(1982) Supplement, Colorado River Indian Reservation, Cotton Gin Study, Plantation Gin, Poston, Arizona. (Click for full summary) 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/...

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.

The study was conducted on February 4, 1982. The ginning and baling of the cotton normally involves five workers. At the time of the study the gin was not operating, so the description of operations and estimates of expected dust exposures were based on judgment and information provided by the ginner. At the end of the last ginning season, the ginner sent parts of his clothing, his dust mask, and floor dust for analysis. Galecron (6164983), an insecticide, was detected in concentrations of 0.4 to 5.8 parts per million in the apparel and environmental condition was identified as being the direct cause of the health problem. The authors conclude that the ginner has a combination of bronchitis symptoms related to heavy smoking and an atypical byssinosis like syndrome related to cotton dust exposure. Recommendations for a detailed discussion of a follow up survey are provided.

(1982) U. S. Postal Service, Washington Bulk Mail Center, Washington, D.C. (Click to open report) Exposures to asbestos (1332214) and other potential health hazards at the Washington Bulk Mail Center (SIC-4311) in Washington, D.C. were evaluated. The evaluation was requested by the United States Postal Service on behalf of 130 maintenance personnel, and was conducted on August 3 and 4, 1981. Personal air samples for asbestos and respirable particulates were collected and area noise levels were measured. Respirable particulates ranged from 0.03 to standard of 5.0mg/m3.

The evaluation was requested by the United States Postal Service on behalf of 130 maintenance personnel, and was conducted on August 3 and 4, 1981. Personal air samples for asbestos and respirable particulates were collected and area noise levels were measured. Respirable particulates ranged from 0.03 to standard of 5.0mg/m3. Asbestos concentration were below the laboratory limit of detection. Sound pressure levels throughout the facility showed a maximum of 85 to 86 decibels for any one location. OSHA permits a time weighted average (TWA) exposure level 90 decibels while recommending a maximum TWA exposure of 85 decibels. The authors conclude that hazardous exposures to nuisance dusts, asbestos, or noise were not present at the time of the survey. The authors suggest that certain chores should be performed with an industrial type vacuum cleaner equipped with a high efficiency filter system. Workers should be monitored to determine their TWA noise exposures.

Noise levels were also analyzed. The research office requested the study which was performed in March, April, May, and July of 1982. Two employees normally operate the printing equipment. Seven personal and area samples collected in the printing room were assayed for 20 organic chemicals. Up to 0.24 parts per million (ppm) benzene (71432) and 1.34ppm trichloroethylene (79016) were detected. Total dust concentrations in two area samples were 0.35 and 0.56 milligrams per cubic meter. Accumulations of dust on surfaces and use of an open container for disposal of solvent wetted rags were observed. Noise levels ranged from 72 to 89 decibels. The authors conclude that no acute chemical exposure hazard was apparent with current chemicals and handling procedures. During long print runs, operators may be subject to excess noise exposure based on a standard of 85 decibels. Recommendations regarding duplicating facility ventilation, increase of fresh air supply, and housekeeping procedures are provided.

The Safety Division of the Department of Treasury requested the study which was performed on May 5, 1982. Four shooters at the Beltsville Range were exposed to an 8 hour average (TWA) lead concentration of 38 micrograms per cubic meter (microg/m3). During a 25 minute period they were exposed to a mean concentration of 720microg/m3. Two shooters at the Washington range were exposed to concentrations of lead ranging from nondetectable to 18microg/m3. One shooter was exposed to a copper TWA of 33.6microg/m3. The author concludes that a potential hazard from overexposure to lead did exist. However, the officers would rarely shoot on a daily basis, and ventilation design appeared adequate for normal use. Recommendations for limiting the use of lead bullets and improving ventilation are provided.

Area and personal samples were collected and former and current workers were radiographically screened for silicosis. The median concentration of respirable crystalline silica meter. The range was from undetectable amounts of dust to 350 micrograms per cubic meter. Concentrations in the silo and millroom exceeded NIOSH standards. Out of 47 past and present workers, complicated silicosis was diagnosed in 5 of the present workers and 1 of the former workers. All had been exposed to silica prior to 1972 when dirtier industrial processes had been employed in the facility. NIOSH recommends that general housekeeping be made more rigorous, that several leaks be repaired, and that dust concentrations be kept below the NIOSH standard by means of engineering controls. When concentrations exceed the standard respirators should be used. Industrial hygiene monitoring should be performed at least twice a year and medical records should be kept for at least 30 years after the termination of a worker's employment.

Total particulate concentrations ranged from 0.13 to 4.71 milligrams per cubic meter of air (mg/m3). The OSHA recommended exposure limit is 15mg/m3 for an 8 hour time weighted average. The author concludes that workers were not overexposed to total particulate concentrations, nor were they exposed to asbestos.

The managing postmaster requested the evaluation on behalf of an unspecified number of employees who developed medical problems. Evaluation was performed on August 3, 1981. The facility employed 31 workers. Environmental sampling indicated that all air and dust samples contained trace amounts of various metals. Nuisance dust concentrations of 0.02 and 0.04 milligrams per cubic meter were both well below the current (15 milligrams per cubic meter) nuisance dust standard. Carbon-monoxide and organic vapor concentrations were at normal background values. A fibrous glass and mineral wool combination was found in the ceiling tile. No asbestos or fibrous glass could be confirmed in any of the air or bulk dust samples. The author concludes that no health hazard existed at the facility. The author recommends good housekeeping procedures to keep airborne dust exposure to a minimum.

Management requested the evaluation on behalf of two workers. Four of six 12 hour breathing zone air samples exceeded the NIOSH standard for lead of 50 micrograms per cubic meter and ranged from 5 to 295 micrograms per cubic meter. Five of seven 12 hour breathing zone samples and one 2 hour sample exceeded the American Conference of Governmental Industrial Hygienists standard for silver of 10 micrograms per cubic meter. All iron-oxide fume, nitric-acid (7697372), nitrogen-dioxide (10102440), sulfur-dioxide (7446095), and sulfuric-acid (7664939) concentrations were substantially below the applicable evaluation criteria. Blood lead and free erythrocyte protoporphyrin results were all within acceptable limits. The author concludes that a health hazard due to lead and silver existed at this facility. He recommends the use of local ventilation systems, use of respirators, appropriate cleanup procedures, and medical monitoring of exposed workers.
