✔✔Aluminum-to-pavement sparks - ✔✔Which one of these is NOT considered a
competent ignition source?
Metal-to-metal sparks,
Aluminum-to-pavement sparks,
Metal-to-pavement sparks,
Motor bearing sparks
✔✔Heat Release Rate - ✔✔A meaningful analysis of a fire requires an understanding of
the fire growth, the total heat released, and WHAT?
✔✔Arc-fault circuit interrupter - ✔✔What does he term AFCI stand for? And, the "A"
specifically represents what?
✔✔ASTM - ✔✔The organization that develops standard methods for testing materials
✔✔Auto-ignition - ✔✔Initiation of combustion by heat but without a spark or flame
✔✔Backdraft - ✔✔A deflagration resulting from the sudden introduction of air into a
confined space containing oxygen-deficient products of incomplete combustion
✔✔Backdraft - ✔✔An explosion caused by a combination of combustible materials
heated to the ignition point and a sudden introduction of oxygen to support combustion
✔✔Backfire Flame Arrestor - ✔✔A boat device that owners fail to keep clean, which is a
frequent cause of engine compartment fires on boats
✔✔Ballast - ✔✔A device on a fluorescent light fixture that transforms the voltage from
normal household voltage to a higher voltage
✔✔Battery - ✔✔The starter motor draws its energy from this source
✔✔Beyond a Reasonable Doubt - ✔✔The burden of proof in a criminal trial
✔✔Bimetallic Thermostats - ✔✔The component that controls temperature in many heat-
producing appliances
✔✔BLEVE - ✔✔This may occur when the vapor pressure of a liquid exceeds
atmospheric pressure
*And this is the most common mechanical explosion
,✔✔Boiling Point - ✔✔The temperature or point at which the vapor pressure of a liquid
equals the external pressure applied
✔✔Bonding - ✔✔The process of electrically connecting two or more conductive objects
✔✔Bottom Passenger Side of the Windshield - ✔✔Most engine fires typically penetrate
the interior compartment at this location of the vehicle
✔✔Brass Prongs (male ends) - ✔✔An investigator can closely examine this component
of a cord to determine if it was plugged into a receptacle
✔✔Calcination - ✔✔The chemical and physical changes that occur in gypsum wallboard
surfaces during a fire
✔✔Carbon Monoxide - ✔✔A narcotic gas that one might be exposed to in the fire
✔✔Carbon Monoxide - ✔✔The levels of this toxin dissipate over time after removal from
the fire environment.
✔✔Carbon Monoxide Poisoning - ✔✔This toxic condition does NOT cause a cherry-pink
coloration to the skin of the fire victim and is NOT visible on all skin types
✔✔Carburetor Backfire - ✔✔This occurrence is the most common open-flame ignition
source in non-fuel injected vehicles
✔✔Ceiling jet - ✔✔When the fire plume reaches the ceiling of a room and moves
laterally along the ceiling
✔✔Christmas Tree - ✔✔An item in the home that burns at a peak HRR of 3000-
5000kW, which is hotter than a pool of gasoline or a polyurethane chair
✔✔Clean Burn - ✔✔This occurs when intense radiated heat or direct flame contacts a
surface during the fire, burning away deposits
✔✔Collapsed Furniture Springs - ✔✔This is a fire effect to furniture that does NOT
provide the investigators with clues concerning the type of ignition source, but can show
fire spread and intensity
✔✔Color - ✔✔A fire characteristic that is NOT necessarily an accurate indicator of the
flame temperature
✔✔Color Codes - ✔✔This feature distinguishes the heat-sensitive bulbs of sprinkler
heads from each other
, ✔✔Combustion - ✔✔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
✔✔Compartmentation - ✔✔A building design feature that aims to limit the fire to its
origin.
✔✔Competent Ignition Source - ✔✔Located at the origin, these should be considered
individually during the development of a cause hypothesis
✔✔Complete PPE - ✔✔This should be donned when dealing with hazardous chemicals
✔✔Conduction - ✔✔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
✔✔Connection Points - ✔✔Overheating on a circuit is most likely to occur at this
location on a circuit
✔✔Joint Investigation - ✔✔Consensus agreement between interested parties should be
developed prior to the commencement of WHAT?
✔✔Crazing - ✔✔Complicated patterns in glass
✔✔Crime Scenes - ✔✔A type of scene or circumstances, in which fires do NOT always
destroy all physical evidence
✔✔Current (amperage) - ✔✔A factor in OHM's law that can be calculated if you know
resistance and voltage
✔✔Deductive Reasoning - ✔✔The reasoning in the scientific method used to test an
hypothesis
✔✔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)
✔✔Demonstrative Evidence - ✔✔Type of evidence consisting of tangible items
*as opposed to Testimonial Evidence or Documentary (written) Evidence
