130 Exam Questions And Answers ||
Verified
\.How many feet are in a chain? - Answer-66 feet
\.Name the 3 sides of the fire triangle: - Answer-1) Oxygen
2) Fuel
3) Heat
\.How does conduction supply heat to a fuel to start a fire? - Answer-Conduction transfers heat
to adjacent fuels.via DIRECT CONTACT.
\.How does radiation supply heat to a fuel to start a fire? - Answer-Radiation transfers heat to
fuels through heat waves and rays.
\.How does convection supply heat to a fuel to start a fire? - Answer-Convection transfers heat
to fuels through indirect heating/cooling via wind/smoke.
\.Explain the reason for establishing an anchor point. - Answer-Creates an advantageous and
safe point of origin to flank the fire by establishing control lines.
\.What types of fuels might we find on the NORTH ASPECT? - Answer-Heavier fuels,
lower temperatures,
increased humidity,
wetter soil, and
, increased fuel moisture
\.What types of fuels might we find on the SOUTH ASPECT? - Answer-Lighter fuels,
increased temperatures,
decreased humidity,
dryer soil, and
decreased fuel moisture
\.Describe how a slope can affect a fire's rate of spread. - Answer-Convected heat rises, and in
conjunction with radiant heat, fuels upslope from the fire dry out rapidly and combust at a
much greater rate than horizontal or downslope spread. Badness.
\._____ bulb measures the ambient air temperature, and _____ bulb measures evaporation
rates to gauge relative humidity (RH). - Answer-Dry
Wet
\.Explain the inverse relationship between temperature and relative humidity (RH). - Answer-
When temperature increases, relative humidity decreases.
When temperature decreases, relative humidity increases.
\.What direction is wind coming from in a north wind? - Answer-North, moving south.
\.Describe the effect an incoming cold front might have on fire behavior. - Answer-A cold front is
the boundary line between 2 different air masses, with cooler air behind the frontal warmer air
mass. The differing air masses cause pressure differences that move into a region and can
generate moderate to strong wind speeds.
