Failure Analysis - ANSWER A logical, systematic examination of n item, component,
assembly, or structure and its place and function within a system, conducted in order to
identify and analyze the probability, causes, and consequences of potential and real
failures.
Fire Analysis - ANSWER The process of determining the origin, cause, development,
responsibility, and, when required, a failure analysis of a fire or explosion.
Fire Cause - ANSWER The circumstances, conditions, or agencies that bring together
a fuel, ignition source, and oxidizer resulting in a fire or combustion explosion.
Fire Dynamics - ANSWER The detailed study of how chemistry fire science, and the
engineering disciplines of fluid mechanics and heat transfer interact to influence fire
behavior.
Fire Patterns - ANSWER The visible or measurable physical changes, or identifiable
shapes, formed by a fire effect or group of fire effects.
Fire Science - ANSWER The body of knowledge concerning the study of fire and
related subjects and their interaction with people, structures, and the environment.
First Fuel Ignited - ANSWER The first fuel ignited is that which first sustains
combustion beyond the ignition source.
Flame Front - ANSWER The flaming leading edge of a propagating combustion
reaction zone.
Flameover - ANSWER The condition where unburned fuel from the originating fire has
accumulated in the ceiling layer to a sufficient concentration that it ignites and burns;
can occur without ignition of, or prior to, the ignition of other fuels separate from the
origin.
Flammable Limit - ANSWER The upper or loser concentration limit at a specified
temperature and pressure of a flammable gas or a vapor of an ignitable liquid and air,
expressed as a percentage of fuel by volume that can be ignited.
Flammable Liquid - ANSWER A liquid that has a closed cup flash point that is below
100 degrees F.
, Flammable Range - ANSWER The range of concentrations between the lower and
upper flammable limits.
Flash Fire - ANSWER A fire that spreads by means of a flame front rapidly through a
diffuse fuel, such as dust, gas, or the vapors of an ignitable liquid, without the
production of damaging pressure.
Flash Point of a Liquid - ANSWER The lowest temperature of a liquid at which the
liquid gives of vapors at a sufficient rate to support a momentary flame across its
surface.
Flashover - ANSWER A transition phase in the development of a compartment fire n
which surfaces exposed to thermal radiation reach ignition temperature more or less
simultaneously and fire spreads rapidly throughout the space, resulting in full room
involvement or total involvement of the compartment or enclosed space.
Fuel - ANSWER A material that will maintain combustion under specified environmental
conditions.
Fuel Gas - ANSWER Natural gas, manufactured gas, LP-Gas, and similar gases
commonly used for commercial or residential purposes.
Fuel Load - ANSWER The total quantity of combustible contents of a building, space,
or fire area, including interior finish and trim, expressed in heat units or the equivalent
weight in wood.
Fuel-Controlled Fire - ANSWER A fire in which the heat release rate and growth rate
are controlled by the characteristics of the fuel, such as quantity and geometry, and in
which adequate air for combustion is available.
Ground - ANSWER A conducting connection between an electrical circuit or equipment
and earth or to some conducting body that serves in place of the earth.
Ground Fault - ANSWER An unintended current that flows outside the normal circuit
path.
Heat - ANSWER A form of energy characterized by vibration of molecules and capable
of initiating and supporting chemical changes and changes of state.
Heat and Flame Vector - ANSWER An arrow used in a fire scene drawing to show the
direction of heat, smoke, or flame flow.
