Colheita de madeira danificada pelo vento: carga física de trabalho e risco de LER/DORT aos trabalhadores

Abstract

This study carried out an ergonomic evaluation of the workers of the harvest of wood damaged by the wind, in the State of Minas Gerais, in order to determine the ergonomic risks to which workers were exposed during the development of these activities. The physical workload by means of heart rate and the risk of RSI/WRMD by means of the simplified evaluation of the biomechanical factor in the risk for work-related upper limb musculoskeletal disorders were evaluated for each of the activities developed. The results showed that the work environment provided different ergonomic risks to workers. In the evaluation of the physical workload, all the activities evaluated were above the recommended limits of cardiovascular load, which exposes the workers to the risk of developing occupational diseases, being necessary the reorganization of the work. The analysis of the risks of the emergence of RSI/WRMD also indicated the need to reorganize the work, since the execution of the activities offered a high risk of injury to the worker, mainly due to the high frequency of repetitive movements associated with the static effort And to the handling of heavy loads, factors present in the routine of harvesting of wood damaged by winds.
