NAFI CFEI Exam Questions with100% Correct
Answers
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.
