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

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
