WILDLAND FIRE S190 EXAM

ACTUAL EXAM WITH CORRECT SOLUTIONS.

When is a fire controlled? - correct answer- when control lines can reasonably be expected to hold under the forseesable conditions pg. 1.9

What are the components of the fire triangle? - correct answer-

1) Fuel: to burn

2) Air: oxygen for flame

3) Heat: to start and continue combustion process.

*remove any single one, there can be no fire* pg. 1.10

What are the 3 processes of heat transfer, which is most

important? - correct answer- 1) Radiation: dries surrounding

fuels and sometimes ignites them

2) Convection: occurs when lighter warm air moves upward

3) Conduction: heat transferred by from one fuel particle to

another

• convection is the most important while conduction is least

important because of woods low conduction rate*

Spotting - correct answer- process of convection starting new fires beyond the zone of direct ignition by main fire pg. 1.6

Running Fire - correct answer- fire spreading rapidly with a well defined head pg. 1.6

Smoldering - correct answer- also known as "punking around" is a fire with out flame and barely spreading pg. 1.6

Relative Humidity - correct answer- amount of moisture in the air divided by the amount of air held when saturated at the same air temperature *typically reaches its lowest point at mid to late afternoon (when temperature reaches its max)** pg. 2b.8

Horizontal Continuity - correct answer- 1) Uniform fuels: all

fuels distributed continuously over an area. (network of fuels providing continuous path of fire spread)
