IAAI CFI Study Questions (2021)
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), 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
1.5 times - correct answer The recommended distance for securing the 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
,IAAI CFI Study Questions (2021)
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
, IAAI CFI Study Questions (2021)
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
Combustible Liquid - correct answer A liquid with a flash point ABOVE 100F
