NAFI CFEI 100% VERIFIED SOLUTIONS REVISED 2023//2024 Probable cause is not needed to obtain an administrative search warrant. a.True b.False - ANSWER true Heat transfer to another body or within a body by direct contact is called: a.Conduction. b.Convection. c.Radiation. d.Pyrolysis. - ANSWER 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 - ANSWER true In pre-flashover conditions the primary heat transfer mechanism for fire spread through a compartment is radiation. a.True b.False - ANSWER false In a compartment, flashover occurs because convective heat energy raises combustible to their auto-ignition temperature. a.True b.False - ANSWER false Combustion may continue with available oxygen concentrations lower than 1 percent. a.True b.False - ANSWER 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 - ANSWER true Materials which have been properly treated with flame-retardants will not undergo pyrolysis andfor this reason will not ignite. a.True b.False - ANSWER 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 - ANSWER empirical Inductive reasoning is when
