Abstract
The control methods employed at the American Olean Tile Company (SIC- 3253), in Lewisport and Cloverport, Kentucky during the production of quarry clay tile were examined. Potential exposures included silica (14808607), color additives, temperature extremes, and noise. Ball clays and shale were dumped in raw material storage bins. Materials were fed from the hoppers onto conveyors and transported for grinding. The ground material was discharged onto a conveyor for transport to vibrating screens; properly sized particles passed through to another conveyor. Other materials were added from the hoppers onto the conveyor for blending. Blended materials were transported by conveyor to storage hoppers in the mill area. The material was mixed with water, blended, deaerated and extruded in a continuous ribbon which was automatically cut into tiles and placed onto trays in a batch type dryer. Tiles were then fired and finished for shipping. Annual silica sampling was carried out in the crushing area. Annual physical examinations were provided for employees exposed to silica. Protective equipment included respirators, hard hats, dust masks and safety glasses. Local exhaust ventilation systems in the clay preparation and grinding areas were effective in protecting workers. The author recommends that this company be included in an in depth study of ventilation systems to control dusts in clay preparation and grinding areas.
