FIRE AND SMOKE RESTORATION 2026
Exam Questions and Verified Answers | Complete High-Yield Certification
Study Guide
1. What is the primary industry standard governing fire and smoke
restoration practices in the United States?
A. OSHA 29 CFR 1910
B. EPA 40 CFR 61
C. NFPA 921
D. IICRC S700
E. ANSI Z87.1
Correct Answer: D. IICRC S700 EXPERT RATIONALE: The IICRC S700 Standard
for Professional Fire and Smoke Damage Restoration is the primary reference document
that defines procedures, terminology, and best practices for fire and smoke restoration
professionals.
,2. Which type of smoke residue is typically produced by low-temperature,
smoldering fires with incomplete combustion?
A. Dry smoke residue
B. Wet smoke residue
C. Protein smoke residue
D. Fuel oil soot residue
E. High-temperature soot
Correct Answer: B. Wet smoke residue EXPERT RATIONALE: Wet smoke
residue results from low-heat, smoldering fires. It is sticky, smeary, has a strong pungent
odor, and is more difficult to clean than dry smoke residue.
3. Protein smoke residue is MOST commonly produced by the burning of
which of the following?
A. Synthetic plastics
B. Natural wood
C. Meat and organic food materials
D. Petroleum-based products
E. Cotton fabrics
Correct Answer: C. Meat and organic food materials EXPERT RATIONALE:
Protein fires result from burning food — especially meat. The residue is nearly invisible
but has a powerful, pungent odor and can discolor paints and varnishes.
4. Which type of fire residue is typically dry, powdery, and easier to vacuum or
brush off surfaces?
A. Dry smoke residue
B. Wet smoke residue
,C. Protein smoke residue
D. Fuel oil soot
E. Synthetic residue
Correct Answer: A. Dry smoke residue EXPERT RATIONALE: Dry smoke
residue results from fast-burning, high-temperature fires. It is dry, powdery, non-smeary,
and relatively easier to clean compared to wet or protein smoke residues.
5. What term describes the discoloration of surfaces caused by smoke
traveling through air gaps and settling in wall cavities?
A. Thermal tracking
B. Smoke webs
C. Ghost marks
D. Soot channeling
E. Carbon streaking
Correct Answer: B. Smoke webs EXPERT RATIONALE: Smoke webs (also
called ghosting or thermal tracking) are dark marks on walls and ceilings caused by
airborne particles settling along air currents, particularly around HVAC registers and air
gaps.
6. During a fire restoration inspection, "thermal tracking" refers to which
phenomenon?
A. Heat damage to structural beams
B. Dark sooting patterns following air currents along walls and ceilings
C. The spread of flames through ventilation systems
D. Temperature gradients during a structure fire
E. Monitoring heat levels during restoration
, Correct Answer: B. Dark sooting patterns following air currents along walls
and ceilings EXPERT RATIONALE: Thermal tracking occurs when smoke particles
follow convective air currents and deposit on cooler surfaces, producing visible dark
streaks or patterns on walls and ceilings.
7. Which of the following BEST describes the purpose of pre-cleaning in fire
restoration?
A. To apply deodorizing agents before assessment
B. To remove loose soot and debris before applying cleaning agents
C. To seal odors before reconstruction begins
D. To document damage for insurance purposes
E. To test surfaces for chemical compatibility
Correct Answer: B. To remove loose soot and debris before applying
cleaning agents EXPERT RATIONALE: Pre-cleaning removes loose soot and surface
debris to prevent smearing and further contamination when wet cleaning agents are
applied, improving the effectiveness of subsequent cleaning steps.
8. What is the FIRST step a restoration technician should take upon arriving at
a fire-damaged property?
A. Begin removing smoke-damaged contents
B. Apply deodorizing agents immediately
C. Conduct a safety assessment of the structure
D. Set up air scrubbers
E. Contact the insurance adjuster
Correct Answer: C. Conduct a safety assessment of the structure EXPERT
RATIONALE: Safety is always the first priority. The technician must assess structural
