Red Card Fire Prevention & Protection 2 — Questions and Answers
Question 1: Which condition creates the highest risk of spotting during a wildland fire?
- High humidity and calm winds
- Low humidity, fine fuels, and strong erratic winds (Correct answer)
- Moist heavy fuels and steady winds
- Cool temperatures and overcast skies
Correct answer: Low humidity, fine fuels, and strong erratic winds
Low humidity dries fine fuels, strong erratic winds carry embers long distances, dramatically increasing spot fire risk.
Question 2: A 'defensible space' around a structure primarily serves to:
- Improve visibility for firefighters approaching the structure
- Reduce fuel continuity so fire cannot easily reach the building (Correct answer)
- Provide a landing zone for air tankers
- Mark the perimeter of a safety zone
Correct answer: Reduce fuel continuity so fire cannot easily reach the building
Defensible space reduces or removes fuels around structures so fire intensity is lowered before reaching the building.
Question 3: During a prescribed burn, what is the primary purpose of holding forces?
- Igniting the fire along pre-planned lines
- Preventing the fire from escaping the designated burn area (Correct answer)
- Mapping the fire perimeter with GPS
- Monitoring smoke column height
Correct answer: Preventing the fire from escaping the designated burn area
Holding forces patrol the fire perimeter and suppress any escapes to keep the prescribed fire within the planned area.
Question 4: Which class of fire extinguisher is rated for use on ordinary combustibles like wood and grass?
- Class B
- Class C
- Class A (Correct answer)
- Class D
Correct answer: Class A
Class A extinguishers are designed for ordinary solid combustibles such as wood, paper, and dry vegetation.
Question 5: A fire that burns through the crowns of trees continuously is called a:
- Surface fire
- Ground fire
- Crown fire (Correct answer)
- Torching fire
Correct answer: Crown fire
A crown fire spreads through the upper canopy layer continuously and is independent of surface fire spread.
Question 6: What fuels condition is described as having a 1-hour timelag?
- Dead woody material 0 to 0.25 inch in diameter (Correct answer)
- Dead woody material 3 to 8 inches in diameter
- Live herbaceous vegetation
- Compacted duff layers
Correct answer: Dead woody material 0 to 0.25 inch in diameter
1-hour timelag fuels are fine dead materials up to 0.25 inch diameter that respond rapidly to atmospheric moisture changes.
Question 7: Which action should a firefighter take FIRST upon discovering an unexpected fire start near the crew's work area?
- Immediately begin suppression attack without notifying anyone
- Notify the supervisor and request additional resources before engaging (Correct answer)
- Retreat to the nearest hilltop to assess the situation
- Set a backfire to stop the spread
Correct answer: Notify the supervisor and request additional resources before engaging
Notification ensures additional resources and support are requested while the supervisor coordinates the response.
