O transporte de correia transportadora é um método de transporte frequentemente preferido no transporte de matérias-primas de instalações industriais. Os principais componentes do sistema frequentemente sujeitos a avarias são correias, tambores, sistemas de rolos e sistemas de tambores tensores de correia. Dentre esses componentes, as quebras de correias são rupturas de correia por corrosão, incapacidade de rotação por corrosão e poeira em cilindros e falhas mecânicas em sistemas e componentes de tambores. Neste estudo, a avaliação de risco foi realizada em prováveis riscos devido a avarias e falhas em uma instalação de transporte ruim. Os acidentes ocorridos na indústria são considerados para especificar os riscos. Na primeira etapa do estudo, foram empregados modos de falha e análise de efeitos. A partir dos resultados do FMEA, foi realizada a análise da árvore de eventos para cada risco a fim de apresentar e diminuir os graus de severidade dos riscos.
