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

Abstract

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.

  • Following a request from the American Federation of Grain Millers International Union and management of the American Crystal Sugar Company (ACSCO), employee exposures to airborne contaminants during beet processing and welding fumes during facility maintenance were determined at a sugar beet mill owned by ACSCO. Exposures in excess of the most stringent criteria were found for calcium oxide and calcium carbonate in lime kiln workers, sugar dust in sugar bin workers, insoluble hexavalent chromium and nickel during welding, total welding fumes in one case, and nickel during a metal coating spray process. Quartz was found in several settled dust samplesmore » and high volume air samples. Nickel and chromium exposure presented potential cancer risks. The authors conclude that workers were overexposed to calcium oxide, calcium carbonate, sugar dust, total welding fumes, hexavalent chromium, and nickel at this facility. Recommendations include particulate containment, ventilation, and respiratory protection where appropriate.« less
  • A sugar-beet mill 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. 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 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 environmentalmore » criteria were found for calcium-oxide in lime kiln workers, formaldehyde in diffuser area workers, and total welding fumes, nickel, and iron-oxide during welding operations. Exposures to nickel and formaldehyde presented potential cancer risks. The authors recommend formaldehyde replacement, particulate containment, ventilation improvement, and use of appropriate respiratory protection.« less
  • 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 owned by ACSCO. Exposures exceeding the most stringent environmental criteria were found for calcium carbonate and carbon monoxide 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, nickel, iron-oxide,more » and calcium-oxide. 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.« less

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, coal dust, crystalline silica, sugar dust, and formaldehyde. Areas of greatestmore » exposure included lime-kiln operation, coal handling, and storage-bin housekeeping.

  • A reevaluation of the air quality in the Marietta Tower Building, Atlanta, Georgia was requested by the DHHS Region IV Employee Health and Safety Committee because of worker complaints about sinus problems, eye irritation, and headaches. Air cooling and circulation units were inspected on six floors. Outside air supply to these floors was measured and the buildup of carbon dioxide determined as an indicator of indoor pollution.
