CFI QUESTIONS WITH CORRECT
ANSWERS.
Fire Spread Analysis ANS - The process of IDing fire patterns relating to the movement of fire from one
place to anothern & the sequence in which the patterns were produced to trace the fire back to the
origin
Heat Capicity ANS - A Measure of the energy required to raise the temp of an object one degree of unit
measured J/Kg/K
Intent ANS - Needed to show proof if a crime & refers to the state of mind that exist at the time a
person acts or fails to act
Platform frame construction ANS - The most common construction method currently used for
residential and lightweight commercial construction
Wild land V shaped Pattern ANS - Horizontal ground surface burn pattern generated by fire spread
HRR heat release rate ANS - The energy being released by the individual fuels being consumed
measured in Watts or Kilowatts
Investigator 1033 shall minimum up to date of the following ANS - Fire science chemistry.
Thermodynamics. Thermometer. Fire dynamics. Explosion. Computer fire modeling. Fire analysis. Fire
investigation method. Fire technology. Hazmat. Failure analysis
Natural gas weight ANS - .96 - .98 less then air rises
Propane weight ANS - 1.5 - 2.0 greater then air falls
Heat flux ANS - The measurement of the rate of heat transfer to a surface
, Aluminum conductivity ANS - Lower than copper
Motion ANS - Request for the court to take action
Thermal inertia ANS - Heat x density x thermal conductivity
-key factor in considering the materials reaction to heating & ease of ignition
Evidence containers ANS - Metal cans
Jars
Special evidence bags
Common plastic bags
Trapped porous materials ANS - (Concrete) floors-use-
Non self rising flower
Auto ignition temp
Gas
Diesel
Motor oil ANS - 495 - 536
489 - 500
644 - 680
flashover ANS - Compartment - radiant heat reaches ignition temp impinges on other combustible items
within the room producing fire gases
A = V/ohm ANS - Resistance & voltage can be measured - the amperage can be calculated
Gas flash point ANS - 49 - 40
