Personal and area air samples were analyzed for total dust, organic solvent vapors, and metals during spray, brush, and roller painting and paint removal operations (SIC-1629) at Millstone Nuclear Power Station Number 3 construction site, Waterford, Connecticut, March 1981. Solvent exposures were generally well below their relevant standards. Total dust exposures during paint removal ranged up to 1,000 milligrams per cubic meter (mg/m3) in the containment building. The OSHA standard for total dust is 15mg/m3. Exposures to lead (7439921) dusts exceeded the OSHA standard of 0.05mg/m3 in the turbine, auxiliary, and containment buildings. Chromium (7440473) exposures were generally below the OSHA standard of 1mg/m3, except for 2.4mg/m3 in a personal sample taken during paint removal in the containment building. Very few engineering controls other than 3M single use respirators were observed. The authors note that the chromium exposure data is difficult to interpret as the form of the chromium is not known. If the chromium existed as hexavalent chromium, exposure was excessive. The authors conclude that in view of the measured exposures to total dust, lead, and chromium, engineering controls and respiratory protection are inadequate. Recommendations include implementing better controls and respiratory protection.
