• 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), what is the wattage?
*Power (P) = current (I) x voltage (V)
Watts = amps x volts
• 1987 . CORRECT ANSWER: The year of the first edition of NFPA 1033

perimeter of a blast scene
*That is, the distance from the furthest debris
• 1100°F . CORRECT ANSWER: What temperature in the upper gas layer causes
the onset of Flashover?
• 1960°F . CORRECT ANSWER: The temperature at which copper melts
• 2 W/cm2 . CORRECT ANSWER: The measurement of the radiant heat flux
(from gas layer to the floor) that indicates the onset of flashover
,• 240 volts . CORRECT ANSWER: The voltage between the two hot wires at the
service entrance cables in most single-family residences in the United States
(single-phase service with three wires)
• 3 years . CORRECT ANSWER: The revision cycle for NFPA 921 (timespan)
• 350°F . CORRECT ANSWER: The flash point of power steering fluid
• 35-70 p.s.i. . CORRECT ANSWER: In high-pressure fuel-injected vehicles, this
is the typical range of pressure that is used to pump fuel from a fuel tank
• 5 and 17 . CORRECT ANSWER: The lower explosive and upper explosive limit
of natural gas (methane)?
• 680°F . CORRECT ANSWER: The ignition temperature of power steering fluid
• Fuel . CORRECT ANSWER: Any substance that can undergo combustion
• Act or Omission . CORRECT ANSWER: Two factors or situations leading to a
fire that may show the nature of the incident responsibility.
• Additional Investigative Recommendations . CORRECT ANSWER: This
concept should not be 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
• Alive and Breathing . CORRECT ANSWER: 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 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
