NIOSH 1978 May:33 pages
A health hazard evaluation, including mortality and followup environmental studies of worker exposure to oil mist , coal tar- pitch-volatiles (8007452) (CTPV), carbon-monoxide (630080) in the rolling mills of the Alcoa Aluminum Company Warrick Operations (SIC- 3353), Newburgh, Indiana, was conducted. The mortality study was inconclusive, due to the small number of expected deaths, and inaccurate medical histories. It was impossible to determine if Alcoa employees who died from cancer or ischemic heart disease did so as a result of their work exposure. Results of sampling indicate that employees working in the anode block fabrication and kiln area were exposed to hazardous levels of CTPV as cyclohexane (110827) solubles. Fifteen of 17 extracts contained benzo(a)pyrene (505328). Employees were not exposed to hazardous levels of CO and those in the hot mill area and cold mill oil houses were not exposed to oil mist at concentrations which would be expected to result in long term adverse health effects. Recommendations included: pre- employment and periodic physical examinations for carbon plant employees with special attention to oral cavity, skin and respiratory system; environmental monitoring, effective engineering, and administrative controls to reduce exposure to CTPVS to the lowest extent possible; disposable protective clothes for workers exposed to CTPV and prompt decontamination of skin exposed to CTPV.
