IAAI CFI EXAM-2025 IAAI CFI
CERTIFICATION TEST PREP
Combustible Liquid - A liquid with a flash point ABOVE 100F
12.5 - 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 - 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 - The year of the first edition of NFPA 1033
1.5 times - The recommended distance for securing the perimeter of a blast scene
*That is, the distance from the furthest debris
1100°F - What temperature in the upper gas layer causes the onset of Flashover?
1960°F - The temperature at which copper melts
2 W/cm2 - The measurement of the radiant heat flux (from gas layer to the floor) that indicates
the onset of flashover
240 volts - 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 - The revision cycle for NFPA 921 (timespan)
350°F - The flash point of power steering fluid
35-70 p.s.i. - 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 - The lower explosive and upper explosive limit of natural gas (methane)?
680°F - The ignition temperature of power steering fluid
Fuel - Any substance that can undergo combustion
,Act or Omission - Two factors or situations leading to a fire that may show the nature of the
incident responsibility.
Additional Investigative Recommendations - This concept should not be included in a summary
report of findings.
Admiralty Law - A law that may govern the fire investigation of a boat
After-market Equipment - A type of device in a vehicle, which can cause an electrical overload
to factory installed wiring
Alive and Breathing - 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 - Those who have the responsibility for monitoring safety conditions at the
fire or explosion scene
1220°F - The melting temperature of aluminum
Aluminum-to-pavement sparks - 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 - A meaningful analysis of a fire requires an understanding of the fire growth,
the total heat released, and WHAT?
Arc-fault circuit interrupter - What does he term AFCI stand for? And, the "A" specifically
represents what?
ASTM - The organization that develops standard methods for testing materials
Auto-ignition - Initiation of combustion by heat but without a spark or flame
Backdraft - A deflagration resulting from the sudden introduction of air into a confined space
containing oxygen-deficient products of incomplete combustion
Backdraft - 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 - A boat device that owners fail to keep clean, which is a frequent cause
of engine compartment fires on boats
, Ballast - A device on a fluorescent light fixture that transforms the voltage from normal
household voltage to a higher voltage
Battery - The starter motor draws its energy from this source
Beyond a Reasonable Doubt - The burden of proof in a criminal trial
Bimetallic Thermostats - The component that controls temperature in many heat-producing
appliances
BLEVE - This may occur when the vapor pressure of a liquid exceeds atmospheric pressure
*And this is the most common mechanical explosion
Boiling Point - The temperature or point at which the vapor pressure of a liquid equals the
external pressure applied
Bonding - The process of electrically connecting two or more conductive objects
Bottom Passenger Side of the Windshield - Most engine fires typically penetrate the interior
compartment at this location of the vehicle
Brass Prongs (male ends) - An investigator can closely examine this component of a cord to
determine if it was plugged into a receptacle
Calcination - The chemical and physical changes that occur in gypsum wallboard surfaces during
a fire
Carbon Monoxide - A narcotic gas that one might be exposed to in the fire
Carbon Monoxide - The levels of this toxin dissipate over time after removal from the fire
environment.
Carbon Monoxide Poisoning - 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 - This occurrence is the most common open-flame ignition source in non-
fuel injected vehicles
Ceiling jet - When the fire plume reaches the ceiling of a room and moves laterally along the
ceiling
Christmas Tree - An item in the home that burns at a peak HRR of 3000-5000kW, which is
hotter than a pool of gasoline or a polyurethane chair
