When a crew is caught in a rapidly changing fire situation and must deploy fire shelters, they should deploy in:
Answer: An open area, lying face down with feet toward the fire, spread apart
Firefighters should deploy in an open area, lying face down with feet toward the fire, and spread apart to minimize heat transfer between shelters.
In the context of wildland fire operations, what does the term 'progressive hose lay' mean?
Answer: A hose lay that advances toward the fire as water supply is extended
A progressive hose lay extends incrementally toward the fire, adding hose sections and lateral lines as suppression advances.
Which hand signal is used to communicate 'stop' or 'hold' when working near noisy equipment or in smoke?
Answer: Closed fist raised overhead
A closed fist raised overhead is the standard wildland fire hand signal for 'stop' or 'hold' operations.
During initial attack, the most critical factor in determining whether direct attack is appropriate is:
Answer: Whether firefighters can work safely at the fire's edge given current behavior
Direct attack is only appropriate when current fire behavior allows crews to safely work at the fire's edge without unacceptable risk.
A retardant line dropped by an air tanker is most effective when used as:
Answer: A delay tactic to slow fire spread until ground crews can construct a fireline
Aerial retardant slows fire spread and gives ground crews time to construct a fireline, but it must be reinforced to be effective.
What is the primary hazard associated with fighting fire in a narrow canyon or drainage?
Answer: Chimney effect channeling fire rapidly upslope with little warning
Narrow canyons act as chimneys, channeling heated air and fire gases upward very rapidly, creating extreme and sudden fire behavior.
When a crew completes fireline construction and transitions to mop-up, the standard depth for mop-up from the fire's edge is typically:
Answer: 50–100 feet or as specified in the incident action plan
Standard mop-up depth is typically 50–100 feet from the control line, or as specified in the IAP, to prevent escapes.
