Preliminary control technology assessment of Crane Company, Ferguson, Kentucky.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, ECTB 110-20a, 1983 May; :1-3
Health hazard control methods, work processes, and existing control technologies were evaluated at Crane Company (SIC-3261), Ferguson, Kentucky in September, 1982. The company employed 250 workers for production of vitreous china plumbing fixtures from ball clays, flint, and feldspar. Materials were received already ground to production specifications, and were mixed with water in an underground rotary mixer to produce slip. The blended slip was pumped to vibrating shaker screens where it was classified and transported to slip storage wells. The slip was pumped to air pressurized holding tanks, then to the casting bench where it was poured into plaster molds and allowed to harden. After finishing, the cast was dried for 24 hours at 160 to 180 degrees-F, and glazed. The glazed cast was fired for 24 hours at 2300 degrees, then cooled, packed and shipped. A program of monthly inspections and safety meetings existed, and environmental monitoring was also performed. Workers were provided with dust masks, safety glasses, and hearing protectors. Local exhaust ventilation was used at the glaze spraying and grinding operations. The author does not recommend an in depth study of this company since there is no clay preparation operation and no unique control technologies are used.
