The present investigation carried out a study on exposure to noise doses to workers in a company that manufactures, and markets hydrolytic glass containers type 1. The objective is to characterize the exposure profiles of the GES by comparing the results with the LMP. The study population is made up of all workers exposed to noise and the population of 103 and a sample of 45, the methodology used is that of the worst condition and according to the AIHA guidelines. The results were analyzed according to two indicators, maximum value for samples smaller than 6 and in case of higher evaluations it was analyzed under the UCL, obtaining as results 9 groups of GES, of which 89% present a level of exposure without hearing protection greater than the LMP.

The case study describes an industrial hygiene investigation initiated in response to a drilling rig down due to complaints of loud noise, workers decide to shut down one of three drilling rigs (P3: Drill 3) due to loud noise. It begins with the requirement of situational investigation of exposure to noise of the drilling workers in order to identify and evaluate the exposure to noise, for this the industrial hygienist performs a series of noise dosimetry detection, which aims to declare the results as acceptable or unacceptable based on current regulations, identify the characteristics of the noise sources under study and propose control measures in accordance with the fundamentals, communicate the fundamentals and controls to the workers and management. The study population is made up of drilling rig operators exposed to noise, population is 10 and the sample is 11, the methodology use...

Esta tesis se desarrolló teniendo como objetivo determinar la inoperatividad de una perforadora por emisión de ruido en una empresa minera, evaluando el nivel de exposición al ruido de los trabajadores, para ello se planteó el concepto de Grupo de Exposición Similar y análisis de varianza y desviación geométrica estándar. Se realizó el procedimiento para identificación y establecimiento del Grupo de Exposición Similar (GES), un muestreo de 11 evaluaciones para una un GES que tiene una población igual a 10, tal como lo recomienda la metodología NIOSH 77-173, para tener un 95% de Nivel de confianza. El tiempo mínimo de medición 70% de la jornada laboral. Los hallazgos del estudio han permitido establecer que es factible determinar la operatividad o inoperatividad de un equipo mediante la metodología propuesta. Además, se ha determinado que los niveles sonoros del equipo d...
