| dc.description.abstract | The purpose of this study was to evaluate the noise exposure experienced by employees at Company XYZ and the existing hearing protection practices within the Fabrication area during normal operations. Personal dosimetry noise monitoring was previously conducted over 2 consecutive days to assess the noise exposure levels of employees working in the area. The goal was to measure personal noise exposure and identify peak noise levels produced by operating equipment. A previously conducted noise dosimetry study indicated that noise exposures were below the Occupational Safety and Health Administration (OSHA) 8 hr 90 dBA Permissible Exposure Limit (PEL), although one sample likely exceeded the 10 hr, OSHA adjusted 85 dBA action level exposure limits. All employees exposed to noise levels at or exceeding an 8 hr Time-Weighted Average (TWA) of 85 dBA are mandated to participate in annual training regarding the effects of noise on hearing. This training includes the impact of noise, as well as the benefits and drawbacks of various types of hearing protectors. Company XYZ’s hearing conservation program documents training with the need to address the purpose of audiometric testing and outlines the procedures involved during the testing process. Based on the collected data and analysis for this study, it is recommended that Company XYZ assess various engineering modifications not limited to adding soundproof curtains which are aimed at reducing noise and conduct personal and area monitoring, as well as assess the need for the use of double hearing protection in areas where excessive noise levels exist. | en_US |
