Abstract
Four taconite plants were studied to establish the extent of hazard to plant personnel that exists based on long-term exposure to noise. The criteria for evaluation include the 90- and 85-dba summations of partial exposures. Data from extensive interviews were used to determine all work stations or locations that employees occupied and how much time they spent in each location in a typical working day. Noise level measurements at every designated location were then made. These time and noise level data were used to find the optimum noise reductions which would be required throughout each plant to meet both noise criteria by a computer program. Subsequently each plant was examined in detail so that the apparent sources of noise for each of the locations requiring noise reduction could be delineated. In tabular form, this report presents the hazardous locations for each plant, the existing noise level, the optimum noise reduction that would be required to meet the current and proposed laws, and the sources of noise that produce the existing noise level.
