This article presents a conceptualized analysis of technology-related risks for a transportation safety system. It also considers its subsystems that impact safety. The scheme developed allowed defining the key factor influencing transport safety through accounting various destabilizing impacts. The authors claim that the human factor is the key one, which is especially true for locomotive crews responsible for transportation. Locomotive crew working conditions are described in a visualized combination of negative effects people suffer in an engine cab. Based on the statistics collected and analyzed, the article presents specific occupational diseases of transportation workers. The dynamics of mental capacity and the state of the cardiovascular system of locomotive crews were analyzed using the WAIS test. The research results can be used in the practices of the Russian Railways to facilitate the efficiency and coherence in decision making related to labor safety.

Ensuring safety at work largely depends on the quality of research on the factors of the working environment and the assessment of working conditions carried out at the workplace. The scientific paper deals with the problem of equipment for testing laboratories that control harmful production factors. In the absence of an integrated approach to the selection of instrumentation, when equipping a laboratory, there are costs associated with unjustified financial costs and incomplete functionality of the purchased equipment. At present, there are no convenient methods for practical use of choosing the instrumental support for instrumental control of harmful and hazardous production factors. To solve this problem, an approach is proposed to the choice of measuring equipment for measuring harmful production factors, which is based on the method of expert assessments. The results of studies of the application of the expert method to determine the possibility of using a group of devices for assessing physical and chemical factors in the control and monitoring system of harmful factors at the workplaces of a machine-building enterprise are presented. Information on the implementation of the obtained results of the implementation of the expert methodology in the selection of instrumentation in the management system of testing laboratories performing work in the field of labor protection and environmental safety is presented. Based on the results of the implementation, it can be concluded that the proposed approach to the selection of instrumental equipment based on the expert method is universal.
