Abstract
In response to a request from management, an evaluation was undertaken of worker exposures in the coremaking, molding, pouring, melting, shakeout, cleaning and sand handling areas of the General Castings Power Street Facility (SIC-3321), Cincinnati, Ohio. The facility was a gray and ductile iron foundry which employed 32 workers. Three coremaking processes were used: hot shell, oil bake, and no bake. Of the 15 environmental samples taken, four exceeded the OSHA 100 micrograms/cubic meter (microg/m3) limit for respirable silica (14808607) as quartz. At the time of the survey, a local exhaust ventilation and bag house system was being installed. Personal breathing zone concentrations of lead (7439921) exceeded the 50microg/m3 permissible exposure level for the furnace operator and two pourers. Benzene (71432) exposures were in excess of the 0.1 part per million recommended exposure limit for two coremakers and a pourer. Carbon-monoxide (630080) levels ranged from 6 to 38 parts per million (ppm). Phenol (108952), toluene (108883), formaldehyde (50000), and other metals did not exceed recommended criteria levels. The authors conclude that workers without respiratory protection were overexposed to respirable silica, lead, carbon-monoxide, and benzene. The authors recommend that engineering controls and improved work practices be instituted to control exposures.
