NAFI CFEI Practice Exam Questions and Answers |
Latest Update | Exam Prep
1. The "point of origin" is best described as which of the following?
The obvious design and path of burned material from where the fire
initially started
The happenings that occur in order for the heat source and material to
come together and ignite the fire
The vicinity in which the ignition source and material came together for
the first time
The exact physical location where the heat source and the fuel came
into contact to begin the fire
2. What is one of the primary uses of a multimeter in fire investigations?
To assess the structural integrity of a building.
To measure electrical properties such as voltage and resistance.
To document witness statements.
To analyze chemical residues from the fire scene.
3. What type of meter is typically used to measure resistance in a fire alarm
circuit?
dB Meter
Manometer
Multimeter
Tone generator
,4. In a fire investigation, if a building had limited ventilation due to closed
windows and doors, what implications might this have on the fire patterns
observed?
The fire patterns will be uniform and predictable regardless of
ventilation.
The fire patterns will be indistinguishable from those in well-ventilated
areas.
The fire patterns may show more concentrated burn areas and less
overall spread due to limited airflow.
The fire patterns will indicate a faster spread due to increased heat
retention.
5. A V pattern is best described as:
an observation cut in the roof of a building.
a design that smoke and fire makes on the interior and exterior
walls of a fire building.
a cut used in forcible entry to open a rolling door.
the shape a stream takes when leaving a straight tip nozzle.
6. The first step in the scientific method is
analyzing data
forming a hypothesis
making observation
doing experiment
proposing a theory
, 7. What is the initial step in the scientific method used in fire investigation?
Hypothesis
Experimentation
Observation
Conclusion
8. What term describes the influence of personal beliefs or opinions on the
interpretation of evidence in fire investigations?
Evidence
Fire tetrahedron
Bias
Chain of custody
9. Describe how bias can impact the outcomes of a fire investigation.
Bias helps investigators focus on the most likely cause of the fire.
Bias has no effect on the investigation outcomes.
Bias can improve the efficiency of the investigation.
Bias can lead to misinterpretation of evidence and incorrect
conclusions.
10. Describe how ventilation can impact the appearance of fire patterns in an
investigation.
Ventilation affects fire patterns by altering the flow of air, which
can change the intensity and spread of the fire.
Ventilation has no effect on fire patterns as it only influences smoke
movement.
