HHE determination report no. HHE-76-101-376, FMC Corporation, Broomfield, Colorado.
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 76-101-376, 1977 Mar; :1-16
Acting on a request from the management, a Health Hazard Evaluation survey was conducted by NIOSH on August 27 and September 8, 1976 to determine the potential hazards associated with exposure to methanol (67561), ethyl-acetate (141786), isopropyl-alcohol (67630), trichloroethylene, acetone (67641), Freon-11-R, chloroform (67663), hydrochloric-acid (7647010), nitric-acid (7697372), aluminum-oxide (1344281), and hydrofluoric-acid (7664393) during the manufacturing of semiconductors (SIC-3674) at the FMC Corporation facility in Broomfield, Colorado. Breathing zone samples taken from almost all exposed workers revealed that a health hazard existed at the time of the evaluation to both chloroform and Freon-11-R. When approximately 20 "affected" workers were interviewed, one complained about previous exposures to hydrofluoric-acid, resulting in some nerve damage in the fingers, and one claimed minor irritation from exposure to hydrochloric-acid. At the time of the evaluation, two workers were overexposed to Freon-11-R and chloroform, respectively. Recommendations are made for preventing recurrence of the incidents reported, by using respirators, improving local exhaust ventilation, and by stressing better work practices.
