Question 27

If an elevated feature affords a good sight line,

Answer 27

take advantage of it as long as there is no remote possibility that the fire will go there.

Question 28

What are the purposes of recon at a wildland incident?

Answer 28

To define the principal hazard, judge the potential for environmental change (integrity), define the impact of the physical surrounding, and equate the exposure of crews to the environment and principal hazard.

Question 29

The principal hazard in most wildland environments can result from one of three causes:

Answer 29

- rapid fire spread - traffic issues - physical exertion
