Spring Semester February 2026 IICRC Fire & Smoke Restoration
Technician (FSRT) Certification Exam Prep | Fire & Smoke Damage
Restoration Techniques, Odor Removal, Structural Cleaning, Equipment
Operation, Safety Protocols, NGN-Style Practice Questions & Technician
Readiness Guide
,Question 1:
What is the primary cause of smoke damage in a fire restoration scenario?
A) Water damage
B) Incomplete combustion
C) High temperatures
D) Electrical failure
Correct Option: B) Incomplete combustion
Rationale:
Incomplete combustion occurs when there is insufficient oxygen to completely burn
fuel. This results in smoke, soot, and harmful gases. Understanding this is crucial for
effective restoration, as it helps technicians identify and mitigate smoke damage
effectively.
Question 2:
Which of the following types of smoke residues is classified as ‘dry smoke’?
A) High-temperature, fast-burning fires
B) Low-temperature smoldering fires
C) Protein residues
D) Wet smoke
Correct Option: A) High-temperature, fast-burning fires
Rationale:
Dry smoke occurs from high-temperature fires and is characterized by its fine particles.
These residues are easier to clean than those from other types, like wet smoke, making
knowledge of smoke types essential for effective remediation planning.
Question 3:
What is the recommended first step in assessing damage after a fire?
A) Begin clean-up immediately
B) Conduct a thorough inspection
C) Cover damaged areas with tarps
D) Contact insurance companies
Correct Option: B) Conduct a thorough inspection
Rationale:
Conducting a thorough inspection helps identify the extent of fire and smoke damage.
This assessment is crucial for creating an effective restoration plan and ensures that all
damaged areas are properly addressed, thus preventing further issues.
, Question 4:
Which process is utilized to remove smoke odors from materials?
A) Desiccation
B) Thermal fogging
C) Steam cleaning
D) Electrostatically charged wipes
Correct Option: B) Thermal fogging
Rationale:
Thermal fogging is a process that uses heated fog to penetrate materials and neutralize
smoke odors. It is effective because it reaches areas that traditional cleaning methods
cannot. Understanding this technique is vital for restoring indoor air quality post-
restoration.
Question 5:
In fire restoration, what is the purpose of a hydroxyl generator?
A) To moisten dry areas
B) To remove soot from surfaces
C) To neutralize odors and purify air
D) To cool down the affected area
Correct Option: C) To neutralize odors and purify air
Rationale:
Hydroxyl generators create hydroxyl radicals that help eliminate odors and airborne
contaminants. Their use is beneficial in post-fire scenarios to restore healthy indoor air
quality. Knowledge of such technologies enhances a technician's effectiveness in the
restoration process.
Question 6:
Which material is most likely to be damaged by smoke during a fire?
A) Metal
B) Glass
C) Wood
D) Concrete
Correct Option: C) Wood
Rationale:
Wood is porous and can absorb smoke particles, leading to lasting damage and odor.
