of a and attention to all relevant details a systematic: a
systematic approach c . methodology approach d . g b . approximation approacheneral approach - ANSWER - a .
systematic approach
2. Absolute Temperature: Absolute A temperature measured in Kelvins ( K ) or Rankines ( R ) .
3. Accelerant: A fuel or oxidizer , often an ignitible liquid , intentionally used to initiate a fire or increase the rate
of growth or spread of fire .
4. 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 .
5. Active Fire Protection System: A system that uses moving mechanical or electrical parts to achieve
a fire protection goal .
6. Ambient: Someone's or something's surroundings , especially as they pertain to the local environment ; for
example , ambient air and ambient temperature .
7. Ampacity: The maximum current , in amperes , that a conductor can carry continuously under the conditions
of use without exceeding its temperature rating .
8. 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 .
9. Arc: A high - temperature luminous electric discharge across a gap or through a medium such as charred
insulation .
10. 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 .
11. Arc Site: The location on a conductor with localized damage that resulted from an electrical arc .
12. Arcing Through Char: Arcing associated with a matrix of charred material ( e.g. , charred conductor
insulation ) that acts as a semiconductive medium .
13. 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 .
14. Arrow Pattern: A fire pattern displayed on the cross - section of a burned wooden structural member
15. Arson: The crime of maliciously and intentionally , or recklessly , starting a fire . or causing an explosion .
16. Autoignition: Initiation of combustion by heat but without a spark or flame .
