Illinois Fireproofing Installer Certification Examination Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf (Fireproofing Materials, Application Procedures, Codes, Safety, Inspection Requirements)

• What is the primary purpose of applying spray-applied fire-resistive

materials (SFRM)?

• Improve building aesthetics
• Increase structural fire resistance
• Prevent corrosion
• Reduce sound transmission

Rationale: SFRM protects structural elements by delaying heat penetration

during a fire. 1 / 4

• Which type of fireproofing is commonly applied to steel structural

members in commercial buildings?

• Intumescent paint only
• Cement plaster
• Spray-applied fire-resistive material
• Gypsum board

Rationale: SFRM is the most widely used method for steel protection in

large structures.

3. Intumescent coatings expand when exposed to:

• Cold temperatures
• Heat
• Moisture
• UV light

Rationale: Intumescent materials swell from heat, forming an insulating

char.

• Which of the following best describes “bond strength” in fireproofing?
• Resistance to weathering
• Ability to expand under heat
• Adhesion of fireproofing to the substrate
• Surface hardness

Rationale: Bond strength measures how well fireproofing adheres to

structural surfaces. 2 / 4

5. Before applying SFRM, the substrate surface must be:

• Painted
• Wet
• Clean and free of contaminants
• Primed with latex

Rationale: Dirt, oil, rust, or paint reduce adhesion and performance.

6. The required fire-resistance rating for structural steel is determined by:

• Contractor preference
• Owner’s request
• Material cost
• Building codes and design documents

Rationale: Fire ratings come from codes and the project’s fire protection

design.

• Which environmental condition can negatively affect SFRM application?
• High humidity
• Extreme cold
• Wind
• All of the above

Rationale: All environmental factors can disrupt adhesion and curing.

8. The minimum ambient temperature for applying most SFRMs is:

A. 10°F

B. 20°F 3 / 4

C. 40°F

D. 70°F

Rationale: Most products require at least 40°F for proper bonding and

curing.

9. Fireproofing thickness is typically measured using a:

• Laser level
• Metal ruler
• Depth micrometer
• Pin depth gauge

Rationale: Pin depth gauges are the standard tool for thickness

measurements.

10. The term “intumescent” means:

• Adhesive
• Expands with heat
• Hardens under pressure
• Reacts to moisture

Rationale: Intumescent coatings expand under heat to provide insulation.

• Which type of fireproofing is most commonly used in exposed

architectural spaces?

• Cementitious SFRM
• Intumescent coatings
