Abstract
An on site visit was made to Tri-Air Incorporated (SIC-2869), Firebaugh, California to gather data on hazardous working conditions for persons involved in the application of paraquat (1910425) for cotton defoliation and harvest on the west coast. The company employed 22 persons, including six pilots and 12 ground crew. Flagmen, pilots and individuals responsible for mixing the herbicide were monitored for the duration of the paraquat spraying tasks during typical spray application operations. During the spring and summer months, employees worked from 8am to 8pm. In the fall and winter they worked from 6am to 6pm. In many instances another herbicide such as Folax (150505) was used during the first spraying for cotton defoliation. One flagman stood at each end of the designated field with a flag or flashlight to signal the area to be sprayed. As the plane approached the end of the field, the flagger moved to the next area. The chemical handlers wore protective clothing. Eight personal breathing zone and four area samples were taken for paraquat during the 2 day survey. No paraquat was detected in any of the air sample filters.
