The information was obtained through surveys of workers and also through checklists on equipment conditions, use of EPPs and manufacturing procedures. The main risk factors in the bonding process were identified through chemical risk matrices that followed the format of the Ministry of Labor Relations of Ecuador. These factors were prioritized through the Ishikawa diagram to find the root cause of the problem. It was complemented with measurements of toluene and hexane concentrations in the upholstery area; the weighted concentrations were determined, a risk index for the toluene hexane mixture of 0.21 was obtained and a chemical risk was determined by inhalation under. However, since the risk is present, the data obtained served to design the prevention plan for the area. which considers procedures and measures focused on the source of contamination, the means of propagation and the exposed worker.
