Influência do ruído em uma usina de processamento de resíduos sólidos urbanos baseada nas normas NR-15 (2011) MTE e NHO 01 (Fundacentro)

Abstract

This study aimed to evaluate the noise exposure of environmental agents working along the treadmill separation of solid waste in the Processing Plant Solid Waste Jaguariaíva/PR, using the procedures described in NHO 01 (2001 ) and NR15 ( 2011). Using a dosimeter, the measurement was performed in the sound pressure level to which workers are exposed. Thus, two workers who remain with the noise source throughout the workday were chosen. While one of them, the calibrated dosimeter was used as established by NHO 01, on the other, the procedure was the same but was calibrated according to NR-15. After the data analysis, it was found that workers who perform activities along the conveyor for sorting solid waste are not exposed to dangerous levels of sound pressure, though, has been ascertained that in both normalizations employed, preventive measures should be implemented.
