NIOSH 1986 Dec:39 pages
A sugar beet mill (SIC-2063) owned by the American Crystal Sugar Company (ACSCO) was evaluated for worker exposure to airborne contaminants during beet processing and welding fumes during facility maintenance, following a request from ACSCO management and the American Federation of Grain Millers International Union. Beet processing involved approximately 690 workers, while maintenance involved approximately 300 of these workers. Total and respirable dusts were measured in personal and general air samples, and personal welding filter samples were analyzed. Analytical methods included spectroscopy, X-ray diffraction, gravimetry, and chromatography. Quartz (14808607) was detected in settled dust and high volume air samples; beet pulp was considered to be a potential health risk. Exposures in excess of the most stringent environmental criteria were found for calcium-oxide (1305788) in lime kiln workers, formaldehyde (50000) in diffuser area workers, and total welding fumes, nickel (7440020), and iron-oxide (1332372) during welding operations. Exposures to nickel and formaldehyde presented potential cancer risks. Interference prevented analysis of hexavalent chromium (18540299), but the authors expect that it would be elevated. The authors recommend formaldehyde replacement, particulate containment, ventilation improvement, and use of appropriate respiratory protection.
