1. In fire dynamics, the primary factor that drives the development and
spread of fire within a compartment is:
A. Conduction
B. Radiation
C. Convection
D. Evaporation
Convection currents transfer heat and smoke, influencing fire growth
and spread more significantly than conduction or radiation in a
compartment fire.
2. The scientific method step where the investigator formulates a
testable prediction based on theory is called:
A. Observation
B. Hypothesis formulation
C. Data collection
D. Peer review
Hypothesis formulation is the step in the scientific method where a
testable and falsifiable prediction is developed from theory.
3. A “flashover” condition in a compartment fire is best described as:
A. Ignition of exterior fuel sources
B. Rapid transition to full room involvement
C. Backdraft without ventilation
D. Slow smoldering combustion
, Flashover is the near-simultaneous ignition of all combustible
surfaces in a compartment due to thermal feedback.
4. In arson investigation, the concept of “point of origin” refers to:
A. Last area to burn
B. Area of greatest smoke damage
C. First area where fire ignited
D. Area with least structural damage
The point of origin is defined as the first area ignited and is crucial to
establishing how the fire started.
5. An accelerant detection canine team is best used to:
A. Measure temperature gradients
B. Document structural collapse
C. Locate potential ignitable liquid residues
D. Analyze electrical wiring
Canine teams trained in accelerant detection assist in locating
potential traces of ignitable liquids for sampling.
6. A properly collected ignitable liquid sample should be stored in:
A. A glass jar with metal lid
B. A plastic bag
C. A clean, unused metal can
D. A paper envelope
Unused metal cans with airtight seals prevent vapors from escaping
and minimize contamination.
7. The classification of fire cause that includes natural, accidental,
incendiary, and undetermined is established by:
A. NFPA 1001
B. IAAI standards
C. NFPA 921
D. OSHA regulations
NFPA 921 Fire Investigation provides the widely accepted
classification categories for fire cause.
8. When documenting the fire scene, the most comprehensive method
of capturing spatial relationships is:
A. Handwritten notes
B. Sketches alone
, C. Photographs with scale
D. Verbal reports only
Photographs with scale provide a detailed, measurable visual record
of the scene.
9. In scene preservation, the investigator’s priority is to:
A. Remove debris for clarity
B. Interview witnesses first
C. Prevent disturbance of evidence
D. Conduct laboratory tests onsite
Preserving evidence integrity by preventing disturbance is essential
before detailed examination.
10. A “backdraft” is a phenomenon caused by:
A. Over-ventilation
B. Sudden introduction of oxygen into a fuel-rich environment
C. Spontaneous combustion
D. Flashover progression
A backdraft occurs when oxygen rapidly enters a smoldering, fuel-
rich compartment, causing explosive ignition.
11. The presence of low burn patterns that appear to move uphill on
a vertical surface may indicate:
A. Gravity-fed fire
B. Use of an accelerant
C. Wind-aided burn
D. Electrical arcing
Accelerants can cause irregular burn patterns that defy normal heat-
driven fire behavior.
12. The fire investigator’s reference for evaluating electrical causes
is primarily:
A. NFPA 70E
B. NFPA 921
C. IBC
D. ASTM E119
NFPA 921 provides guidance on evaluating electrical systems as
potential fire causes.
