1. What is the primary purpose of structural steel fireproofing in a
building?
a. To increase the structural steel's load-carrying capacity
b. To prevent corrosion under all conditions
c. To delay the rise of steel temperature during a fire
d. To eliminate the need for fire alarms
Answer: c. To delay the rise of steel temperature during a fire
Rationale: Fireproofing is designed to insulate structural members and
slow the rate at which they heat during a fire. This provides additional
time before the steel reaches temperatures at which its strength and
stiffness are significantly reduced.
, 2. Which type of fireproofing is commonly applied as a spray directly
to structural steel?
a. Intumescent coating
b. Spray-applied fire-resistive material
c. Ceramic floor tile
d. Galvanized sheet metal
Answer: b. Spray-applied fire-resistive material
Rationale: Spray-applied fire-resistive material (SFRM) is commonly
installed on structural steel using specialized spraying equipment. It
forms an insulating layer that protects the steel from rapid
temperature increase.
3. What happens to structural steel when its temperature becomes
excessively high during a fire?
a. Its strength generally decreases
b. Its density increases significantly
c. Its melting point increases
d. Its structural capacity automatically doubles
Answer: a. Its strength generally decreases
Rationale: Steel loses a significant portion of its yield strength and
stiffness as temperature increases. Fireproofing helps delay this
,temperature rise and therefore helps preserve structural performance
during a fire.
4. Before applying fireproofing, the contractor should primarily
verify that the substrate is:
a. Wet and saturated
b. Clean and suitable for adhesion
c. Covered with loose dust
d. Coated with household paint
Answer: b. Clean and suitable for adhesion
Rationale: Proper surface preparation is essential for adhesion and
performance. Dust, oil, loose scale, incompatible coatings, and other
contaminants can interfere with bonding and may cause the
fireproofing to fail prematurely.
5. Which condition can significantly interfere with the application of
many cementitious fireproofing materials?
a. Excessive moisture or unsuitable environmental conditions
b. Proper ventilation
c. Correct substrate temperature
d. Approved primer
Answer: a. Excessive moisture or unsuitable environmental conditions
, Rationale: Environmental conditions affect mixing, adhesion, curing,
and drying. Contractors must follow the manufacturer's specified
temperature, humidity, ventilation, and substrate requirements.
6. What is the purpose of a fire-resistance rating?
a. To indicate the color of a fireproofing material
b. To indicate the duration a tested assembly can resist specified fire
exposure
c. To determine the cost of labor
d. To identify the manufacturer
Answer: b. To indicate the duration a tested assembly can resist
specified fire exposure
Rationale: Fire-resistance ratings are based on standardized testing or
approved engineering methods. Ratings such as one-hour, two-hour,
or three-hour describe the required fire-resistance performance of an
assembly under specified conditions.
7. Why must the thickness of spray-applied fireproofing be carefully
controlled?
a. Thickness has no relationship to fire resistance
b. The required thickness is related to the tested or approved fire-
resistance design
