What are the conditions fuel (material that acts as a fuel)
needed for a fire to sources of ignition (chemical, biological, or physical)
occur? oxygen

-only vapors burn
-liquids and solids must first be vaporized
Fuel -tendency of a substance to vaporize is an indication
of its ability to burn
-liquids vaporize more readily than solids
-you can have oxygen, heat, and fuel in the same
place and still not have a fire
Chain reaction -fuel and oxygen relationship must be balanced (i.e. in
the flammable range)
-heat must be sufficient to bring fuel to its ignition
-the lower temp that a liquid can give off sufficient
gas to form a flammable gas mixture near the surface
What is a flash point (of a of a liquid
liquid)? -lowest temp at which we can have fire
-fire flashes across surface given sufficient oxygen
and an external source of ignition
-just above the flash point, liquid gives off flammable
What is a Fire point? vapors rapidly enough to support continuous
combustion
-substance starts to burn
What is ignition
-heat from external heat source
temperature?
-auto-ignitio, no external source of ignition needed
vapor generated ignites without any outside ignition
What is auto ignition?
source
What is vaporization? rate increases with temperature
heat is generated by a chemical action within a
What is spontaneous substance and this continues until you have ignition
combustion? (usually begins with oxidation and combines oxygen
and gives off energy in the form of heat)
What is lower flammable the least concentration of flammable vapors in air that
limit? will burn
What is upper flammable the greatest concentration of flammable vapors in the
limit air that will burn
