Correct Answers
Origin— Correct Answer: The location where the fire
started
Head— Correct Answer: The hottest and most active
part of the fire. Shows the direction in which the fire is
burning
Flank— Correct Answer: May have active fire, but not as
hot as the head of the fire. Parallel to the main direction
of spread
Rear/heel— Correct Answer: Opposite the head of the
fire and burning less vigorously, if at all. Often near the
fire origin.
Perimeter— Correct Answer: Boundary line of the fire.
May not have active fire on some portions.
Finger— Correct Answer: A narrow strip that burns away
from the main part of the fire. Can be dangerous if fire
personnel are flanked by a finger.
,Pocket— Correct Answer: The unburned area between
the main fire and any fingers.
Island— Correct Answer: Area of unburned fuel inside
the fire perimeter
Spot fire— Correct Answer: Burning area outside the
main fire perimeter, often caused by wind blown
embers or rolling debris.
Spread— Correct Answer: Movement of the fire. Rate of
spread (ROS) is given in chains per hour.
Smoldering— Correct Answer: Fire burning without flame
and barely spreading
Creeping— Correct Answer: Fire burning with a low
flame and spreading slowly
Running— Correct Answer: fire spreading rapidly with a
well defined head
Backing— Correct Answer: Fire moving away from the
head, downhill, or against the wind
,Spotting— Correct Answer: Sparks or embers produced
by the main fire are carried by winds or convection
column.
Torching, candling, passive crown fire— Correct Answer:
Fire burning on the surface, but periodically igniting the
crown of a single or small group of trees before returning
to the surface.
Crowning— Correct Answer: High fire intensity and
forward ROS.
"Active/running/continuous": crowning remains
dependent on heat from surface fires
"Independent": fire burns canopy fuels without aid of
surface fire
Blowup— Correct Answer: A sudden increase in fire
intensity or rate of spread sufficient to prevent direct
control or to upset existing control plans
Control line— Correct Answer: All constructed or natural
barriers and treated fire edges used to contain a fire
(includes roads, rivers, AND dug line)
, Fireline— Correct Answer: The part of a containment or
control line that is scraped or dug to mineral soil (made
by a handcrew)
Anchor point— Correct Answer: An advantageous
location, usually a barrier to fire spread, from which to
start constructing a fireline. This is used to minimize the
chance of being flanked by the fire while the line is
being constructed.
Mopup— Correct Answer: Final extinguishment of a fire
after it is lined
Class of fire— Correct Answer: Classifies size of fire, class
A being the smallest, and class G being the largest
Personal gear weight limits— Correct Answer: Personal
gear weight=45 lbs, line/web gear weight=20 lbs, total
65 lbs
Mandatory PPE— Correct Answer: Helmet, eye pro, ear
pro, gloves, Nomex, boots/socks, fire shelter, water,
head lamp, personal gear pack (red pack), IRPG, fire
line handbook
