Description:Environmental and personal air samples were analyzed for the presence of toluene (108883), mineral-spirits (8030306), naptha (8030306), methyl-isobutyl-ketone (108101), total particulates, respirable particulates, respirable free silica (7631869), iron- oxide-fume, chromium (7440473), nickel (7440020), copper (7440508), and aluminum (7429905), at the American Concrete Division of the Union Metal Company (SIC-2819) in Waukegan, Illinois on March 30, July 5, and October 20, 1978. An evaluation request came from an authorized representative of the approximately 60 affected workers. The airborne concentrations of respirable free silica in three personal samples exceeded the NIOSH recommended standard of 0.05 milligrams per cubic meter (mg/CuM), and ranged from 0.013 to evaluation criteria. The author recommends reducing crystalline silica by using engineering controls, institution of a respiratory protection program, enclosure of the mold spinning machines, and the control of peak exposures to air contaminants by the installation of local ventilation systems on respiratory protection equipment.
