NIOSH 1986 Dec:48 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 ACSCO's management and the American Federation of Grain Millers International Union. Sugar processing operations involved approximately 375 workers, and maintenance included about 175 of these workers. 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 (9.6 and 11.2mg/m3), Weibul storage bin housekeeper to sugar dust (13.4mg/m3), diffuser operator and charger to formaldehyde (50000) (0.05 to 0.09mg/m3), and welders and cutters to total welding fumes (2.3 to 84mg/m3) and specific metals, particularly hexavalent chromium (18540299) (0.003 to air and settled dust samples contained crystalline silica (14808607), representing a potential hazard. Recommendations include improved particulate containment and ventilation, use of respirators where appropriate, and formaldehyde replacement.
