Title: Health-hazard evaluation report HETA 85-045-1762, American Crystal Sugar Co. , Crookston, Minnesota

Employee exposures to airborne contaminants during sugar-beet processing and to welding fumes during facility maintenance were evaluated at a sugar beet mill owned by the American Crystal Sugar Company (ACSCO), in response to a request from ACSCO's management and the American Federation of Grain Millers International Union. During beet processing, personal breathing-zone and general air samples were collected and analyzed for several chemicals and total and respirable particulates of various dusts. Welding fumes were analyzed by inductively coupled plasma/atomic emission spectroscopy of personal filter samples. The following exposures were considered excessive by the most-stringent criteria: lime-kiln helper to total particulates; Weibul storage-bin housekeeper to sugar dust; diffuser operator and charger to formaldehyde; welders and cutters to total welding fumes and specific metals, particularly hexavalent chromium and nickel. High-volume air and settled-dust samples contained crystalline silica representing a potential hazard. Recommendations include improved particulate containment and ventilation, use of respirators where appropriate, and formaldehyde replacement.
