b.False
true
Heat transfer to another body or within a body by direct contact is called:
a.Conduction.
b.Convection.
c.Radiation.
d.Pyrolysis.
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
true
In pre-flashover conditions the primary heat transfer mechanism for fire spread through a
The compartment is radiation.
a.True
b.False
false
In a compartment, flashover occurs because convective heat energy raises combustion to their auto-
ignition temperature.
a.True
b.False
false
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 they
maintain their structural integrity during the fire. Therefore, the fire investigator should consider the type of
