IAAI CFI Study Questions (2025)
1.5 times - ANS-The advocated distance for securing the perimeter of a blast scene

12.5 - ANS-If the cutting-edge flowing out from an electrical panel is 12.Five amps, and it then
flows thru an electrical load of 1500 watts, what is the amperage of the remaining modern drift
of the go back circuit?
1220°F - ANS-The melting temperature of aluminum
1960°F - ANS-The temperature at which copper melts
1987 - ANS-The year of the primary version of NFPA 1033
2 W/cm2 - ANS-The dimension of the radiant warmness flux (from gas layer to the ground) that
shows the onset of flashover
240 volts - ANS-The voltage between the two warm wires at the service front cables in
maximum single-family houses in the United States (single-segment provider with three wires)
three years - ANS-The revision cycle for NFPA 921 (timespan)
35-70 p.S.I. - ANS-In excessive-pressure gasoline-injected cars, this is the everyday variety of
stress this is used to pump fuel from a gas tank
350°F - ANS-The flash factor of strength steering fluid
5 and 17 - ANS-The decrease explosive and higher explosive restriction of herbal gas
(methane)?
680°F - ANS-The ignition temperature of electricity steerage fluid
Act or Omission - ANS-Two factors or conditions main to a hearth that can display the character
of the incident duty.
Additional Investigative Recommendations - ANS-This idea should not be protected in a
summary file of findings.
Admiralty Law - ANS-A law that can govern the hearth investigation of a boat
After-marketplace Equipment - ANS-A form of tool in a vehicle, that may purpose an electrical
overload to manufacturing facility installed wiring
Alive and Breathing - ANS-Evidence of smoke or soot inside the lungs, bronchi, and trachea is
one of the maximum great elements in confirming that, at the time of the fireplace, the victim
turned into WHAT?
All Team Members - ANS-Those who have the duty for monitoring safety situations on the
hearth or explosion scene
, Aluminum-to-pavement sparks - ANS-Which this kind of is NOT taken into consideration a able
ignition source?
Metal-to-metallic sparks,
Aluminum-to-pavement sparks,
Metal-to-pavement sparks,
Motor bearing sparks
Arc-fault circuit interrupter - ANS-What does he time period AFCI stand for? And, the "A"
specially represents what?
ASTM - ANS-The organisation that develops popular methods for checking out substances
Auto-ignition - ANS-Initiation of combustion by warmth but without a spark or flame
Backdraft - ANS-A deflagration on account of the surprising advent of air right into a restrained
space containing oxygen-poor merchandise of incomplete combustion
Backdraft - ANS-An explosion resulting from a mixture of flamable substances heated to the
ignition point and a surprising creation of oxygen to aid combustion
Backfire Flame Arrestor - ANS-A boat device that owners fail to maintain clean, that is a
common purpose of engine compartment fires on boats
Ballast - ANS-A device on a fluorescent light fixture that transforms the voltage from ordinary
household voltage to a higher voltage
Battery - ANS-The starter motor draws its electricity from this supply
Beyond a Reasonable Doubt - ANS-The burden of proof in a criminal trial
Bimetallic Thermostats - ANS-The element that controls temperature in lots of
warmth-producing appliances
BLEVE - ANS-This may also arise whilst the vapor stress of a liquid exceeds atmospheric stress
*And this is the most common mechanical explosion
Boiling Point - ANS-The temperature or factor at which the vapor pressure of a liquid equals the
outside pressure implemented
Bonding - ANS-The system of electrically connecting or extra conductive gadgets
Bottom Passenger Side of the Windshield - ANS-Most engine fires generally penetrate the
indoors compartment at this region of the vehicle
Brass Prongs (male ends) - ANS-An investigator can carefully look at this element of a wire to
decide if it changed into plugged right into a receptacle
Calcination - ANS-The chemical and physical changes that occur in gypsum wallboard surfaces
at some point of a fireplace
Carbon Monoxide - ANS-A narcotic gas that one might be uncovered to inside the fireplace
Carbon Monoxide - ANS-The ranges of this toxin expend over time after elimination from the fire
environment.
Carbon Monoxide Poisoning - ANS-This poisonous condition does NOT purpose a
cherry-crimson coloration to the skin of the fireplace sufferer and is NOT seen on all skin sorts
Carburetor Backfire - ANS-This occurrence is the most commonplace open-flame ignition
source in non-gasoline injected automobiles
Ceiling jet - ANS-When the fireplace plume reaches the ceiling of a room and movements
laterally alongside the ceiling
