Resumen
El objeto de la presente tesis es llegar a determinar las mejores condiciones laborales de cuatro puestos de trabajo en la empresa Cora refrigeración que están expuestos a factores de riesgos ergonómicos y Físicos encontrados en la evaluación inicial de riesgos hecha por dicha empresa. Los métodos utilizados para medir dichos factores de riesgos antes mencionados fueron el método para estrés por calor Wbgt y el método Owas para posturas forzadas. Los resultados encontrados en las mediciones de estrés por Calor indicaron que los cuatro puestos evaluados, Jefe Técnico, técnico Mecánico, Eléctrico y Refrigeración no poseen riesgos y pueden laborar un promedio de 8 horas diarias continuas. En lo que respecta a los riesgos ergonómico el puestos de Jefe técnico tiene un 44% de posturas no adecuadas , el de técnico en refrigeración un 35% , el de técnico eléctrico 44% y el de técnico mecánico un 53% se debe dar una mayor capacitación de posturas laborales, implementar pausas activas en jornada laboral y la supervisión de un médico ocupacional.
The purpose of this thesis is to determine the best working conditions of four job positions Cora Refrigeración which are exposed to ergonomic factors and Physical hazards found in the initial risk assessment made by said company. The methods used to measure the previously mentioned risk factors were the WBGT method for heat stress and de OWAS method for forced postures. The results in Heat stress measurements indicated that the four job positions evaluated (Head Technician, Mechanical Technician, Electrical Technician and Refrigeration Technician) do not present any risks and are able to work an average of 8 continuous hours per day. In regards to ergonomic hazards as head Technician there was a 44% of unsuitable postures, as refrigeration Technician, 35%, a el Electrical technician, 44%; and as mechanical technician 53%. It is necessary to provide more training active breaks during working hours and to be supervised by an occupational health doctor.
