AND CORRECT DETAILED ANSWERS
3 Sides of Fire Triangle - (answer) Heat - Oxygen - Fuel
Without one!... Fire goes out!
3 Methods of heat transfer - (answer) Radiation - Conduction - Convection
Head of Fire - (answer) The part of a fire's perimeter that is roughly parallel to the main direction of
spread
Fingers of a fire - (answer) Extension of main fire - the long narrow extensions of a fire projecting from
the main body
Spot Fire - (answer) Beyond the main fire - Fire ignited outside the perimeter of the main fire by a
firebrand
Smoldering - (answer) Fire burning without a flame and barely spreading
Creeping Fire - (answer) Fire burning with a low flame and spreading slowly
Running Fire - (answer) Behavior of a fire spreading rapidly with a well defined head
Controlled - (answer) Fire can reasonably be expected to hold under the foreseeable conditions

canopy
Fuel Moisture - (answer) The amount of water in a fuel, expressed as a percentage of the oven-dry
weight of that fuel
Control vs. containment - (answer) control-
crews begin mop up
anchor point is established
fire is expected to hold in the conditions
fireline all around fire
containment-
