• Admiralty Law -✓✓ A law that may govern the fire investigation of a boat
,• After-market Equipment -✓✓ A type of device in a vehicle, which can cause an
electrical overload to factory installed wiring
• Alive and Breathing -✓✓ Evidence of smoke or soot in the lungs, bronchi, and trachea
is one of the most significant factors in confirming that, at the time of the fire, the victim
was alive.
• All Team Members -✓✓ Those who have the responsibility for monitoring safety
conditions at the fire or explosion scene
• Melting Temperature of Aluminum -✓✓ 1220°F
• Aluminum-to-pavement sparks -✓✓ Considered a competent ignition source.
• 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 the 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.
• 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.
, • 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 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.
