NAFI CFEI EXAM QUESTIONS AND ANSWERS 2025
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
