Avaliação ergonômica do processo de mensuração florestal

Abstract

This study carried out an ergonomic evaluation of workers in eight forest mensuration activities in the State of Minas Gerais. For each of the activities developed, the physical workload, the biomechanics, the risk of RSI/MSDs and environmental factors noise, vibration and thermal comfort, in order to determine the ergonomic risks to which workers were exposed during the development of these activities were evaluated. The results showed that the studied workplace provides different ergonomic risks to workers. In evaluating the physical workload, only the activities of the stacking factor determination and the wood physical inventory were within the recommended cardiovascular load limits. Biomechanical analysis indicated that the rigorous volume determination and collecting wooden disks exceeded the recommended load limit. The activities of rigorous volume determination and soil collecting have been considered as with great risk of developing RSI/MSDs. The thermal overload was the environmental factor that presented greatest ergonomic risk to workers in all activities, followed by the noise in the activities of rigorous volume determination and collecting wooden disks.
