Evaluación y control de los factores de riesgos físicos, químicos e implementación de señaletica en los laboratorios de calidad de agua e impactos de suelo de la Facultad de Ciencias de la ESPOCH.

Abstract

The evaluation and control of physical and chemical factor risks were carried out in the “Water Quality” and “Soil Impacts” laboratories of Sciences Faculty of the “ESCUELA SUPERIOR POLITECNICA DE CHIMBORAZO” and safety signaling was implemented. The activities developed in the laboratories were identified, and the material process diagrams were elaborated which reflect the transformation, fusion and combination of organic and inorganic raw materials in suitable physical conditions and not suitable for this activity. The methodology NTP 330 was used to evaluated qualitatively the risks found in each procedure and reflected in a technical risk matrix; the level of risk deficiency was performed by means of questionnaires that qualify and provide numerical results; also established exposure, likelihood and consequences; obtaining as results the level of risk and intervention. The processes that had extreme situations were evaluated quantitatively by means of a system of capture of pollutants in the air and quantified the levels of contamination; the exposure limits of the chemical agents were verified in the legal INSHT. As evaluation results, a control was designed in the source of risk, in the environment, and as a last option in the personnel; achieving an optimun working environment in the two laboratories that together with the implementation of the safety signage applied under NTE INEN-ISO 3864-1:2013 are visually prevented risks and dangers. This investigation allowed establishing control parameters to avoid exposure to chemical and physical risks of the personnel, and to prevent occupational diseases in the area. This study recommends the design and implementation of an emergency eye and face system within laboratories.
