Verifeid and Updated
Probable cause is not needed to obtain an administrative search warrant.
a.True
b.False
ANS : A
Heat transfer to another body or within a body by direct contact is called:
a.Conduction.
b.Convection.
c.Radiation.
d.Pyrolysis.
ANS : A
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
ANS : A
In pre-flashover conditions the primary heat transfer mechanism for fire spread
through a
compartment is radiation.
a.True
b.False
,ANS : B
In a compartment, flashover occurs because convective heat energy raises
combustible to their auto-ignition temperature.
a.True
b.False
ANS : B
Combustion may continue with available oxygen concentrations lower than 1
percent.
a.True
b.False
ANS :A
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
ANS : A
Materials which have been properly treated with flame-retardants will not
undergo pyrolysis andfor this reason will not ignite.
a.True
b.False
ANS : B
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 data
ANS : B
Inductive reasoning is when all available empirical data is analyzed using the
investigator's experience, training, knowledge and expertise.
a.True
b.False
ANS : A
deductive reasoning
Testing of a hypothesis by comparing the investigators hypothesis to all known
facts is using____________ reasoning.
a.Deductive
b.Inductive
c.Both A and B
d.Neither A or B
ANS : A
Which of the following can be defined as a fuel gas?
a.Natural gas
b.Liquefied petroleum gas
c.Manufactured gases
d. all of the above
ANS : D
Prior to conducting an on scene investigation many things should be identified,
including:
a.Date and time of incident
b.Size and complexity of the incident
c.Purpose of the investigation
d.All of the above
ANS : D
