• Description:
  Health hazard controls used in the ceramics industry (SIC-3259) were surveyed. Work process and control technologies were evaluated at Can Clay Corporation, Cannelton, Indiana in March, 1983. The company employed about 66 workers for production of various ceramic products from Kentucky ball clays. Clay was crushed and transported to a storage bin, then transported to a dry pan grinding unit for fine grinding. Barium-carbonate (513779) was fed into the grinding unit to precipitate naturally occurring salts from the clay. The blended production size material was transported to the production building and then underwent a series of production operations. A potential hazard from silica (7631869) existed because the clays in use were contaminated with about 20 percent quartz. The entire material particle size reduction process was completely automated. The crushing and grinding building was separated from the production building, and two workers were involved in the entire operation. Local exhaust ventilation hoods were provided throughout, and the overhead conveyor was enclosed. Makeup air was provided by overhead fans. The author concludes that these controls are not effective in preventing exposures to potentially harmful particulate concentrations. This company should not be included in an in depth study of control technology effectiveness.
