Combustible Liquid - Correct answer-A liquid with a flash point ABOVE 100F
12.5 - Correct answer-If the current flowing out from an electrical panel is 12.5 amps,
and it then flows through an electrical load of 1500 watts, what is the amperage of the
remaining current flow of the return circuit?
1000 - Correct answer-If a hair dryer draws 8.3amps (in a home with 120-volt service),

included in a summary report of findings.
Admiralty Law - Correct answer-A law that may govern the fire investigation of a boat
After-market Equipment - Correct answer-A type of device in a vehicle, which can cause
an electrical overload to factory installed wiring

and trachea is one of the most significant factors in confirming that, at the time of the
fire, the victim was WHAT?
All Team Members - Correct answer-Those who have the responsibility for monitoring
safety conditions at the fire or explosion scene
1220°F - Correct answer-The melting temperature of aluminum
Aluminum-to-pavement sparks - Correct answer-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 - Correct answer-A meaningful analysis of a fire requires an
understanding of the fire growth, the total heat released, and WHAT?
Arc-fault circuit interrupter - Correct answer-What does he term AFCI stand for? And,
the "A" specifically represents what?
ASTM - Correct answer-The organization that develops standard methods for testing
materials
Auto-ignition - Correct answer-Initiation of combustion by heat but without a spark or
flame
Backdraft - Correct answer-A deflagration resulting from the sudden introduction of air
into a confined space containing oxygen-deficient products of incomplete combustion
, Backdraft - Correct answer-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 - Correct answer-A boat device that owners fail to keep clean,
which is a frequent cause of engine compartment fires on boats
Ballast - Correct answer-A device on a fluorescent light fixture that transforms the
voltage from normal household voltage to a higher voltage
Battery - Correct answer-The starter motor draws its energy from this source
Beyond a Reasonable Doubt - Correct answer-The burden of proof in a criminal trial
Bimetallic Thermostats - Correct answer-The component that controls temperature in
many heat-producing appliances
BLEVE - Correct answer-This may occur when the vapor pressure of a liquid exceeds
atmospheric pressure
*And this is the most common mechanical explosion
Boiling Point - Correct answer-The temperature or point at which the vapor pressure of
a liquid equals the external pressure applied
Bonding - Correct answer-The process of electrically connecting two or more conductive
objects
Bottom Passenger Side of the Windshield - Correct answer-Most engine fires typically
penetrate the interior compartment at this location of the vehicle
Brass Prongs (male ends) - Correct answer-An investigator can closely examine this
component of a cord to determine if it was plugged into a receptacle
Calcination - Correct answer-The chemical and physical changes that occur in gypsum
wallboard surfaces during a fire
Carbon Monoxide - Correct answer-A narcotic gas that one might be exposed to in the
fire
Carbon Monoxide - Correct answer-The levels of this toxin dissipate over time after
removal from the fire environment.
Carbon Monoxide Poisoning - Correct answer-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
