Health Hazard Evaluation Report HETA 91-021-2144, Thomson Consumer Electronics,Marion, Indiana

摘要

In response to a request from Thomson Consumer Electronics (SIC-3651), Marion,Indiana, a study was made of possible hazardous noise levels at the site. The facility manufactured and assembled television picture tubes. During the survey periods, both personal noise dosimetry and area noise sampling were completed throughout the facility, specifically targeting areas that had been identified by management as potential high noise exposure areas. Several areas were found where the workers were exposed to noise level in excess of 85 decibels-A (dBA). These areas included the Q-Set/Mask Department, Slurry/Matrix Rooms 1, 2, 5, 6, and 9, Frit Dispense Department, Frit Seal Department, Thump and Flush Department, and the Paint Room next to CIP. In no instance did the values as measured exceed 90dBA. The author concludes that a potential health hazard existed due to noise exposure. The author recommends use of spectral noise data to devise noise reduction controls in the affected departments, and implementing a comprehensive hearing conservation program that should be activated until the noise exposure can be permanently reduced to levels below 85dBA.
