Abstract
Personal air samples were analyzed for carbon-disulfide (75150), ethylene-dibromide (106934), carbon-tetrachloride (56235), and grain dust at grain elevators (SIC-5153) located at Superior, Wisconsin and Duluth, Minnesota in May, 1984. The survey was requested by a representative of Local 118 of the American Federation of Grain Millers to evaluate exposures to grain fumigants and dust among workers at the two sites. All concentrations of carbon-disulfide, carbon-tetrachloride, and ethylene-dibromide were below the detection limit. Grain dust concentrations ranged from 0.34 to 38 milligrams per cubic meter (mg/m3). The American Conference of Governmental Industrial Hygienists threshold limit value for airborne grain dust is 4mg/m3. Short term sampling for the fumigants was performed; however, the results were inconclusive. The author concludes that a health hazard due to overexposure to grain dust exists at the grain elevators. Recommendations include providing workers with respirators equipped with dust cartridges, implementing local exhaust ventilation at rail car dumping and loading points, and instituting a method of tracking fumigated grain shipments through the grain handling system.
