NIOSH 1993 Jul:13 pages
In response to a request from the Safety Coordinator of Silver Mountain Enterprises (SIC-2499), an investigation was begun into possible wood dust and noise exposures at their manufacturing facility in Montrose, Colorado. Handicapped individuals were employed at the woodshop manufacturing wood surveyor's stakes. Short term wood dust exposures ranged from 0.2 to 4.1mg/m3. The calculated time weighted average exposures were all below the OSHA and NIOSH exposure limits. The highest exposures from normal operations were seen from workers on the two table saws. The highest consistent task samples were found during clean up operations. Workers used brooms to dry sweep the floors and brush off machine surfaces. Personal noise dosimetry equipment indicated that average exposures over several time periods ranged from 79.8 to 93 decibels-A. The table saw operators had the highest general exposures, with equivalent exposures in the 85 to 93 decibel-A range. A partial hearing conservation program was in effect. The author concludes that a potential health hazard existed from overexposure to noise. The author recommends that a complete hearing conservation program be established.
