Fire & Smoke Restoration Technician (IICRC FSRT) Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary cause of smoke damage in a fire?

a) Water used in firefighting

b) Soot deposition

c) Combustion byproducts

d) High humidity

Rationale: Combustion produces smoke and soot, which are the main

causes of smoke damage.

• Which type of smoke is typically oily and difficult to clean?

a) Protein-based smoke

b) Dry smoke 1 / 4

c) Wet smoke

d) Fuel oil smoke

Rationale: Wet smoke is generated from low-temperature,

smoldering fires and tends to be oily and sticky.

• Which is the first step in fire damage restoration?

a) Repainting walls

b) Carpet cleaning

c) Assessing the damage and safety

d) Installing new HVAC filters

Rationale: Safety assessment and evaluation are critical before

starting any restoration work.

4. The “flashover” in a fire refers to:

a) The initial spark

b) When all combustible surfaces ignite simultaneously

c) Fire suppression with water

d) Smoke ventilation

Rationale: Flashover occurs when all combustible materials in a

space ignite nearly simultaneously, a critical fire behavior concept.

• Which PPE is essential during smoke damage restoration?

a) Gloves only

b) Hard hat only

c) Respirator, gloves, and protective clothing

d) Safety shoes only 2 / 4

Rationale: Smoke and soot contain harmful particulates and

chemicals, requiring full PPE.

• Which cleaning method is most effective for soot on non-porous

surfaces?

a) Dry brushing

b) Wet cleaning with appropriate detergents

c) Vacuuming only

d) Sandblasting

Rationale: Wet cleaning dissolves and removes soot effectively from

non-porous surfaces.

• What type of smoke is typically produced by high-temperature fires?

a) Dry smoke

b) Wet smoke

c) Protein smoke

d) Fuel oil smoke

Rationale: High-temperature, fast-burning fires produce dry smoke

that is powdery and less oily.

• Which factor influences smoke behavior and damage?

a) Color of walls

b) Temperature, humidity, and air movement

c) Brand of fire extinguisher

d) Type of furniture 3 / 4

Rationale: Smoke spreads according to airflow, temperature, and

moisture conditions.

• What is the main purpose of thermal fogging in smoke restoration?

a) Painting surfaces

b) Carpet cleaning

c) Odor neutralization

d) Fire suppression

Rationale: Thermal fogging uses heated deodorizing agents to

penetrate and neutralize smoke odors.

10. Soot that is heavy and greasy is typically from:

a) Dry wood fires

b) Oil or synthetic materials

c) Paper fires

d) Protein fires

Rationale: Greasy soot is generated by synthetic materials and oils

during combustion.

• Which type of smoke tends to discolor paint and varnishes?

a) Dry smoke

b) Fuel oil smoke

c) Protein-based smoke

d) Water vapor

Rationale: Protein smoke is a low-temperature combustion product

that easily causes discoloration.
