Abstract
Bulk and air samples were analyzed for carbon-tetrachloride (56235), chloroform (67663), ethylene-dichloride (107062), 1,2- dichloroethylene (540590), carbon-disulfide (75150), methyl-bromide (74839), methylene-chloride (75092), and ethylene-dibromide (106934) in a grain shipment (SIC-5153) in Superior, Wisconsin in February, 1984. The grain was aboard railcars located in a railroad yard waiting to be unloaded. The evaluation was requested by a union local and the district's Congressman due to concern that the grain had been heavily treated with chemical fumigants. Seven of 26 cars in the train were sampled. No workers were evaluated. All bulk samples contained carbon-tetrachloride and carbon-disulfide in concentrations of 0.75 to 61 and nondetectable to 6.5 parts per million (ppm), respectively. Traces of chloroform and methylene- chloride were found. Carbon-tetrachloride, at a maximum concentration of 0.46ppm, was the only halogenated compound found in the air samples. The author notes that the measured concentrations should not be interpreted as worker exposures as the samples were collected for identification purposes only and were taken at locations considered unrealistic for a worker's breathing zone. Recommendations include requiring workers opening fumigated railcars to wear self contained breathing apparatus and implementing a method of tracking grain fumigation during passage through the grain handling system.
