NIOSH 1986 Dec:38 pages
Following a request from the American Federation of Grain Millers International Union and management of the American Crystal Sugar Company (ACSCO), employee exposures to airborne contaminants during beet processing and welding fumes during facility maintenance were determined at a sugar beet mill (SIC-2063) owned by ACSCO. Beet processing involved 680 workers, and welding exposed a potential ten to 15 workers to metal fumes. Personal and general air samples were analyzed for chemicals and total and respirable dusts, and total welding fumes and metals were analyzed from personal samples. Analytical methods included chromatography, spectroscopy, X-ray diffraction, and gravimetry. Exposures in excess of the most stringent criteria were found for calcium-oxide (1305788) and calcium-carbonate (471341) in lime kiln workers, sugar dust in sugar bin workers, insoluble hexavalent chromium (18540299) and nickel (7440020) during welding, total welding fumes in one case, and nickel during a metal coating spray process. Quartz (14808607) was found in several settled dust samples and high volume air samples. Nickel and chromium exposures presented potential cancer risks. The authors conclude that workers were overexposed to calcium-oxide, calcium-carbonate, sugar dust, total welding fumes, hexavalent chromium and nickel at this facility. Recommendations include particulate containment, ventilation, and respiratory protection where appropriate.
