1. TCFP Arson Investigator Certification Examination
2. Which of the following is the PRIMARY objective of an arson
investigator at a fire scene?
A. To immediately determine insurance liability
B. To establish fire suppression tactics for future incidents
C. To determine origin and cause of the fire through systematic
investigation
D. To conduct criminal prosecution in court on behalf of the state
Correct Answer: C. The primary objective of an arson investigator is
to determine the origin and cause of a fire using systematic and
scientific investigative methods while preserving evidence.
3. When securing a fire scene for investigation, which action should be
taken FIRST?
A. Begin interviewing witnesses
B. Establish scene perimeter and restrict access
C. Collect physical evidence from the origin area
, D. Conduct a full structural overhaul of debris
Correct Answer: B. Securing the perimeter is the first priority to
prevent contamination or loss of evidence before any investigative
steps begin.
4. Which indicator is MOST consistent with intentional fire setting?
A. Uniform burn patterns throughout the structure
B. Multiple points of origin without natural explanation
C. Fire confined to a single room of origin
D. Presence of accidental electrical failure
Correct Answer: B. Multiple points of origin often suggest intentional
ignition rather than accidental fire development.
5. The term “point of origin” refers to:
A. The location where firefighters first applied water
B. The area where the fire started and gained ignition
C. The structural weakest point of collapse
D. The location where smoke is most visible
Correct Answer: B. The point of origin is the specific area where the
fire initially started and began to spread.
6. Which document is MOST critical in maintaining chain of custody for
fire scene evidence?
A. Incident action plan
B. Evidence log or evidence tracking form
C. Dispatch report
D. Building occupancy permit
Correct Answer: B. An evidence log ensures accountability and
continuity of physical evidence from collection to court presentation.
7. The NFPA standard most commonly associated with fire investigation
procedures is:
A. NFPA 10
, B. NFPA 70
C. NFPA 921
D. NFPA 1500
Correct Answer: C. NFPA 921 is the recognized guide for fire and
explosion investigations and outlines systematic methodology.
8. Which pattern is MOST indicative of a liquid accelerant use?
A. Inverted cone burn pattern
B. Circular burn pattern around ceiling
C. Uniform charring at all heights
D. No observable pattern changes
Correct Answer: A. An inverted cone pattern may indicate the use of
accelerants due to downward and outward fire spread.
9. What is the primary purpose of interviewing witnesses at a fire scene?
A. To assign blame immediately
B. To collect subjective and observational information about fire
development
C. To determine insurance fraud
D. To establish structural engineering faults
Correct Answer: B. Witness interviews provide contextual
observations that help reconstruct fire development.
10. Which type of evidence is considered MOST fragile at a fire
scene?
A. Structural beams
B. Burned appliances
C. Volatile ignitable liquids
D. Brick foundations
Correct Answer: C. Volatile ignitable liquid evidence can evaporate or
be destroyed easily if not properly collected.
