heat transfer interact to influence fire behavior.
/.Fire Patterns - Answer-Visible or measurable physical changes or shapes formed by
fire effects.
/.Fire Spread - Answer-The movement of fire from one place to another.
/.Flame - Answer-A body or stream of gaseous material involved in the combustion
process and emitting radiant energy.
/.Flame Front - Answer-The leading edge of a propagating combustion reaction zone.

heat loss within a material.
/.Explosible - Answer-A material with a pressure ratio at ignition equal to or greater than
2.0 in any explosibility test.
/.Detonation - Answer-The propagation of a combustion zone at a velocity greater than
the speed of sound.
/.Clean Burn - Answer-A distinct fire effect on noncombustible surfaces after burning off
combustible layers.
/.BLEVE - Answer-Boiling liquid expanding vapor explosion.
/.Explosion Dynamics - Answer-The study of how chemistry, physics, fluid mechanics,
and heat transfer interact to influence explosion behavior.
/.Explosive Material - Answer-Any material that can act as a fuel for an explosion.
/.Exposed Surface - Answer-The side of a structure or object directly exposed to fire.
/.Failure - Answer-Distortion, breakage, deterioration, or other fault that results in
unsatisfactory performance.
/.Failure Analysis - Answer-A logical examination of an item to identify and analyze
potential and real failures.
/.Finish Rating - Answer-The time in minutes for a stud or joist to reach a specific
temperature rise in a protected combustible assembly.
/.Fire Analysis - Answer-The process of determining the origin, cause, development,
and responsibility of a fire or explosion.
/.Fire Area - Answer-The boundary of fire effects within a scene where the area of origin
is located.
/.Fire Cause - Answer-The circumstances, conditions, or agencies that result in a fire or
combustible explosion.
/.Fire Hazard - Answer-Any situation, process, material, or condition that can cause a
fire or explosion and poses a threat to life or property.
/.Flash Fire - Answer-A fire that spreads rapidly through a diffuse fuel without the
production of damaging pressure.
