In response to a request from the American Federation of Grain Millers, Local 48, a study was made of occupational exposures during corn and corn product processing at the Hubinger Company, Inc., (SIC- 1046), Keokuk, Iowa. This facility was engaged in the wet milling of corn and production of food products such as fructose, corn oil, corn germ and corn starch. Overexposure to epichlorohydrin (106898) was deemed unlikely. However, respiratory protection and protective gloves should be worn when working around this substance. Acid exposures occurred only in refining areas. Sulfuric-acid (7664939) and phosphoric-acid (7664382) exposures were of concern due to the high concentrations used. Sulfur-dioxide (7446095) exceeded the NIOSH evaluation criteria of 1.3mg/m3 in 11 of 13 general room air samples. One worker out of seven monitored for total particulate and free crystalline silica (14808607) was overexposed to quartz. The author concludes that a health hazard existed from exposures to crystalline silica, epichlorohydrin, sulfuric-acid, and sulfur- dioxide. Although five cases of multiple sclerosis were noted among current and former workers, there had been no known occupational etiology for this disease and no known connection between the disease and chemicals or working conditions at this site. The author recommends that engineering controls and respiratory protection should be used to reduce exposures.
