Abstract

In this article, the impact of introducing ergonomic approaches into the occupational safety system on labor safety and labor productivity is analyzed from a scientific and practical perspective. The main purpose of the study is to assess the possibilities of reducing occupational risks and increasing work efficiency by adapting workplaces to the anthropometric, physiological, and psychophysiological characteristics of humans.

During the research process, the initial ergonomic condition of workplaces was assessed, ergonomic interventions were implemented, and their impact on labor productivity and the level of occupational risks was analyzed using statistical methods. The results of the practical study showed that after the application of ergonomic requirements, worker fatigue decreased, the number of errors during the work process was reduced, and labor productivity increased on average by 15 to 20 percent. Correlation analysis confirmed the presence of a strong positive relationship between the ergonomic environment and labor productivity.

The obtained results indicate the necessity of enriching the occupational safety system not only with technical and organizational measures, but also with ergonomic approaches based on the human factor. The article develops criteria for assessing ergonomic conditions, mechanisms for reducing occupational risks, and practical recommendations for implementing the results into occupational safety practice. The conclusions of the study can be applied in making scientific decisions aimed at harmonizing labor safety and production efficiency.
