FLORIDA FIRE INVESTIGATOR EXAM
QUESTIONS AND ANSWERS 100%
CORRECT
Ordinary Construction - ANSWERBuilding in which the exterior and load bearing
interior walls are non-combustible, or limited combustion, with a minimum one hour
resistive rating
Open Flame - ANSWEROpen flame of a match or lighter is the most effective and
most common ignition source for fires
Bernoulli Effect - ANSWERWind 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 - ANSWER2000
Emergency Response Book (colors)
Burn Patterns or Char Depth - ANSWERThe most universally accepted means to
follow a fire's path
Fire Department - ANSWERResponsible for maintaining custody and control of the
scene until the investigation complete
Burn Patterns because their universal applicability - ANSWERCornerstone of All Fire
Investigations
Changes in level indicate points of ventilation - ANSWERHeight 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 - ANSWERChar rate of wood
The Higher the intensity of the flame the faster the charring and the deeper the
resulting char. - ANSWERWhat effects char rate
Char Depth - ANSWERDepth to which pyrolysis action if fire has converted an
organic material to its volatile fractions and charcoal
Chip Board - ANSWERWood chips that are glued together and formed into flat
sheets
, Alligatoring - ANSWERLarge shiny blisters of char that indicate a fast moving fire
(Only a Rule of thumb)
Spalling - ANSWERThe chipping or crumbling of concrete or masonry surface.
Flammable Liquid - ANSWERLiquids which have a flash point <100 degrees F
Combustible Liquid - ANSWERLiquid which have a flash point >100 degrees F
Alloy - ANSWERHas a melting point below that of either original metal
Fuel Injection systems - ANSWERhave 25- 100psi
Static Electricity - ANSWERWhen it discharges contributes to fire and explosion
hazards in many phases of industry.
Wool - ANSWERNatural Fiber, Minimal Fire Hazard
Cotton - ANSWERMost Flammable natural common fiber. Considered most
hazardous
Establishing a Preliminary Perimeter - ANSWERThe 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 - ANSWERAsphyxiation, rather than fire explosion
CO poisoning - ANSWERrequires 20% saturation to produce serious side effects
40%= Unconsciousness is expected
50% or greater =Death
Static Load - ANSWERLoads which are applied slowly ad remain constant. Ex A
heavy safe is a Live and Static Load.
Dead Load - ANSWERThe weight of the building itself and any equipment
permanently attached to it.
Live Load - ANSWERA Load that moves or is not constant [Water in a Tank]
Fuel Load - ANSWERAll combustibles in a fire area, whether part of the structure,
finish, or furnishings.
Incendiary Fires - ANSWERA deliberately set fire
Blue Flame of Natural Gas - ANSWERReflects 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 - ANSWERShould be considered suspicious
