Abstract
The use of 80/20 compounds as liquid fumigant mixtures in the grain handling industry was considered. Worker exposures to carbon- tetrachloride (56235) and carbon-disulfide (75150) were measured at representative facilities throughout the industry. Work practices that may contribute to high exposure levels were cited. The use of fumigants on stored grain usually occurs when it is found to be infested and is about to be moved through the grain handling system. It is difficult to schedule field visits to coincide with spraying, as there is no set schedule for spraying or other treatment to be given. Approximately equal amounts of liquid fumigants and solid formulations of phosphine (7803512) are used throughout the industry. There is apparently a move toward use of the solid rather than the liquid fumigants for future work. While more grain is stored in the northern states, more use of fumigants occurs in the southern states due to the climate. As spraying is done on a sporadic basis, it does not appear likely to present a major problem such as might be encountered in continuous exposure situations. The authors conclude that grain workers do not appear to be an ideal study group for a neurotoxicity morbidity study due to the fact that the physical distance between study sites and the small number of workers at each site makes it difficult logistically. A concerted effort throughout the grain industry to educate those workers in the grain handling portions of that industry toward the safe handling of fumigants should go far in alleviating any problems arising from exposure to fumigants.
