Abstract
In response to a request from management, an evaluation was undertaken of possible hazardous working conditions as a result of excessive noise at the Neiman Sawmill facilities (SIC-2421), Hulett, Wyoming. The company produced several varieties of untreated boards and lumber products from pine logs. During this survey 108 workers were employed. Noise dosimetry readings revealed that 73% of the surveyed job descriptions (16 of 22) had time weighted average (TWA) noise levels in excess of 90 decibels-A (dBA). Only one job had TWA levels less than the NIOSH recommended limits of 85dBA. Engineering noise controls produced differing amounts of noise reduction to the workers. An enclosure around the planer in the planer mill was found to be effective. However, the separation of the edger and trimmer operations to their own buildings was not an effective noise reduction technique. Hearing tests revealed that 72.5% of the employees exhibited some degree of hearing impairment at one or more audiometric test frequencies. The author concludes that a health hazard existed for workers. The author recommends that a comprehensive hearing conservation program should be implemented. Recommendations for engineering controls for the mills are included.
