The industrial safety system at JSC Russian Railways has been developing for decades. In the new economic conditions, many of its basic principles have been preserved, but new factors have emerged that require scientific analysis, experimental verification, and modern technological tools. In the course of the research, an assessment was made of labour safety situation at the energy sites of electrified lines of railways with particular regard to the use of a removable insulating tower for catenary repairs, assessment of high voltage hazards for employees, peculiarities of construction of fire protection compartments, fire risk calculations. It is concluded that the calculation of an individual fire risk cannot be used as a necessary and sufficiently autonomous basis for substantiating the size of fire compartments. The removable insulating tower carriage and shunt rod developed atRussianUniversityof Transport are presented. Many conclusions have general character and are of universal interest.
