NAFI CFEI questions with verified
answers already passed
true - correct answer ✔✔Probable cause is not needed to obtain an administrative search
warrant.
a.True
b.False
conduction - correct answer ✔✔Heat transfer to another body or within a body by direct
contact is called:
a.Conduction.
b.Convection.
c.Radiation.
d.Pyrolysis.
true - correct answer ✔✔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 - correct answer ✔✔In pre-flashover conditions the primary heat transfer mechanism for
fire spread through a
compartment is radiation.
a.True
b.False
, false - correct answer ✔✔In a compartment, flashover occurs because convective heat energy
raises combustible to their auto-ignition temperature.
a.True
b.False
true - correct answer ✔✔Combustion may continue with available oxygen concentrations lower
than 1 percent.
a.True
b.False
true - correct answer ✔✔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 - correct answer ✔✔Materials which have been properly treated with flame-retardants
will not undergo pyrolysis andfor this reason will not ignite.
a.True
b.False
empirical - correct answer ✔✔Data that is based on observation or experience and can be
verified is called:
a.Anecdotal data
b.Empirical data
c.Qualitative data
