Riscos e medidas preventivas na operação de injetoras plásticas

Abstract

Accidents with plastic injection machines represent a serious safety problem in the plastic production chain, which has become increasingly frequent with the advancement of technology. The present work seeks to evaluate the operation process of a plastic injection molding machine, in order to map the environmental risks to which workers are exposed, as well as to suggest preventive measures for its control and elimination. To this end, all stages of the work of a plastic injection molding machine operator were described, the concept of environmental risks was presented, and a qualitative survey was carried out which enabled the description and analysis of the risks through a Preliminary Hazard Analysis (PHA) and, later, apply the Method of Analysis and Trouble Solution (MASP) to identify the root causes of the problems found in the PHA and the suggestion of effective preventive measures. From the results obtained with the work, it was demonstrated the effectiveness in the use of the analysis methods and, consequently, the need to adopt preventive and corrective measures, in order to avoid accidents in the plastic injection process.
