Preliminary Control Technology Assessment of Hadley Pottery Company, Louisville, Kentucky, CT-110-19a.
NIOSH 1983 May:4 pages
The general manager of the Hadley Pottery Company (SIC-3262) located in Louisville, Kentucky, requested a walk through survey of his facility to assess potential health hazards from chemical and physical agents to which workers are exposed during the manufacturing of pottery pieces from clays. The company operates on one shift per day and employs 45 individuals in a four story brick building with about 30,000 square feet of space. The native clays are ground to production specifications and brought to the plant, where they are stored in a basement storage area. As needed, the material is blended into a slip mixture in a rotary mixer containing water. The slip is pumped from a storage bin to a filter press where most of the water is removed; the slip cake which remains is cut into slugs. These slugs are formed into the desired greenware, which is dried for 24 hours to allow manual handling. The greenware is then trimmed and wet sponged to the desired finish, after which it is hand painted and sprayed with glaze prior to firing in a kiln. Due to the lack of state of the art controls, it was not recommended that this facility be included in an in depth study. Respirators and a local exhaust ventilation system at the glaze spray booth are used to protect exposed employees.
