Preliminary Control Technology Assessment of Didier Taylor Refractories Corporation, South Port, Kentucky, Report No. CT-110-13A.
An on site visit was made to the Didier Taylor Refractory Corporation, South Port, Kentucky to evaluate the control systems at this facility which limit the exposure of workers to silica (14808607), noise, and heat. Various raw materials were mixed, dried, crushed, ground, and pressed or molded into shapes before firing in the kiln at this facility. The facility produced over 5,000 speciality type nonclay refractory products. Raw materials used include aluminum compounds, bauxite (1318167) or alumina (1344281), Mullite, chromium (7440473), titanium (7440326), zircon, magnesia, phosphate, and kaolin. A pneumatic system was used to unload bulk powdered raw material. Local exhaust ventilation was used in the bag emptying area and other areas where powders were exposed. General exhaust ventilation was used in most of the buildings. Personal protective equipment included hard hats, safety glasses without side shields, a variety of hearing protectors, safety toe shoes, respirators, gloves, and heat protective clothing. The author concludes that there are a number of operations at this facility which have a potential for causing high worker exposure to chromium metal, heat, noise, and nuisance dust. The author recommends that this refractory facility be included in an in depth survey.
