Health Hazard Evaluation Determination Report HHE 80-247-1210, Supplement, Colorado River Indian Reservation, Cotton Gin Study, Parker Valley Gin, Parker, Arizona

摘要

Results and conclusions of initial and follow-up evaluations conducted on one of three cotton gins on the Colorado River Indian Reservation in Parker, Arizona, were presented. Cotton dust levels at the Parker Valley 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 2.0 to 10.5 mg/cubic m. Noise measurements ranged from 84.5 to 98 decibels-A in the gin. The equipment appeared to be new and in excellent condition and the housekeeping was considered to be good. Recommendations on maintaining the level of housekeeping and the use of personal protective devices for respiratory and ear protection were made.
