Prep & Study Guide
1. What is the primary purpose of safety glazing in a hazardous location?
A. Improve thermal performance
B. Reduce the likelihood of injury when glass breaks
C. Increase visible light transmission
D. Prevent condensation
Answer: Reduce the likelihood of injury when glass breaks
Rationale: Safety glazing is designed to reduce the risk of cutting or piercing
injuries when glass is subjected to human impact or otherwise breaks in a
hazardous location.
2. Which type of glass is generally considered safety glazing when properly
manufactured and permanently marked?
,A. Annealed glass
B. Mirror glass
C. Tempered glass
D. Float glass
Answer: Tempered glass
Rationale: Tempered glass is heat-treated to increase strength and cause it to
fracture into relatively small granular particles rather than large sharp shards.
3. What is the principal difference between tempered and heat-strengthened
glass?
A. Tempered glass is laminated while heat-strengthened glass is not
B. Tempered glass has greater surface compression and typically breaks into
smaller particles
C. Heat-strengthened glass cannot be used outdoors
D. Tempered glass is always thicker
Answer: Tempered glass has greater surface compression and typically breaks
into smaller particles
Rationale: Both are heat-treated, but fully tempered glass achieves higher
surface compression and is intended for applications requiring safety glazing
characteristics.
4. Which glass construction provides a retained-glass safety feature after
breakage?
A. Annealed monolithic glass
B. Laminated glass
C. Polished plate glass
D. Tinted annealed glass
Answer: Laminated glass
Rationale: Laminated glass contains an interlayer that tends to hold broken
glass fragments together after the glass fractures.
, 5. A glazing contractor is replacing a large pane located adjacent to a
pedestrian door. What is the first code-related consideration?
A. Paint color
B. Whether the pane is in a hazardous location requiring safety glazing
C. Whether the frame is aluminum
D. Whether the glass has a low-emissivity coating
Answer: Whether the pane is in a hazardous location requiring safety glazing
Rationale: Glazing near doors and other impact-prone locations can present a
significant injury hazard and must be evaluated for safety-glazing requirements.
6. Why should glass dimensions generally be verified at the jobsite before
fabrication?
A. Glass dimensions never correspond to drawings
B. Field conditions, frame dimensions, and tolerances can differ from plans
C. Manufacturers require every pane to be undersized
D. It eliminates the need for shop drawings
Answer: Field conditions, frame dimensions, and tolerances can differ from
plans
Rationale: Accurate field measurements help prevent oversized or undersized
units and account for actual frame conditions, construction tolerances, and
installation requirements.
7. What is the primary purpose of providing edge clearance around a glass
lite?
A. Increase glass color
B. Allow for thermal movement, fabrication tolerances, and frame movement
C. Reduce glass thickness
D. Increase solar heat gain
Answer: Allow for thermal movement, fabrication tolerances, and frame
movement
, Rationale: Glass should not be forced tightly against framing because
movement or dimensional changes can transfer damaging stresses to the glass.
8. What is the most appropriate action when a glass lite is chipped deeply at
an edge before installation?
A. Install it with the damaged edge facing upward
B. Hide the chip with sealant
C. Evaluate it against manufacturer and project requirements and replace it if
unacceptable
D. Grind the chip with a screwdriver
Answer: Evaluate it against manufacturer and project requirements and replace
it if unacceptable
Rationale: Edge damage can reduce glass strength and create stress
concentrations. Significant damage should not be concealed and ignored.
9. What is the purpose of setting blocks beneath a glass lite?
A. Provide structural support and maintain proper positioning
B. Increase glass transparency
C. Replace all perimeter sealants
D. Eliminate frame movement
Answer: Provide structural support and maintain proper positioning
Rationale: Properly located setting blocks transfer the glass load to the framing
system while maintaining designed clearances.
10.Which material is commonly used for setting blocks because it provides
resilient support and is compatible with many glazing systems?
A. Untreated wood only
B. Appropriate neoprene or compatible elastomeric material
C. Drywall compound
D. Cement mortar
