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