CERTIFIED FIRE INVESTIGATOR PRACTICE
SCRIPT 2026 FULL ANSWERS GRADED A+
⩥ Define Backdraft.
Answer: A deflagration resulting from the sudden introduction of air into
a confined space containing oxygen-deficient products of incomplete
combustion
⩥ Define a "Bead".
Answer: A rounded globule of re-solidified metal at the end of the
remains of an electrical conductor caused by arcing and characterized by
a sharp line of demarcation between the melted and un-melted conductor
surfaces.
⩥ What is a "B.L.E.V.E.?".
Answer: Boiling Liquid Expanding Vapor Explosion
⩥ Define the "Blast Pressure Front".
Answer: The expanding leading edge of an explosion reaction that
separates a major difference in pressure between normal ambient
pressure ahead of the front and potentially damaging high pressure at
and behind the front
⩥ What is the Calcination of Gypsum?.
,Answer: A fire effect realized in gypsum products, including wallboard,
as a result of exposure to heat that drives off free and chemically bound
water
⩥ Define "Cause".
Answer: The circumstances, conditions or agencies that brought about or
resulted in the fire or explosion incident, damage to property resulting
from the fire or explosion incident, or bodily injury or loss of life
resulting from the fire or explosion incident
⩥ Define a "Ground Fault".
Answer: An unintended current that flows outside the normal circuit
path, such as (a) through the equipment grounding conductor; (b)
through conductive material in contact with lower potential (such as
earth), other than the electrical system ground (metal, water, or
plumbing pipes, etc., or (c) through a combination of these ground return
paths
⩥ Define "Heat".
Answer: A form of energy characterized by vibration of molecules and
capable of initiating and supporting chemical changes of state
⩥ Define "Heat Flux".
Answer: The measure of the rate of heat transfer to a surface or an area
, ⩥ Define "Heat Transfer".
Answer: The exchange of thermal energy between materials through
conduction, convection, and/or radiation
⩥ Define an "Ignitable Liquid".
Answer: Any liquid or liquid phase of any material that is capable of
fueling a fire, including a flammable liquid, combustible liquid, or any
other material that can be liquefied or burned
⩥ Define "Ignition".
Answer: The process of initiating self-sustained combustion
⩥ Define "Ignition Temperature".
Answer: The maximum temperature a substance should attain in order to
ignite under specific test conditions
⩥ What is an "Incendiary Fire?".
Answer: A fire intentionally ignited in an area or under circumstances
where and when there should not be a fire
⩥ What is "Inductive Reasoning?".
Answer: The process by which a person starts from a particular
experiences and proceeds to generalizations. The process by which
