1. A California fireproofing contractor is preparing to apply a
cementitious spray-applied fire-resistive material (SFRM) to structural
steel columns in a multi-story commercial building. Before application
begins, which of the following conditions is MOST critical to verify in
order to ensure proper adhesion and compliance with fire-resistance
design specifications?
A. The structural steel has been coated with a decorative acrylic finish to
improve appearance
B. The steel surface is free of oil, loose rust, scale, and incompatible primers
that may interfere with adhesion
C. The ambient temperature inside the building exceeds 100°F to accelerate
curing
,D. The structural steel has already been enclosed with gypsum wallboard
assemblies
B. The steel surface is free of oil, loose rust, scale, and incompatible
primers that may interfere with adhesion
Proper substrate preparation is essential for successful fireproofing
installation because contaminants, rust, or incompatible coatings can
prevent adequate bonding of fire-resistive materials. California building
standards and manufacturer specifications require clean and suitable
surfaces to achieve the tested fire-resistance rating.
2. During inspection of a fireproofing installation in a high-rise structure,
a contractor discovers that the installed thickness of spray-applied
fireproofing is below the specified density and thickness required by
the approved UL design. What is the MOST appropriate corrective
action?
A. Apply paint over the deficient areas to improve fire resistance
B. Leave the material in place because minor deviations are acceptable in all
occupancies
C. Remove or supplement the deficient fireproofing to achieve the required
tested assembly thickness and density
D. Install additional insulation only around electrical conduits
,C. Remove or supplement the deficient fireproofing to achieve the
required tested assembly thickness and density
Fireproofing systems must match the tested assembly design exactly,
including density and thickness. Deficient installations compromise fire
resistance and code compliance, requiring correction to restore the
intended hourly rating and occupant protection.
3. Which of the following BEST describes the primary purpose of
intumescent fireproofing coatings used on structural steel in
commercial construction?
A. To increase steel conductivity during electrical grounding operations
B. To reduce corrosion through waterproof encapsulation only
C. To expand when exposed to heat, forming an insulating char layer that
protects steel from rapid temperature rise
D. To permanently harden concrete during seismic activity
C. To expand when exposed to heat, forming an insulating char layer that
protects steel from rapid temperature rise
Intumescent coatings react to elevated temperatures by swelling into a
thick insulating char layer. This protective barrier delays heat transfer to
structural steel, helping maintain structural integrity during a fire event.
, 4. A fireproofing contractor working in California is reviewing approved
construction documents for a hospital project. The plans specify a
two-hour fire-resistance rating for floor-ceiling assemblies. Which
factor is MOST important when selecting an approved fireproofing
system?
A. The architectural paint color selected for the ceiling finish
B. The fire-resistance testing laboratory listing corresponding to the
specified assembly
C. The HVAC contractor’s preferred duct insulation method
D. The number of windows installed on the building exterior
B. The fire-resistance testing laboratory listing corresponding to the
specified assembly
Fireproofing systems must conform to tested and listed assemblies
published by recognized laboratories such as UL or Intertek. The assembly
listing provides exact construction requirements necessary to achieve the
specified fire-resistance rating.
5. In California commercial construction, which agency or code primarily
governs fire-resistance requirements for building assemblies and
fireproofing systems?
A. California Department of Fish and Wildlife
B. California Building Standards Code, including the California Building Code
