In addition, NIOSH was asked to evaluate employee exposures to oil mist generated during the processing of the steel. On September 15-17, 1982, NIOSH investigators conducted an initial medical survey at the plant. A follow-up environmental survey was performed on December 1-2, 1982. On the basis of the data obtained during this investigation, NIOSH has determined that a potential health hazard existed at the Empire-Detroit plant due to excessive hexavalent chromium levels. Eyes and upper respiratory system irritation is suggested by a high prevalence of such symptoms reported by employees in dustier work areas. Measures to reduce exposures and improve workers' safety and health are recommended in Section VIII of this report. 收起
