Improvement of the safe work system

Abstract

Purpose. To improve the approach to the development of a safe work system, one of the important elements of the occupational health and safety management system (OHSMS) of employees at an enterprise. Methodology. The research is based on the Safe Systems of Work, which combines the content of safe procedures, which are determined taking into account the content of the workers production task when performing production activities, his/her competence in understanding the technological process and characteristics involved technological equipment. Findings. To reduce occupational diseases and industrial injuries at enterprises, it is proposed to implement the Safe Systems of Work (SSW) of 5 steps: analyse, summarize, anticipate, support, improve, which will make it possible to identify occupational risks (OR) and justify the feasibility of reducing their impact on the worker during the performance of production activities. For the implementation of each step, a corresponding procedure is provided, which allows ensuring their implementation. It is proposed to carry out the OR evaluation procedure according to the Tree Trunk Analysis model, which is a section of the trunk of a tree divided into six parts which characterize the dangerous factors that affect the activity of the employee, the functioning of the technological equipment and the environment. A feature of the proposed approach is the establishment of zones of interaction between the following components of the proposed SSW: the worker and technological equipment, the worker and the environment, as well as the environment and technological equipment, which characterize the specified external and internal factors of influence on the SSW. Originality. The approach to the organization of SSW to reduce the level of OR during the performance of production activities has been improved based on the improvement of the OR management process, the identification of external and internal dangerous factors that affect the level of OR, the probability of the occurrence of a dangerous event and its degree of severity, taking into account changes, over time, in the conditions of performing professional activities: during stable work, during an emergency situation, during an accident and during martial law. Practical value. Improved labour protection instructions or maps of safe production processes can be applied at enterprises with the aim of better perception by employees of labour safety requirements and improvement of document flow at the workplace.
