DETAILED ANSWERS (VERIFIED ANSWERS)
ALREADY GRADED A+ BRAND NEW!!
Absolute Temperature - CORRECT ANSWER: a temperature measured in Kelvins (K)
or Rankines (R)
Accelerant - CORRECT ANSWER: a fuel or oxidizer intention used to initiate a fire or
increase its spread
Accidental Fire - CORRECT ANSWER: an unplanned fire or a chance occurrence
arising from unintentional circumstances
Active Fire Protection System - CORRECT ANSWER: a mechanical or electric system
that activates under fire circumstances (ex. detectors and sprinklers)
Ambient - CORRECT ANSWER: something/someones surrounding environment
Ampacity - CORRECT ANSWER: the maximum current in amperes that a conductor
can continuously carry without going over it's max temperature rating
Ampere - CORRECT ANSWER: a unit of electric current equivalent to 1 coulomb
(6.24x1018 electrons) per second
Approved - CORRECT ANSWER: acceptable
Arc - CORRECT ANSWER: a high-temperature, glowing electric particle (spark)
discharged across a circuit gap or through a fuel
,Arc Mapping - CORRECT ANSWER: evaluating circuit configurations for information
about what might have caused the fire
Arc Site - CORRECT ANSWER: the location on a conductor that receives damage from
arcing
Arcing through char - CORRECT ANSWER: when arcing is conducted through char
Area of Origin - CORRECT ANSWER: the geographic location of a fire scene in which
the point of origin is located
Arrow Pattern - CORRECT ANSWER: a fire pattern on the cross section of burned
wooden structural components, looks like a triangle with the bottom being most burned
out and the top being least burned out
Arson - CORRECT ANSWER: the crime of maliciously or intentionally starting a fire or
explosion
Autoignition - CORRECT ANSWER: heated combustion without a spark or flame
Autoignition Temperature - CORRECT ANSWER: lowest temperature that a material
can start ignition spontaneously
Backdraft/Smoke Explosion - CORRECT ANSWER: a deflagration explosion caused by
adding oxidation to an oxygen deficient fire
Bead - CORRECT ANSWER: a blob of re-solidified metal that was melted by arcing at
the end of circuit conductor remains
, Blast Pressure Front - CORRECT ANSWER: the high pressure leading edge of
explosion that causes damage by pushing out and displacing the normal ambient
pressure
BLEVE - CORRECT ANSWER: Boiling Liquid Expanding Vapor Explosion
Bonding - CORRECT ANSWER: the permanent joining of metal parts that creates a
conductive and continuous (safe) path for electrical currents
British Thermal Unit (BTU) - CORRECT ANSWER: a unit of energy, 1055 joules of
energy
Calcination of Gypsum - CORRECT ANSWER: the release of chemically bound water
from gypsum by fire that results in a pattern (looks like different levels of normal wall
burn damage, see fire patterns section)
Calorie - CORRECT ANSWER: a unit of energy, 4.184 joules of energy
Cause - CORRECT ANSWER: the circumstances, conditions and agents that brought
about a fire or explosion and its affects
Ceiling jet/Ceiling layer/Upper layer - CORRECT ANSWER: : the thin layer of hot gases
that forms in the top of a room as a result of convective heat pushing up
Char - CORRECT ANSWER: carbon material that has been burned to the point of
blackening
Char blisters - CORRECT ANSWER: the alligator skin looking pattern/cracks on burned
carbon materials
