Introduction. The article considers the problems of industrial injuries and accidents at gas supply facilities. Hazardous production facilities are characterized by an increase in accidents and injuries among workers. The article considers the peculiarities of occurrence of accidents and injuries in the operation of hazardous production facilities.

Problem Statement. The purpose of the study is to analyze the statistics data and the materials of investigation of accidents and emergencies in hazardous industries, to determine the cha racteristic causes of injuries at work.

Theoretical Part. The statistics on accidents and injuries during operation of gas facilities provided by the Federal State Statistics Service are used as basic information.

Conclusion. The results of the analysis show that the main causes of accidents and emergencies are the causes associated with the human factor and equipment malfunctions. In order to improve safety and prevent injuries among workers, it is necessary to introduce an integrated approach and risk ass essment, which will take into account all the factors and conditions that contribute to the occurrence of accidents and injuries at gas supply facilities.

Introduction. In order to determine the height of the rise of the polluted substances above the source of the pollution, it is important to know the exact distribution of the gas plume.

Problem Statement. The determination of the dust concentration in the working area of asphalt concrete plants should take into account the assessment of the concentration of harmful substances in the working area of the asphalt concrete plant. The study is the analysis of methods for determining the effective height of the pipe, taking into account the dispersion of emissions in the working area.

Theoretical Part. The paper considers the dependences of the estimation of the initial rise of the gas jet, proposed by Berland, Holland, Briggs, and the specialists of the Tennessee Valley. The value of the initial rise of the impurity jet depends on the moment of the amount of gas movement, the thermal power of the wind speed carrying the jet, and the conditions of thermophoresis. The paper presents the comparative graphs of the calculation of the level of the initial rise of the gas jet at different rates of gas exit from the pipe and constant wind speed.

Conclusion. The method of taking into account the initial rise of the heated gas jet gives us better convergence in the calculations of the maximum surface concentrations of harmful substances and in the estimation of distances to them.

Introduction. The article discusses the problems of limited assessment of occupational risk using the existing Fine-Kinney method, which does not take into account the results of a special assessment of working conditions, therefore the authors propose an improved methodology for assessing occupational risk taking into account the working conditions indicator.

Problem Statement. The purpose of this study is to analyze the existing methods of assessing professional risks, analyze the labor protection system at the drilling enterprise, and develop a methodology for assessing professional risks for the drilling enterprise.

Theoretical Part. The existing methods for assessing professional risks and the enterprise standard were used as basic information.

Conclusion. The improved technique will reduce the degree of risk, prevent accidents at work and generally be used at other enterprises.

Introduction. Risk assessment is an integral initial stage of the risk management procedure aimed at reducing damage to the health and life of employees. Currently, the legislation does not establish uniform concepts and criteria for assessing occupational risk. Scientific literature presents a variety of approaches and methods for assessing occupational risk from harmful and dangerous factors of industrial activity.

Problem Statement. It is necessary to develop a model for assessing occupational risk in the units of the Federal Fire Service of EMERCOM of Russia, which allows us to take into account the likelihood of harm to the health of an employee as a result of exposure to harmful and (or) dangerous industrial factors and the severity of health disorders as a result of such exposure.

Theoretical Part. For the assessment of occupational risk in the units of the Federal Fire-Fighting Service of EMERCOM of Russia, we take the definition of risk established by the National Standard of the Russian Federation GOST R 12.0.010-2009 "Occupational safety standards system. Occupational safety and health management systems. Hazard and risks identification and estimation of risks". The assessment of the probability of causing harm to the health of an employee was carried out using the following indicators: the frequency of injuries, the frequency of death, the frequency of disability. The severity of health disorder was assessed through the indicator of labor loss by personnel from health damage.

Conclusion. The paper considers various methods for assessing occupational risk from harmful and hazardous factors of industrial activity. A mathematical model is proposed for assessing the risk of health damage in the units of the Federal Fire Service of EMERCOM of Russia on the principle of labor loss by personnel from various types of health damage. Its values were calculated for employees of the Federal Fire Service of EMERCOM of Russia for 2015-2019.

Introduction. Currently, there is a logistic problem in container transportation technology related to the transportation of empty freight containers, as returnable containers, since an empty container takes up as much space as a full one. A promising direction for solving this problem is the introduction of folding cargo containers. A disadvantage of this approach is the likelihood of injury to the maintenance personnel, which must be inside in the process of folding and unfolding.

Problem Statement. The objective of this study is to study the conditions for increasing the safety of preparatory work due to the design of the container, the main feature of which is the ability to realize the effect of functional self-adaptation to working conditions.

