Abstract
In response to a request from an employee, a study was made of possible hazardous working conditions at the Barmet Aluminum Corporation (SIC-3341), Livermore, Kentucky. Concern was expressed over exposure to aluminum (7429905) dross dust and ammonia (7664417) vapors in the dross mill, cast house, and furnace building. The raw materials used at the firm consisted of about 80 percent aluminum dross and 20 percent scrap aluminum metal. Analyses were made of a bulk sample of dross, personal breathing zone air, and area air. Ammonia vapors were present in potentially harmful quantities. Airborne concentrations of total dust, respirable dust, and respirable silica (7631869) dust exceeded NIOSH recommended exposure limits or OSHA permissible exposure limits. A self administered questionnaire was used to investigate symptoms in 12 workers from the dross mill and 12 workers from the rolling mill. Respiratory symptoms were not more common among dross mill workers than rolling mill workers. The authors conclude that workers were exposed to potentially hazardous levels of dust and ammonia vapor. The authors recommend specific measures to reduce dust concentration, control employee exposures to metal fumes, control noise exposures, and inform workers of the hazards of their jobs. Good housekeeping and work practices should be encouraged. Open topped spaces such as pits should be treated as confined spaces.
