Mapeamento dos riscos da pedreira Britamil-PA e aplicação da metodologia de LAPA (2006)

Abstract

Despite the indisputable importance of mining activity in the Brazilian economy, it is necessary to seek greater control of risk agents, which come to having a disproportionate growth, causing numerous accidents and occupational diseases. Therefore, it is essential that companies in the industry to adopt some tools created for managing risk areas, which allowed greater control of these risk agents present in the business environment. The present TCC sought to build two risk maps, one of the mining and other processing steps, both in the quarry Britamil, located in Eldorado dos Carajás - PA, and the application of the methodology of Lapa (2006 ), which allowed visualization of risks factor in a numeric scale, allowing the construction of a sequence of security measures to be taken in order to reduce them, which are above the moderate, decreasing considerably the possibilities of accidents occur, thereby, contributing way to improve the safety and health of workers . Therefore, were sought in the bibliographies foundations, in order to base the importance of risk management, which entails, thus increasing productivity and reducing revenue losses and expenditure on medical services. After the analysis of the manufacturing operations of the quarry, it was found one of the main problems of the quarry was on occupational exposure of workers to crystalline silica dust, causing a quite considerable chance of these employees come to develop silicosis. In the control room of the crusher, the degree of risk associated with crystalline silica dust was considered intolerable. One reason for the increase was the fact that this operator, despite having respiratory protector, neglecting the use of the same, which demonstrates that in order to reduce the factors for the wealthy class moderates is necessary that the participation of all workers involved in the process. Faced this problem, was proposed some measures that allowed reduction of particulates in the air, as humidification processes, building curtain tree to prevent wind drag, regular inspections at works area, make sure that workers are actually using the protective breathing etc.
