Analysis of noise, lighting and hazard index in the handling of chemical agents in the workshops of the Faculty of Arts

Abstract

The objective of this study was to evaluate occupational risk factors in the Engraving, Sculpture, and Ceramics workshops of the Faculty of Arts at the Central University of Ecuador, considering current occupational health and safety regulations. Methodologies from the National Institute for Occupational Safety and Health (INSHT) were applied to measure noise and lighting levels, along with the IPMAQ methodology to assess the hazard level in the handling of chemical agents. The results showed that the Engraving Workshop presents a very high chemical hazard index (Q4), due to the handling of substances such as metallic oxides, solvents, and pigments without adequate ventilation or systematic use of personal protective equipment. This environment represents a critical health risk for students and staff, requiring immediate intervention. Regarding noise, the sculpture workshops in metal, wood, marble, and stone showed a medium risk level, caused by the continuous use of electric tools and heavy machinery. Although the maximum permissible levels were not exceeded, prolonged exposure may lead to adverse effects such as hearing loss or occupational stress. In terms of lighting, all evaluated workshops exhibited significantly lower levels than those required by Ecuadorian regulations, qualifying as high risk. This deficiency increases the likelihood of errors, visual fatigue, and accidents during the use of tools. It is concluded that it is essential to redesign ventilation and lighting systems, provide continuous training to workshop users, and promote an active culture of prevention. The joint participation of academic authorities, faculty, and students is key to ensuring safe and healthy environments, in alignment with the principles of educational quality and occupational well-being.
