AC - CORRECT ANSWER: The voltage varies in time with a sine wave at 60 cycles per
second. A sine-wave current results if the load is resistive.
Accelerant - CORRECT ANSWER: Any fuel or oxidizer, often an ignitable liquid, used to
initiate a fire or increase the rate of growth or speed the spread of the fire.
Accidental Fires - CORRECT ANSWER: 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.
Accidental Fires - CORRECT ANSWER: 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 ANSWER: A space on a vessel designed for
people to live in.
Active Fire Protection System - CORRECT ANSWER: Any type of fire protection system
that automatically activates upon detection of a fire condition.
Addressable Technology - CORRECT ANSWER: 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 ANSWER: Adolescents, ages 14 to 16 years, who
are often responsible for fires that occur at places other than their homes.
Adrift - CORRECT ANSWER: Loose, not on moorings or towline.
Aerial Fuels - CORRECT ANSWER: All green or dead materials located in the forest
canopy.
Affadavit - CORRECT ANSWER: A voluntary written statement of fact or opinion made
under oath and signed by the author.
Afloat - CORRECT ANSWER: Floating in water; not sinking
Air Drop - CORRECT ANSWER: 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 ANSWER: The process of air or gases being drawn into a
fire, plume, or jet.
Air Sampling Smoke Detection - CORRECT ANSWER: A method of smoke detection
designed to draw air from the protected area into a detection chamber for analysis.
Alarm Pressure Switch - CORRECT ANSWER: 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 ANSWER: A warning signal that alerts occupants of a fire
emergency.
Alloying - CORRECT ANSWER: The mixing of two or more metals in which one or more
of the metals is in a liquid state.
,Ambient Temperature - CORRECT ANSWER: Air temperature of the surrounding
enviroment.
Ampacity - CORRECT ANSWER: The maximum current, in amperes, that a conductor
can carry continuously under the conditions of use without exceeding its temperature
rating.
Amperage - CORRECT ANSWER: The unit of electric current that is equivalent to a flow
of one coulomb per second; one coulomb is defined as 6.24 x 1018 electrons.
Annunciation Panel - CORRECT ANSWER: 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 ANSWER: High-temperature luminous electric discharge across a gap
or through a medium such as charred insulation.
Arc Mapping - CORRECT ANSWER: The analysis of the locations where electrical
arcing has caused damage and the documentation of the involved electrical circuits.
Arc Survey Diagrams - CORRECT ANSWER: 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 ANSWER: 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 ANSWER: Designed to protect against
fires caused by arcing faults in home electrical wiring. The circuitry continuously
monitors current flow.
, Arced and Severed - CORRECT ANSWER: Occurs when wires are arced off on the
ends and possible segmented wires result.
Area of Origin - CORRECT ANSWER: The room, building, or general area in which the
point of origin is located.
Arson - CORRECT ANSWER: The crime of maliciously and intentionally, or recklessly,
starting a fire or causing an explosion. Legal definitions are defined by statutes and
judicial decisions that vary among jurisdictions.
Aspect - CORRECT ANSWER: The direction the slope faces (N,E,S,W)
Assemblies - CORRECT ANSWER: Manufactured parts put together to make a
completed product.
Autoignition Temperature - CORRECT ANSWER: The lowest temperature at which a
combustible material ignites in air without a spark or flame.
Backflow Valve - CORRECT ANSWER: Prevents gas from re-entering a container or
combustion system.
Balance Pressure Proportioner - CORRECT ANSWER: A proportioner that uses an
atmospheric tank and pump to introduce the foam concentrate into the system with the
water supply.
Balloon Frame Construction - CORRECT ANSWER: A construction type in which the
exterior wall studs go from the foundation wall to the roofline. The floor joists are
attached to the walls by the use of a ribbon board, which creates an open stud channel
between floors, including the basement and attic.
