fire triangle - ANSWERheat, oxygen, and fuel are sides of the___________

removal of any 1 component - ANSWERwill cause the fire to be extinguished

the fire tetrahedron - ANSWER____________________, or all components are
necessary for a fire to occur

tetrahedron - ANSWERthe fire triangle

- sun, open flame, chemical reaction, sparks, friction, static electricity, biological
processes

21% oxygen - ANSWERearths atmosphere

vapors - ANSWERonly ________ burn

liquids and solids - ANSWERare too dense/must be vaporized 1st

burn - ANSWERthe tendency of a substance to vaporize is an indication of its ability
to ______

solids - ANSWER-liquids vaporize more readily than __________

gases - ANSWER_________ are already in a vapor state

oxygen-heat-fuel - ANSWERyou can have ________-________-___________ in the
same place and still not have a fire

fuel-oxygen - ANSWER_______-________ relationship must be balanced, i.e., must
be in the flammable range

ignition temperature - ANSWERheat must be sufficient to bring fuel to its

-remove fuel, or

Class A - ANSWERcombustile solids (trashcan, paper,wood)

Class B - ANSWERcombustile; flammable liquids

Class C - ANSWERenergized electrical equipment (wiring)

Class D - ANSWERcombustile metals (Aluminum, Magnesium)

Class K - ANSWERcooking material (cooking oils)

flash point of a liquid - ANSWER-the lowest temp. at which a liquid gives off
sufficient vapor to form an ignitable mixture at the surface of the liquid
-fire flashes across the surface given sufficient oxygen and external source of
ignition
-lowest temp. at which we can have a fire
-indicator of the severity of a fire hazard

fire point - ANSWERjust above the flash point- liquid vaporizes rapidly enough to
sustain continuous combustion

ignition temperature - ANSWERlowest temp. of a combustible substance at which
sustained combustion will occur without spark or flame

spontaneous combustion - ANSWERheat is generated by a chemical action within a
substance and this continues until you have ignition
-begins with oxidation and combines with oxygen and gives off energy in the form of
heat

lower flammable limit - ANSWERthe least concentration of flammable vapors in the
air that will burn (lean limit)

upper flammable limit - ANSWERthe greatest concentration of flammable vapors in
air that will burn(rich limit)

smoke, flame, heat, and gases - ANSWERresults of combustion

smoke - ANSWERis the result of incomplete combustion

free burning - ANSWERwhite or light gray smoke

hot fire, lack of oxygen - ANSWERblack or dark gray smoke
station bill assigns fire station and assigned duties - ANSWER-emergency squad
usually musters at emergency gear locker to gather up equipment as required
-master coordinates all activities from bridge
