FLORIDA GLASS AND GLAZING
CONTRACTOR EXAM QUESTIONS AND
ANSWERS
1. According to the Florida Building Code, what is the maximum area of a single pane of
annealed glass allowed in a ‘hazardous location’ if it is not protected by a protective bar?
A. 9 square feet
B. 0 square feet (None allowed)
C. 16 square feet
D. 24 square feet
Answer: B
Conceptual Explanation: Glazing in hazardous locations, such as doors and large panels
near walking surfaces, must be safety glazing (tempered or laminated). Annealed glass is
generally prohibited in these specific locations regardless of size unless specific
exemptions apply.
2. In the High Velocity Hurricane Zone (HVHZ), glass used in buildings must be tested for large
missile impact. What is the weight and velocity of the missile used in the Level D test?
A. 2lb 2x4 traveling at 50 fps
,B. 9lb 2x4 traveling at 50 fps
C. 9lb 2x4 traveling at 34 fps
D. 4lb 2x4 traveling at 40 fps
Answer: B
Conceptual Explanation: The large missile impact test for HVHZ requires a 9-pound 2x4
timber to be fired at a velocity of 50 feet per second.
3. Which type of sealant is most recommended for structural silicone glazing (SSG) due to its
high tensile strength and UV resistance?
A. Neutral-cure silicone
B. Polyurethane sealant
C. Acetoxy-cure silicone
D. Acrylic latex
Answer: A
Conceptual Explanation: Neutral-cure silicones are required for structural glazing
because they do not produce acidic byproducts that corrode metal components and have
superior adhesion to glass.
4. Under OSHA 1926 Subpart M, at what height is fall protection required for employees
working on a walking/working surface with an unprotected side?
A. 4 feet
, B. 10 feet
C. 6 feet
D. 15 feet
Answer: C
Conceptual Explanation: OSHA’s general rule for the construction industry requires fall
protection (guardrails, nets, or personal fall arrest systems) starting at 6 feet.
5. A standard 1/4-inch (6mm) thick piece of plate glass weighs approximately how many
pounds per square foot?
A. 1.54 lbs
B. 2.12 lbs
C. 5.00 lbs
D. 3.27 lbs
Answer: D
Conceptual Explanation: Glass weighs approximately 13 pounds per square foot per inch
of thickness. Therefore, 1/4 inch glass is = 3.25 to 3.27 lbs per square foot.
6. What is the primary purpose of a ‘setting block’ in a glazing system?
A. To support the weight of the glass and prevent glass-to-metal contact
B. To provide a water-tight seal
