Red Card Hazard Identification & Assessment 2 — Questions and Answers
Question 1: Which condition is most indicative of an impending blowup on a wildland fire?
- Relative humidity rising above 30%
- Rapid increase in fire intensity with column collapse (Correct answer)
- Fire moving downhill into a valley
- Smoke color changing from white to gray
Correct answer: Rapid increase in fire intensity with column collapse
A collapsing smoke column causes air to rush inward and downward, dramatically increasing fire intensity and rate of spread in a blowup.
Question 2: What does a 'chimney' terrain feature represent on a wildland fire?
- A safe anchor point near a road
- A drainage or gully that channels fire rapidly uphill (Correct answer)
- A wide saddle suitable for staging equipment
- A rocky area with minimal fuel load
Correct answer: A drainage or gully that channels fire rapidly uphill
Chimneys are steep drainages or gullies that act as natural pathways for fire to travel rapidly uphill, creating extreme danger for firefighters above.
Question 3: When assessing fuel moisture, which reading indicates critically dry fine fuels most prone to rapid fire spread?
- 25% moisture content
- 15% moisture content
- 5% moisture content (Correct answer)
- 35% moisture content
Correct answer: 5% moisture content
Fine fuel moisture below 8% is considered critically dry; 5% indicates extremely dangerous conditions with potential for explosive fire behavior.
Question 4: What hazard does a 'saddle' in ridge terrain present during a wildland fire?
- It blocks wind and reduces fire spread
- It creates a low point where cold air pools, suppressing fire
- It acts as a wind funnel, accelerating fire through the gap (Correct answer)
- It provides natural firebreaks due to rocky outcrops
Correct answer: It acts as a wind funnel, accelerating fire through the gap
Saddles channel and accelerate wind through the low point in a ridge, dramatically increasing fire spread rate and intensity on the downwind side.
Question 5: Which of the following is a LCES component that firefighters must establish before engaging a wildland fire?
- Lookouts, Communications, Escape routes, Safety zones (Correct answer)
- Logistics, Command, Equipment, Suppression
- Location, Crew size, Engine support, Staging
- Leadership, Coordination, Enforcement, Strategy
Correct answer: Lookouts, Communications, Escape routes, Safety zones
LCES stands for Lookouts, Communications, Escape routes, and Safety zones — the four essential elements that must be in place before firefighting begins.
Question 6: A firefighter notices the fire's smoke column is leaning sharply toward their position. What does this indicate?
- The fire is losing intensity and dying down
- Wind is pushing the fire toward the firefighter's location (Correct answer)
- The fire has established a strong convective column
- Humidity is increasing and conditions are improving
Correct answer: Wind is pushing the fire toward the firefighter's location
A smoke column leaning toward you means the wind — and fire — are moving in your direction, requiring immediate reassessment of escape routes and safety zones.
Question 7: Which environmental cue signals that a spot fire has started ahead of the main fire perimeter?
- A decrease in wind speed near the fire line
- Smoldering debris or flames appearing in unburned fuel beyond the fire edge (Correct answer)
- The main fire front slowing its rate of spread
- Increased retardant coverage on adjacent fuels
Correct answer: Smoldering debris or flames appearing in unburned fuel beyond the fire edge
Spot fires occur when embers are carried ahead of the main fire and ignite in unburned fuels, creating new ignition points that can cut off escape routes.
