The aim of the study is to develop and test an improved system for categorizing employees by working conditions, taking into account the concept of green workplaces. The empirical basis of the study is based on the example of a large industrial enterprise, the phosphorus plant of the Republic of Kazakhstan, where 41 professions were included in the analysis. The data of workplace certification, indicators of the severity and intensity of the labor process, as well as the results of medical examinations, temporary disability certificates, and information on occupational diseases of employees for the period 2019-2023 were used. The methodological framework includes a comparative analysis of the general hygienic assessment of working conditions and employee health monitoring data using a risk-based approach. The categorization was carried out by classes of working conditions (CWC 1-4), which made it possible to compare the formal results of the certification with the actual state of health of the staff. The main results of the study showed that according to the initial hygienic classification, 4 professions were classified as class 3.1 (moderate degree), 27 as class 3.2 (high degree), and 10 as class 3.3 (very high degree). After the revision, taking into account medical data, 12 professions retained the same class, and for 25 professions it was changed, including confirmation of class 2.4 (very high degree) for three professions. The most unfavorable occupational risk profile is established for the professions of gas purification apparatus, charge workers, granulation and drying apparatus, electricians, electric and gas welders, and repair fitters. The practical significance of the work lies in the fact that the proposed categorization model not only captures the level of occupational risk, but also forms the basis for targeted preventive measures, equipment modernization, automation of the most dangerous processes, and the development of a medical monitoring system. The introduction of the category of green workplaces (CWC 1-2) into the national classification makes it possible to form a balanced occupational safety system that integrates the tasks of reducing harmful factors and maintaining a safe working environment.
