Act or Omission - ANS Two factors or situations leading to a fire that may show the nature of
the incident responsibility.
Admiralty Law - ANS A law that may govern the fire investigation of a boat
After-market Equipment - ANS A type of device in a vehicle, which can cause an electrical
overload to factory installed wiring
Alive and Breathing - ANS Evidence of smoke or soot in the lungs, bronchi, and trachea is one

at the fire or explosion scene
Melting Temperature of Aluminum - ANS 1220°F
Aluminum-to-pavement sparks - ANS Considered a competent ignition source.
Heat Release Rate - ANS A meaningful analysis of a fire requires an understanding of the fire
growth, the total heat released, and WHAT?

represents what?
ASTM - ANS The organization that develops standard methods for testing materials.
Auto-ignition - ANS Initiation of combustion by heat but without a spark or flame.
Backdraft - ANS A deflagration resulting from the sudden introduction of air into a confined
space containing oxygen-deficient products of incomplete combustion.
Backfire Flame Arrestor - ANS A boat device that owners fail to keep clean, which is a
frequent cause of engine compartment fires on boats.
Ballast - ANS A device on a fluorescent light fixture that transforms the voltage from normal
household voltage to a higher voltage.

Bimetallic Thermostats - ANS The component that controls temperature in many heat-
producing appliances.
BLEVE - ANS This may occur when the vapor pressure of a liquid exceeds atmospheric
pressure.
Boiling Point - ANS The temperature or point at which the vapor pressure of a liquid equals
the external pressure applied.
Bonding - ANS The process of electrically connecting two or more conductive objects.
Bottom Passenger Side of the Windshield - ANS Most engine fires typically penetrate the
interior compartment at this location of the vehicle.
Brass Prongs (male ends) - ANS An investigator can closely examine this component of a cord
to determine if it was plugged into a receptacle.
Calcination - ANS The chemical and physical changes that occur in gypsum wallboard
surfaces during a fire.
Carbon Monoxide - ANS A narcotic gas that one might be exposed to in the fire.
Carbon Monoxide Poisoning - ANS 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 - ANS This occurrence is the most common open-flame ignition source in
non-fuel injected vehicles.
