Fire Investigator: Principles and Practice to NFPA 921 and
1033, Fourth Edition Questions With Complete Solutions
Accelerant Correct Answers Any fuel or oxidizer, often an
ignitable liquid, used to initiate a fire or increase the rate of
growth or speed the spread of fire.
Accidental Fires Correct Answers Fires for which the proven
cause does not involve an intentional human act to ignite or
spread fire into an area where the fire should not be.
Accommodation Space Correct Answers A space on a vessel
designed for people to live in.
Active Fire Protection System Correct Answers Any type of fire
protection system that automatically activates upon detection of
a fire condition.
Addressable Technology Correct Answers Fire alarm and
detection systems in which devices and system components are
assigned a data address, are capable of two-way communication,
and can perform certain activities based on signal input.
Adolescent Firesetters Correct Answers Adolescents, ages 14 to
16 years, who are often responsible for fires that occur at places
other than their homes.
Adrift Correct Answers Loose, not on moorings or towline.
Aerial Fuels Correct Answers All green or dead materials
located in the forest canopy.
,Affidavit Correct Answers A voluntary written statement of fact
or opinion made under oath and signed by the author.
Afloat Correct Answers Floating in water; not sinking.
Air Drop Correct Answers The aerial application of water,
foam, or retardant mixture directly onto the fire or threatened
area or along a strategic position ahead of the fire.
Air Entrainment Correct Answers The process of air or gases
being drawn into a fire, plume, or jet.
Air Sampling Smoke Detection Correct Answers A method of
smoke detection designed to draw air from the protected area
into a detection chamber for analysis.
Alarm Pressure Switch Correct Answers A type of initiating
device installed on all types of wet-based fire suppression
systems; the device initiates a fire alarm signal once a water
pressure threshold is met.
Alarm Signal Correct Answers A warning signal that alerts
occupants of a fire emergency.
Alloying Correct Answers The mixture of two or more metals
in which one or more of the metals is in a liquefied state.
Alternating Current (AC) Correct Answers The voltage varies
in time with a sine wave at 60 cycles per second. A sine-wave
current results if the load is resistive.
,Ambient Temperature Correct Answers Air temperature of the
surrounding environment.
Ampacity Correct Answers The current, in amperes, that a
conductor can carry continuously under the conditions of use
without exceeding its temperature rating.
Amperage Correct Answers The unit of electric current that is
equivalent to a flow of one coulomb per second; one coulomb is
defined as 6.24 x 10^18 (18th power) electrons.
Annunciation Panel Correct Answers A device that uses
indicating lamps, alphanumeric displays, or other means to
provide first responders with status, condition, and location
information concerning fire alarm system components and
devices.
Arc Correct Answers A high-temperature luminous electric
discharge across a gap where the conductor is missing or
through a medium such as charred insulation.
Arc Mapping Correct Answers The analysis of the locations
where electrical arcing has caused damage and the
documentation of the involved electrical circuits.
Arc Survey Diagrams Correct Answers Locations of electrical
arcing are identified and plotted on a diagram of the affected
area of the structure. The spatial relationship of the arc sites can
create a pattern and help establish the sequence of damage. This
analysis can be used on building circuits and electrical devices
, within a compartment to help identify or narrow the area of
origin.
Arc Tube Correct Answers A cylinder of fused silica/quartz
with electrodes at either end that is used in most mercury and
metal halide lamps.
Arc-Fault Circuit Interrupter (AFCI) Correct Answers Designed
to protect against fires caused by arcing faults in home electrical
wiring. The circuitry continuously monitors current flow.
Arced and Severed Correct Answers Occurs when wires are
arced off on the ends and possible segmented wires result.
Area of Origin Correct Answers The room, building, or general
area in which the point of origin is located.
Arson Correct Answers The crime of maliciously and
intentionally, or recklessly, starting a fire or causing an
explosion. Legal definitions of "arson" are defined by statues
and judicial decisions that vary among jurisdictions.
Aspect Correct Answers The direction the slope faces (N, E, S,
W).
Assemblies Correct Answers Manufactured parts put together to
make a completed product.
Autoignition Temperature (AIT) Correct Answers The lowest
temperature at which a combustible material ignites in air
without a spark or flame.
