1.WILDLAND FIREFIGHTING S-190
Origin - ANSWER Where the fire started and or where it's going.
Head - ANSWER Greatest rate of spread. Moves intensely. May have more than one
head.
Fingers - ANSWER Long narrow strips of fire that break off of the main fire. Caused by
mixed fuels, natural features dividing the fire.
Pocket - ANSWER Unaffected area between the main fire and finger.
Perimeter - ANSWER Outer boundary of burning or burnt area.
Rear/ heel - ANSWER Opposite to the head of the fire. Close to the point of origin.
Flanks - ANSWER Sides of a wildland fire. May change to the head or fingers might form
because of fuel.
Islands - ANSWER Unburned areas inside the perimeter.
Wildland fires - ANSWER Unplanned or unwanted fires.
,Fireline - ANSWER Part of the control line. Dug to mineral soil. Where firefighting
activities take place.
Spot fires - ANSWER Smalls fires burning beyond main fire boundary.
Convection column - ANSWER Rising hot air/ gas above the fire source.
Slopover/ Breakover - ANSWER When fire crosses a control line
The green - ANSWER Unburned area close to the fire where live or dead fuels are. NOT
SAFE
Live fuels - ANSWER Living plants, high moisture vegetation, low moisture content
Dead fuels - ANSWER Where moisture is only governed by only atmospheric moisture.
Ie: relative humidity and precipitation.
The Black - ANSWER Area where fire has already moved through.
Surface/ Ground Fuel - ANSWER Fuel that contacts the ground. Ex: leafs, dead
branches, bark, tree cones.
Aerial fuels - ANSWER Fuel suspended from the ground. Ex: branches, twigs, bark and
vines.
Slope aspect - ANSWER NESW
North facing slopes - ANSWER More shade. Heavier fuels, low temp, high humidity,
high fuel moisture. Less fire activity than south.
, East facing slope - ANSWER Early heating in the morning. Early cooling in evening.
West facing slope - ANSWER Later heating and cooling within the day. Sunrise and
sunset
South facing slope - ANSWER Most hot slope. Results in high temp, low humidity, loss
of fuel and soil moisture, dry fuel like grass. More susceptible to fires than north slopes.
Slope - ANSWER Bad: uphill. Pre heats fuel and burns faster. Good: uphill moving
down. Doesn't preheat fuel and moves slower.
Chute - ANSWER Steep v shape drainage
Box canyons - ANSWER Chimney effect on a canyon
Narrow canyons - ANSWER Spread to the other side by radiation and spotting.
Wide canyons - ANSWER Not common for spotting but will occur on N S facing aspects
Natural barriers - ANSWER Rivers lakes rocks burned area swamps
Man made barriers - ANSWER Roads highways reservoirs firelines
Fuel position - ANSWER Helps firefighters predict how the fire will behave
Fuel moisture - ANSWER Helps firefighters predict how the fire will behave
