Fire Tetrahedron FUEL HEAT OXYGEN TRIANGLE Flammable Liquids Characteristics Vapor : Vapors not liquid that burns Vapor density of most flammables is heavier than air Proportional to Surface Area Pressure increases w/temperature Flash Point is: Lowest temperature at which sufficient vapor is given off to form ignitable mixture Flammable Liquids Characteristics Fire Point: Temperature above flash point in which combustion can be sustained (Auto) Ignition Temperature: Minimum Temperature of heat source to ignite vapor Is the lowest temperature at which it will spontaneously combust Justrite Manufacturing Company LLC 2
