Correct Answers
Fire Behavior Correct Answer: manner in which a fire
reacts to the variables of fuel, weather, and topography
Origin Correct Answer: Area where the fire started. It's
also the point from which the fire spreads, depending on
the fuels present & the effects of wind and slope.
Protect the area of origin for subsequent investigation of
fire cause whenever possible.
Head Correct Answer: Part of wildland fire with the
greatest forward rate of spread (ROS). Normally either
on the edge of a fire opposite to the direction from
which wind is blowing or it's toward the upper part of a
slope. Burns intensely and fast. Large fires may have
multiple heads. You have to control the head(s) and
prevent new heads to suppress fire.
Fingers Correct Answer: Long, narrow strips of fire that
extend from the main body of a fire.
Pocket Correct Answer: Unburned area between the
main fire and any fingers.
, Perimeter Correct Answer: Outer boundary a.k.a fire
edge. Not the control line or fireline. Continues to grow
until controlled and extinguished.
Fireline Correct Answer: Part of control line that's
constructed by firefighters.
Control line Correct Answer: All constructed or natural
barriers and treated fire edges used to control a fire.
Rear Correct Answer: Or heel, is the end opposite the
head. Because fire at the heel usually burns into wind, it
generally burns with low intensity, has a low ROS, and is
generally easier to control than the head.
Flanks Correct Answer: Sides of a fire, roughly parallel to
the main direction of fire spread. Either left or right as
you are looking from the heel of a fire toward the head.
Control ASAP because fingers can extend and a shift in
wind can change it into a head.
Islands Correct Answer: Unburned areas inside fire
perimeter.
