Probable cause is not needed to obtain an administrative search warrant.
a.True
b.False correct answers true
Heat transfer to another body or within a body by direct contact is called:
a.Conduction.
b.Convection.
c.Radiation.
d.Pyrolysis. correct answers conduction
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 correct answers true
In pre-flashover conditions the primary heat transfer mechanism for fire spread through a
compartment is radiation.
a.True
b.False correct answers false
In a compartment, flashover occurs because convective heat energy raises combustible to their
auto-ignition temperature.
a.True
b.False correct answers false
, Combustion may continue with available oxygen concentrations lower than 1 percent.
a.True
b.False correct answers 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 correct answers true
Materials which have been properly treated with flame-retardants will not undergo pyrolysis
andfor this reason will not ignite.
a.True
b.False correct answers false
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 correct answers empirical
Inductive reasoning is when all available empirical data is analyzed using the investigator's
experience, training, knowledge and expertise.
