In response to a request from management of the American Crystal Sugar Company (ACSCO) and the American Federation of Grain Millers International Union, employee exposures to welding fumes during facility maintenance and to airborne contaminants during beet processing were determined at a sugar beet mill (SIC-2063) owned by ACSCO. Beet processing involved 230 workers, while approximately ten to 15 workers were potentially exposed to welding fumes. General air and personal samples were analyzed for total and respirable dusts and various chemicals, and personal filters were analyzed for welding fumes. Analytical methods included X-ray diffraction, spectroscopy, chromatography, and gravimetry. Quartz (14808607) was found in high volume air samples and settled dust. Exposures exceeding the most stringent environmental criteria were found for calcium-carbonate (471341) and carbon-monoxide (630080) in lime kiln workers and sugar dust in sugar bin workers. Beet pulp dust was considered a potential hazard based on its content of crystalline silica. Welding produced excessive exposures to total welding fumes, hexavalent chromium (18540299), nickel (7440020), iron-oxide (1332372), and calcium-oxide (1305788). Chromium and nickel posed potential cancer risks. The authors conclude that workers were overexposed to calcium-carbonate, carbon-monoxide, sugar dust, total welding fumes, hexavalent chromium, iron-oxide, nickel, and calcium- oxide fumes at this facility. The authors recommend dust containment, ventilation, respiratory protection, and correction of slipping hazards.
