WITH REAL EXAM QUESTIONS ANDVERSIONS
ANSWERS WITH RATIONALES AND A STUDY
GUIDE | EXPERT VERIFIED FOR GUARANTEED PASS
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=In a 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=A system used to rate a material's flame spread potential.
Class A: Flame spread index - ANSWER=0-25
Class B: Flame spread index - ANSWER=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=A liquid 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=A liquid with a flash point ABOVE 100F
Current Flow - ANSWER=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?
Power (P) - ANSWER=Power (P) = current (I) x voltage (V)
Watts - ANSWER=Watts = amps x 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=2 W/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=5 and 17
Ignition Temperature of Power Steering Fluid - ANSWER=680°F
Fuel - ANSWER=Any substance that can undergo combustion
Act or Omission - ANSWER=Two factors or situations leading to a fire that may show the nature
of the incident responsibility.
Admiralty Law - ANSWER=A law that may govern the fire investigation of a boat
After-market Equipment - ANSWER=A type 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=A meaningful 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 term AFCI 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=A deflagration resulting from the sudden introduction of air into a confined
space containing oxygen-deficient products of incomplete combustion.
Backfire Flame Arrestor - ANSWER=A boat device that owners fail to keep clean, which is a
frequent cause of engine compartment fires on boats.
Ballast - ANSWER=A device on a fluorescent light fixture that transforms the voltage from
normal household voltage to a higher voltage.
