The OSFMFRP04 – Intumescent Paint Application Certification E
SECTION ONE – QUESTIONS 1–50
1. What is the primary purpose of intumescent paint on structural steel?
A. To improve corrosion resistance only
B. To provide decorative color finishes
C. To insulate steel during fire exposure
D. To increase steel tensile strength
,🟢 Correct Answer: C. To insulate steel during fire exposure
🔴 Explanation: Intumescent paint expands when exposed to heat, creating an insulating
char layer that delays the temperature rise of structural steel during a fire.
2. Which factor most directly affects the required dry film thickness (DFT) of intumescent
coating?
A. Color of the coating
B. Steel section factor
C. Brand of spray gun
D. Shape of the building
🟢 Correct Answer: B. Steel section factor
🔴 Explanation: The section factor determines how quickly steel heats during a fire,
directly influencing the required coating thickness.
3. What is the first step before applying intumescent coating to steel?
A. Install finish cladding
B. Apply decorative topcoat
C. Verify surface preparation
D. Conduct fire drills
🟢 Correct Answer: C. Verify surface preparation
, 🔴 Explanation: Proper surface preparation ensures adhesion and coating performance,
making it essential before application begins.
4. Which standard is commonly referenced for abrasive blast cleaning of steel?
A. SSPC-SP 10
B. ASTM D3276
C. NFPA 72
D. ISO 834 only
🟢 Correct Answer: A. SSPC-SP 10
🔴 Explanation: SSPC-SP 10 specifies near-white metal blast cleaning requirements
commonly used before intumescent coating application.
5. What happens to intumescent coating during a fire?
A. It melts into liquid form
B. It contracts tightly around steel
C. It evaporates immediately
D. It expands into insulating char
🟢 Correct Answer: D. It expands into insulating char
🔴 Explanation: Intumescent coatings react to heat by expanding and forming a char layer
that protects structural steel from rapid heating.
