Abstract
In response to a confidential employee request, an investigation was begun into possible exposure to contaminants generated during turbine blade and vane manufacture at the General Electric Aircraft Engines (SIC-3724), Madisonville, Kentucky. The company employed about 800 workers in the manufacture of blade and vane components of turbine engines. All solvent concentrations detected during the monitoring period were well below the established limits. With the exception of one sample for nickel (7440020) all personal exposures to metal dust or fume were below the limits. The overexposure to nickel, 20 micrograms per cubic meter (microg/m3), occurred in a 426 minute sample from the Co-Dep operator. The NIOSH Recommended Exposure Limit was 15microg/m3. The highest cobalt (7440484) concentration was 20microg/m3. A cadmium (7440439) concentration of 1.9 microg/m3 was detected at a grinding station. Other substances detected were at levels below the respective allowable limits. Most of the ten employees who reported health problems during medical interviews had upper respiratory irritation and skin rashes. No common cause could be identified. The authors conclude that a potential health hazard from nickel exposure existed at the Co-Dep operation. The authors recommend that smoking be eliminated, housekeeping and ventilation be improved, and alternatives be found to compressed air for cleaning purposes.
