(Solved) American Military University NAFI CFEI Questions and Answers LATEST Probable cause is not needed to obtain an administrative search warrant. Heat transfer to another body or within a b... ody by direct contact is called: 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. In pre-flashover conditions the primary heat transfer mechanism for fire spread through a compartment is radiation. In a compartment, flashover occurs because convective heat energy raises combustible to their auto-ignition temperature. Combustion may continue with available oxygen concentrations lower than 1 percent. 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. Materials which have been properly treated with flame-retardants will not undergo pyrolysis andfor this reason will not ignite. Data that is based on observation or experience and can be verified is called: Inductive reasoning is when all available empirical data is analyzed using the investigator's experience, training, knowledge and expertise. Testing of a hypothesis by comparing the investigators hypothesis to all known facts is using____________ reasoning. Which of the following can be defined as a fuel gas? Prior to conducting an on scene investigation many things should be identified, including: Luminescent flame temperatures are dependant on the fuel to oxygen ratio. The investigative tool used to graphically or in a narrative manner depict events relating to a fire or explosion in chronological order is called: 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: Protected areas result from an object or item prohibiting the products of combustion from depositingon materials which the object protects. A deflagration resulting from the sudden introduction of air into a confined space containing oxygendeficient products of incomplete combustion. What does the "V" in V-pattern represent? Which of the following is NOT one of the three elements of arson? A BLEVE is a type of explosion involving the ignition of a dispersed vapor cloud? Adequate debris removal is essential in an origin investigation? The court usually permits the fire and explosion investigator to refresh his memory from his noteswhile testifying in a deposition or trial? In a fire, the human body is completely consumed? Fire deaths can occur from: [Show More]
