Red Card Fire Prevention & Protection 4 — Questions and Answers
Question 1: Which federal agency is responsible for issuing the Interagency Incident Management System (ICS) standards used in wildland fire?
- FEMA only
- National Wildfire Coordinating Group (NWCG) (Correct answer)
- U.S. Army Corps of Engineers
- Department of Homeland Security
Correct answer: National Wildfire Coordinating Group (NWCG)
NWCG develops and maintains standards, training, and qualifications for wildland fire management across federal agencies.
Question 2: Why is a 'black line' tactic used during prescribed burns and structural protection?
- To mark helicopter landing zones with colored paint
- To create a burned buffer zone that removes fuels adjacent to a protected area (Correct answer)
- To designate areas where suppression chemicals have been applied
- To indicate where retardant aircraft have already dropped loads
Correct answer: To create a burned buffer zone that removes fuels adjacent to a protected area
Black lining burns out fuels along roads, structures, or perimeters to create a fuel-free buffer before the main fire arrives.
Question 3: A firefighter discovers a smoldering stump 200 feet outside the fire perimeter after mop-up. The correct action is to:
- Leave it since it is small and will burn out
- Report it to the supervisor and extinguish it thoroughly (Correct answer)
- Flag it for monitoring in 24 hours
- Dig a line around it and move on
Correct answer: Report it to the supervisor and extinguish it thoroughly
Any smoldering material outside the perimeter is a spot fire risk and must be reported and fully extinguished during mop-up.
Question 4: Which of the following best describes 'ember cast' as a fire behavior phenomenon?
- The glow visible from burning trees at night
- Firebrands carried by wind that start new fires ahead of the main fire (Correct answer)
- The circular shadow cast by a smoke column
- Ash fallout after a fire passes through an area
Correct answer: Firebrands carried by wind that start new fires ahead of the main fire
Ember cast (spotting) occurs when firebrands are lofted by convection and carried by wind to ignite new fires well ahead of the fire front.
Question 5: When establishing a safety zone, the minimum recommended distance from the flame zone is based on:
- The height of the tallest flames multiplied by a safety factor (Correct answer)
- The width of the nearest road or trail
- The distance a firefighter can run in 30 seconds
- The length of the crew's longest hose lay
Correct answer: The height of the tallest flames multiplied by a safety factor
Safety zone sizing is calculated using flame length — the zone must be large enough relative to flame height to prevent radiant heat injury.
Question 6: Which mop-up technique is used to cool hot materials buried in deep duff or mineral soil?
- Progressive hose lays
- Trenching and turning with hand tools while applying water (Correct answer)
- Air tanker retardant drops
- Foam application from a distance
Correct answer: Trenching and turning with hand tools while applying water
Trenching and turning exposes buried embers to water penetration, ensuring complete extinguishment of deep-seated heat sources.
Question 7: Under the National Fire Danger Rating System (NFDRS), an 'Extreme' fire danger rating indicates:
- Prescribed burning is recommended
- Any fire starts will likely be uncontrollable and spread rapidly (Correct answer)
- Suppression resources should stand down
- Normal staffing levels are adequate
Correct answer: Any fire starts will likely be uncontrollable and spread rapidly
Extreme danger means conditions are at their worst — fires will ignite easily, burn intensely, and resist control efforts.
