Florida Fire Investigator Exam
2025/2026 100% QUESTIONS AND ALL
CORRECT ANSWERS HIGHLY GRADED A+
Burn Patterns or Char Depth - CORRECT ANSWERS--The most universally accepted
means to follow a fire's path
Fire Department - CORRECT ANSWERS--Responsible for maintaining custody and
control of the scene until the investigation complete
Burn Patterns because their universal applicability - CORRECT ANSWERS--
Cornerstone of All Fire Investigations
Changes in level indicate points of ventilation - CORRECT ANSWERS--Height of
significant levels of heat in a room is revealed by charring, burning, blistering, or
discoloration of paint or wall coverings. It will generally be level that is of uniform height
from the floor when the atmosphere in the room is fairly static.
1 inch for every 45 minutes - CORRECT ANSWERS--Char rate of wood
The Higher the intensity of the flame the faster the charring and the deeper the resulting
char. - CORRECT ANSWERS--What effects char rate
Char Depth - CORRECT ANSWERS--Depth to which pyrolysis action if fire has
converted an organic material to its volatile fractions and charcoal
Chip Board - CORRECT ANSWERS--Wood chips that are glued together and formed
into flat sheets
Alligatoring - CORRECT ANSWERS--Large shiny blisters of char that indicate a fast
moving fire (Only a Rule of thumb)
Spalling - CORRECT ANSWERS--The chipping or crumbling of concrete or masonry
surface.
Flammable Liquid - CORRECT ANSWERS--Liquids which have a flash point <100
degrees F
Combustible Liquid - CORRECT ANSWERS--Liquid which have a flash point >100
degrees F
, Alloy - CORRECT ANSWERS--Has a melting point below that of either original metal
Fuel Injection systems - CORRECT ANSWERS--have 25- 100psi
Static Electricity - CORRECT ANSWERS--When it discharges contributes to fire and
explosion hazards in many phases of industry.
Wool - CORRECT ANSWERS--Natural Fiber, Minimal Fire Hazard
Cotton - CORRECT ANSWERS--Most Flammable natural common fiber. Considered
most hazardous
Establishing a Preliminary Perimeter - CORRECT ANSWERS--The distance from the
apparent seat to the farthest discovered fragment should be multiplied by at least 1.5
Most fire fatalities are a result of - CORRECT ANSWERS--Asphyxiation, rather than fire
explosion
CO poisoning - CORRECT ANSWERS--requires 20% saturation to produce serious
side effects
40%= Unconsciousness is expected
50% or greater =Death
Blue Flame of Natural Gas - CORRECT ANSWERS--Reflects almost complete
conversion of the fuel to CO2 and H20 and generates very little CO (everything working
properly, if producing soot it's producing CO.
Basement Fires - CORRECT ANSWERS--Should be considered suspicious
Cigarettes - CORRECT ANSWERS--Are rather uncommon as the source of ignition for
a successful structure fire, but is a problem of accidental fires from careless
extinguisher.
Fluorine - CORRECT ANSWERS--Most chemically active non-metal
Before beginning the actual search for evidence you should? - CORRECT ANSWERS--
Inspect outside of the building first, examine the exterior of the structure from all sides.
Most common detected delay device in grass and wildland fires - CORRECT
ANSWERS--Matches tied outside of a cigarette
Incendiary ammunition - CORRECT ANSWERS--Usually contains white phosphorous
or similar material with a low ignition temperature
