IAAI CFI EXAM 2026 Edition Actual Questions And Correct Detailed Answers
Fire Growth Rate-ANSWER=Once a fuel is ignited in a motor vehicle, any additional fuels contained in the
vehicle have significant effect on fire intensity.
Fire Intensity-ANSWER=Ina wildland fire, this fire characteristic is indicated by the degree of damage to the
wildland fuel
Fire Origin-ANSWER=This investigative determination is based on witness information, fire patterns, arc
mapping, and fire dynamics
Fire Scene Access-ANSWER=The fifth and sixth amendments DO NOT answer questions regarding
constitutional protections in relation to fire investigation aspect (4th amendment issue)
Fire Scene Reconstruction-ANSWER=Recreating pre-fire positions of contents
Fire-rated Door - ANSWER=This type of door must be used when installed in a fire-rated wall.
First or Second Degree Burns-ANSWER=This is the typical extent of thermal injuries sustained from an
explosion flame front, due to the very short duration.
Flame Spread Rating-ANSWER=Asystem used to rate a material's flame spread potential.
Class A:Flame spread indeexpSWER=0-25
Class B:Flame spread indexpSWER=26-75
,2|Page
Class C: Flame spread index-ANSWER=76-200
Flammable Gases-ANSWER=This type of fuel can only be ignited by a spark or pilot flame over specific ranges
of gas concentration.
Flammable Liquid-ANSWER=Aliquid with a flash point below 100 F.
∗
Flash point-ANSWER=The characteristic of an appropriate mixture of vapor-to-air, which will cause it to ignite
when subjected to an ignition source.
Combustible Liquid-ANSWER=Aliquid with a flash point ABOVE 100F
Current Flow-ANSWER=Ifthe 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?
Power(P)-ANSWER=POWe(P)=current(I) x voltage (V)
Watts-ANSWER=Watts=amps×volts
Year of NFPA 1033 First Edition-ANSWER=1987
Recommended Distance for Securing Blast Scene-ANSWER=1.5 times the distance from the furthest debris
Onset of Flashover Temperature-ANSWER=1100°F
,3|Page
Copper Melting Temperature-ANSWER=1960°F
Radiant Heat Flux Measurement-ANSWER=2W/cm2 indicates the onset of flashover
Voltage at Service Entrance Cables-ANSWER=240 volts between the two hot wires in most single-family
residences in the United States
NFPA 921 Revision Cycle-ANSWER=3 years
Flash Point of Power Steering Fluid-ANSWER=350°F
Typical Pressure in High-Pressure Fuel-Injected Vehicles-ANSWER=35-70 p.s.i.
Lower and Upper Explosive Limit of Natural Gas-ANSWER=5and 17
Ignition Temperature of Power Steering Fluid-ANSWER=680°F
Fuel - ANSWER=Any substance that can undergo comnbustion
Act or Omission-ANSWER=Two factors or situations leading to a fire that may show the nature of the incident
responsibility.
Admiralty Law-ANSWER=Alaw that may govern the fire investigation of a boat
After-market Equipment-ANSWER=Atype of device in a vehicle, which can cause an electrical overload to
factory installed wiring
, 4/Page
Alive and Breathing-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 alive.
All Team Members-ANSWER=Those who have the responsibility for monitoring safety conditions at the
fire or explosion scene
Melting Temperature of Aluminum-ANSWER=1220°F
Aluminum-to-pavement sparks-ANSWER=Considered a competent ignition source.
Heat Release Rate-ANSWER=Ameaningful analysis of a fire requires an understanding of the fire growth, the
total heat released, and WHAT?
′ ′
Arc-fault circuit interrupter-ANSWER=What does the termAFCI stand for? And,the A specifically
represents what?
ASTM- ANSWER=The organization that develops standard methods for testing materials.
Auto-ignition-ANSWER=Initiation of combustion by heat but without a spark or flame.
Backdraft-ANSWER=Adeflagration resulting from the sudden introduction of air into a confined space
containing oxygen-deficient products of incomplete combustion.
Backfire Flame Arrestor-ANSWER=Aboat device that owners fail to keep clean, which is a frequent cause
of engine compartment fires on boats.
Ballast-ANSWER=Adevice on a fluorescent light fixture that transforms the voltage from normal
household voltage to a higher voltage.
