Worker exposures to S,S,S-tributylphosphorotrithioate (78488) (DEF) were determined at B and B Hogue Harvestor (SIC-0722) in Mendota, California, on November 13 to 15, 1978. The survey was part of a NIOSH study of the health effects of occupational DEF exposure. Approximately 15 workers were assigned to the cotton picking operations that were surveyed. The company had no formal industrial hygiene program. A safety program was staffed by 16 persons. Medical services were provided by local physicians. Personnel records provided demographic information, department assignments, and absence reports. Air samples for DEF ranged from 8.5 to 67.5 nanograms per cubic meter. Two skin exposure samples were 0.13 and occupational DEF exposure at the time of the survey. The author concludes that based on available toxicological data, no adverse health effects were likely to result from the exposures noted during this survey.
