IAAI CFI Study Questions (2021)
1. Combustible Liquid: A liquid with a flash point ABOVE 100F
2. 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?
3. 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
4. 1987: The year of the first edition of NFPA 1033
5. 1.5 times: The recommended distance for securing the perimeter of a blast scene
*That is, the distance from the furthest debris
6. 1100°F: What temperature in the upper gas layer causes the onset of Flashover?
7. 1960°F: The temperature at which copper melts
8. 2 W/cm2: The measurement of the radiant heat flux (from gas layer to the floor)
that indicates the onset of flashover
9. 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)
10. 3 years: The revision cycle for NFPA 921 (timespan)
11. 350°F: The flash point of power steering fluid
12. 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
13. 5 and 17: The lower explosive and upper explosive limit of natural gas
(methane)?
, IAAI CFI Study Questions (2021)
14. 680°F: The ignition temperature of power steering fluid
15. Fuel: Any substance that can undergo combustion
16. Act or Omission: Two factors or situations leading to a fire that may show the
nature of the incident responsibility.
17. Additional Investigative Recommendations: This concept should not be in-
cluded in a summary report of findings.
18. Admiralty Law: A law that may govern the fire investigation of a boat
19. After-market Equipment: A type of device in a vehicle, which can cause an
electrical overload to factory installed wiring
20. 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?
, IAAI CFI Study Questions (2021)
21. All Team Members: Those who have the responsibility for monitoring safety
conditions at the fire or explosion scene
22. 1220°F: The melting temperature of aluminum
23. 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
24. Heat Release Rate: A meaningful analysis of a fire requires an understanding
of the fire growth, the total heat released, and WHAT?
25. Arc-fault circuit interrupter: What does he term AFCI stand for? And, the "A"
specifically represents what?
26. ASTM: The organization that develops standard methods for testing materials
27. Auto-ignition: Initiation of combustion by heat but without a spark or flame
28. Backdraft: A deflagration resulting from the sudden introduction of air into a
confined space containing oxygen-deficient products of incomplete combustion
29. Backdraft: An explosion caused by a combination of combustible materials
heated to the ignition point and a sudden introduction of oxygen to support com-
bustion
30. Backfire Flame Arrestor: A boat device that owners fail to keep clean, which is
a frequent cause of engine compartment fires on boats
31. Ballast: A device on a fluorescent light fixture that transforms the voltage from
normal household voltage to a higher voltage
32. Battery: The starter motor draws its energy from this source
