Sparks from an aluminum wheel are not a competent ignition source. - Correct Answer
✔✔ Vehicle Fires
The most common source of an open flame in a vehicle is an exhaust system backfire
out of a carburetor. - Correct Answer ✔✔ Vehicle Fires
Carburetor backfire leaves a distinct pattern on the hood. - Correct Answer ✔✔ Vehicle
Fires
Two basic fuel systems: vacuum/low pressure carbureted system, and high-pressure,
fuel injected system. - Correct Answer ✔✔ Vehicle Fires
Loose battery connections; not over-current protected; loose connections can result in
intermittent arcing. - Correct Answer ✔✔ Vehicle Fires
, Power steering fluid: Flashpoint 347-356*F, autoignition 680-720*F. - Correct Answer
✔✔ Vehicle Fires
Automatic Transmission Fluid: Flashpoint 302-536*F, autoignition 626-716*F. - Correct
Answer ✔✔ Vehicle Fires
Overcharging a battery does not cause it to explode. - Correct Answer ✔✔ Vehicle Fires
Low order damage: characterized by walls bulge out or laid down, virtually intact, next to
the structure. roofs slightly left. - Correct Answer ✔✔ Explosions
High order damage: shattering of the structure, producing small debris pieces. - Correct
Answer ✔✔ Explosions
Post blast effects: burned debris away-fire preceded, unburned the debris away-no fire.
- Correct Answer ✔✔ Explosions
Dust explosions: most often occur in confined areas of relatively wide dispersal. -
Correct Answer ✔✔ Explosions
Search 1.5 times further than the farthest piece of debris. - Correct Answer ✔✔
Explosions
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. - Correct Answer ✔✔ Fire effects/ fire patterns
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. -
Correct Answer ✔✔ Fire effects/fire patterns
Crazed glass: caused by rapid cooling. - Correct Answer ✔✔ Fire effects/fire patterns
Light bulbs 25W or more "pull" (gases expand and bubble out); 25W or less contain a
vacuum and can pull in. - Correct Answer ✔✔ Fire effects/fire patterns
Annealing (softening) of springs may provide clues concerning direction, duration, and
intensity. - Correct Answer ✔✔ Fire effects/fire patterns
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. - Correct Answer ✔✔ Fire effects/fire patterns
