Abstract
A field survey was undertaken of Colorado forest service workers for the purpose of evaluating ethylene-dibromide (106934) (EDB) exposure of these workers involved in fumigating felled pine trees in forest locations near Dillon, Colorado. The Service employed 15 workers to apply EDB in forest locations during the survey period. Two methods of fumigation were used. For smaller piles, the EDB emulsion was carried in 5 gallon jerry cans to the site of a small pile and a calculated volume (2.0 gallons per cord) of emulsion was poured through a slit in the plastic covering onto the stacked wood. When completed, the slit was sealed with adhesive tape. For larger piles of cut trees, insecticide was applied by spraying the emulsion under pressure by hose supplied from a nearby tank truck. The EDB content in the emulsion was about 4% by volume. Considerable potential for exposure to EDB was noted in the insecticide application operations. Exposures exceeded both the recommended ceiling limit of 130 parts per billion (ppb) and the time weighted average NIOSH exposure limit of 45ppb. Work assignments directly affected worker exposure. Pouring the emulsion resulted in less exposure than spraying. The author recommends specific measures to reduce the level of exposure.
