CERTIFICATION EXAM QUESTIONS
AND ANSWERS 2026/2027
1. According to ASTM C1036, which quality level of flat glass is generally used for high-quality
mirrors?
A. Q3
B. Q2
C. Q1
D. Q4
Answer: C
Conceptual Explanation: Q1 is the highest quality level for flat glass intended for high-
quality mirrors and similar applications according to ASTM C1036.
2. In the High Velocity Hurricane Zone (HVHZ), what is the maximum allowable deflection for
a structural member supporting glass?
A. L/120
B. L/360
,C. L/240
D. L/175
Answer: D
Conceptual Explanation: Florida Building Code (HVHZ) specifies that the deflection of
structural members supporting glass shall not exceed L/175.
3. According to OSHA 1926.451, at what height is fall protection required for employees
working on scaffolds?
A. 6 feet
B. 10 feet
C. 8 feet
D. 12 feet
Answer: B
Conceptual Explanation: OSHA requires each employee on a scaffold more than 10 feet
above a lower level to be protected from falling.
4. Which type of glass is required by the FBC for sloped glazing installed more than 15 degrees
from vertical?
A. Laminated glass
B. Heat-strengthened glass
C. Annealed glass
, D. Wired glass only
Answer: A
Conceptual Explanation: For safety, laminated glass is typically required for sloped
glazing to prevent glass from falling out of the frame if broken.
