AND CORRECT ANSWERS| A+ GRADE
VERIFIED ANSWERS
This feature distinguishes the heat-sensitive bulbs of
sprinkler heads from each other Correct answer Color
Codes
A chemical process of oxidation, which occurs at a rate
fast enough to produce heat and usually light in the form
of either a glow or a flame Correct answer Combustion
A building design feature that aims to limit the fire to its
origin. Correct answer Compartmentation
Located at the origin, these should be considered
individually during the development of a cause hypothesis
Correct answer Competent Ignition Source
This should be donned when dealing with hazardous
chemicals Correct answer Complete PPE
An example of heat transfer, when the heating of a steel
beam to an unexposed part of a building results in a fire in
that location Correct answer Conduction
Overheating on a circuit is most likely to occur at this
location on a circuit Correct answer Connection Points
,Consensus agreement between interested parties should
be developed prior to the commencement of WHAT?
Correct answer Joint Investigation
Complicated patterns in glass Correct answer Crazing
A type of scene or circumstances, in which fires do NOT
always destroy all physical evidence Correct answer
Crime Scenes
A factor in OHM's law that can be calculated if you know
resistance and voltage Correct answer Current
(amperage)
The reasoning in the scientific method used to test an
hypothesis Correct answer Deductive Reasoning
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) Correct answer
Deductive Reasoning
Type of evidence consisting of tangible items
*as opposed to Testimonial Evidence or Documentary
(written) Evidence Correct answer Demonstrative
Evidence
,A burn pattern analysis that is MORE useful for evaluating
fire spread, rather than length or intensity of burning
Correct answer 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 Correct answer
Differential
The ordinary sustained burning mode in most fires Correct
answer 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 Correct answer
Document and Carefully Move
What type of evidence is an investigator's report? Correct
answer Documentary Evidence
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. Correct answer
Documentation
The standards that gas cylinders must conform to
(Dept. of Transportation) Correct answer DOT Standards
, Types of fuses that have one element for overloads and
another element for short circuits Correct answer Dual
Element Fuses
A particular type of an explosion that does NOT often
result in pronounced seats of explosion Correct answer
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. Correct answer 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. Correct answer Engine Oil
Analysis
The fire scene itself needs to be considered as WHAT?
Correct answer Evidence
The process of photographing an item, then collecting,
tagging and putting it in a log Correct answer Evidence
Collection
The importance of this fire investigative practice is no
different in wildfire investigations, compared to structural
fires. Correct answer Evidence Collection and
Documentation
