Avaliação dos níveis de ruído e elaboração de APR para um laboratório de testes elétricos

Abstract

Exposure to excessive noise is a cause of several associated pathologies. A healthy work environment necessarily requires the adoption of measures that provide acoustic comfort for the workers who work there. In this context, any substantial change in the lay-out of a work environment, or even the acquisition and installation of new equipment in this environment require that the health and safety at work service of the company, together with the managers of the place to be modified, analyze, measure and, if appropriate, carry out the adaptation of the environment. Institutions such as FUNDACENTRO and the MTPS define in their norms the limits of tolerance to which workers can be subjected. Therefore, since the Normas Regulamentadoras have the force of law, every company that has employees under CLT regime must adapt and comply with these rules. The objective of this work was to analyze a certain environment in which there were substantial changes, and to verify if after such changes, the parameters required by law continued to be fulfilled, specifically in relation to acoustic comfort of the environment. An PHA for the laboratory was also developed. This work was a case study, with a qualitative focus, in which measurements of sound pressure level were carried out in three work stations and analysis of the measurements obtained. The results obtained were satisfactory according to the analyzed NRs, with sound pressure levels within those permitted by law, except for one work station, in which the measurement obtained exceeds the level of comfort indicated by Brazilian legislation, and for which corrective actions are indicated. With this work, it is intended to help in the awareness of workers and managers of the risks associated with excessive exposure to noise.
