Quantificação de riscos em torno mecânico horizontal

Abstract

One of the most used equipment in the metallurgical industry is the horizontal lathe. Because this equipment has been present in the industry for decades, older machines do not have design guidelines or devices to minimize or eliminate the risks that exist in their operation. The indices of work-related accidents arising from the risks generated by these machines show that the attention of companies is increasingly demanded in order to avoid the occurrence of further accidents. Therefore, it is necessary to identify the risks that the employees involved are exposed, quantify them and classify them. In this work a case study is carried out in which the risks that a horizontal lathe generates to the worker during its operation are identified. The risks are quantified and classified in order to suggest whether some task is needed to mitigate them through the risks analysis methodology called HRN (Hazard Rating Number). From the analysis and classification of the risks, it is noticed that the most significant risks are related to the moving parts of the equipment, and in order to minimize them, it is recommended to install protections.
