Perception level of hazard pictograms by future engineers

In the work environment, as well as day-to-day, the understanding of pictograms of dangerous chemicals is crucial, contributing to the minimization of accidents and the improvement of working conditions. Pictograms are a quick and clear way of identifying hazards, thus promoting a low chemical risk index. The present study aimed to evaluate the visual perception of chemical hazard pictograms by higher education level students of engineering areas, regarding the proper understanding of their meaning. In this study, the method adopted was that of open-ended tests, which is recommended for evaluating the comprehensibility of symbols. The results of this study are indicative of a low level of perception for the chemical risk on the part of the participants. In order to promote greater safety and better performance of these students in future workplaces, it is imperative to invest in their training in the area of occupational safety and health. The future engineer should be taken into consideration in the development of strategies on accidents and occupational diseases prevention.
