IICRC FSRT Fire and Smoke Restoration
Technology Actual Exam Newest With
Complete Questions And Correct
Detailed Answers
Question 1
What are the three basic components required for combustion (fire)?
A. Carbon, hydrogen, oxygen
B. Fuel, heat, oxygen
C. Wood, paper, plastic
D. Smoke, heat, light
Answer: B. Fuel, heat, oxygen
Rationale: The three essential elements required for a fire to occur are fuel
(combustible material), heat (ignition source), and oxygen (oxidizing agent). This is
known as the fire triangle .
Question 2
A major factor in determining the temperature of the fire is the amount of
__________ available.
A. Fuel
B. Oxygen
C. Carbon monoxide
D. Hydrogen
,Answer: B. Oxygen
Rationale: The amount of oxygen present during combustion directly influences
fire temperature. More oxygen typically supports higher temperatures and more
complete combustion .
Question 3
The amount of smoke residue within a given area is _________________ with lack
of oxygen.
A. Decreased
B. Increased
C. Unchanged
D. Eliminated
Answer: B. Increased
Rationale: When oxygen is limited, combustion becomes incomplete, resulting in
the production of more smoke residue and soot particles .
Question 4
The severity of soot contamination increases with a ________ of oxygen and
decreases when a _________ _______ of oxygen is present during the fire.
A. lack, greater quantity
B. abundance, lesser amount
C. presence, complete absence
D. increase, similar amount
,Answer: A. lack, greater quantity
Rationale: Soot production is highest when oxygen is limited (incomplete
combustion) and decreases when sufficient oxygen allows for more complete
combustion .
Question 5
A by-product of incomplete combustion classified as carcinogenic is:
A. Carbon dioxide
B. Water vapor
C. Polycyclic Aromatic Hydrocarbons (PAH)
D. Nitrogen oxide
Answer: C. Polycyclic Aromatic Hydrocarbons (PAH)
Rationale: PAHs are a class of chemicals that occur naturally in coal, crude oil, and
gasoline. They are produced as by-products of incomplete combustion and many
are classified as carcinogens .
Question 6
Both PAH and soot particles have been reported to be ___________ to humans.
A. Beneficial
B. Harmless
C. Carcinogenic
D. Nutritious
, Answer: C. Carcinogenic
Rationale: Research has shown that both Polycyclic Aromatic Hydrocarbons (PAH)
and soot particles contain carcinogenic compounds that pose health risks to
humans .
Question 7
Temperature creates __________ forcing soot residue into inaccessible spaces.
A. Pressure
B. Vacuum
C. Condensation
D. Evaporation
Answer: A. Pressure
Rationale: The heat from a fire creates pressure differentials that can force smoke
and soot residues into cavities, wall voids, and other inaccessible areas
throughout the structure .
Question 8
Soot residues gravitate or migrate to:
A. Warmer surfaces
B. Cooler surfaces
C. Ceilings only
D. Floors only
