Análise de risco no descarregamento de metanol

Abstract

This work was developed in order to identify the risks in methanol unloading operation in a company located in the Curitiba-PR metropolitan region. Therefore, it was used the tool Preliminary Pest Risk Analysis (PPRA), in order to classify the risks encountered and suggest recommendations that can minimize or eliminate the risks detected. The basic tool used for the study was the observation, which enabled monitor the entire real-time unloading process, and the interview with the employee responsible for the operation. The results show that there is a possibility of accidents, if a procedure is not followed, and the main causes are the inappropriate use of equipment and individual protection equipment (IPE) and collective protection equipment (CPE) (fall hazard the operator working from a height, explosion hazard), external factors (fire hazard), lack of operator training or even monitoring of their work, verification and conference before starting some operation (risk of trampling), among other causes. The main relevance of the work is based on ensuring that the worker in working environment better and safe so for each identified risk has their level of action and recommendation, which may in the future help correct or mitigate each risk. Thus, this study showed that the company should adopts the PPRA on it analysis, as this is a complementary tool to HAZOP, tool used today as provide more complete results giving the possibility to improve the control, prevention and reduction in accidents at work.
