Red Card Fire Prevention & Protection 3 — Questions and Answers
Question 1: The 'fire triangle' consists of oxygen, heat, and:
- Wind
- Fuel (Correct answer)
- Ignition source
- Humidity
Correct answer: Fuel
The fire triangle requires fuel, oxygen, and heat — removing any one element will extinguish the fire.
Question 2: In wildland fire prevention, what does the acronym LCES stand for?
- Lookouts, Communications, Escape routes, Safety zones (Correct answer)
- Location, Containment, Escape, Suppression
- Lookouts, Crew, Equipment, Strategy
- Lines, Control, Escape, Suppression
Correct answer: Lookouts, Communications, Escape routes, Safety zones
LCES is the foundational safety system: Lookouts, Communications, Escape routes, and Safety zones.
Question 3: Which wind pattern is most associated with increased fire danger in chaparral regions of California?
- Marine layer onshore flow
- Santa Ana winds (Correct answer)
- Upslope diurnal winds
- Sea breeze
Correct answer: Santa Ana winds
Santa Ana winds are hot, dry, offshore winds that dramatically lower humidity and accelerate fire spread in California chaparral.
Question 4: A 'snag' in the context of wildland fire hazards refers to:
- A fire hose entanglement
- A standing dead tree (Correct answer)
- A fuel break in the terrain
- A trapped ember under duff
Correct answer: A standing dead tree
A snag is a standing dead tree that poses falling hazards to firefighters and can smolder and spread fire.
Question 5: Which of the following is a passive fire prevention measure for a wildland-urban interface structure?
- Deploying a structure protection sprinkler system
- Installing fire-resistant roofing and ember-resistant vents (Correct answer)
- Stationing an engine company at the property
- Creating a wet line around the building perimeter
Correct answer: Installing fire-resistant roofing and ember-resistant vents
Fire-resistant materials and ember-resistant vents are built-in structural features that reduce ignition without active firefighter intervention.
Question 6: What is the primary goal of a fuel break in wildland fire prevention?
- To provide a staging area for crew equipment
- To create a strip of reduced or modified fuels that slows fire spread (Correct answer)
- To mark the legal boundary of a national forest
- To channel fire toward a predetermined burn area
Correct answer: To create a strip of reduced or modified fuels that slows fire spread
Fuel breaks reduce fuel continuity and intensity, giving firefighters an anchor point to work from and slowing fire advance.
Question 7: At what relative humidity level are fine fuels generally considered critically dry and at high fire risk?
- Below 25% (Correct answer)
- Below 50%
- Below 75%
- Below 10% only
Correct answer: Below 25%
Relative humidity below 25% significantly increases fire danger by drying fine fuels to critical moisture levels.
