Aspectos biomecânicos no trabalho de limpeza na torre de ciclones de uma indústria cimenteira

Abstract

The investigative focus of this study is the cleanup work at the tower of cyclones, and it aims to meet the demands formulated by the Department of Health and Safety at Work from a cement company, as well as to find elements which subsidize the negotiations related to the improvement of working conditions in the industry. There has been developed a hypothesis that low back pain complaints were related to physical and organizational characteristics of the job done by industrial operators C, such as the height and shape of the doors and temporal constraints.In order to understand the activity, we have adopted the ergonomic work analysis. Empirical data were obtained from observations and filming of the activities of industrial operators C.The results show that operators are exposed to heat stress, risk of accidents and stereotypical postures, which contributes to increased stress on the spine. The activity analysis has shown operators ensuring the balance between production and safety.At the end of the study it was possible to elaborate suggestions for improvements in order to enable the Department of Health and Safety at Work to begin negotiations with the actors involved and make the necessary modifications.
