Foi realizada uma Análise Ergonómica do Trabalho (AET) para compreender as condições de trabalho dos trabalhadores de uma unidade fabril pertencente à indústria metalomecânica, em Portugal. Os objetivos do estudo foram: caracterização da indústria metalomecânica quanto ao risco de desenvolvimento de lesões músculo-esqueléticas (LME), caraterização da sintomatologia músculo-esquelética autorreferida pelos trabalhadores, identificação dos fatores de risco, e definição de um plano de ação para mitigar os problemas identificados. Para avaliar e qualificar o risco de desenvolver LMERT, diferentes métodos, como Rapid Entire Body Assessment (REBA), Rapid Upper-Limb Assessment (RULA), Revised NIOSH lifting equation e Revised Strain Index (RSI) foram usados, para acomodar as especificidades de cada tarefa. O software ErgoWeb EnterpriseTM foi utilizado para aplicar os métodos acima mencionados. Todos os trabalhadores (N=18) concordaram em participar do estudo. Dez postos de trabalho foram analisados e avaliados. Houve uma associação positiva entre as exigências de trabalho e a sintomatologia autorreferida, em várias regiões do corpo. Considerando os métodos de avaliação postural, todas as tarefas apresentaram risco de desenvolver LMERT (nível de risco > 2). A aplicação do método de avaliação de movimentação manual de cargas (MMC) evidenciou que as tarefas apresentavam risco de desenvolver lesões ao nível da coluna lombar (IL > 1). Todos esses resultados mostram que investigações e medidas para melhorar as condições de trabalho devem ser realizadas num futuro próximo. Por fim, foram apresentadas propostas correti
An Ergonomic Work Analysis (EWA) was carried out to understand the working conditions of workers in a factory unit making part of the metalworking industry, in Portugal. The objectives of the study were: characterization of the metalworking industry regarding the risk of developing musculoskeletal disorders (MSDs), characterization of musculoskeletal symptoms (MSS) self-reported by workers, identification of the risk factors concerning each task assessed, and definition of an action plan to mitigate the identified problems. To assess and quantify the risk of developing MSDs, different methods, such as Rapid Entire Body Assessment (REBA), Rapid Upper-Limb Assessment (RULA), Revised NIOSH lifting equation and Revised Strain Index (RSI) were used, to accommodate the specificities of each task. The ErgoWeb EnterpriseTM software was used to apply the above-mentioned methods. All workers (N=18) agreed to participate in the study. Ten workstations were analyzed and assessed. There was a positive association between work demands and MSS in various body regions. Considering the postural assessment methods, all tasks presented a risk of developing musculoskeletal injuries (Risk level > 2). Also, the application of the manual handling of loads assessment method highlighted that the tasks presented a risk of developing injuries at the level of the lumbar spine (IL > 1). All these results show that investigations and measures to improve working conditions must be carried out in the near future. Finally, corrective proposals were presented focusing on two complementary areas of action, organizational measures and technical measures.
