Joint Investigation --- correct answer ---Consensus agreement
between interested parties should be developed prior to the
commencement of WHAT?
Crazing --- correct answer ---Complicated patterns in glass
Crime Scenes --- correct answer ---A type of scene or circumstances,
in which fires do NOT always destroy all physical evidence
Current (amperage) --- correct answer ---A factor in OHM's law that
can be calculated if you know resistance and voltage
Deductive Reasoning --- correct answer ---The reasoning in the
scientific method used to test an hypothesis
Deductive Reasoning --- correct answer ---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)
Demonstrative Evidence --- correct answer ---Type of evidence
consisting of tangible items
*as opposed to Testimonial Evidence or Documentary (written)
Evidence
Depth of Char --- correct answer ---A burn pattern analysis that is
MORE useful for evaluating fire spread, rather than length or
intensity of burning
Differential --- correct answer ---All voltages are _________________,
which means that a battery or DC generator creates a potential
difference that can force charge through a wire
Diffusion Flame Burning --- correct answer ---The ordinary sustained
burning mode in most fires
,Document and Carefully Move --- correct answer ---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
Documentary Evidence --- correct answer ---What type of evidence is
an investigator's report?
Documentation --- correct answer ---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.
DOT Standards --- correct answer ---The standards that gas cylinders
must conform to
(Dept. of Transportation)
Dual Element Fuses --- correct answer ---Types of fuses that have one
element for overloads and another element for short circuits
Dust Explosion --- correct answer ---A particular type of an explosion
that does NOT often result in pronounced seats of explosion
, Dust Explosion --- correct answer ---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.
Engine Oil Analysis --- correct answer ---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 --- correct answer ---The fire scene itself needs to be
considered as WHAT?
Evidence Collection --- correct answer ---The process of
photographing an item, then collecting, tagging and putting it in a log
Evidence Collection and Documentation --- correct answer ---The
importance of this fire investigative practice is no different in wildfire
investigations, compared to structural fires.
Evidence Custodian --- correct answer ---The person at a fire scene
who manages various aspects of the evidence collection process,
