NIOSH 1986 Dec:40 pages
Employee exposures to airborne contaminants during sugar beet processing and to welding fumes during facility maintenance were evaluated at a sugar beet mill (SIC-2063) owned by the American Crystal Sugar Company (ACSCO), in response to a request from the American Federation of Grain Millers International Union and ACSCO's management. Sugar processing operations involved approximately 370 workers, and welding potentially exposed ten to 15 workers. Personal and general air samples were collected and analyzed for several chemicals, total and respirable dusts, and metals and welding fumes. Methods included gravimetric analysis, chromatography, spectroscopy, and X-ray diffraction. Exposures in excess of the most stringent criteria were found for calcium-oxide (1305788), coal dust, crystalline silica (14808607), sugar dust, and formaldehyde (50000). Areas of greatest exposure included lime kiln operation, coal handling, and storage bin housekeeping. The latter was only an area of potential exposure, since workers wore dust respirators. Detectable formaldehyde levels in general air represented a possible carcinogenic risk. Presence of silica in bulk samples presented a potential risk of silicosis. Exposures to total welding fumes and metals exceeded stringent criteria in two thirds of samples. Potential cancer risks included hexavalent chromium (18540299) and nickel (7440020). Recommendations include use of respiratory protection, dust and fume containment, and formaldehyde replacement.
