The basic methodology of the fire investigation should rely on the use of
a______________________and attention to all relevant details a systematic
a systematic approach
b. approximation approach
c . methodology approach
d. General Approach - ANSWER - a . systematic approach
Absolute Temperature
Absolute A temperature measured in Kelvins ( K ) or Rankine ( R ) .
Accelerant
A fuel or oxidizer , often an ignitable liquid , intentionally used to initiate a fire or
increase the rate of growth or spread of fire .
Accident
,ANSWER An unplanned event that interrupts an activity and sometimes causes
injury or damage or a chance occurrence arising from unknown causes ; an
unexpected happening due to carelessness , ignorance , and the like .
Active Fire Protection System
A system that uses moving mechanical or electrical parts to achieve a fire
protection goal .
Active Fire Protection System
A system that uses moving mechanical or electrical parts to achieve a fire
protection goal .
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 .
Autoignition Temperature
The lowest temperature at which a combustible material ignites in air without a
spark or flame .
