Clasificación de reactivos químicos en los laboratorios de la Universidad Nacional

During 2008-2010 inventories of chemical reagents used and stored in teaching and research laboratories of Omar Dengo and Benjamin Nunez campuses of National University were generated. E ach laboratory coordinator was asked to fill out a form that included name, quantity and CAS number of every chemical reagent stored and utilized in the laboratories. Chemical reagents were then classified according to the risk categories described by the United Nations IMDG Code. Such a classification process allowed the development of distribution patterns of the chemical reagents within the schools, institutes and research centers of Universidad Nacional. In addition, they were identified the chemicals hazardous classes of the reagents of larger and lesser utilization within the university laboratories. An adequate chemical reagent management, along with a classification system based upon risk categories, is necessary in order to establish a safe working environment in university laboratories. Classification of chemical reagents permits reduction of the administrative, economical, legal, safety, and technical expenses associated with chemical emergencies management; furthermore, it allows the development and application of preventive work practices by students and university personnel during chemical reagent manipulation.
