Abstract
In response to a request from the United Steelworkers of America, Local 15320, an evaluation was conducted of possible hazardous working conditions at Allied Chemical Company Green River Works (SIC- 1474), Green River, Wyoming. Trona mining was carried out at the site; the facility employed approximately 1,300 people, with about 1,000 of these being miners and maintenance personnel. An industrial hygiene survey was conducted over three shifts on 2 days. Ambient air samples were collected for total dust, respirable dust, free silica (14808607), trace metals, asbestos (1332214), ammonia (7664417), nitrogen-dioxide (10102440), particulate aromatic hydrocarbons and formaldehyde (50000). Trona alkalinity was also measured. Some excessive levels were noted for total dust and ammonia. There was no asbestos or crystalline silica found, and exposures to trace metals, formaldehyde and nitrogen-dioxide were not considered significant. Other contaminant levels were insignificant. The author notes that trona should be considered a primary skin irritant, able to produce contact dermatitis. The author recommends that efforts be made to reduce contact with trona, that cartridge respirators for ammonia should be available during tamping and after blasting, and that ventilation and respirators be used to reduce total dust exposure in underground mining activities.