Theoretical Part. This approach allows us, when folding and unfolding, to balance the changing reactions from the own masses and the moments of its moving body parts by means of the corresponding lockable gas springs. Gas springs connect leading links and driven kinematic chains thereby ensuring that their movement in a given speed mode on the entire trajectory is independent of the speed of the driving link. For the practical implementation of the proposed design solution, the paper presents a general method for the synthesis of an adaptive controller of the container mechanisms in the process of folding and unfolding its moving parts.

Conclusion. Testing of the container showed that the effect of functional self-adaptability is quite well implemented along the entire trajectory of the container elements without the use of external lifting mechanisms.

Introduction. Growth of cities and, accordingly, highways influences the quality of air, soil and water resources considerably. Dangerous emissions from cars in the form of sulfur compounds, nitrogen and carbon oxides, acid rain negatively affect people's health every day. In this regard, great importance is attracted to the transportation process optimization. One of the main problems of the transport and logistics services market is the transportation of empty cargo containers as returnable containers, which leads to unjustified fuel costs, labor resources, depreciation of vehicles, road congestion, and has a huge impact on the environment. Within the framework of the National Technology Initiative, approved by the Presidium of the Presidential Council for Economic Modernization and Innovative Development of Russia in 2018, in terms of the priority market direction — "Transport and logistics services" — a solution to the environmental problem is proposed through the use of smart automated containers-transformers equipped with an information system for remote administration, scenario management and mobile applications.

Problem Statement. It is necessary to develop a project that will eliminate technological barriers and optimize transport and logistics services. The implementation of this project should reduce the time of cargo delivery: loading/unloading, empty runs, breaks in work, optimize the delivery path, using newly created mobile applications based on modern high-level programming languages.

Theoretical Part. The SmartBoxCity container-transformer is a part of an information system that includes server and client software. Data exchange with the server is based on the information from the database on the states of the elements of the SmartBoxCity system. "Yandex. Routing" calculates routes and optimizes the operation of vehicles. The movement of motor vehicles is on "closed" optimal routes. Platooning in urban environments takes into account empty and loaded containers in real time, taking into account the dynamics of data.

Conclusion. A practical solution to optimizing the activities of transport companies is proposed, which reduces the time for loading/unloading up to 30%, the share of empty runs up to 25%, and logistics costs for transporting empty containers up to 75 %. The organization of platooning creates conditions for optimizing urban mobility, saving fuel, and improving the environmental situation.

Introduction. The article deals with the problems of analysis and assessment of the safety level of hazardous production facilities of port facilities that have a negative impact on both the environment and the personnel working at the facility. Objects of this kind are referred to the first class of hazard; therefore, they require a comprehensive assessment of their resistance to emergencies in terms of the likelihood of their occurrence in specific industrial conditions.

Problem Statement. The objective of this study is a comprehensive analysis of the safety level of the most vulnerable areas of the technological process of port activities.

Theoretical Part. The results of a scheduled inspection of the AO “Ust-Donetsk Port” conducted by the Federal Service for Supervision of Natural Resources were used as basic information.

Conclusion. Based on the calculation results, it was found that the probability of an emergency for the most dangerous scenario is 2.4×10-8 and corresponds to the acceptable risk zone.

Introduction. Environmental contamination by vehicles is one of the main and important questions. Road transport is on the first place by quantity of harmful substances released into the atmosphere. The railway transportation pollutes environment by 3 %, planes — by 6 % from the total amount of pollution. The rest is motor transport. As it is known, the maximum quantity of harmful substances is thrown out in an idle mode of work of the engine, i.e. at idle times at stops. The improvement of an ecological situation on transport highways is possible by the optimization of movement of city public transport.

Problem Statement. The task was to develop a project that allows you to eliminate violations of the dispatch schedule of city buses. It is proposed to use the computer program "Line Dispatcher" developed by the authors and a mobile application to monitor the compliance with the dispatch schedule.

Theoretical Part. The field observations carried out on one of the most intense sections of the transport arteries of Rostov-on-Don — the ring at the intersection of Vavilova and Koroleva streets — show how many buses produce harmful emissions only on one section, stand idle at the stop, do not fulfill the dispatching schedule, and, thereby, worsen the environmental situation in the city. The authors have developed a computer program "Line Dispatcher", which allows you to: download a map of the city or a district, the information about the stops on the route and the timetable; choose the desired route; monitor the movement of the bus according to the schedule. The mobile app can be installed on any smartphone of the driver and dispatcher.

Conclusion. A practical solution is proposed to optimize the activity of public transport, which will eliminate downtime at stops due to electronic control of the dispatch schedule and reduce emissions of harmful substances by urban public transport.
