NAFI CFEI Exam 2023 Already Passed
true - Probable cause is not needed to obtain an administrative search warrant.
a.True
b.False
conduction - Heat transfer to another body or within a body by direct contact is called:
a.Conduction.
b.Convection.
c.Radiation.
d.Pyrolysis.
true - Fuses and circuit breakers provide protection against electrical short circuits, ground/earth faults,and load currents that might
be damaging (i.e. overloads) to the building electrical system.Properly functioning circuit protection may allow the elimination of the
buildings wiring system as a potential cause of the fire.
a.True
b.False
false - In pre-flashover conditions the primary heat transfer mechanism for fire spread through a
compartment is radiation.
a.True
b.False
false - In a compartment, flashover occurs because convective heat energy raises combustible to their auto-ignition temperature.
a.True
b.False
true - Combustion may continue with available oxygen concentrations lower than 1 percent.
a.True
b.False
true - The way structures react in a fire often influence how the fire grows and spreads as well as how theymaintain their structural
integrity during the fire. Therefore, the fire investigator should considerthe type of structure and method of construction when
completing the analysis of fire growth and spread as a part of their fire investigation.
a.True
b.False
false - Materials which have been properly treated with flame-retardants will not undergo pyrolysis andfor this reason will not ignite.
a.True
b.False
empirical - Data that is based on observation or experience and can be verified is called:
a.Anecdotal data
b.Empirical data
c.Qualitative data
d.Categorical data
true - Inductive reasoning is when all available empirical data is analyzed using the investigator's experience, training, knowledge
and expertise.
a.True
b.False
deductive reasoning - Testing of a hypothesis by comparing the investigators hypothesis to all known facts is using____________
reasoning.
a.Deductive
b.Inductive
c.Both A and B
d.Neither A or B
all of the above - Which of the following can be defined as a fuel gas?
a.Natural gas
b.Liquefied petroleum gas
c.Manufactured gases
d. all of the above
all of the above - Prior to conducting an on scene investigation many things should be identified, including:
a.Date and time of incident
b.Size and complexity of the incident
c.Purpose of the investigation
d.All of the above
true - Luminescent flame temperatures are dependant on the fuel to oxygen ratio.
a.True
b.False
timeline - The investigative tool used to graphically or in a narrative manner depict events relating to a fire or explosion in
chronological order is called:
a.Timeline
b.Systems analysis
c.Fault tree
d.Computer modeling
