Florida Fire Investigator Exam Q&A
100% Guaranteed Success | Graded A+
Ordinary Construction - ✔✔Building in which the exterior and load bearing
interior walls are non-combustible, or limited combustion, with a minimum one
hour resistive rating
Open Flame - ✔✔Open flame of a match or lighter is the most effective and
most common ignition source for fires
Bernoulli Effect - ✔✔Wind blowing across a chimney opening, lowering the
pressure at the chimney mouth.
Yellow: Dangerous goods in numerical order
Blue: Dangerous goods by material name
Orange: All safety recommendations.
Green: Table of Initial Isolation and protective action distances - ✔✔2000
Emergency Response Book (colors)
Static Load - ✔✔Loads which are applied slowly ad remain constant. Ex A heavy
safe is a Live and Static Load.
Dead Load - ✔✔The weight of the building itself and any equipment
permanently attached to it.

,Live Load - ✔✔A Load that moves or is not constant [Water in a Tank]
Fuel Load - ✔✔All combustibles in a fire area, whether part of the structure,
finish, or furnishings.
Incendiary Fires - ✔✔A deliberately set fire
Burn Patterns or Char Depth - ✔✔The most universally accepted means to
follow a fire's path
Fire Department - ✔✔Responsible for maintaining custody and control of the
scene until the investigation complete
Burn Patterns because their universal applicability - ✔✔Cornerstone of All Fire
Investigations
Changes in level indicate points of ventilation - ✔✔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 - ✔✔Char rate of wood
The Higher the intensity of the flame the faster the charring and the deeper the
resulting char. - ✔✔What effects char rate

, Char Depth - ✔✔Depth to which pyrolysis action if fire has converted an organic
material to its volatile fractions and charcoal
Chip Board - ✔✔Wood chips that are glued together and formed into flat sheets
Alligatoring - ✔✔Large shiny blisters of char that indicate a fast moving fire
(Only a Rule of thumb)
Spalling - ✔✔The chipping or crumbling of concrete or masonry surface.
Flammable Liquid - ✔✔Liquids which have a flash point <100 degrees F
Combustible Liquid - ✔✔Liquid which have a flash point >100 degrees F
Alloy - ✔✔Has a melting point below that of either original metal
Fuel Injection systems - ✔✔have 25- 100psi
Static Electricity - ✔✔When it discharges contributes to fire and explosion
hazards in many phases of industry.
Wool - ✔✔Natural Fiber, Minimal Fire Hazard
Cotton - ✔✔Most Flammable natural common fiber. Considered most
hazardous
Establishing a Preliminary Perimeter - ✔✔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 - ✔✔Asphyxiation, rather than fire explosion
