true - ✔✔Probable cause is not needed to obtain an administrative search warrant.
a.True
b.False
conduction - ✔✔Heat transfer to another body or within a body by direct contact is called:
a.Conduction.
b.Convection.
c.Radiation.
d.Pyrolysis.
true - ✔✔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.

true - ✔✔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 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 - ✔✔Materials which have been properly treated with flame-retardants will not undergo pyrolysis andfor this reason will not ignite. a.True b.False empirical - ✔✔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 true - ✔✔Inductive reasoning is when all available empirical data is analyzed using the investigator's experience, training, knowledge and expertise. a.True b.False deductive reasoning - ✔✔Testing of a hypothesis by comparing the investigators hypothesis to all known facts is using____________ reasoning.

Fault tree - ✔✔A diagram that places, in a logical sequence, the conditions and chains of events that are necessaryfor a fire or explosion to occur is called: a.Timeline b.Systems analysis c.Fault tree d.Computer modeling true - ✔✔Protected areas result from an object or item prohibiting the products of combustion from depositingon materials which the object protects. a.True b.False backdraft - ✔✔A deflagration resulting from the sudden introduction of air into a confined space containing oxygendeficient products of incomplete combustion. a.Flashover b.Flameover c.Smoke Explosion d.Backdraft the geometric shape of the pattern - ✔✔What does the "V" in V-pattern represent? a.Vector - pattern b.Virtual - pattern c.The geometric shape of the pattern d.Represents the name of the first individual who recognized the pattern There is a gasoline pattern found on the premises - ✔✔Which of the following is NOT one of the three elements of arson? a.There has been burning of property b.The burning is incendiary in origin c.The burning is shown to be started with malice with the intent of destroying property

d.There is a gasoline can found on the premises false - ✔✔A BLEVE is a type of explosion involving the ignition of a dispersed vapor cloud? a.True b.False true - ✔✔Adequate debris removal is essential in an origin investigation? a.True b.False true - ✔✔The court usually permits the fire and explosion investigator to refresh his memory from his noteswhile testifying in a deposition or trial? a.True b.False false - ✔✔In a fire, the human body is completely consumed? a.True b.False all of the above - ✔✔Fire deaths can occur from: a.Inhalation of hot gases b.Inhalation of toxic gases c.Thermal Burns d.All of the Above
