APPROACH TO THE IMPLEMENTATION OF THE TOPOGRAPHICAL METHOD OF ANALYZING WORKING CONDITIONS THROUGH THE DETERMINATION OF PATTERNS OF REDUCING THE LEVEL OF INDUSTRIAL RISKS

Problem statement. In Ukraine there is an increasing awareness that accidents and various diseases associated with professional activity have a detrimental effect not only on the lives of individual workers, their families, but also on the socio-economic well-being of society as a whole. A methodical approach to the use of risS.k-oriented approach to the implementation of topographical method of occupational traumatism forecasting in modern conditions, the basis of which is an assessment of occupational risks for the occupational health and safety management system and the Schuchart-Deming cycle of continuous improvement, is considered. Weber-Fechner and S. Stevens laws were taken as the basis for calculation of occupational and industrial risks depending on the parameters of the working zone, taking into account the time of workers' stay in the zone of hazardous factors. An algorithm for converting environmental parameters into an index of occupational risk was developed. There was performed an analysis of the map of working conditions by the results of the certification of some working places of the regional branch "Osnova Locomotive Depot" of the JSC "Ukrainian railroads" regarding the probability of the hazardous factor action, and the probability of a worker being in the zone of its action. At that, it was necessarily taken into account that action of harmful and hazardous industrial factors is not limited to the working area, but spreads in space in accordance with the established laws. Such approach allows to estimate mutual reinforcement of harmful and hazardous factors effect in space and to determine the most hazardous zones in the workshop premises. Purpose is to substantiate the application of risk-oriented approach to topographical method of industrial injuries prediction. Conclusions. The results obtained testify to the mutual increase in the harmful effects of the factors of the working environment and the working process on the workers of the diesel and welding departments. Application of the proposed approach makes it possible to estimate the values of potential industrial risk at any number of harmful and hazardous factors at workplaces, taking into account their mutual influence, to determine the zones with the largest levels of industrial risk between workplaces and at any distance from them to determine the optimal and safest routes of workers' movement through the shop territory.

ANALYSIS OF PRODUCTION RISK FROM CRUSHES OF ROCKS AT EXCAVATION SITES, TAKING INTO ACCOUNT WAYS OF PROTECTION

Purpose. To assess the production risk of rock collapse in a deep coal mine to identify hazards in the workplaces of the excavation site, taking into account different methods of protection of workings. Methods. A comprehensive approach was used, which included: analysis and generalization of known research; expert evaluation; use of the basic provisions of probability theory and set algebra (Venn diagrams), the method of estimating the production risk of Fine-Kinney; processing, analysis and interpretation of the obtained results. Results. Problems and sources of industrial risk from rock collapses during maintenance of workings, risk-forming factors that contribute to the threat of dangerous events at the excavation site are analyzed. The decision-making model is considered, which is based on the description of situations when the production risk of the dangerous factor “landslides and collapses” in the maintenance of preparatory workings depends on the result of choosing an alternative method of protection of the retractable lane. For excavation sites under the same mining and geological conditions for all workplaces, the probability of receiving consequences from dangerous events due to uncertain conditions of their implementation has been established. It is fixed that the realization of this production risk is influenced by low reliability and inefficiency of the practiced methods of protection of excavations. Risk analysis is defined as the systematic use of available information to identify hazards in the maintenance of long workings. Novelty. A model for monitoring the production risk of rock collapses in excavations of deep coal mines is proposed, which allows assessing the dynamics of the threat at the stage of technical decisions related to the choice and justification of the method of protection of workings taking into account the interaction of risk factors. Practical significance. When formulating measures to reduce the risk of dangerous events at the excavation site, it is necessary to take into account that the production risk of rock collapse while maintaining the workings depends largely on the method of protection and effectiveness of technological measures.

PRODUCTION RISKS IN THE OIL - GAS INDUSTRY

This article suggests ways to quickly assess the state of labor protection and ecology by calculating a number of indicators of industrial risk based on the information available in the modules for assessing labor protection by indicators of industrial risk. The efficiency of using the software proposed by the authors for the occupational health and safety management system based on a specific task from the modules "Personnel", "Events", "Equipment" and "Ecology", consisting of four main modules, is proved. In addition, this paper compares the matrix methods of risk assessment in the coordinate system "probability of an event or consequences of an event" of prevention and assessment of occupational risks for employees used in domestic and foreign practice in the occupational safety management system.Work on identifying harmful factors of accidents during the extraction, use and transportation of raw materials at industrial enterprises and assessing compliance with the requirements of the standards of the Republic of Kazakhstan should be carried out continuously. The main goal of the labor protection service is to create safe working conditions for employees at industrial enterprises, as well as to prevent occupational diseases of employees. In this regard, a system of accounting, analysis and assessment of the state of labor protection, as well as labor safety management, should work.

Improvement of the approach to hazard identification and industrial risk management, taking into account the requirements of current legal and regulatory acts

Purpose: Improving the systematic approach to planning and rationalizing labour protection measures at oil and gas enterprises, based on the results of hazard identification and industrial risk assessment. At the same time, the main task of the risk management process is to ensure the rights of employees guaranteed by the current legislation, namely, to create proper, safe and healthy working conditions. Design/methodology/approach: A comparative legal method for identifying the features of European and Ukrainian legislation in the occupational safety and health field; a structural-logical method for determining the main directions for the further development of the occupational safety and health management system at enterprises; analysis and generalization of well-known scientific results on the research topic; statistical analysis to identify the relationship between the industrial risk' level and various factors that may affect its value; applied systems analysis and mathematical modelling method for new methodological approaches' development to assessing of hazards' likelihood and their consequences' severity were used. The basis for improving the systematic approach to planning and rationalizing labour protection measures is based on the standard IEC 61882:2001. The statistics are taken from the "Messages" information system, which operates in the State Service of Ukraine on Labour and is designed to collect and process data on occupational injuries. Findings: An analysis of the current legislative and regulatory acts showed promising directions for their improvement. A mathematical model for scoring industrial risk is proposed, which takes into account the relationship between industrial risk and preventive measures and the time of their implementation. The calculation system developed on the basis of the proposed model provided a reduction in the time for processing data and calculating the values of industrial risks by 20...25%. Research limitations/implications: Statistical data on industrial injuries at enterprises of the oil and gas industry of Ukraine for 2018-2019 were used. Practical implications: Implementation of the proposed systematic approach to the organization of occupational safety and health management at enterprises has shown its simplicity and effectiveness, which can induce employers to finance reasonable and timely preventive measures. Originality/value: The method has been improved by decreasing the discreteness step in the assessment of industrial risk components, which has increased its accuracy; by developing a mathematical model for calculating the probability of a hazard, taking into account the frequency with which workers are exposed to danger, which eliminates the need to involve experts for an expert assessment at this stage.
