PRACTICE QUESTION BANK – 200 MCQs
Question 1
What is the PRIMARY goal of a fire investigation?
A) To estimate fire damage costs
B) To identify the origin and cause of the fire
C) To find someone to blame
D) To complete paperwork for insurance
Correct Answer: B) To identify the origin and cause of the fire
Rationale: The fundamental purpose of any fire investigation is to determine
where the fire started (origin) and what ignited it (cause). All other objectives
are secondary.
Question 2
Which NFPA standard is the primary guide for fire and explosion
investigations?
A) NFPA 70
B) NFPA 921
C) NFPA 101
D) NFPA 1500
Correct Answer: B) NFPA 921
Rationale: NFPA 921 – Guide for Fire and Explosion Investigations – is the
authoritative standard that establishes the scientific methodology for fire
investigation.
,Question 3
Which NFPA standard outlines the professional qualifications for fire
investigators?
A) NFPA 921
B) NFPA 1033
C) NFPA 70
D) NFPA 13
Correct Answer: B) NFPA 1033
Rationale: NFPA 1033 – Standard for Professional Qualifications for Fire

What is the most reliable laboratory method for identifying ignitable liquids
in fire debris?
A) Visual inspection
B) Odor detection
C) Gas Chromatography-Mass Spectrometry (GC-MS)
D) Ultraviolet light examination
Correct Answer: C) Gas Chromatography-Mass Spectrometry (GC-MS)
