HHE Report, No. HETA-82-186-1203, Perry Nuclear Plant, Perry, Ohio.
A survey was requested by the United Brotherhood of Carpenters and Joiners of America and was performed on March 25, 1982 at Perry Nuclear Power facility (SIC-1629), Perry, Ohio. Employees numbered 300. Personal and area air samples were analyzed for zinc (7440666), iron-oxide (1332372), lead (7439921), nickel (7440020), chromium (7440473), xylene (1330207), methyl-isobutyl-ketone (108101), cellosolve (110805), ethanol (64175), and isopropanol (67630). An earlier study by Environmental Research Group (ERG) was evaluated. Iron-oxide concentrations were 5400 to 9900 micrograms per cubic meter (microg/m3), (evaluation criterion: 5000microg/m3), nickel from 720 to 850microg/m3: (15microg/m3) and chromium from 650 to 1100microg/m3: (25microg/m3). Chromium concentrations taken by ERG were 1 to 270microg/m3. ERG found four samples exceeded the evaluation criterion for zinc (criterion: 5000microg/m3); five for lead (500microg/m3) and seven for chromium (microg/m3). The combined exposures to organic compounds during C-191 painting were 88 and 93 percent of the evaluation criteria for two samples. ERG found silica (14808607) exceeded the evaluation criteria of 50 micrograms per cubic meter. The author concludes that workers may have been overexposed to iron-oxide, zinc, lead, nickel, silica, and chromium. Exposures were generally below OSHA standards, but above NIOSH standards. Exposure controls are recommended.
