1. Which of the following best describes the primary purpose of the TCFP
Fire Investigator Certification Examination?
A. To assess proficiency in emergency medical response procedures during
structure fires
B. To evaluate competency in fire scene examination, origin and cause
determination, and evidence preservation
C. To certify candidates in fire suppression tactics and hose deployment
techniques
D. To test administrative skills in fire department budgeting and personnel
management
The Fire Investigator certification is designed to ensure candidates can
properly conduct fire scene investigations, including determining origin and
cause, analyzing fire patterns, and preserving evidence in accordance with
professional fire investigation standards such as NFPA 1033.
2. Which NFPA standard most directly governs professional qualifications
for fire investigators?
,A. NFPA 1001
B. NFPA 1033
C. NFPA 1500
D. NFPA 1710
NFPA 1033 establishes the minimum job performance requirements for fire
investigators, including knowledge and skills related to fire scene analysis
and determination of origin and cause.
3. A fire investigator arrives at a scene. Which of the following is the
FIRST priority action?
A. Begin collecting physical evidence immediately
B. Conduct a safety assessment of the scene
C. Interview witnesses before entering the structure
D. Begin photographing interior fire damage patterns
Safety is the first priority at any fire scene because investigators must
identify structural, chemical, electrical, and environmental hazards before
beginning any evidence collection or interior operations.
4. What is the primary purpose of conducting an exterior survey of a fire
scene?
A. To determine insurance liability
B. To preserve evidence and identify hazards before entry
C. To immediately locate witnesses nearby
D. To determine firefighter performance during suppression
An exterior survey helps investigators identify hazards, preserve evidence,
and understand fire progression while maintaining scene integrity before
interior examination.
5. Which of the following BEST defines “origin” in fire investigation
terminology?
,A. The location where the most structural damage occurred
B. The area where the fire was first discovered by occupants
C. The point where ignition began and combustion was initiated
D. The room with the highest temperature readings
The origin is the specific area where ignition first occurred, which is critical
in determining how and why the fire started.
6. What is the primary function of fire pattern analysis at a fire scene?
A. To determine insurance fraud potential
B. To identify the method of suppression used
C. To interpret burn patterns to help locate origin and fire progression
D. To estimate property replacement value
Fire pattern analysis helps investigators interpret burn and damage
indicators to determine the fire’s origin and movement throughout the
structure.
7. Which hazard is MOST commonly associated with structural collapse at
a fire scene?
A. Biological hazard
B. Structural hazard
C. Mechanical hazard
D. Radiological hazard
Structural hazards involve compromised building integrity, which can lead
to collapse and pose significant danger to investigators.
8. Which of the following is considered a chemical hazard at a fire scene?
A. Exposed electrical wiring
B. Asbestos or toxic combustion products
C. Unstable building framing
D. Broken glass debris
, Chemical hazards include toxic gases, residues, and hazardous materials
produced or released during combustion.
9. What is the primary purpose of evidence preservation in fire
investigation?
A. To increase prosecution success rates only
B. To ensure physical evidence remains uncontaminated and legally
admissible
C. To speed up insurance claim processing
D. To remove debris from the scene quickly
Evidence preservation ensures that physical materials are protected from
contamination or alteration so they can be reliably analyzed and used in
legal proceedings.
10. Which of the following BEST describes “requisite knowledge” in
NFPA 1033?
A. Hands-on firefighting experience only
B. Required theoretical understanding necessary to perform job tasks safely
and effectively
C. Administrative knowledge of fire department budgeting
D. Knowledge limited to emergency medical procedures
Requisite knowledge refers to the essential theoretical understanding of
fire science, behavior, investigation techniques, and safety principles
needed for competent performance.
11. What is the purpose of identifying the “area of origin” in a fire
investigation?
A. To determine the insurance payout amount
B. To locate where the fire started and focus investigative efforts
