All samples were either below laboratory detection limits or well within the evaluation criteria established for this report. None of the workers were receiving any exposure. Noise measurements were taken on twelve workers in the Clean Room. Their exposures averaged less than 80 dBA. At no time during the work cycle was the evaluation criterion of 85 dBA exceeded. None of the workers had work associated health complaints. NIOSH investigators concluded that a health hazard did not exist at the time of this survey. 收起
