Nevada C-8 Glass & Glazing Contractor Licensing
Exam – Comprehensive 150-Question Practice Test |
Nevada State Contractors Board | Glass & Glazing
Contracting | Correct Answers & Detailed Rationales
Description: This comprehensive examination is designed for candidates
preparing for the Nevada C-8 Glass and Glazing Contractor license
exam. The assessment covers all required content areas including NAC
624.260 scope of work, 2024 International Building Code (IBC) glazing
requirements, ASTM E1300 load resistance standards, safety glazing
classifications, OSHA silica exposure regulations, business management,
estimating, project scheduling, and Nevada-specific contracting laws.
Based on official Nevada State Contractors Board curriculum, this exam
tests both recall and application-level reasoning expected of competent
glass and glazing contractors .
SECTION 1: QUESTIONS 1-50
Question 1
A contractor holding a standard Nevada C-8 license is requested to
install a structural steel framework to support a new commercial glass
storefront. Based on NAC 624.260, which action is the MOST
ACCURATE?
,2|Page
A) Proceed with the installation if the steel framework represents less
than 10 percent of the total project cost
B) Install the steel framework, provided a licensed structural engineer
stamps the architectural blueprints
C) Subcontract the structural steel erection to a licensed contractor, or
decline that specific portion of the bid
D) Proceed using a temporary Class A General Engineering license
extension filed with the Board
Answer: C
*Nevada does not permit out-of-scope structural steel work under a C-8
license regardless of cost percentage. Engineering stamps validate the
design, not the contractors legal license classification to perform the
physical labor. The Nevada State Contractors Board (NSCB) does not
grant temporary classification extensions for out-of-scope structural
work. Bidding outside the established license classification renders the
contract legally void under NRS 624.640 .*

Question 2
An architect specifies a multi-pane insulating glass unit (IGU) for a
ground-floor storefront hazardous location. Based on IBC 2024 Chapter
24, which configuration is MOST ACCURATE?
,3|Page
A) Only the outboard pane requires safety glazing to resist windborne
debris
B) Only the inboard pane requires safety glazing to protect interior
occupants
C) Every pane in the IGU must be safety glazed if any pane is in a
hazardous location
D) No safety glazing is required for IGUs in storefront applications
Answer: C
*When an IGU is used in a hazardous location, every pane within the
unit must be safety glazed. This prevents injury from broken glass even
if one pane remains intact, as the failure of any layer compromises the
unit's safety integrity. ASTM and ANSI standards outline safety glazing
requirements for these applications .*

Question 3
According to the 2024 International Building Code (IBC), what is the
maximum opening allowed in a guardrail infill?
A) 2 inches
B) 4 inches
, 4|Page
C) 6 inches
D) 8 inches
Answer: B
*Guards must be designed so that a 4-inch diameter sphere cannot pass
through any opening. This 4-inch rule is designed to prevent small
children from falling through the railing. On stairs, a slightly larger 4
and 3/8 inch sphere is sometimes permitted for the triangle formed by
the riser and tread .*

Question 4
What is the primary risk associated with dry sweeping or using
compressed air for cleaning silica dust on a job site?
A) It damages the glass surface
B) It wastes water
C) It creates respirable dust that causes silicosis
D) It attracts insects
Answer: C
