The methodology known as the workers' model was used to design risk maps in a study performed in the food-processing industry in Pelotas, in the State of Rio Grande do Sul in southern Brazil. The various types of occupational risks were initially represented by geometric figures, with a size gradient to represent intensity. Joint investigation of these icons showed that they had little meaning for the workers. In addition, risks from a same group (physical, chemical, etc.) but with different impact on health were grouped, thus missing the specificities of exposure. As an alternative, and starting from workers' own risk perceptions, a set of risk icons was developed. The study was done in three steps involving sixty workers, who proposed and selected the most suitable symbols, which were subsequently printed on stickers using silk-screen so that the workers could glue them on the risk maps. Each risk is represented by one icon, and intensity of exposure is defined by color. This paper presents the icons and the process involved in designing them.
