Análise de riscos em estações de tratamento de água e efluentes: caso de uma indústria química da região de Curitiba

Abstract

There are multiple risk factors within the water and effluent treatment units, due to the physical space, infrastructure and the analyses being performed. As such, it is essential that studies be carried out with a view to minimising damage by said risk factors. This study aims to analyse the safety risks to the water treatment plant operators - WTP and waste water treatment plant - WWTTP. Thus, PRA - Preliminary Risk Analysis was carried out in a chemical plant, in order to identify the risks during the operational activities of the units. Therefore, technical observational visits were made which allowed us to evaluate the conditions to which employees are exposed. It was observed that the operators of the three shifts are subject mainly to chemical risks, such as exposure to chemicals, dust, fumes, mists and gases; biological risks during the collection of mud samples and physical risks, i.e. heat, cold and exposure to non-ionizing radiation (sun), as the activities are carried out in open units and without cover. After the qualitative risk assessment we note that, in general, the proposed method is an effective tool in the analysis of potential risks and the illustration of potential dangers within said workplace. In conclusion, it was found that the study was a satisfactory method of risk diagnosis, management within the workplace and can thus be used in the process of seeking preventive measures to ensure that the frequency and/or severity of the occurrence of accidents involving employees, are reduced.
