Medidas preventivas frente a riesgos químicos en la Curtiduría Hidalgo

Abstract

The main objective of this research project was to develop preventive measures against chemical risks present in the production processes of the Hidalgo Tannery through estimation, seeking to protect the health of workers, reduce exposure to hazardous substances and ensure compliance with national and international regulations on occupational health and safety. A quali-quantitative methodology was used, which included the identification of chemical risks by applying a checklist in which the actual working conditions were recorded, the use of safety data sheets (SDS) of the chemical products, for the estimation of the level of chemical risk by inhalation, the UNE-EN 689:2019+AC and NTP 937 regulations were applied to categorize the risk levels. The results obtained showed that substances such as ammonia (Pinh=350), sodium metabisulfite (Pinh=700), relugan gt-24 (Pinh=350), mercury bichloride (Pinh=700) and lime (Pinh=700), 25% of the chemical compounds analyzed presented a moderate risk level, indicating that workers are exposed to chemical risk by inhalation in the areas where these chemicals are used. Finally, we concluded with the preparation of technical guidelines for the substitution of hazardous chemicals and the implementation of localized extraction systems, as well as the selection of appropriate personal protective equipment (PPE) and complementary activities such as procedures for the use and maintenance of PPE, the safe storage of chemicals according to their compatibility and first aid measures in case of accidents.
