<LATEST VERSION>
1. Wildland Fire - ANSWER ✔ Unplanned and unwanted fire requiring
suppression action; an uncontrolled fire, usually spreading through
vegetative fuels. These fires can threaten structures or other improvements
2. Fire Behavior - ANSWER ✔ Manner in which a fire reacts to the variables
of fuel, weather, and topography
3. Topography - ANSWER ✔ Land surface configuration
4. Crew - ANSWER ✔ Organized group of firefighters under the leadership of
a crew leader or other designated supervisor; sometimes referred to as a
"company" in municipal departments
5. Aspect - ANSWER ✔ Compass direction toward which a slope faces
6. Slope - ANSWER ✔ - Natural or artificial topographic incline; degree of
deviation from horizontal
- fires typically move faster going uphill than downhill
, - flames are closer to the fuel dehydrating, preheating, and igniting
them sooner
- wind currents normally move uphill during the day and tend to push
heat and flames toward new fuels
- upslope fires create a draft, increasing the ROS
7. T/F
Topography can directly and indirectly affect fuels and their availability for
combustion - ANSWER ✔ True
8. Of the three environmental factors that influence fire behavior, which is the
least variable - ANSWER ✔ topography
9. What are the 3 Environmental Factors that influence Fire Behavior? -
ANSWER ✔ 1) Weather
2) Topography
3) Fuels
10.The least critical form of heat transfer that influences rate of spread in a
running wildland fire is. - ANSWER ✔ Conduction
11.The point to which a combustible material must be heated to produce self
sustaining combustion is known as the - ANSWER ✔ Ignition temperature
12.What factors primarily affect fireline intensity? - ANSWER ✔ Fuel size
Fuel moisture
Fuel temperature
Fuel compactness and arrangement
, ALL OF THE ABOVE
13.T/F
Two requirements for long range spotting are wind and a well developed
convection column. - ANSWER ✔ True
14.The fuel moisture at which fire will not spread is the - ANSWER ✔
Moisture of extinction
15.Inputs used to determine fine dead fuel moisture content are - ANSWER ✔
Time of day, month of year, dry bulb temperature, relative humidity, aspect,
percent slope, shading of surface fuels
16.T/F
Only 1000 hour timelag fuel moisture is used when making wildland fire
behavior predictions - ANSWER ✔ False
17.Select the fuel that would reach its moisture of extinction first during
nighttime humidity recovery - ANSWER ✔ Cured cheatgrass
18.If the wet bulb is not read at its lowest point, what will happen - ANSWER
✔ The calculated relative humidity will be too high
19.three components of Wildlands fire environment - ANSWER ✔ weather
topography
, fuels
20.living fuels four categories - ANSWER ✔ herbaceous- perennial,annual
woody- evergreen, deciduous
21.weather factors in wf - ANSWER ✔ temperature
rh
atmosphere stability
precipitation
wind/direction
22.topography factor's wf behavior - ANSWER ✔ position on slope
aspect
shape of country
steepness of slope
elevation
23.fuel factors in wf behavior - ANSWER ✔ fuel loading
size and shape
compactness
horizontal continuity
vertical continuity
chemical content
24.What should you ALWAYS do when collecting weather observations?
(Select all that apply) - ANSWER ✔ Acclimate your weather instruments in
the shade.
Take weather observations in a safe location.
