IAAI CFI UPDATED COMPREHENSIVE EXAM QUESTIONS
AND SOLUTIONS RATED A+
✔✔Engine Oil Analysis - ✔✔This analysis may be performed to determine the pre-fire
condition of the engine and to establish possible motive for the destruction of the
vehicle.
✔✔Evidence - ✔✔The fire scene itself needs to be considered as WHAT?
✔✔Evidence Collection - ✔✔The process of photographing an item, then collecting,
tagging and putting it in a log
✔✔Evidence Collection and Documentation - ✔✔The importance of this fire
investigative practice is no different in wildfire investigations, compared to structural
fires.
✔✔Evidence Custodian - ✔✔The person at a fire scene who manages various aspects
of the evidence collection process, including an evidence log and evidence bagging,
tagging, preservation and storage
✔✔Exigent Circumstances - ✔✔The justification used to enter a property in order to
extinguish a fire
✔✔Final Hypothesis - ✔✔Also known as "Conclusions"
✔✔Fire Death Team - ✔✔A team comprised of a homicide detective, medical examiner,
and fire investigator
✔✔Fire Dynamics Analysis - ✔✔A type of analysis used to predict fire phenomena and
characteristics of the environment
✔✔Fire Effects - ✔✔Observable or measurable changes in or on a material as the result
of a fire
✔✔Fire Growth Rate - ✔✔Once a fuel is ignited in a motor vehicle, any additional fuels
contained in the vehicle have significant effect on WHAT fire factor?
✔✔Fire Intensity - ✔✔In a wildland fire, this fire characterisic is indicated by the degree
of damage to the wildland fuel
✔✔Fire Origin - ✔✔This investigative determination is based on witness information, fire
patterns, arc mapping, and fire dynamics
,✔✔Fire Scene Access - ✔✔The fifth and sixth amendments DO NOT answer questions
regarding constitutional protections in relation to WHAT fire investigation aspect?
(4th amendment issue)
✔✔Fire Scene Reconstruction - ✔✔Recreating pre-fire positions of contents
✔✔Fire-rated Door - ✔✔This type of door must be used when installed in a fire-rated
wall.
✔✔First or Second Degree Burns - ✔✔This is the typical extent of thermal injuries
sustained from an explosion flame front, due to the very short duration.
✔✔Flame Spread Rating - ✔✔A system used to rate a material's flame spread potential.
*And these are the categories:
Class A: Flame spread index 0-25
Class B: Flame spread index 26-75
Class C: Flame spread index 76-200
✔✔Flammable Gases - ✔✔This type of fuel can only be ignited by a spark or pilot flame
over specific ranges of gas concentration
✔✔Flammable Liquid - ✔✔A liquid with a flash point below 100*F
✔✔Flash point - ✔✔The characteristic of an appropriate mixture of vapor-to-air, which
will cause it to ignite when subjected to an ignition source
✔✔Flash Point - ✔✔A specific fuel characteristic, which will have little or no significance
when the fuel is released in a spray form.
✔✔Flashover - ✔✔In this phenomenon, the radiant ignition of exposed combustible
materials is key
✔✔Flashover - ✔✔This phenomenon will occur in a compartment with a low ceiling and
fire on the floor, before the same fire in a room with high ceilings
✔✔Flashover - ✔✔This fire phenomenon is not really a consideration for wildfires
✔✔Floor Assemblies - ✔✔These construction features are tested for fire spread from
below, but NOT from above
✔✔Forced and Natural - ✔✔The two mechanisms of convection heat transfer
, ✔✔Freedom of Information Act - ✔✔This law allows fire investigators to gain
information, in most states
✔✔Fuel - ✔✔Any substance that can undergo combustion
✔✔Fuel load - ✔✔Total quantity of combustible contents of a building, space, or fire
area (expressed in heat units or the equivalent weight in wood)
✔✔Fuel System - ✔✔This system in a vehicle has the following sequence of
components:
Fuel tank, fuel pump, fuel injector/carburetor, manifold, and cylinders.
✔✔Fuel-controlled Burning - ✔✔Type of burning that occurs in the early stages of a
compartment fire
✔✔Remote Area - ✔✔The location where firefighters should re-fuel all gas-powered
equipment
(away from the fire scene)
✔✔Government Institute - ✔✔NFPA is not this type of institute
✔✔Guide - ✔✔NFPA 921 is this type of document
✔✔Guidelines - ✔✔The information presented in NFPA 921 establishes WHAT?
✔✔Hazards - ✔✔Biological, chemical, physical, and radiological are examples of this
concept that fire investigators should be aware of when investigating a fire scene
✔✔Header - ✔✔The first cutting unit on a combine
✔✔Heat flux - ✔✔The measure of the rate of heat transfer to a surface
✔✔Heat of Combustion - ✔✔The amount of heat released during complete combustion,
which is considered a constant for a specific fuel
(Generally considered a material property and therefore a constant for a specific fuel)
✔✔Heat of Ignition - ✔✔The heat energy that brings about ignition
(divided into two parts: (a) equipment involved in ignition and (b) form of heat of ignition)
✔✔Heat Release Rate - ✔✔The fire characteristic that most affects fire growth during
the pre-flashover phase of a fire
