Gerenciamento de riscos de segurança através da aplicação de ferramentas lean: um estudo de caso em uma mineradora no Sudeste do Pará

Abstract

The work safety is a vital preocuppation to any organization and most industries work with goals to achieve zero accidents, however it is very difficult to reach this result due to the large quantity of present risks in the operational area. There is a need to apply methodologies that help in the identification and management of these risks to act in a preventive way against accidents; the Lean Thinking may be one of them, because the solution that it offers focus on the source of risks elimination. This work followed employee's exposure to the security risk at a mining company in the city of Parauapebas-PA, in the sub-assembly workshop, more precisely in the Motorized Wheel Reform’s cell (for six months). The objective was to apply a new method to address these problems, using lean tools, to solve these problems through the A3 methodology, as well as the management of these risks. The actions were divided into four stages: follow-up in the factory floor; construction of the risk prioritization matrix; elimination of the most critical risk; and the implementation of a risk management and resolution system. All this process besides increasing employee’s protection serves to demonstrate the applicability of lean thinking in work safety. Finally, the implementation of these tools made possible a change of mentality in the employees of the company, since they understood the purpose of a preventive action regarding the safety deviations, supported by the presented methodologies.
