Chapter 2 - Fire Behavior Flashcards
The process of formally accepting a code and setting it into action.
Adoption
The instances in which legislation states that a certain code and specific edition will be enforced within the jurisdiction.
Adoption by Reference
The model code is republished as an ordinance and a license must be purchased to do so.
Adoption by transcription
A civil rights law passed by Congress in 1990 prohibiting, under certain circumstances, discrimination based on disability.
Americans with Disabilities Act.
An organization, office, or individual responsible for enforcing the requirments of a code, or standards, or for approving equipment, materials, an installation, or a procedure.
Authority having Jurisdiction (AHJ)
A sudden and explosive ignition of pressurized, superheated, and oxygen-deprived gases within an enclosed space when oxygen is reintroduced.
Backdraft
When a liquid in a vessel is heated to the point it boiled, expands, and can no longer be contained by the vessel.
Boiling liquid expanding vapor explosion (BLEVE)
A fire involving ordinary combustibles such as paper, cloth, wood, plastics, and rubber.
Class A fire
A fire involving flammable and combustible liquids, gases, and greases.
Class B fire
A fire involving energized electrical equipment.
Class C fire
A fire involving combustible metals and alloys such as magnesium, sodium, lithium, and potassium.
Class D fires
A fire involving high temperature combustible cooking fuels such as vegetable or animal oils and fats.
Class K fire
A systematically arranged law, rule, or regulation that tells people what they can and cannot do and when and where they can do those things.
Code
Codes arranged according to a system
Codified
A liquid with a flash point at or above 100F
Combustible Liquid
Conditions prevalent in most occupancies that increase the chances of a fire starting.
Common Fire Hazard
The transfer of heat through a solid object
Conduction
A large and destructive fire that jumps natural barriers
Conflagration
The transfer of heat through air and liquid currents
Convection
The point at which the supply of oxygen to a fire os depleted and the fire finally extinguishes itself.
Decay Stage
A plan for residents who are completely unable to navigate and evacuate a building on their own, to remain in the structure in a protected area until the fire department can assist them evacuating.
Defend in place strategy
An automatic sprinkler system designed to protect areas that could have a fast spreading fire that could engulf an entire area.
Deluge sprinkler system
An automatic sprinkler system that operated with air or nitrogen under constant pressure in the pipes instead of water, which would freeze in cold weather.
Dry Pipe sprinkler system
A sprinkler system designed to protect pallet and rack storage up to 35 feet through the application of increased flow densities.
Early suppression fast response sprinkler.
A communications system that is part of the fire alarm system that allows manual or automatic live or prerecorded voice information alarm signals, or other signals to be sent to the entire building or to select areas.
Emergency Voice Alarm Communications System
A rated assembly that provides a protected panther to the exit discharge.
Exit
The point from anywhere in the building to an exit.
Exit Access
The portion of the means of egress between the exterior exit door and the public way.
Exit discharge
When the heat given off by a fire is transferred to other materials and begins heating them. A chemical reaction that released energy by light or heat.
Ex other ic reaction
Burning or combustion, which is a chemical chain reaction that includes a self sustaining rapid oxidation of a fuel accompanied by the release of heat and light.
Fire
Receives the signal from the detection device and then directs the signal to the signaling devices.
Fire alarm control panel
A condition that encourages a fire to start or increase the extent or severity of fire.
Fire Hazard
Today’s concept of the fire triangle, it includes a fourth element, the molecular chain reaction, which allows for a self-sustaining chemical reaction and flame propagation.
Fire Tetrahedron
A fire science model used to explain the chemical reaction of fire.
Fire Triangle
A liquid having a flash point of below 100F
Flammable Liquid
The minimum temperature at which a liquid gives off suffice but vapor to form an ignitable mixture at the surface but not sufficient to sustain combustion.
Flash Point
The transition between the growth phase and the fully developed stage. It is the point when all contents of a from reach their ignition temperature and quickly change to a fully developed fire.
Flashover
The material being burned in the combustion process. it is a form or matters than cab be found as a solid, liquid, or gas.
Fuel
The point at which the fire is consuming the maximum amount of fuel.
Fully developed stage
