records, banking, calendars, phone records, fire reports, etc...
Evidence - Testimonial - ....🔰VERIFIED ANSWERS.... ✔✔Competent live witness speaking
under oath; two types; fact and expert
Evidence - illustrative - ....🔰VERIFIED ANSWERS.... ✔✔Photos, sketches, maps, diagrams.
Modes are frequently used at trial.
Evidence - illustravtive - ....🔰VERIFIED ANSWERS.... ✔✔Photos and Videos; what, why,
how, when
Evidence collection - ....🔰VERIFIED ANSWERS.... ✔✔Document in place, document the
collection, use proper container, (flag, bag, & tag)
Evidence - collection - ....🔰VERIFIED ANSWERS.... ✔✔Fuel gas powered tools outside the
perimeter. Find out where tools were refuels.
Heat transfer - ....🔰VERIFIED ANSWERS.... ✔✔Conduction, convection, radiation
Interviews - ....🔰VERIFIED ANSWERS.... ✔✔Purpose of the interview; prepare for the
interview, document the interview
,Vehicle Fires - ....🔰VERIFIED ANSWERS.... ✔✔Sparks from an aluminum wheel are not a
competent ignition source.
Vehicle Fires - ....🔰VERIFIED ANSWERS.... ✔✔The most common source of an open
flame in a vehicle is an exhaust system backfire out of a carburetor.
Vehicle Fires - ....🔰VERIFIED ANSWERS.... ✔✔Carburetor backfire leaves a distinct
pattern on the hood.
Vehicle Fires - ....🔰VERIFIED ANSWERS.... ✔✔Two basic fuel systems: vacuum/low
pressure carbureted system, and high-pressure, fuel injected system.
Vehicle Fires - ....🔰VERIFIED ANSWERS.... ✔✔Loose battery connections; not over-
current protected; loose connections can result in intermittent arcing.
Vehicle Fires - ....🔰VERIFIED ANSWERS.... ✔✔Power steering fluid: Flashpoint 347-
356*F, autoignition 680-720*F.
Vehicle Fires - ....🔰VERIFIED ANSWERS.... ✔✔Automatic Transmission Fluid: Flashpoint
302-536*F, autoignition 626-716*F.
Vehicle Fires - ....🔰VERIFIED ANSWERS.... ✔✔Overcharging a battery does not cause it to
explode.
Explosions - ....🔰VERIFIED ANSWERS.... ✔✔Low order damage: characterized by walls
bulge out or laid down, virtually intact, next to the structure. roofs slightly left.
Explosions - ....🔰VERIFIED ANSWERS.... ✔✔High order damage: shattering of the
structure, producing small debris pieces.
, Explosions - ....🔰VERIFIED ANSWERS.... ✔✔Post blast effects: burned debris away-fire
preceded, unburned the debris away-no fire.
Explosions - ....🔰VERIFIED ANSWERS.... ✔✔Dust explosions: most often occur in
confined areas of relatively wide dispersal.
Explosions - ....🔰VERIFIED ANSWERS.... ✔✔Search 1.5 times further than the farthest
piece of debris.
Fire effects/ fire patterns - ....🔰VERIFIED ANSWERS.... ✔✔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 - ....🔰VERIFIED ANSWERS.... ✔✔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 - ....🔰VERIFIED ANSWERS.... ✔✔Crazed glass: caused by rapid
cooling.
Fire effects/fire patterns - ....🔰VERIFIED ANSWERS.... ✔✔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 - ....🔰VERIFIED ANSWERS.... ✔✔Annealing (softening) of
springs may provide clues concerning direction, duration, and intensity.
Fire effects/fire patterns - ....🔰VERIFIED ANSWERS.... ✔✔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.
