Analíse do ruído ocupacional em uma fábrica de queimadores de fogão na cidade de Caruaru-PE

Abstract

Occupational noise is a feature present in almost all industries, it comes mainly from the machines themselves and the processes within the organization. Noise can be harmful to workers' health and therefore control measures should be taken when it is detected, thus aiming at improving the work environment that directly reflects on workers performance. This work aimed to analyze occupational noise levels in a stove burner factory, assessing the exposure of its employees in certain areas of the company and thus propose mitigating measures to reduce these noises. The work methodology was developed according to the occupational hygiene standard NHO-01, which had the parameters of comparison with the appropriate noise levels for a healthy working environment. The noise level measurements were made with the aid of sound pressure meters, which through thirty measurements in each of the four workstations studied, were calculated the average noise exposed. Through the NR-15 was made the analysis of exposure limiting time values of each post without the use of hearing protection. Thus, it was observed that in some posts the use of PPE is necessary to fulfill an eight-hour workday. Through the noise attenuation calculations, with the use of the suggested hearing protector, it was verified that all the values started to fit the limiting values of the NR-15.
