Análise ergonômica do trabalho florestal em uma empresa de produção de madeira em toras

Abstract

The growing demand for wood and the reduction of native forests has made with that the planting of homogeneous forests of exotic species Pinus and Eucalyptus increase to supply global demand. However, the work of implementation, maintenance and harvesting of planted forests require large numbers of people, especially in areas where activities occur on sloping sites or activities where there is no still technology to replace manual labor. Therefore, to obtain higher quality in work activities, forestry companies invested in technology, in some cases, replacing work stations for modern machines. However, new problems began to appear as a result of the new work situation as, noise, vibration, night work, mental effort, charges for quality and production, work overload, fatigue, isolation and musculoskeletal disorders (MSDs). Thus, to improve the quality of life at work is necessary the implementing an ergonomics program. Because, starting from the ergonomic analysis of work (EWA), this project aims to propose improvements in working conditions minimizing the problems of interface man, machine and environment in the production of wood obtained from planted forests, in silvicultural operations (pruning) and harvest forest. Therefore, in this work have been used three ergonomic tools called RULA method, OWAS and Couto’s checklist, the cutting operation with a chainsaw and pruning have been the activities that showed at greater risk the health of workers and need immediate changes in how they are conducted.
