Some manufacturing processes are accompanied by significant noise and vibration. Sources of intense noise and vibration are machines and mechanisms with unbalanced rotating masses, as well as technological installations and apparatuses in which the movement of gases and liquids occurs at high speeds and has a pulsating character. The modern development of technology, equipping enterprises with powerful and fast-moving machines and mechanisms leads to the fact that people are constantly exposed to noise of increasing intensity. Increasing noise and vibration in the workplace has a harmful effect on the human body. As a result of prolonged exposure to noise, the normal activity of the cardiovascular and nervous systems, digestive and hematopoietic organs is disturbed, and professional hearing loss develops, the progression of which can lead to complete hearing loss. Among industrial hazards, noise and vibration occupy one of the leading places among production hazards. The harmful effects of increased noise levels on the human body are well khown, therefore, the relevance of this problem is obvious.

The purpose of the research – hazard analysis and calculation of the level of occupational risk at the bricklayer’s workplace. The scientific task that was solved in the course of the study was the analysis of the dangers associated with each other by various technological processes during stone work. The result of the study is to determine the level of professional risk by the method of a three-level scale of damage based on the analysis of the main characteristics. For this study, the main hazards in the workplace were identified and categorized. A register has been compiled based on the identified hazards. For clarity of the final data, a table was formed.

Official statistics show that labor activity is accompanied by the presence of various kinds of hazards and harmful working conditions, which are risk factors for injury and the development of occupational diseases of workers. Risk assessment is one of the necessary procedures of the occupational health and safety management system and includes the following stages: identification of all risk-forming factors characteristic of the organisation, compilation of a unified register of hazards, calculation of occupational risks and development of measures to reduce their impact in the workplace. With all the diversity of hazards, there is no unified approach to the development of the organisation's register, and this is an urgent problem, the solution of which will allow a qualitative approach to the issue of calculating and assessing professional risks. The article offers an accessible and practical-oriented method for identifying and developing a unified register of hazards of an organisation, which allows setting the uncertainty parameter of the register, which is an additional coefficient when calculating occupational risk in the workplace.

The main goal of improving working conditions is to achieve a social effect, i.e. ensuring labor safety, preserving the life and health of workers, reducing the number of accidents and diseases at work. Improving working conditions also yields economic results: an increase in profits (due to an increase in labor productivity); reduction of costs associated with compensation for work with harmful and difficult working conditions; reduction of losses associated with injuries, occupational morbidity; decrease in staff turnover, etc. The main document in the normative and technical documentation is the normative act “Occupational safety standards system”.
