ANÁLISE DAS CONDIÇÕES DE TRABALHO DOS MANUTENTORES NA REVISÃO DE MOLDES PARA USO EM TERMOFORMADORAS EM EMPRESA DO SETOR PLÁSTICO

Abstract

The plastic sector in Brazil, when compared to the other countries, is growing. It is of the utmost importance that investment in quality of work grows exponentially, just as investment in machinery. The actions aimed at maintainability of the equipment that guarantee the productive process of the large, medium and small industries can cause damage to the health of the maintenance workers. To mitigate these impacts, it is extremely important to analyze the working conditions of this area. This action, coupled with increased process efficiency, can lead to the company's profitability. The objective of this work is to analyze the real work of the repairers in the revision of molds used in thermoformadoras of the plastic sector, from the Ergonomic Analysis of Work (AET). In this way, the existing risks will be identified, and, simultaneously, analysis and proposition of improvements in the industrial maintenance sector. It is a qualitative research, based on a case study, carried out in a company of the plastics sector located in the city of João Pessoa - PB. The demand was verified from the reports of industrial maintenance workers, from the filling of the perception questionnaire, with the presence of pain or discomfort in the lumbar spine, neck and thighs. From the results obtained with the analysis it was possible to identify the ergonomic and accident risks in an oriented way, to carry out the diagnosis of the activity. Among the risks found, we can mention those that bring demands related to ergonomics and others that are directly associated with worker safety. Among them we have the inadequate positioning in the revision of the molds and the risk of mold dropping during the course of the mold to the point where the revision is performed. With all the information made in the diagnosis, it was possible to list improvements, such as the acquisition of a regulatory table with protection, so that the need to use structures to hoist molds does not exist anymore, the elaboration of procedure for the proper training of the worker , among others.
