Answer

Question 2

A firefighter notices that smoke is beginning to fill a safety zone they are sheltering in. What does this indicate?

Accepted Answer

The safety zone may be compromised and repositioning or deployment of fire shelters may be needed

Answer

A dynamic safety zone is one that moves with the crew as they work, such as a section of black (burned) area adjacent to the crew's current position.

Accepted Answer

4 acres with 200-foot separation

Answer

NWCG guidance recommends approximately 4 acres for a 20-person crew with 50-foot flame lengths, requiring about 200 feet of separation from the fuel.

Question 5

A safety zone located in a rocky outcrop on a ridgeline is considered most effective under which condition?

When it is free of fine fuels and offers rocky, non-combustible ground
