Sample Practice Questions

Try these 10 sample questions from the Red Seal Glazier Examination practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

1. 1A glazier orders a replacement shackle for a rigging assembly. Which dimension is used to designate the shackle size?

   1. A.The diameter of the shackle pin
   2. B.The diameter of the shackle bowCorrect answer: B
   3. C.The width between the shackle eyes
   4. D.The length of the shackle pin

   Explanation: CCOHS states that "Shackles are sized according to the diameter of the bow section rather than the pin size." The bow diameter determines the designation; the other dimensions are not the size designation.

   Reference: CCOHS Materials Handling - Use of Shackles — What are the types of shackles that you can choose?

2. 2While glazing a commercial frame, a glazier needs components that will support the bottom edge of the glass. Which components serve that function?

   1. A.Setting blocksCorrect answer: A
   2. B.Shear blocks
   3. C.Anti-walk blocks
   4. D.Frame spigots

   Explanation: The GANA glazing guidance states, "The proper sizing and design of the setting blocks assure full bearing of the glass on them". Setting blocks support the glass; anti-walk blocks control movement, while shear blocks and spigots connect frame members.

   Reference: NGA GANA Glazing Manual, IYOG Edition — General Guidelines for Glazing, setting blocks, page 98

3. 3A glazier is identifying a residential window that is hinged along its top edge and swings outward. What type of window is it?

   1. A.AwningCorrect answer: A
   2. B.Casement
   3. C.Hopper
   4. D.Guillotine

   Explanation: The Glazier occupational standard defines an awning window as a "window that is hinged at the top and swings out". That matches the hinge position and direction described.

   Reference: Red Seal Occupational Standard - Glazier — Appendix C, Glossary, awning (window), page 118

4. 4A glazier is selecting a residential mirror made with an adhesive-backed polyethylene sheet on the back of annealed glass. What is the intended function of that sheet?

   1. A.Retain fragments of the broken glassCorrect answer: A
   2. B.Protect the metal layer from corrosion
   3. C.Reduce the amount of reflected light
   4. D.Resist moisture attack on the coating

   Explanation: The glazing manual says, "The backing material does not prevent breakage of mirrors, but lessens the potential of injury on impact by retaining the fragments." The film addresses fragment retention after breakage.

   Reference: NGA GANA Glazing Manual, IYOG Edition — Mirrors, Silvered Safety Mirrors, page 44

5. 5A glazier finds that debris has blocked the weep system beneath an insulating glass unit. Which mechanism most directly threatens the unit's edge seal as a result?

   1. A.Prolonged moisture at the edge sealCorrect answer: A
   2. B.Sustained pressure at the edge seal
   3. C.Chemical attack at the edge seal
   4. D.Thermal stress at the edge seal

   Explanation: The GANA manual states, "Avoid improper or inoperative weep systems, which may leave water trapped in the system, causing premature failure of the IGU seals." The blocked drainage path can retain moisture at the edge seal.

6. 6A glazier checks CCOHS guidance for an elastomer-impregnated metal-mesh sling before a lift. What is the upper end of the temperature range listed for that sling type?

   1. A.93°CCorrect answer: A
   2. B.204°C
   3. C.288°C
   4. D.425°C

   Explanation: CCOHS states that "Those impregnated with elastomer have a narrower temperature work range (-18°C to 93°C)." It advises consulting the manufacturer for work outside that range.

   Reference: CCOHS Materials Handling - Metal Mesh Slings — What are the characteristics of metal mesh slings?

7. 7A glazier uses the GANA general sizing rule for each setting block in a metal glazing system, not a neoprene lock-strip system. The lite measures 8 feet by 5 feet. What block length does the rule calculate for each block?

   1. A.0.4 inch
   2. B.2.0 inches
   3. C.4.0 inchesCorrect answer: C
   4. D.16.0 inches

   Explanation: The manual says, "Generally, each setting block, in most metal glazing systems, is 0.1 inch per square foot of glass area." The area is 8 × 5 = 40 square feet, so 40 × 0.1 = 4.0 inches per block. Using 0.01 inch per square foot gives 0.4 inch; incorrectly halving the result gives 2.0 inches; using the 0.4-inch lock-strip multiplier gives 16.0 inches.

   Reference: NGA GANA Glazing Manual, IYOG Edition — General Guidelines for Glazing, setting block sizing, page 98

8. 8A glazier is explaining the construction of a sealed residential insulating glass unit. Which component in its spacer absorbs residual moisture after the unit is sealed?

   1. A.DesiccantCorrect answer: A
   2. B.Low-e coating
   3. C.Inert gas
   4. D.Thermal break

   Explanation: Natural Resources Canada states, "The spacer bar has a desiccant in it that absorbs moisture after the unit is sealed to prevent fogging." The other items address heat transfer or insulation rather than that moisture-absorption function.

9. 9A glazier is identifying a commercial specialty glass product made by permanently bonding two annealed glass lites with a continuous plastic interlayer. What is this construction called?

   1. A.Laminated glassCorrect answer: A
   2. B.Monolithic wired glass
   3. C.Heat-strengthened glass
   4. D.Air-spaced insulating glass

   Explanation: The glazing manual states, "Laminated glass is traditionally defined as two or more lites of glass permanently bonded together with one or more interlayers." The described two-lite construction meets that definition.

   Reference: NGA GANA Glazing Manual, IYOG Edition — Types of Laminated Glazing

10. 10A homeowner asks a glazier to compare replacement windows by how much of the sun's heat each product admits. Which performance rating should the glazier compare?

    1. A.U-factor
    2. B.Solar heat gain coefficientCorrect answer: B
    3. C.Energy Rating
    4. D.Visible transmittance

    Explanation: Natural Resources Canada defines "Solar heat gain coefficient (SHGC)—a ratio showing the amount of the sun’s heat that can pass through the product." U-factor measures heat transfer; Energy Rating combines factors; visible transmittance concerns light.
