In response to a request from the National Centers for Environmental Health (NCEH), NIOSH investigated occupational exposures to methyl- tert-butyl-ether (1634044) (MtBE), benzene (71432), xylene (1330207), toluene (108883), and carbon-monoxide (630080) (CO) at worksites where workers were exposed to gasoline (8006619) and exhaust emissions. Eleven facilities in Fairbanks were surveyed during February of 1993, including automobile dealerships, automotive repair facilities, service stations, and agencies in which workers were exposed during refueling and driving vehicles. Personal breathing zone and area air samples were collected for analysis. Exposure to toluene and xylene ranged from less than 0.03 to 2.99 parts per million (ppm) and from less than 0.02 to 15.7ppm, respectively. MtBE exposure levels ranged from less than 0.03 to 0.45ppm. Benzene concentrations ranged from 0.02 to 0.57ppm. Carbon-monoxide levels ranged from none detected to 69ppm. The author concludes that workers were exposed at these sites to potentially hazardous levels of benzene and carbon-monoxide. The author recommends measures to reduce worker exposures.
