Red Card Hazard Identification & Assessment 4 — Questions and Answers
Question 1: Which of the 18 Watch Out Situations involves working on a fire with unresolved line construction ahead?
- Watch Out #3: You are in country not seen in daylight
- Watch Out #14: Attempting frontal assault on fire
- Watch Out #6: Constructing line without safe anchor point
- Watch Out #11: Unburned fuel between you and the fire (Correct answer)
Correct answer: Watch Out #11: Unburned fuel between you and the fire
Watch Out Situation #11 warns against unburned fuel between you and the fire, as that fuel can ignite and cut off your position without warning.
Question 2: How does relative humidity (RH) below 15% affect wildland fire hazard?
- It reduces fire risk by making fuels denser
- It indicates critically dry conditions that increase ignition potential and rate of spread (Correct answer)
- It has minimal effect if wind speeds are low
- It primarily affects large timber fuels, not fine fuels
Correct answer: It indicates critically dry conditions that increase ignition potential and rate of spread
RH below 15% is a key threshold for critical fire weather; fuels cure rapidly, ignition is easier, and fire spreads aggressively in all fuel types.
Question 3: A firefighter smells burning pitch and sees resin boiling on tree trunks near the fire. What does this indicate?
- The fire is losing intensity
- Extreme heat is being generated, indicating potential for crown fire torching (Correct answer)
- Retardant is chemically reacting with tree sap
- The trees are not a significant fire hazard in this condition
Correct answer: Extreme heat is being generated, indicating potential for crown fire torching
Boiling resin and intense pitch smell indicate trees are being subjected to extreme radiant heat, a precursor to individual tree torching and potential crown fire spread.
Question 4: What is the primary purpose of a Safety Zone in wildland firefighting?
- A pre-designated area where firefighters can safely deploy fire shelters or survive without shelter (Correct answer)
- A staging area for equipment and supply drops
- A location where firefighters gather for morning briefings
- An area cleared for helicopter landing zones
Correct answer: A pre-designated area where firefighters can safely deploy fire shelters or survive without shelter
A Safety Zone is an area large enough and clear enough of fuels that firefighters can survive a fire passage without deploying fire shelters, providing the last line of defense.
Question 5: During hazard assessment, which combination of factors represents the most dangerous fire weather scenario?
- Low wind, high humidity, overcast skies
- High temperature, low humidity, strong erratic winds (Correct answer)
- Morning calm, moderate humidity, light fuel load
- Offshore breeze, high humidity, scattered thunderstorms
Correct answer: High temperature, low humidity, strong erratic winds
High temperature combined with low humidity dries fuels rapidly, and strong erratic winds drive fast-moving, unpredictable fire spread — the classic extreme fire weather combination.
Question 6: What hazard does 'squirrelly' or erratic wind behavior present on a wildland fire?
- Reduced visibility makes it harder to spot the fire
- Unpredictable wind shifts can cause rapid changes in fire direction, trapping crews (Correct answer)
- Erratic winds reduce spotting distance from the main fire
- Wind variability slows overall fire spread
Correct answer: Unpredictable wind shifts can cause rapid changes in fire direction, trapping crews
Erratic winds create sudden, unpredictable fire direction changes that can cut off escape routes and entrap firefighters who were positioned safely moments before.
Question 7: Which of the following actions best demonstrates proper hazard identification when a crew arrives at a new assignment?
- Begin work immediately while the crew boss scouts ahead alone
- Conduct a thorough size-up including fuel, weather, terrain, and fire behavior before committing resources (Correct answer)
- Radio back to ICP for a weather update before doing anything
- Check equipment inventory and wait for a lookout to be posted
Correct answer: Conduct a thorough size-up including fuel, weather, terrain, and fire behavior before committing resources
A complete size-up assessing fuel, weather, terrain, and current fire behavior must be completed before crews engage, ensuring hazards are identified and LCES is established.
