S-290 PRACTICE EXAM 2026 SOLVED
QUESTIONS WITH FULL EXPLANATIONS
◉Select the statement that best describes the effect of slope
steepness on fuel availability. Answer: A fire starting at the base of
the slope has more fuel available for spread
◉A fuel model is described as. Answer: A set of numbers that define
fuel input for use in the surface fire spread model
◉The four fuel groups defined in the fire behavior prediction system
are. Answer: Grass, shrub, timber and logging slash
◉Available fuels are. Answer: All dead and live fuels that will ignite
and continue to burn
◉Fuel loading is. Answer: The oven dry weight of fuel in an given
area, expressed as tons/acre or pounds/acre
◉Fuel moisture content. Answer: The amount of water in fuel
expressed as a percent of the oven dry weight of that fuel
, ◉Fuel size and shape. Answer: The surface area to volume ratio
◉Fuel chemical content. Answer: The presence of volatile
substances in a fuel
◉Which of the following fuel characteristics affect all six wildland
fire behavior concerns, i.e. ignition, spread, intensity, spotting,
torching, and crowning. Answer: Moisture content

Answer: 0.0 to 1/4" in diameter
◉Fuel moisture timelag can best be defined as. Answer: The rate at
which dead fuel gains or loses moisture
◉One hour timelag fuel moisture is used in fire behavior
calculations to determine. Answer: Whether fine dead fuels are
available for ignition and fire spread
