Estudio del ruido laboral y vibraciones en el proceso de acabado de la empresa La Fortaleza Cia Ltda. de la ciudad de Ambato

Abstract

For this project, the used PCE 322A sonometer, where measurement strategy justified is according the provisions of the technical note noise prevention NTP270, the end of evaluation was determined the existence the noise exposure in the company Fortaleza Cia Ltda and work areas with exposure noise are painting and refile and for vibration the used BALMAC 230 vibrometer where measurement strategy justified is according the provisions of the NTP 839 where the objective is the inform the fundamentals and the method for evaluating the risk arising from exposure to vibration. Later is determined the equivalent level daily the worker exposed, for this step was necessary to know the working conditions, this information is important for determine the implanted the sonometer or the dosimeter, because the technical notes NTP noise 950 and 951 establish noise measurement strategies for each of the instruments. As a result of vibration it was determined that the job of polishing the risk value is 2.28 which corresponds to the risk of harmfulness to the hand system - arm and whole body system the risk value is 0.72 which corresponds to risk mean discomfort. And for the job of refile the risk value it is 0.89 which corresponds to an assessment of means discomfort for vibration hand - arm and whole body system the risk value is 0.42 which corresponds to risk with half discomfort.
