Аннотация
In this article, the worker’s physiological workload during the process of opening the lower hatches of semiopenrail freight wagons located on an elevated track was assessed on the basis of sanitary and hygienic standards. Inparticular, taking into account dynamic and static muscle strain, awkward working posture, the height factor, and repetitiveexertion, the worker’s physiological workload was determined for two hatch-opening methods: opening from ground leveland opening while positioned on an overpass. Based on the analyses performed, scientific conclusions were formulatedthat work carried out on the overpass is characterized by higher physiological strain due to a greater share of static load,and that ergonomic optimization and mechanization of working conditions are necessary
