Implementación de medidas en prevención y control del riesgo estrés térmico en la Planta de Utilidades de la Refinería de Esmeraldas

Abstract

The aim of the work was to identify, evaluate, propose, implement and verify measures to prevent and control risk factors of thermal stress on the ground Utilities of Esmeraldas Refinery. The tool used for identification was the risk matrix of the Ministry of Labor and Employment of Ecuador. In the evaluation by measuring WBGT index, it was established that the area of steam for turbines and equipment in the utility's plant and the addition of chemical areas WBGT average of 38.88 ° C, and sweeping purge burners 35, 88 turbos and maintenance 41.88 ° C, exceeds the vapor limit of WBGT (Wet Bulb Globes Temperatures), ACGIH (American Conference of Governmental Industrial Hygienists), which is 33 ° C. By applying engineering corrective action at source, transmission medium and receiver in Plant Utilities, controlled acclimatization, hydration in the house of rest and in the field, establishing a work-rest regime, a thermal equilibrium was achieved in the workers and also to prevent occupational diseases and deaths.
