Latest 2024 Questions and Correct
Answers Rated A+
Evidence - Demonstrative -ANSWER-Tangible items; see, touch,
smell, hear.
Evidence - Documentary -ANSWER-Written form; business records,
banking, calendars, phone records, fire reports, etc...
Evidence - Testimonial -ANSWER-Competent live witness speaking
under oath; two types; fact and expert
Evidence - illustrative -ANSWER-Photos, sketches, maps, diagrams.
Modes are frequently used at trial.
Evidence - illustravtive -ANSWER-Photos and Videos; what, why,
how, when
Evidence collection -ANSWER-Document in place, document the
collection, use proper container, (flag, bag, & tag)
Evidence - collection -ANSWER-Fuel gas powered tools outside the
perimeter. Find out where tools were refuels.
Heat transfer -ANSWER-Conduction, convection, radiation
Interviews -ANSWER-Purpose of the interview; prepare for the
interview, document the interview
,Vehicle Fires -ANSWER-Sparks from an aluminum wheel are not a
competent ignition source.
Vehicle Fires -ANSWER-The most common source of an open flame
in a vehicle is an exhaust system backfire out of a carburetor.
Vehicle Fires -ANSWER-Carburetor backfire leaves a distinct pattern
on the hood.
Vehicle Fires -ANSWER-Two basic fuel systems: vacuum/low
pressure carbureted system, and high-pressure, fuel injected system.
Vehicle Fires -ANSWER-Loose battery connections; not over-current
protected; loose connections can result in intermittent arcing.
Vehicle Fires -ANSWER-Power steering fluid: Flashpoint 347-356*F,
autoignition 680-720*F.
Vehicle Fires -ANSWER-Automatic Transmission Fluid: Flashpoint
302-536*F, autoignition 626-716*F.
Vehicle Fires -ANSWER-Overcharging a battery does not cause it to
explode.
Explosions -ANSWER-Low order damage: characterized by walls
bulge out or laid down, virtually intact, next to the structure. roofs
slightly left.
Explosions -ANSWER-High order damage: shattering of the structure,
producing small debris pieces.
,Explosions -ANSWER-Post blast effects: burned debris away-fire
preceded, unburned the debris away-no fire.
Explosions -ANSWER-Dust explosions: most often occur in confined
areas of relatively wide dispersal.
Explosions -ANSWER-Search 1.5 times further than the farthest piece
of debris.
Fire effects/ fire patterns -ANSWER-Char shrinks as it forms. More
reliable for evaluating fire spread, deduce the direction based on
depth, large shiny blisters (alligatoring) is not evidence of the use of
an accelerant.
Fire effects/fire patterns -ANSWER-Spalling: loss of surface material
due to cracking, breaking, chipping, breakdown in surface tensile
strength, moisture present in the concrete, may appear lighter in color.
Fire effects/fire patterns -ANSWER-Crazed glass: caused by rapid
cooling.
Fire effects/fire patterns -ANSWER-Light bulbs 25W or more "pull"
(gases expand and bubble out); 25W or less contain a vacuum and
can pull in.
Fire effects/fire patterns -ANSWER-Annealing (softening) of springs
may provide clues concerning direction, duration, and intensity.
Fire effects/fire patterns -ANSWER-Saddle burns - A U-shaped burn
pattern found on the top of floor joists, caused by fire burning down
through the floor. Often, a saddle burn is caused by a burning liquid on
, the floor or radiant heat from a material close to the floor. Saddle
burns display deep charring.
Fire effects/fire patterns -ANSWER-Inverted cone burns are indicative
of the vertical flame plume not reaching the ceiling, short-lived fires
with a low HRR
Fire effects/fire patterns -ANSWER-Melting Temperatures: Copper
1981*F; Aluminum 1220*F; Steel 2760*F
Heat Sources -ANSWER-Mechanical: converted to heat when two
materials rub against each other and create friction.
Chemical: chemical reaction; exothermic and endothermic.
Electrical: Converted to heat energy; flowing through a conductor.
Nuclear: splitting the nucleus of an atom into two smaller nuclei
(nuclear fission)
Electrical -ANSWER-Resistance Heating: properly installed, produces
low resistance.
Loose connections: high resistance with increased heating at the
contact.
Electrical -ANSWER-Ground Fault: the purpose if grounding an
electrical system is to make sure that any housings or exposed metal
in the system or connected to it cannot become electrically charged.
Electrical -ANSWER-Sleeving: the softening and sagging of
thermoplastic conductor insulation due to the heating of the conductor.
