CALIFORNIA FIRE BEHAVIOR ANALYST CERTIFICATION EXAM
250 Practice Questions, Correct Answers & Rationales
SUMMARIZED EXAM COVERAGE
Fire Behavior Fundamentals – Fire triangle/tetrahedron, heat transfer (conduction, convection,
radiation), combustion phases, fire intensity, rate of spread
Fire Weather – Temperature, relative humidity, wind, atmospheric stability, inversions, thermal
belts, Haines Index, Red Flag Warnings, cold front passages

hr), fuel loading, fuel continuity, live fuel moisture
Topography – Slope, aspect, elevation, canyons, ridges, saddles, chimneys, box canyons, diurnal
wind patterns
Fire Behavior Prediction – Nomograms, Rothermel model, BehavePlus, fireline intensity, flame
length, rate of spread, spotting distance, crown fire initiation
Fire Behavior Calculations – S-490, S-590, midflame windspeed, effective windspeed,
probability of ignition, KBDI, ERC, BI
Fire Safety – LCES, lookouts, communications, escape routes, safety zones, fire shelter
deployment, entrapment avoidance
Regulations & Standards – CICCS qualification guide, FIRESCOPE, NWCG standards, position
task books
SECTION 1: FIRE BEHAVIOR FUNDAMENTALS (Questions 1–40)
1. What is the primary factor influencing fire spread in wildland environments?
,Page 2 of 151
A) Ambient temperature
B) Wind
C) Relative humidity
D) Fuel moisture
Answer: B
Wind drives the direction and speed of fire spread, often overriding other environmental
conditions. It increases oxygen supply and tilts flames, preheating fuels ahead of the fire.
2. Which of the following best describes the term "spotting"?
A) Flame lengths reaching tree crowns
B) Firebrands igniting new fires ahead of the main fire
C) Fire flanking a control line
D) Fire backing into a drainage
,Page 3 of 151
Answer: B
Spotting occurs when embers are carried by wind and start new fires away from the main flame
front, creating additional ignition points that can dramatically increase fire perimeter.
3. What is the primary cause of crown fire initiation?
A) High intensity surface fire and ladder fuels
B) High air temperatures
C) Low humidity
D) Heavy duff layers
Answer: A
Crown fires often begin when surface fires reach ladder fuels, igniting the canopy. Ladder fuels
provide a continuous vertical path for fire to move from the ground into tree crowns.
4. What is the effect of low relative humidity on fire behavior?
A) Decreased ignition potential
B) Slower spread rates
, Page 4 of 151
C) Higher fuel moisture
D) Increased flammability
Answer: D
Low relative humidity reduces fuel moisture, making vegetation more flammable. Fine fuels lose
moisture rapidly when humidity is low, increasing ignition potential and rate of spread.
5. Which of the following fuels has the fastest ignition time?
A) Heavy logs
B) Duff
C) Fine fuels like grass
D) Moist shrubs
Answer: C
Fine fuels ignite quickly due to their low mass and high surface area. Grass and other fine fuels
have a high surface-to-volume ratio, allowing rapid heating and ignition.
6. Which topographic feature can significantly accelerate fire spread?
