VERSIONS| WITH ACTUAL CORRECT
QUESTIONS AND VERIFIED DETAILED
RATIONALES ANSWERS 2024 (NEWEST)
ALREADY GRADED A+
The reasoning process of moving from generalizations to particular assertion
(*"Reduce to Deduce"
*Test hypothesis ("deduce")
*Test based on known facts
*More confident assertion than induction)
Deductive Reasoning
Type of evidence consisting of tangible items
*as opposed to Testimonial Evidence or Documentary (written) Evidence
Demonstrative Evidence
A burn pattern analysis that is MORE useful for evaluating fire spread, rather than length or intensity of
burning
Depth of Char
All voltages are _________________, which means that a battery or DC generator creates a potential
difference that can force charge through a wire
Differential
The ordinary sustained burning mode in most fires
Diffusion Flame Burning
By taking these two steps, an investigator can obtain the manufacturer's name, model & serial numbers,
manufacture date, and any warnings on an appliance, determined to be in the area of fire origin
Document and Carefully Move
What type of evidence is an investigator's report?
Documentary Evidence
,2|Page
A key method used by investigators when an appliance is determined to be in the area of origin,
particularly the positioning of all controls and components.
Documentation
The standards that gas cylinders must conform to
(Dept. of Transportation)
DOT Standards
Types of fuses that have one element for overloads and another element for short circuits
Dual Element Fuses
A particular type of an explosion that does NOT often result in pronounced seats of explosion
Dust Explosion
An explosion that most often occurs in confined areas of relatively wide dispersal, where combustible
dust can accumulate in sufficient quantity to support a propagating reaction.
Dust Explosion
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.
Engine Oil Analysis
The fire scene itself needs to be considered as WHAT?
Evidence
The process of photographing an item, then collecting, tagging and putting it in a log
Evidence Collection
The importance of this fire investigative practice is no different in wildfire investigations, compared to
structural fires.
Evidence Collection and Documentation
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
Evidence Custodian
The justification used to enter a property in order to extinguish a fire
Exigent Circumstances
Also known as "Conclusions"
Final Hypothesis
,3|Page
A team comprised of a homicide detective, medical examiner, and fire investigator
Fire Death Team
A type of analysis used to predict fire phenomena and characteristics of the environment
Fire Dynamics Analysis
Observable or measurable changes in or on a material as the result of a fire
Fire Effects
Once a fuel is ignited in a motor vehicle, any additional fuels contained in the vehicle have significant
effect on WHAT fire factor?
Fire Growth Rate
In a wildland fire, this fire characterisic is indicated by the degree of damage to the wildland fuel
Fire Intensity
This investigative determination is based on witness information, fire patterns, arc mapping, and fire
dynamics
Fire Origin
The fifth and sixth amendments DO NOT answer questions regarding constitutional protections in
relation to WHAT fire investigation aspect?
(4th amendment issue)
Fire Scene Access
Recreating pre-fire positions of contents
Fire Scene Reconstruction
This type of door must be used when installed in a fire-rated wall.
Fire-rated Door
This is the typical extent of thermal injuries sustained from an explosion flame front, due to the very
short duration.
First or Second Degree Burns
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
Flame Spread Rating
, 4|Page
This type of fuel can only be ignited by a spark or pilot flame over specific ranges of gas concentration
Flammable Gases
A liquid with a flash point below 100*F
Flammable Liquid
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.
Flash Point
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
Flashover
These construction features are tested for fire spread from below, but NOT from above
Floor Assemblies
The two mechanisms of convection heat transfer
Forced and Natural
This law allows fire investigators to gain information, in most states
Freedom of Information Act
Any substance that can undergo combustion
Fuel
Total quantity of combustible contents of a building, space, or fire area (expressed in heat units or the
equivalent weight in wood)
Fuel load
This system in a vehicle has the following sequence of components:
Fuel tank, fuel pump, fuel injector/carburetor, manifold, and cylinders.
