S-290 Chapter 3
Three fuel factors the Fire line personal must monitor - answer Fuel characteristics.
Fuel moisture.
Fuel temperature.
What type of fuel has the best opportunity for running crown fire? - answer Close
canopy stands that are greater than 6 feet in height.
Four fuel groups - answer Grass.
Shrub.
Slash.
Timber litter.
Four classes of dead fuels. - answer Grasses/letter - zero 1/4 inch in diameter.
Twigs and small Stems - 1/4 inch to 1 inch in diameter.
Branches - 1 inch to 3 inches in diameter.
Large stems, branches - 3 inches to 8 inches in diameter.
Fuels that are closely compacted. - answer Have less surface area. Restrict oxygen.
Inhibit convective and radiant heat transfer. Have a slower rate of spread.
Horizontal continuity - answerHorizontal continuity is the horizontal distribution of fuels
at various levels were planes.
Vertical arrangement - answerFuels above ground and their vertical continuity, which
influences fire reaching various levels or vegetation Strata.
Chemical content - answerOr feels, living or dead, contain fiber that is known as
cellulose.
Four types of chemical conference - answerWax.
Oils.
Residence.
Pitch.
Six primary fire behavior characteristics involved with the rate of spread -
answerSpread.
Spotting.
Ignition.
Intensity.
Torching.
Crowning.
