Abstract
In response to a management request, worker exposures were evaluated at the General Casting Company (SIC-3321) Curtis Street Facility, Delaware, Ohio. The facility was a casting cleaning facility for gray and ductile iron foundries. Two shifts operated at the facility with a total of 52 employees. Personal breathing zone air concentrations of respirable silica (14808607) ranged from 163 to 19,870 micrograms per cubic meter (microg/m3). All the 24 samples taken exceeded the NIOSH Recommended Exposure Limit (REL) of 50microg/m3. Twenty one samples contained cristobalite (14464461). Of the 16 iron exposures measured for the chipper/grinders, 12 exceeded the REL of 5,000microg/m3. Several nickel (7440020) concentrations exceeded the REL of 15microg/m3. Grinders were overexposed to noise. A paint dip tank area sample exceeded the 100 parts per million OSHA standard for xylene (1330207). Exposures to benzene (71432), ethyl-benzene (100414), toluene (108883) aluminum (7429905), chromium (7440473), copper (7440508), lead (7439921), magnesium (7439954), manganese (7439965) and zinc (7440666) did not exceed recommended limits. The authors conclude that workers were overexposed to respirable silica, cristobalite, iron, nickel, and noise; there was a potential health hazard from xylene. The authors recommend that engineering controls, use of personal protective equipment, and work practices be improved.
