The required level of safety of machines and mechanisms is achieved through the use of appropriate safety management systems for industrial equipment, including programmable electronic ones. Such systems usually include a variety of security devices for managing industrial equipment settings. Since electronic control systems are currently considered the most promising control systems in this area, the study of the security parameters of their application support determines the relevance of this study. This study analyses the main requirements of IEC 61508 and IEC 62061 standards for compliance with modern safety requirements of embedded and applied software for electronic control systems of machines and mechanisms. This study proposes an algorithm for step-by-step implementation of software for electronic machine control systems in accordance with basic security standards for both built-in and application software. Testing has been determined as the main method of verification of application software. Based on the results of the analysis, it was found that the specification of security requirements, both built-in and application software, should highlight the necessary characteristics of each subsystem, providing information that allows choosing the equipment that meets existing security requirements. Relevant recommendations are given on the specifics of practical application of these standards.

Purpose: Studying urgent problems in the OSH management field in the in European countries to create effective information and analytical support for the OSH management system. Design/methodology/approach: An analytical review of open sources, a comparative analysis of the legislative framework of different countries and logical conclusions based on existing opportunities at the current stage of development of the country were used to study current problems in the field of labour protection management and find ways to create effective information and analytical support. Improved IS "Vizit" was tested for 2018-2019: to identify undeclared labour, the dynamics of various types of labour violations has been studied; to predict the load of inspectors, the quarterly dynamics of inspection actions was studied; the accumulated statistics were processed using multiple regressions; for 22 enterprises, employees of all levels were remotely trained in labour protection issues. Findings: Information and analytical support for the OSH management system has been developed. On the basis of indirect signs it allows to identify undeclared work cases, to predict the labour inspectors’ inspection activities by quarters, to provide effective distance learning of enterprise employees and labour inspectors. The distance learning system for labour protection was tested at 22 enterprises: the head of the enterprise, the heads of departments and employees of the enterprise passed the training. Since 2018 (start to use of this information and analytical support), the dynamics of inspection actions and various types of labour violations have been monitored. Research limitations/implications: Information and analytical support was tested on the example of Ukrainian labour legislation. However, it can be adapted to the legislation of another country. Practical implications: The proposed information and analytical support using indirect evidences provides an opportunity to identify undeclared work and that significantly reduces the inspection visits number in order to monitor and detect violations of the law; makes it possible to predict the inspection activities and the workload of labour inspectors; contributes to the organizations managers and employees’ effective training, and the inspectors training remotely (and therefore is less costly). Originality/value: A non-standard approach to the identification of undeclared work on indirect grounds using information and analytical support for the OSH management system is proposed.

Labour protection at an enterprise is defined by most economists as a system that greatly expands the ability of enterprises to achieve operational results. Moreover, the role of labour protection as a factor that can intensify production is determined in such a way only in countries with a market economy. The relevance of the study is determined by the possibilities of positioning labour protection as a factor that increases the value of manufactured products, including for countries with economies in transition. The purpose of the study is determined by the need to develop models that make it possible to assess the economic effect of the measures being introduced at enterprises of both the industrial and consulting sectors. The research methods are analytical and methods of modelling economic structures. The study determined that the cost of occupational injuries and occupational diseases, together with the cost-effectiveness of labour protection measures, are an important incentive for employers to take these measures. They were found to be particularly interested in whether the investment in the programme is cost-effective (the effect gives a good return on investment) or economically viable (the financial benefits are favourable). The authors demonstrate that most of the published intervention studies so far have focused on the effectiveness of interventions as opposed to their cost-effectiveness. Allocation of the developed methodological structure makes it possible to determine, this time by quantitative characteristics, the possibilities for structuring and achieving the goals set for the enterprise by the shareholders and production plans. The study defines the limits of using the interests of labour protection as a social structure in combination with the use of production planning methods. Further high-quality research is required to conduct a full economic assessment to be capable of drawing further conclusions regarding the cost-effectiveness of occupational safety measures from an employer's standpoint

The object of this study is the quantitative characteristics of magnetic fields induced during electric contact welding in various ways: contact point, arc-butt, capacitor point, contact-butt continuous, and pulsating fusion. The problem to be solved is the lack of necessary information regarding the electromagnetic safety of these welding techniques. A description of the proposed methodological approaches to determining the levels of magnetic fields, their measurement tools, and methods for assessing their impact on the welder's body is given. Based on the analysis and processing of the acquired oscillograms and spectrograms of magnetic fields, their quantitative characteristics were measured. To determine the general level of the polyfrequency magnetic field arising at contact welding, the proposed generalized indicator of the level of the magnetic field was used. It was established that during contact point welding by a stationary machine, the level of the magnetic field exceeds the maximum permissible value at the workplace in the range of 50–1000 Hz at a distance of 0.3 m from the welding electrodes. When manually welding in this way, the magnetic field level exceeds the permissible level in the frequency bands of 5–50, 50–1000 Hz directly near the electrical cable. Capacitor spot welding with direct current is characterized by exceeding the maximum permissible MP at the workplace in the high-frequency range of 1000–10000 Hz. During arc-butt welding, no excess of the maximum permissible levels of the magnetic field was detected at the workplace. It is shown that the spectral composition and magnitude of the magnetic field signal is determined by the welding technique and the initial parameters of power supplies. Orimani results can be used in the field of welding production and labor protection.

The purpose of this article is to develop methodological approaches to a complex sanitary and hygienic assessment of welding materials based on modern methods of mathematical modeling. An ideological structure of a computerized database is proposed, which would allow to collect and edit data on welding materials and welding modes, to systematize them, as well as to display the necessary user information on the screen by processing various requests. The complex of harmful and dangerous factors accompanying welding processes is analyzed. The method of mathematical modeling of the dependence of the intensity of welding aerosol release on the set of technological factors is given and the necessity of its improvement is argued. The urgency of creating an information-analytical system of complex sanitary assessment of welding materials for the selection of optimal, from a hygienic point of view, welding technologies is substantiated. The advantages and disadvantages of the existing developments of information-analytical systems of managerial decision-making in the welded production are given. The structure and conceptual aspects of creating a new database for the computer system of information support of complex sanitary and hygienic assessment of welding technologies and materials, in accordance with modern requirements of the standard DSTU ISO 15011- 4: 2008.
