Florida Fire Investigator Exam
ACCURATE 100%
Ordinary Construction - ANSWER 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 - ANSWER Open flame of a match or lighter is the most effective and most
common ignition source for fires
Bernoulli Effect - ANSWER 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 - ANSWER 2000
Emergency Response Book (colors)
Static Load - ANSWER Loads which are applied slowly ad remain constant. Ex A heavy
safe is a Live and Static Load.
Dead Load - ANSWER The weight of the building itself and any equipment permanently
attached to it.
Live Load - ANSWER A Load that moves or is not constant [Water in a Tank]
Fuel Load - ANSWER All combustibles in a fire area, whether part of the structure,
finish, or furnishings.
Incendiary Fires - ANSWER A deliberately set fire
Burn Patterns or Char Depth - ANSWER The most universally accepted means to follow
a fire's path
Fire Department - ANSWER Responsible for maintaining custody and control of the
scene until the investigation complete
Burn Patterns because their universal applicability - ANSWER Cornerstone of All Fire
Investigations
Changes in level indicate points of ventilation - ANSWER 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 - ANSWER Char rate of wood
The Higher the intensity of the flame the faster the charring and the deeper the resulting
char. - ANSWER What effects char rate
Char Depth - ANSWER Depth to which pyrolysis action if fire has converted an organic
material to its volatile fractions and charcoal
Chip Board - ANSWER Wood chips that are glued together and formed into flat sheets
Alligatoring - ANSWER Large shiny blisters of char that indicate a fast moving fire (Only
a Rule of thumb)
Class II Liquid - ANSWER Over 100 degrees F
Copper - ANSWER Has the highest melting point 1981 degrees F
Aluminum - ANSWER Melting point 1220 Degrees F
Exothermic Reaction - ANSWER The rate will get really double with each 10 degrees
Centigrade (18 degrees F) rise in temperature
Head of a Match - ANSWER Contains an oxidizer and a fuel such as sulfur and will
ignite struck against a strip containing red phosphorous
When a Gas Appliance starts a fire - ANSWER The pattern will often shoe the origin to
be behind, around, or over the appliance. The arsonist will often set a fire close to a gas
appliance but the pattern will often be below the appliance or in regions where gas
could not reach.
Crowning Fire - ANSWER A fire that may flash across and upward through the top of
the trees and leaves.
Wire colors - ANSWER Green= Ground
Black= Hot
White = Neutral
Deflagration - ANSWER A very rapid oxidation with the evolution of heat and lights as
well as the generation of a very low intensity pressure wave but can cause serious
structural damage to a building
