Flash Points of Common Liquids and Gases
          Judged by flash point alone, propane, with a flash point of 156 degrees below zero Fahrenheit, might seem more dangerous than gasoline, whose vapors won’t ignite at temperatures below minus 45 degrees Fahrenheit. However, it’s the combination of flash point, vapor density, flammable range and especially accessibility that makes gasoline so dangerous on an everyday basis. Unlike gasoline, propane is not available in concentrated liquid form where its vapors are easily accessible to a spark or match.
        Turpentine barely ranks as a “flammable” liquid. Other common liquid and gas products, although easily combustible in the event of a fire, are far less likely to produce vapors that can ignite from an incidental source such as a spark or match.
