NAFI CFEI Exam Questions with Correct Answers | 100% Verified solutions
Probable cause is not needed to obtain an administrative search warrant.
a.True
b.False ÇÇtrue
Heat transfer to another body or within a body by direct contact is called:
a.Conduction.
b.Convection.
c.Radiation.
d.Pyrolysis. ÇÇconduction
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 ÇÇtrue
In pre-flashover conditions the primary heat transfer mechanism for fire spread through a
compartment is radiation.
a.True
b.False ÇÇfalse
, In a compartment, flashover occurs because convective heat energy raises combustible to their
auto-ignition temperature.
a.True
b.False ÇÇfalse
Combustion may continue with available oxygen concentrations lower than 1 percent.
a.True
b.False ÇÇtrue
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 ÇÇtrue
Materials which have been properly treated with flame-retardants will not undergo pyrolysis
andfor this reason will not ignite.
a.True
b.False ÇÇfalse
Data that is based on observation or experience and can be verified is called:
