Identificación, clasificación y control de las principales sustancias químicas que se manejan en los laboratorios del Colegio Montessori British School a través del sistema globalmente armonizado

Abstract

Through the globally harmonized system, used as a chemical risk management mechanism, it is possible to communicate the different physical, health and environmental hazards in a harmonized and understandable way. Using tools such as labels and data sheets, it is possible to improve chemical safety in sectors such as education, where the main population exposed are teachers and students. For this reason, this work performed the hazard identification of 102 reagents stored in the laboratories of the Montessori British School, and in turn was able to comply with one of the guidelines of the Ministry of National Education, which is based on reducing the risk of accidents and diseases due to ignorance, bad and / or inappropriate conditions. Through the globally harmonized system, used as a chemical risk management mechanism, it is possible to communicate the different physical, health and environmental hazards in a harmonized and understandable way. Using tools such as labels and data sheets, it is possible to improve chemical safety in sectors such as education, where the The main exposed population are teachers and students. For this reason, this work carried out the identification of dangers of 102 reagents stored in the laboratories of the Montessori British School, and in turn was able to comply with one of the guidelines of the Ministry of National Education, which is based on reducing the risk of accidents and diseases due to ignorance, bad and / or inadequate conditions. As a control mechanism for the prioritized substances, hazard communication labels and an instruction manual were elaborated, in which the activities to carry out the classification and labeling of chemical products according to the GHS are defined. Finally, it was identified that 98% of the total of the identified substances presented more than one hazard class among categories 1, 2, 3 and 4, of which at least 78% presented health hazards, mainly with hazard categories 1 and 2 in relation to specific toxicity of target organs, single and repeated exposure, respiratory or skin sensitivity, mutagenicity in germ cells, aspiration and reproductive toxicity, formaldehyde being the most dangerous substance because it presents 4 classes of health hazards with category 1 y2.
