The textbook "Designing of machine-building workshops and sites" is a publication created on the basis of a modern methodology for designing production systems with specified properties, using an automated design system. Since the main structural units of the machine-building enterprise are mechanical and Assembly shops and sites, so they are paid special attention in the textbook. The theoretical basis of the discipline blended with a large amount of calculations of stalemate machining and mechanical Assembly processes, personnel, production prompdy and examples of designing the different purpose areas.

Introduction. Adverse effects of environmental factors can cause dysfunction of organs and systems, hormonal dysfunction, genetic disorders, which can adversely affect the health of future generations. The aim is to study occupational risk factors and assess their impact on the health of male workers of machine-building enterprises, to develop preventive measures. Material and methods. The working conditions of 318 male workers of the main professions of the machine-building enterprise (miller, locksmith, electric and gas welder, turner, caster, etc.), having occupational contact with harmful occupational factors, were studied in comparison with 148 employees of the control group. Epidemiological, socio-hygienic, statistical and risk calculation methods were used. Results. 68.2% of respondents were found to have occupational contact with cutting fluid, 24.3% contact with chemicals, 14.4% - with heavy metals, 66.2% of respondents work in conditions of noise exposure, 40.1% - local vibration, 22.3% - in conditions of hypothermia, 14.4% - in conditions of overheating. Excess of maximum permissible concentrations of benzo(a)pyrene, aerosols of mineral oils, epichlorohydrin was detected in the air of the working zone. At workplaces, there were excess levels of noise, general vibration, thermal radiation. The impact of harmful occupational factors in the workplace was established to create a high risk to the health of workers. Conclusion. Working conditions of workers of the machine-building enterprise are mainly estimated as harmful. Critical organs and systems for the development of occupational pathology were identified, the high carcinogenic risk from exposure to benzo(a)pyrene was revealed. Employees of the machine-building enterprise were shown to have a high risk of oncology, respiratory diseases, central nervous system diseases, pathology in offspring. As a result, risk groups were formed and targeted preventive measures were proposed, including monitoring of the health status of high-risk groups, occupational selection, and medical examinations.

In the absence of uniform and unified requirements for the assessment of industrial risks at an enterprise, the system approach remains the only tool for a comprehensive assessment of the workplace safety. Implementation of Occupational Safety and Health (OSH) system involves identifying, analyzing and reducing risks at the workplace. The purpose of the article is to calculate the minimum expenses for occupational safety measures and minimize production risks identified through the developed procedure for analyzing the hazards of the machine-building enterprise. The research methodology is based on the integrated use of qualitative and quantitative approaches to risk assessment, namely, structured assessment and integral assessment using the “rucksack problem” optimization model. The study identifies the risks that are most common and the most serious ones. The procedure of risk reduction is proposed, which is to determine the minimum costs for achieving each of the integral assessments for the machine-building enterprise. The practical value of work consists in the ability to directly apply the developed methodology for risk assessment at the enterprises of the machine-building industry, and to easily adapt the risk assessment procedure to other conditions.
