HHE determination report no. HHE-76-74-393, Great Lakes Research Corporation, Elizabethton, Tennessee.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 76-74-393, 1977 May; :1-6
A Health Hazard Evaluation investigation was conducted by NIOSH at the Pilot Plant of Great Lakes Research Corporation in Elizabethton, Tennessee, which converts Orlon into carbon and graphite fibers, on June 24, 1976. An authorized employee representative requested the investigation regarding exposure of employees to Orlon carbonization by-products which might have caused discoloration of some workers' hair. Laboratory analyses failed to identify the presence of any unexpected contaminant or substances to cause alteration of hair color among Orlon by-products, settled dusts, process residues, and human hair samples and although there was a positive indication of the presence of an oxidizing agent in the bulk carbon dust sample, a positive identification of the particular oxidizing material was not possible. While the study was not successful in determining the cause of the hair discoloration, it is recommended that all process emissions be captured at their source and removed from the process areas through the use of local exhaust ventilation.
