ОСОБЛИВОСТІ ЕРГОНОМІЧНОЇ ОЦІНКИ РУЧНОГО ЕЛЕКТРОІНСТРУМЕНТА

Abstract

Hand-held power tools are an integral part of any manufacturing process. Modern power tools are characterized by operational, consumer, ergonomic and safety properties. These properties characterize its effective adaptability to the relevant production process. But it should also be noted that not taking into account the ergonomic properties: noise load, vibration, tool weight, heating temperature of the working surface of the tool, etc. causes very serious consequences for the deterioration of the health of the employee who uses it. This is especially true for occupational diseases of the circulatory system, nervous system, diseases of the bone and vascular tissue. Object of the study – development of a fast-effective method for assessing the ergonomic risk of hand-held power tools when performing a specific production task Purpose of the study – ergonomic risk when working with hand tools when performing the appropriate technological process. Method of the study – the research method is based on observations and studies of specific phenomena of the process under consideration, as well as the generalization of the results of experimental research and their implementation in practice. Results of the study – the most influential criteria that affect employee productivity when working with hand tools are identified: integrated design ergonomics, load, tool weight, jerk load, tool surface heating temperature, vibration, noise, dust particles during tool operation. For each criterion the corresponding estimation of ergonomic risk taking into account influence on a physical, psychological condition of the worker is proved. A checklist has been developed to determine the level of ergonomic risk according to eight criteria. Keywords: hand power tools, ergonomic risk, indicator, harmful factors, occupational diseases, checklist.
