Health Hazard Evaluation Determination Report No. 76-33-431, 76-34-431, Kaiser Aluminum and Chemical Corporation, Ravenswood, West Virginia

摘要

A Health Hazard Evaluation investigation was conducted by NIOSH on July 27-29, 1977, at the Kaiser Aluminum and Chemical Corporation, Ravenswood, West Virginia in the facility for the production of virgin aluminum metal by electrolytic reduction of alumina (1344281) using prebaked carbon electrodes and cryolite (1344758) flux. Environmental sampling revealed that the anode setters in the pot area may be exposed to excessive concentrations of aluminum oxide (1344281), while fluoride exposure was not excessive. In the casting area exposure to carbon monoxide (630080), sulfur dioxide (7446095) and ammonia (7664417) was minimal. According to available medical data, the findings related to determining whether a high rate of coronary disease existed were inconclusive. Recommendations are made for environmental control and medical surveillance of employees.
