NFPA 921 Exam Questions and Answers
100% Solved | Graded A+
NFPA 1033 Standard for Professional Qualifications for Fire Investigator -
✔✔Facilitates safe, accurate investigations by specifying the job
performance requirements (JPRs) necessary to perform as a fire
investigator in both the private and public sectors.
NFPA 921: Guide for Fire and Explosion Investigations - ✔✔Guide for Fire
and Explosion Investigations", is a peer reviewed document that is
published by the National Fire Protection Association (NFPA). Its purpose
is "to establish guidelines and recommendations for the safe and
systematic investigation or analysis of fire and explosion incidents" (section
1.2.1). Familiarity with NFPA 921 is strongly recommended by National
Association of Fire Investigators and the International Association of Arson
Investigators (IAAI). NFPA 921 forms a large basis of the information which
a professional fire investigator must know to pass the various Fire
Investigator Certification (NAFI and IAAI) examinations.

Spoliation - ✔✔is the destruction or alteration of evidence through intention
or ignorance.
Qualification - ✔✔The National Fire Protection Association (NFPA), through
a document known as NFPA 1033, Standard for Professional
Requirements for Fire Investigator, publishes minimum requirements for
the knowledge skills and ability of a fire investigator. Principal among these
is a 16-point list of areas in which a fire investigator is required to have
education beyond high school level. These 16 topics are:
Fire science
Fire chemistry
Thermodynamics
Thermometry
Fire dynamics
Explosion dynamics
Computer fire modeling
Fire investigation
Fire analysis
Fire investigation methodology
Fire investigation technology

Hazardous materials
Failure analysis and analytical tools
Witnesses information and/or Electronic Data - ✔✔The analysis of
observations reported by persons who witnessed the fire or were aware of
conditions present at the time of the fire as well as the analysis of electronic
data such as security camera, footage, alarm system activation, or other
such data recorded in and around the time of the fire event
Fire Patterns - ✔✔The analysis of effects and patterns left by the fire
ARC Mapping - ✔✔The analysis of the locations where electrical arcing
has caused damage and the documentation of the involved electrical
circuits
Fire Dynamics - ✔✔The analysis of the fire dynamics[i.e., the physics and
chemistry of fire initiation and growth and the interaction between the fire
and the buildings system
Code - ✔✔A standard that is an extensive compilation of provisions
covering broad subject matter or that is suitable for adoption into law
independently of other codes and standards.
Standard - ✔✔An NFPA standard, the main text of which contains only
mandatory provisions using the word "shall" to indicate requirements and
, ©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.
that is in a form generally suitable for mandatory reference by another
standard or code or for adoption into law. Includes all NFPA standards,
including codes, standards, recommended practices and guides.
Absolute Temperature - ✔✔A temperature measured in Kelvins or
Rankines
Accelerant - ✔✔A fuel or oxidizer, often an ignitable liquid, intentionally
used to initiate a fire or increase the rate of growth or spread of fire.
Accident - ✔✔An unplanned event that interrupts an activity and sometimes
causes injury or damage or a chance occurrence arising from unknown
causes; an unexpected happening due to carelessness, ignorance, and the
like.
Active Fire Protection System - ✔✔A system that uses moving mechanical
or electrical parts to achieve a fire protection goal
Ambient - ✔✔Someone's or something's surroundings, especially as they
pertain to the local environment; for example, ambient air and ambient
temperature.
Ampacity - ✔✔The maximum current, in amperes, that a conductor can
carry continuously under the conditions of use without
Exceeding its temperature rating.
