Abstract
An in depth industrial hygiene survey was conducted to evaluate worker exposures to phosphine (7803512) during fumigation of grain at the Early and Daniel Co. (SIC-5153) grain elevator in Louisville, Kentucky. Stored grain was fumigated using aluminum-phosphide (20859738). Aluminum-phosphide pellets were also added directly to the grain by the blender as it was poured into the storage containers. Local exhaust ventilation was used at points in the grain moving system where grain dust was generated. Air samples were taken during full shift periods at the breathing zone of the weighmaster, two bin floormen and the blender. Area monitoring samples were also taken. Short term peak period exposures were determined. Phosphine measurements were either below the detectable level or extremely low during this study. Peak exposures to phosphine occurred in the blender and were detectable at 0.2 and 0.6 parts per million during two 1 minute cycles of activity; these exposures were not significant in the blender's overall exposure. If the operators spend considerable time in the vicinity of a bin which is being filled with grain, there is a likelihood of far greater exposure levels being noted. According to the author, further studies of the use of phosphide products at other elevators should be conducted to determine the effect of environmental and process parameters on phosphine exposures.
