In Olinda there are an estimated 50 marble quarries, 3 of which are members of the stone extraction and finishing industry's state union. The objective here is to quantitatively evaluate the noise present at the workplace in two of Olinda's unionized marble quarries. The data to be analyzed was collected during December 2010, this month representing one of the four busiest months of production. The samples were collected from Tuesdays to Fridays in order to avoid irregular outcomes. Instantaneous readings were taken with the decibel meter to identify points of Noise Pressure Level (NPL) higher than Action Level (AL). Afterwards, the full procedure for the characterization of noise level with the decibel meter in order to compare the Homogeneous Exposure Group (HEG) to those with High Risk Exposure (HRE) was initiated. The noisiest sources came from humid cutting machines, marble saws and polishing equipment. The activities of cutter and polisher became classified as follows: unsafe, in a critical situation and in need of priority control for the work environment with noise level values varying from 95.0 dB(A) to 103.3 dB(A), calling for the use of ear protection during the entire work day. |
