Red Card Environmental Health & Safety 4 — Questions and Answers
Question 1: What is the purpose of the 'downhill line construction checklist' used on wildland fires?
- To ensure proper hand tool assignment before starting a line
- To evaluate whether it is safe to construct a fireline downhill, which presents unique rollout hazards (Correct answer)
- To document fuel types along the planned line route
- To authorize bulldozer use on steep terrain
Correct answer: To evaluate whether it is safe to construct a fireline downhill, which presents unique rollout hazards
Downhill line construction is a Watch Out Situation requiring a specific checklist because rolling debris, fire runs, and limited escape options create elevated risk.
Question 2: Which of the following is NOT one of the 18 Watch Out Situations?
- Unburned fuel between you and the fire
- Wind increases and/or changes direction
- You are resting and napping near the fireline during peak fire behavior hours (Correct answer)
- You are in country not seen in daylight
Correct answer: You are resting and napping near the fireline during peak fire behavior hours
Resting near the fireline is not listed among the 18 Watch Out Situations, though all the other choices are.
Question 3: When a crew is working in a canyon during active fire conditions, what is the primary safety concern related to terrain?
- Flooding from aerial retardant drops
- Chimney effect causing rapid fire acceleration upslope toward crew members (Correct answer)
- Increased radio dead zones blocking communication
- Soil erosion undermining crew footing
Correct answer: Chimney effect causing rapid fire acceleration upslope toward crew members
Canyons act as chimneys, dramatically accelerating fire upslope and trapping crews with limited escape options.
Question 4: What is the recommended action when a firefighter discovers an unmarked well or mine shaft while working in a wilderness area?
- Mark it with flagging tape and continue working
- Report it to the supervisor immediately and establish a hazard exclusion zone (Correct answer)
- Cover it with brush to prevent others from falling in
- Investigate depth before deciding if it is a hazard
Correct answer: Report it to the supervisor immediately and establish a hazard exclusion zone
Unmarked shafts are serious fall hazards and must be flagged, reported, and excluded from the work area immediately.
Question 5: During a burnout operation, which environmental factor most significantly increases risk to firefighters holding the black?
- Low relative humidity
- Spotting across the intended holding line due to high winds (Correct answer)
- Dry thunderstorm lightning activity
- Steep terrain above the holding line
Correct answer: Spotting across the intended holding line due to high winds
High winds can carry embers across the holding line, creating spots that can trap firefighters between two fire fronts.
Question 6: What is the correct procedure if a firefighter is exposed to hazardous materials (such as propane tanks or chemical storage) discovered within the fire perimeter?
- Remove the containers to a safe area outside the perimeter
- Immediately withdraw, report to the supervisor, and establish an exclusion zone (Correct answer)
- Douse the containers with water to prevent explosion
- Mark the location and continue suppression work at a distance
Correct answer: Immediately withdraw, report to the supervisor, and establish an exclusion zone
Firefighters are not hazmat technicians; the correct response is to withdraw, report the hazard, and let trained personnel handle it.
Question 7: Why is it important to check for overhead power lines before beginning aerial operations or raising tall equipment near a fire?
- Power lines can become entangled in helicopter blades during water drops
- Energized lines remain deadly even when obscured by smoke or vegetation and can arc to nearby personnel and equipment (Correct answer)
- Power companies charge incident management teams for line damage
- Lines can redirect air tanker drops unpredictably
Correct answer: Energized lines remain deadly even when obscured by smoke or vegetation and can arc to nearby personnel and equipment
Energized power lines can arc electricity to nearby personnel and equipment, causing electrocution, and are especially difficult to see in smoke.
