IAAI CFI UPDATED TEST PAPER QUESTIONS AND
SOLUTIONS RATED A+
✔✔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
,✔✔Heat transfer - ✔✔The transport of heat energy from one point to another point,
caused by temperature difference between those points
✔✔Heat transfer - ✔✔The fire phenomenon responsible for much of the physical
evidence used by fire investigators
✔✔High-Order Damage - ✔✔The shattering type of explosion damage
✔✔H.I.N. - ✔✔The type of number an investigator should look for during a boat fire
investigation
✔✔Hot Surfaces - ✔✔This vehicle component will NOT usually ignite gasoline
✔✔Human Body Fat - ✔✔Component of the human body that will act as a fuel and
sustain a flame
✔✔Hypergolic Material - ✔✔Any substance that will spontaneously ignite or explode
upon exposure to an oxidizer.
✔✔Hypergolic Materials - ✔✔Materials that can react with each other
✔✔Ignitable Liquid - ✔✔A type of material that, when trapped in a concrete floor, can be
recovered by using lime, diatomaceous earth, or non-self-rising flour.
✔✔Ignition by Electrical Energy - ✔✔Ignition that involves transferring sufficient heat to
a fuel by passage of electrical current to ignite material that is closeby
✔✔Ignition Temperature - ✔✔The minimum temperature needed to heat a fuel so as to
ignite and begin self-sustained combustion
✔✔Incandescent Light Bulbs - ✔✔An item that tends to "pull" toward the heat source
(*if over 25 watts)
✔✔Incendiary Fire - ✔✔A category of fire that is strongly indicated by the confirmation
of multiple fires
✔✔Incendiary Fire - ✔✔A category of fire that is associated with multiple fires and
trailers
✔✔Incident Scene Commander - ✔✔This person can grant permission for a fire
investigator to enter a scene before the fire is completely extinguished
, ✔✔Inductive Reasoning - ✔✔The reasoning process of moving from specific
observation to broader generalizations
(*Induction is to "increase"
*Develop hypothesis ("induce")
*More uncertain than deduction
*Based on empirical data, training, and experience)
✔✔Interested Party - ✔✔Any person, entity, or organization with obligations or whose
rights or interest might be affected by the investigation of a specific incident
✔✔Interviews - ✔✔(1) Trust, (2) Caution, and (3) Distrust are three types of what?
✔✔Inverted Cone Pattern - ✔✔This fire pattern is often caused by a natural gas leak
✔✔Inverted Cone Patterns - ✔✔Fire patterns commonly created when a vertical flame
plume does not reach the ceiling
✔✔Team Leader Committee - ✔✔In what group is one representative selected from
each investigative party?
✔✔Irregular Pattern - ✔✔A certain pattern that is not necessarily an indicator of the
presence of an ignitable liquid
✔✔Job Performance Requirement - ✔✔A professional description that (1) describes the
specific job task, (2) lists items necessary to complete the task, and (3) describes
measurable outcomes and evaluations for the task
✔✔Joint Investigations - ✔✔These can occur simultaneously and involve separate and
independent examinations through which each party may develop an independent
hypothesis
✔✔Kerosene - ✔✔Which of these fuels has the lowest ignition temperature: kerosene,
gasoline, methane, or propane?
✔✔Kinetic Energy - ✔✔The type of energy that is converted suddenly from potential
energy during an explosion, with the production and release of gases under pressure.
✔✔Laboratory Analysis - ✔✔This entity must confirm any sample obtained by canine
alert, to be considered valid
✔✔Lack of Stability - ✔✔One of the most dangerous situations an investigator may
encounter when examining a boat afloat after a fire
