Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, HETA 94-0191-2670, 1997 Dec; :1-24
On March 11, 1994, the National Institute for Occupational Safety and Health (NIOSH) received a request for technical assistance from the Minnesota Department of Labor and Industry, Occupational Safety and Health Division (Minnesota OSHA), in evaluating potential health hazards at the Bureau of Engraving, Incorporated, (BOE) in Minneapolis, Minnesota. A second request for a health hazard evaluation (HHE) at BOE was received by NIOSH on March 28, 1994, from the Graphic Communications International Union (GCIU) Local 1B. Both request concerned employee exposure to chemicals used in the clean room, including solvents and glycol ethers used with the Ciba Geigy (trademark) coating process. Symptoms reported among clean room employees included difficulty breathing, headaches, skin and eye irritation, and dizziness. Site visits were conducted in May 1994 and April 1995. Personal breathing zone (PBZ), area, and process air samples were collected for hexane and other hydrocarbons, alcohols, and glycol ethers. Analysis of full-shift PBZ air samples revealed detectable levels of hexane, 1,1,1-trichloroethane, and propylene glycol monomethyl ether acetate (PGMEA), but all concentrations were well below the corresponding occupational exposure criteria. Propylene glycol monomethyl ether (PGME) and ethylene glycol monobutyl ether (EGBE) were not detected.
