Abstract
In response to a request for technical assistance from the National Centers for Environmental Health (NCEH), NIOSH evaluated airborne concentrations of methyl-tert-butyl-ether (1634044) (MtBE), benzene (71432), xylene (1330207), and toluene (108883) in workers exposed to gasoline (8006619) and exhaust emissions at an indoor parking garage, a medical taxi company, an automobile dealership/repair shop, an auto repair shop, and a state highway maintenance garage (SIC-4173). Twenty four personal breathing zone samples were analyzed. Toluene and xylene exposures ranged from less than 0.03 to 0.73 parts per million (ppm) and less than 0.02 to 0.43ppm, respectively. MtBE exposure levels ranged from less than 0.03 to 0.14ppm. Benzene concentrations ranged from less than 0.006 to 0.054ppm. The author concludes that workers were not exposed to airborne concentrations of these chemicals in excess of the relevant occupational standards. The author recommends the use of additional administrative and engineering controls to reduce worker exposures to solvents.
