NAFI CFEI TESTThe basic methodology of the fire investigation should rely on the use of a
___________ and attention to all relevant details.
Systematic approach
With few exceptions, the proper methodology for a fire or explosion investigation
is to first______________then investigate the cause, circumstances, conditions,
or agencies that brought the ignition sources, fuel, and oxidant together
determine and establish origin(s)
The process of deterring the origin, cause, development, and responsibility as well
as the failure analysis of a fire or explosion is the definition of ________.
fire analysis
The process of determining the origin, cause, and responsibility for a fire or
explosions is_______.
fire investigation
The ________ is a systematic pursuit of knowledge involving the recognition and
formulation of a problem, the collection of data through observation and
experiment, and the formulation and testing of a hypothesis.

Absolute Temperature
Absolute A temperature measured in Kelvins ( K ) or Rankines ( R ) .
Accelerant

Ambient
Someone's or something's surroundings , especially as they pertain to the local
environment ; for example , ambient air and ambient temperature .
Ampacity
The maximum current , in amperes , that a conductor can carry continuously
under the conditions of use without exceeding its temperature rating .
Ampere
The unit of electric current that is equivalent to a flow of one coulomb per second
; one coulomb is defined as 6.24 x 10 ^ 18 electrons .
Arc
A high - temperature luminous electric discharge across a gap or through a
medium such as charred insulation .
Arc Mapping
The systematic evaluation of the electrical circuit configuration spatial
relationship of the circuit components , and identification of electrical arc sites to
assist in the identification of the area of origin and analysis of the fire's spread .
, Arc Site
The location on a conductor with localized damage that resulted from an
electrical arc .
Arcing Through Char
Arcing associated with a matrix of charred material ( e.g. , charred conductor
insulation ) that acts as a semiconductive medium .
Area of Origin
A structure , part of a structure , or general geographic location within a fire scene
, in which the " point of origin " of a fire or explosion is reasonably believed to be
located .
Arrow Pattern
A fire pattern displayed on the cross - section of a burned wooden structural
member
Arson
The crime of maliciously and intentionally , or recklessly , starting a fire . or
causing an explosion .
Autoignition
Initiation of combustion by heat but without a spark or flame .
