The properties of liquefied gases are considered. The main dangers in their transportation by rail are defined. The exergy values for liquefied gases and their combustion products are obtained. Dependences between energy and temperature, pressure, heat of combustion are presented. The possibility of application of exergy method to the assessment of fire danger of transportation of liquefied gases on railway transport is proved.
