HHE determination report no. HHE-74-25-267, Kaiser Aluminum and Chemical Corporation, Ravenswood, West Virginia.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 74-25-267, 1976 Mar; :1-26
Environmental sampling was conducted and medical examinations administered to workers at the Kaiser Aluminum and Chemical Corporation (SIC-3334) in Ravenswood, West Virginia on July 8-11, 1974, and August 26, 1974 to determine employee exposure to toxic concentrations of dust, particulate polycyclic organic matter (PPOM), and benzo(a)pyrene (50328) (BaP). An evaluation request came from an authorized representative of approximately 150 affected employees. All samples were below federally acceptable levels of 2.4 milligram per cubic meter (mg/m3) for coal dusts, 2.5 mg/m3 for fluorides, 5 mg/m3 for manganese (7439965), and 0.2 mg/m3 for PPOM. Samples of PPOM showed BaP content to be below minimum detectable concentrations. None of the workers showed evidence of carbon pneumoconiosis. The authors recommend using NIOSH approved respirators, making respiratory air quality checks, establishing a respiratory maintenance program, controlling contaminants at the source, using vacuum or wet methods for cleaning operations, starting maintenance programs for all machinery, routine wetting of yard area, dampening of spills or accumulations of pitch to minimize dust generation, using protective clothing for employees, and using safety glasses. The authors further recommend that possible worker exposure to asbestos be assessed.
