IICRC FSRT Exam Study Guide Fire and Smoke
Restoration Technician Exam Practice
Questions & Answers
(Verified Answers)
1. What are the three basic components of a fire?
A. Fuel, Heat, Water
B. Fuel, Heat, Oxygen
C. Smoke, Heat, Oxygen
D. Fuel, Carbon, Nitrogen
Answer B. Fuel, Heat, Oxygen
Rationale: The classic "fire triangle" consists of fuel, heat, and
oxygen. Removing any one of these elements will extinguish the
fire.
2. Toxic materials are released into the air during which
processes?
A. Cleaning and deodorizing
B. Inspection and testing
C. Demolition and reconstruction

,D. Packing and storage
Answer C. Demolition and reconstruction
Rationale: Demolition and reconstruction disturb contaminated
materials, releasing harmful particulates, VOCs, and other toxins
into the air.
3. When working in areas with loose soot residue, technicians
should:
A. Rely only on gloves for protection
B. Utilize appropriate engineering controls, PPE, and AFDs
C. Avoid using air movers
D. Skip air filtration to prevent spreading soot
Answer B. Utilize appropriate engineering controls, PPE, and AFDs
Rationale: Loose soot poses inhalation and contamination
hazards, so engineering controls, personal protective equipment,
and air filtration devices (AFDs) are required.
4. What is the average size of a smoke particulate?

,A. 0.001 – 0.01 microns
B. 0.1 – 4 microns
C. 10 – 50 microns
D. 100 – 500 microns
Answer B. 0.1 – 4 microns
Rationale: Smoke particulates are extremely small (0.1–4
microns), enabling them to penetrate crevices, HVAC systems,
and porous materials.
5. Smoke residue is commonly comprised of:
A. Salt and calcium
B. Iron and copper
C. Carbon and oxides of nitrogen
D. Sulfur and lead
Answer C. Carbon and oxides of nitrogen
Rationale: Combustion produces carbon (soot) and oxides of
nitrogen, along with other compounds depending on what has
burned.
