• Description:
  The effectiveness of health hazard control methods was evaluated at American Olean Tile Company (SIC-3253), Lewisport, Kentucky in November, 1982. This company was selected for study based on results of an earlier survey. The company employed 198 workers to produce non glazed quarry tile from clays containing crystalline silica (14808607). Air movement was measured at various sites, personal air samples were collected for respirable silica and total dust, and area air samples were collected for total dust. Local exhaust ventilation in hand and corner grinding operations effectively controlled dust emissions to between 42 and 51 percent of the permissible exposure limit (PEL) for respirable silica and 57 to 66 percent of the PEL for total particulates. Exposures were also controlled in the automatic grinding area; however, total particulate concentrations were well above the PEL during clay crushing processes. The authors recommend redesign of exhaust hoods in the grinding area; a ventilation technique combined with mechanical brushing for the automatic grinding wheel hold down belts; use of replaceable, lined, and prefabricated sections of duct work; redesign of exhaust duct pick up hoods around blenders and screens; and installation of a clean out/inspection door wherever there are long horizontal duct work runs.
