively small granular pieces.
4. What is the principal safety advantage of laminated glass?
A. It cannot break under any circumstances
B. Its interlayer helps retain broken glass fragments
C. It eliminates the need for structural framing
D. It always has greater thermal insulation than insulated glass
Answer: B. Its interlayer helps retain broken glass fragments
Rationale: Laminated glass consists of glass layers bonded to an interlayer,
allowing broken fragments to remain attached to the interlayer rather
than falling freely.
5. Before installing a replacement pane into an existing frame, what
should the glazier do first?
A. Apply sealant to the entire glass surface
B. Verify the opening dimensions, frame condition, and required clearances
C. Remove all drainage paths
D. Paint the glass edges
Answer: B. Verify the opening dimensions, frame condition, and required
clearances
, Rationale: Proper measurement and inspection help ensure that the
replacement glass fits correctly and that the existing frame can safely
receive the new unit.
6. What is the primary purpose of an insulating glass unit's spacer?
A. To sharpen the glass edge
B. To separate the panes and help maintain the insulating cavity
C. To prevent all visible reflections
D. To replace the glazing sealant
Answer: B. To separate the panes and help maintain the insulating cavity
Rationale: The spacer maintains the designed separation between panes
and forms part of the perimeter seal that protects the insulating cavity.
7. Which condition is most likely to cause premature failure of an
insulated glass unit?
A. Proper edge clearance
B. Correct setting blocks
C. Damage to the perimeter seal
D. Proper drainage
Answer: C. Damage to the perimeter seal
