MULTIPLE CHOICE QUESTIONS
1. What is the primary purpose of spray-applied fireproofing (SAFX)?
A. To improve the aesthetic appearance of structural members
B. To increase the load-bearing capacity of steel
C. To provide corrosion resistance to concrete surfaces
D. To protect structural members from heat during a fire, maintaining their
integrity
E. To waterproof building surfaces
Correct Answer: D EXPERT RATIONALE: Spray-applied fireproofing is designed
to insulate structural members — primarily steel — from the intense heat of a fire,
slowing the temperature rise and maintaining structural integrity long enough for
occupants to evacuate and for firefighters to respond.
,2. Which standard is most commonly referenced for the application and
inspection of spray-applied fire-resistive materials (SFRM)?
A. ASTM E84
B. NFPA 13
C. ICC IBC Chapter 17 and ASTM E605
D. ACI 318
E. OSHA 1926.800
Correct Answer: C EXPERT RATIONALE: The International Building Code (IBC)
Chapter 17 governs special inspections, and ASTM E605 is the standard test method
for thickness and density of SFRM, making these the primary references for spray-
applied fireproofing inspection.
3. What does the term "fire-resistance rating" refer to?
A. The temperature at which a material ignites
B. The ability of a material to conduct heat
C. The duration in hours a building element resists fire exposure under
standardized test conditions
D. The melting point of structural steel
E. The combustibility index of a spray material
Correct Answer: C EXPERT RATIONALE: A fire-resistance rating is expressed in
hours and represents how long a structural assembly can withstand fire exposure
as tested under ASTM E119 or equivalent standards before failing structurally or
allowing heat transmission beyond prescribed limits.
4. Which of the following is a Type I SFRM (Spray-Applied Fire-Resistive
Material)?
,A. Cementitious material
B. Intumescent paint
C. Gypsum board
D. Mineral wool blanket
E. Ceramic tile
Correct Answer: A EXPERT RATIONALE: Cementitious materials are classified
as Type I SFRM. They are mixed with water and sprayed onto structural members.
Intumescent coatings are a different category, and gypsum board and mineral wool
are passive fire protection systems but not SFRMs.
5. What is the minimum ambient temperature typically required during the
application of SFRM?
A. 20°F (-6°C)
B. 25°F (-4°C)
C. 40°F (4°C)
D. 50°F (10°C)
E. 60°F (16°C)
Correct Answer: C EXPERT RATIONALE: Most SFRM manufacturers and
applicable standards require a minimum ambient temperature of 40°F (4°C) during
application and until the material has cured, to prevent freezing and ensure proper
bonding and hardening.
6. Who is responsible for the special inspection of SFRM during construction?
A. The general contractor
B. The spray applicator
, C. The approved special inspector employed by or contracted through the
owner
D. The local fire marshal
E. The architect of record
Correct Answer: C EXPERT RATIONALE: Per IBC Section 1705, special
inspections must be performed by an approved special inspector retained by the
owner (or the owner's agent). This ensures independence from the contractor
performing the work.
7. What tool is used to measure the thickness of SFRM after application?
A. Vernier caliper
B. Torque wrench
C. Pin-type thickness gauge (depth probe)
D. Steel ruler
E. Digital micrometer
Correct Answer: C EXPERT RATIONALE: A pin-type thickness gauge (also called
a depth probe or needlepoint gauge) is the standard tool used to measure SFRM
thickness per ASTM E605. The pin is inserted through the material until it contacts
the substrate.
8. How frequently should thickness tests be conducted on SFRM applied to
floor and roof assemblies?
A. Once per floor
B. Every 500 square feet
C. One test per 1,000 square feet of spray area per floor
D. Every 2,000 square feet
