118 QUESTIONS AND ANSWERS
3.2.1* Approved. - ANSWER Acceptable to the authority having jurisdiction.
3.2.2* Code. - ANSWER A standard that is an extensive compilation of
provisions covering broad subject matter or that is suitable for adoption into law
independently of other codes and standards.
3.2.3* Guide. - ANSWER A document that is advisory or informative and that
contains only non-mandatory provisions. A guide may contain mandatory
statements such as when a guide can be used, but the document as a whole is
not suitable for adoption into law.
3.2.4* Recommended Practice. - ANSWER A document that is similar in content
and structure to a code or standard but that contains only non-mandatory
provisions using the word "should" to indicate recommendations in the body of
the text.
3.3.1* Absolute Temperature. - ANSWER A temperature measured in Kelvins
(K) or Rankines (R).
3.3.2 Accelerant. - ANSWER A fuel or oxidizer, often an ignitible liquid,
intentionally used to initiate a fire or increase the rate of growth or spread of
fire.
3.3.3 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.
, 3.3.4 Active Fire Protection System. - ANSWER A system that uses moving
mechanical or electrical parts to achieve a fire protection goal.
3.3.6 Ampacity. - ANSWER The maximum current, in amperes, that a
conductor can carry continuously under the conditions of use without exceeding
its temperature rating. [70, Article 100]
3.3.7 Ampere. - ANSWER The unit of electric current that is equivalent to a
flow of one coulomb per second; one coulomb is defined as 6.24 × 1018
electrons.
3.3.10 Arc Site. - ANSWER The location on a conductor with localized damage
that resulted from an electrical arc.
3.3.11 Arcing Through Char. - ANSWER Arcing associated with a matrix of
charred material (e.g., charred conductor insulation) that acts as a
semiconductive medium.
3.3.12 Area of Origin. - ANSWER 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. (See also 3.3.142, Point of
Origin.)
3.3.8 Arc. - ANSWER A high-temperature luminous electric discharge across a
gap or through a medium such as charred insulation.
3.3.9 Arc Mapping. - ANSWER 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.
3.3.13 Arrow Pattern. - ANSWER A fire pattern displayed on the cross section
of a burned wooden structural member.
