What is the "rear" or "heel" of a fire? - ANSWERSIt is the end opposite the head .
Therefore it is relatively closer to the point of origin than to the head.
Because the fire at the, (blank), burns into any prevailing wind, it generally burns with
low intensity and has a low ROS. - ANSWERSHeel
What are "flanks" on a fire? - ANSWERSFlanks are the sides of a wildland fire, roughly
parallel to the main direction of fire spread.
Why is it important to control flanks of a fire ASAP? - ANSWERSBecause:
, 1. A shift in wind direction may quickly change a flank into a head.
2. Fingers often extend from flanks
What are "islands" in a fire? - ANSWERSIslands are unburned areas inside the fire
perimeter. Since islands are unburned potential fuels, patrol them frequently & check for
spot fires.
Islands close to a, (blank), line may flare up later & start spot fire across the control line.
Therefore you may want to burn them out. - ANSWERSControl line
When does a "slopover" occur? - ANSWERSA slopover occurs when fire crosses a
control line or natural barrier intended to contain the fire,
Note: A slopover occurs immediately across & adjacent to the control line whereas spot
fires occur some distance from the control line.
What is the "green"? - ANSWERSThe green is ANY area that is NOT BURNT but is
adjacent to an involved area.

As a rule of thumb, there 60 minutes in an hours and just over, (blank), feet in a chain. -
ANSWERS60 feet
1 feet per minute equals, (blank), chains per hour - ANSWERS1 Chain
10 feet per minute equals, (blank), chains per hour - ANSWERS10 Chains
Fire Spread is the same thing as, (blank) - ANSWERSRate of Spread (ROS)
(Blank), fires burn without a flame and very low ROS. - ANSWERSSmoldering
(Blank), fires burn with a low flame and low ROS. - ANSWERSCreeping
A, (blank), fire is one that spreads rapidly with a well-defined head. -
ANSWERSRunning
What is a backing fire? - ANSWERSA backing fire is where the fire moves AWAY from
