Abstract
In response to a request concerning excessive noise exposures and subsequent hearing losses, noise exposures were evaluated at the Andrew Breidenbach Environmental Protection Agency Laboratory (SIC- 9511), Cincinnati, Ohio. Particular attention was paid to workers exposed to very high frequency noises being emitted by the turbomolecular pumps of the gas chromatographs. A walk through survey and octave band noise analyses were conducted in ten different laboratories. Sound level readings were obtained from the following types of equipment: gas chromatographs and supporting equipment; plasma atomcomp and supporting equipment; turbomolecular pumps; a glass ampoule sorting, filling, and sealing machine; a Millipore water filtration system; ventilation systems; vapor containment hoods; and a modified cement mixer. In nine of ten laboratories, the overall noise levels were below the current OSHA permissible levels of 90 decibels-A (dB-A) and below the NIOSH levels of 85dB-A. In the laboratory with the glass ampoule machine, levels of 87dB-A were obtained while the machine was in operation. Little systematic hearing loss over the years of employment was determined in 25 employees. Hearing test results for three employees were being studied in more detail. The authors conclude that no health hazard exists at this facility due to noise exposure. Recommendations were made to continue additional soundproofing steps and to encourage wearing of hearing protective devices in noisy areas of the laboratory.
