Results and conclusions of initial and followup evaluations conducted on one of three cotton gins on the Colorado River Indian Reservation in Poston, Arizona were presented. Cotton dust levels at the Plantation Gin exceeded NIOSH and OSHA recommended levels in all but one sample. Pesticide residues were identified in samples of first picked cotton, cotton bolls, trash cotton, seeds, motes, waste/bract cotton, finished cotton, and rafter samples. Levels of nuisance dust ranged from 0.25 to 1.6mg/m3. Noise measurements ranged from 78 to 101 decibels-A in different locations in the gin. The equipment appeared to be in good condition and housekeeping was considered fair. Low cholinesterase levels were seen in one worker and significant decreases in lung function over a work shift were observed in two workers. Nine of 15 workers reported symptoms such as eye or nose irritation or chest symptoms. Recommendations on improved housekeeping and the use of personal protective devices for respiratory and ear protection were made.
