IAAI CFI STUDY QUESTIONS & ANSWERS COMPILED TO ASSIST IN PREPARATION FOR THE IAAI CFI CERTIFICATION TEST) ALREADY GRADED A+ NEWLY UPDATED 2025. Combustible Liquid - ANS-A liquid with a flash point ABOVE 100F 12.5 - ANS-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 - ANS-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 - ANS-The year of the first edition of NFPA 1033 1.5 times - ANS-The recommended distance for securing the perimeter of a blast scene *That is, the distance from the furthest debris 1100°F - ANS-What temperature in the upper gas layer causes the onset of Flashover? 1960°F - ANS-The temperature at which copper melts 2 W/cm2 - ANS-The measurement of the radiant heat flux (from gas layer to the floor) that indicates the onset of flashover 240 volts - ANS-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 - ANS-The revision cycle for NFPA 921 (timespan) 350°F - ANS-The flash point of power steering fluid 35-70 p.s.i. - ANS-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 - ANS-The lower explosive and upper explosive limit of natural gas (methane)? 680°F - ANS-The ignition temperature of power steering fluid Fuel - ANS-Any substance that can undergo combustion Act or Omission - ANS-Two factors or situations leading to a fire that may show the nature of the incident responsibility. Additional Investigative Recommendations - ANS-This concept should not be included in a summary report of findings. Admiralty Law - ANS-A law that may govern the fire investigation of a boat After-market Equipment - ANS-A type of device in a vehicle, which can cause an electrical overload to factory installed wiring Alive and Breathing - ANS-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 - ANS-Those who have the responsibility for monitoring safety conditions at the fire or explosion scene 1220°F - ANS-The melting temperature of aluminum Aluminum-to-pavement sparks - ANS-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 - ANS-A meaningful analysis of a fire requires an understanding of the fire growth, the total heat released, and WHAT? Arc-fault circuit interrupter - ANS-What does he term AFCI stand for? And, the "A" specifically represents what? ASTM - ANS-The organization that develops standard methods for testing materials Auto-ignition - ANS-Initiation of combustion by heat but without a spark or flame Backdraft - ANS-A deflagration resulting from the sudden introduction of air into a confined space containing oxygen-deficient products of incomplete combustion Backdraft - ANS-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 - ANS-A boat device that owners fail to keep clean, which is a frequent cause of engine compartment fires on boats Ballast - ANS-A device on a fluorescent light fixture that transforms the voltage from normal household voltage to a higher voltage Battery - ANS-The starter motor draws its energy from this source Beyond a Reasonable Doubt - ANS-The burden of proof in a criminal trial Bimetallic Thermostats - ANS-The component that controls temperature in many heat-producing appliances BLEVE - ANS-This may occur when the vapor pressure of a liquid exceeds atmospheric pressure *And this is the most common mechanical explosion Boiling Point - ANS-The temperature or point at which the vapor pressure of a liquid equals the external pressure applied Bonding - ANS-The process of electrically connecting two or more conductive objects Bottom Passenger Side of the Windshield - ANS-Most engine fires typically penetrate the interior compartment at this location of the vehicle Brass Prongs (male ends) - ANS-An investigator can closely examine this component of a cord to determine if it was plugged into a receptacle Calcination - ANS-The chemical and physical changes that occur in gypsum wallboard surfaces during a fire Carbon Monoxide - ANS-A narcotic gas that one might be exposed to in the fire Carbon Monoxide - ANS-The levels of this toxin dissipate over time after removal from the fire environment. Carbon Monoxide Poisoning - ANS-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 - ANS-This occurrence is the most common open-flame ignition source in non-fuel injected vehicles Ceiling jet - ANS-When the fire plume reaches the ceiling of a room and moves laterally along the ceiling Christmas Tree - ANS-An item in the home that burns at a peak HRR of kW, which is hotter than a pool of gasoline or a polyurethane chair Clean Burn - ANS-This occurs when intense radiated heat or direct flame contacts a surface during the fire, burning away deposits Collapsed Furniture Springs - ANS-This is a fire effect to furniture that does NOT provide the investigators with clues concerning the type of ignition source, but can show fire spread and intensity Color - ANS-A fire characteristic that is NOT necessarily an accurate indicator of the flame temperature Color Codes - ANS-This feature distinguishes the heat-sensitive bulbs of sprinkler heads from each other Combustion - ANS-A chemical process of oxidation, which occurs at a rate fast enough to produce heat and usually light in the form of either a glow or a flame Compartmentation - ANS-A building design feature that aims to limit the fire to its origin. Competent Ignition Source - ANS-Located at the origin, these should be considered individually during the development of a cause hypothesis Complete PPE - ANS-This should be donned when dealing with hazardous chemicals Conduction - ANS-An example of heat transfer, when the heating of a steel beam to an unexposed part of a building results in a fire in that location Connection Points - ANS-Overheating on a circuit is most likely to occur at this location on a circuit Joint Investigation - ANS-Consensus agreement between interested parties should be developed prior to the commencement of WHAT? Crazing - ANS-Complicated patterns in glass Crime Scenes - ANS-A type of scene or circumstances, in which fires do NOT always destroy all physical evidence Continues...
