                                         any other components liquefy. In actual practice, liquid butane
                                         and propane are removed together, leaving behind only ethane
                                         and methane. The mixture of liquid butane and propane is known
                                         as liquid petroleum gas (LPG). Since propane and butane have
                                         many similar properties, there is often no commercial reason to
                                         go to the expense of separating them from each other. LPG is
                                         typically stored above or below ground in large, insulated con-
                                         tainers and shipped in insulated trucks or rail cars.


                                         COMMON USES AND POTENTIAL HAZARDS
                                             Butane, in both gaseous and liquid form, is widely used
                                         as a fuel. Because it is easily stored and transported in small
                                         containers, it is used as a fuel for backpacking stoves, small
                                         space heaters, and portable torches. Butane is also the fuel
                                         most commonly used in cigarette lighters. It may be used in
                                         its pure form or in combination with propane as liquefied
                                         petroleum gas (LPG). Butane is also used as a fuel for larger
                                         household and industrial operations.
                                             In terms of volume, one of the major uses of butane is in
                                         the synthesis of other organic compounds, especially synthetic
                                         rubber and high-octane liquid fuels used in aviation. The gas
