NAFI CFEI EXAM LATEST UPDATE 2023-2024 ALREADY
GRADED A 100% CORRECT
true - ANSWER>>Probable cause is not needed to obtain an administrative search
warrant. a.True
b.False
conduction - ANSWER>>Heat transfer to another body or within a body by direct
contact is called:
a.Conduction.
b.Convection.
c.Radiation.
d.Pyrolysis.
true - 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.Fals
e
false - ANSWER>>In pre-flashover conditions the primary heat transfer mechanism
for fire spread through a
compartment is radiation.
a.True
b. False
false - ANSWER>>In a compartment, flashover occurs because convective heat energy
raises combustible to their auto-ignition temperature.
, a. True
b.Fals
e
true - ANSWER>>Combustion may continue with available oxygen concentrations lower
than 1 percent.
a. True
b.Fals
e
true - 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.Fals
e
false - ANSWER>>Materials which have been properly treated with flame-retardants
will not undergo pyrolysis andfor this reason will not ignite.
a. True
b.Fals
e
empirical - ANSWER>>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
