Health hazard evaluation determination report HE-80-71-703, Bear Creek Uranium Company, Douglas, Wyoming

Technical Report ·
OSTI ID:6408181

An environmental survey was conducted in February 1980 to evaluate exposure to CRC, a cleaning solvent containing perchloroethylene (127184), (PCE) and 1,1,1-trichloroethane (71556) (TCE) at Bear Creek Uranium Company (SIC-1094) in Wyoming. The survey was requested by the company safety engineer. Breathing zone and general room air samples were collected and analyzed. One mine electrician was exposed to 6,500 milligrams per cubic meter (mg/cu m) (PCE recommended OSHA limit is 690mg/cu m). Of the 7 samples of TCE, none exceeded the OSHA standard of 1900mg/cu m. Overexposure did occur when workers used the solvent in confined areas. The authors concluded that a health hazard existed when the solvent was used on confined spaces, and they recommend improved work practices.
