Question 1

Two identical rooms experience fires with the same fuel load. Room A is sealed with limited ventilation; Room B has an open window feeding it air. Which factor is MOST responsible for Room B reaching a higher temperature?

  1. A lower flash point of the fuel inside Room B
  2. The larger volume of incomplete-combustion products in Room B
  3. The greater supply of oxygen feeding the fire in Room B
  4. The drier, more powdery smoke residue produced in Room B
Show answer & explanation

Correct answer: C - The greater supply of oxygen feeding the fire in Room B

Question 2

A technician inspects a structure after a slow, smoldering, oxygen-starved fire. The residue on the walls is sticky, smeary, and pungent, and it tends to smear when wiped. This residue is BEST classified as:

  1. Wet smoke residue
  2. Dry smoke residue
  3. Protein residue
  4. Fuel oil (puff-back) residue
Show answer & explanation

Correct answer: A - Wet smoke residue

Question 3

A homeowner reports a strong, lingering odor in the kitchen after a stovetop grease fire, but the technician can see almost no visible soot on the surfaces. The MOST likely residue present is:

  1. Dry smoke residue, which is fine and powdery
  2. Synthetic residue from melted and burned plastics
  3. Fuel oil residue from a heating-system puff-back
  4. Protein residue, which is greasy and nearly invisible
Show answer & explanation

Correct answer: D - Protein residue, which is greasy and nearly invisible

Question 4

A technician begins cleaning soot from a non-porous painted wall. To avoid driving residue deeper into the surface and causing smearing, the FIRST step should be to:

  1. Apply a heated alkaline cleaning solution with a wet sponge
  2. Use dry methods to remove loose surface soot
  3. Rinse the wall with low-pressure water to loosen residue
  4. Seal the surface with pigmented shellac before cleaning
Show answer & explanation

Correct answer: B - Use dry methods to remove loose surface soot

Question 5

Soot residue from a typical structure fire is generally acidic. To neutralize the residue and clean effectively, a technician should usually select a cleaning agent that is:

  1. Strongly acidic, to chemically match the residue
  2. Precisely neutral, at a measured pH of 7
  3. Alkaline, to shift the residue toward neutral
  4. A nonpolar organic solvent in all situations
Show answer & explanation

Correct answer: C - Alkaline, to shift the residue toward neutral

Question 6

A dry chemical sponge ('soot sponge') removes smoke residue from a surface primarily through which process?

  1. Adsorption, as residue adheres to the sponge
  2. Emulsification of the soot within the sponge
  3. Saponification of the oily soot residue
  4. Dissolution of the residue into a solvent
Show answer & explanation

Correct answer: A - Adsorption, as residue adheres to the sponge

Question 7

The principles of effective odor control include all of the following EXCEPT:

  1. Removing the source of the odor
  2. Cleaning residue from the affected surfaces
  3. Recreating the conditions under which the odor penetrated
  4. Applying a masking agent as the permanent fix
Show answer & explanation

Correct answer: D - Applying a masking agent as the permanent fix

Question 8

A technician must deodorize an apartment where the occupants and their pet cannot relocate during treatment. Which approach is appropriate for this OCCUPIED space?

  1. An ozone generator, since ozone later reverts to oxygen
  2. A hydroxyl generator, which is generally safe around occupants
  3. Thermal fogging, since the fog dissipates fairly quickly
  4. An ozone generator set to a reduced output level
Show answer & explanation

Correct answer: B - A hydroxyl generator, which is generally safe around occupants

Question 9

When evaluating respiratory hazards on a fire loss, a technician should recognize that polycyclic aromatic hydrocarbons (PAHs) are:

  1. Inert soot pigments that only affect surface appearance
  2. Generated only while open flames are actively burning
  3. Carcinogens that can also be re-released during demolition
  4. Created exclusively by the burning of synthetic plastics
Show answer & explanation

Correct answer: C - Carcinogens that can also be re-released during demolition

Question 10

Immediately after arriving at a fire loss, a restoration contractor's PRIMARY objective during the mitigation phase is to:

  1. Prevent further damage to the structure and contents
  2. Restore all cosmetic finishes to their pre-loss state
  3. Complete a full inventory of the non-salvageable items
  4. Apply deodorizing fog throughout the entire structure
Show answer & explanation

Correct answer: A - Prevent further damage to the structure and contents
