Assessment of worker exposure to benzene in gasoline distribution terminals was performed using passive dosimeters coupled with a gas chromatographic technique to allow the detection of benzene at 0.001 ppm for an eight-hour exposure. There were four terminals surveyed. Personnel sampling times were the duration of the work shift, which ranged from 8 to over 12 hours. In addition, two area samples were also taken at one of the terminals. As a group, the truck drivers had the highest benzene exposure. The mean concentration was 0.127 +- 0.058 ppm for 19 drivers surveyed. These product drivers on the average transported 5 to 7 loads per shift. The non-office workers, totaling ten, which include mechanics, leadmen, warehousemen and garage mechanics in the same facilities had the second highest exposure to benzene. The average concentration was 0.076 +- 0.062 ppm. Office workers, including managers, supervisors and clerks, had the least exposure, with an average benzene level of 0.040 +- 0.021 ppm for the group of 7. The two area samples showed an average concentration of 0.094 ppm benzene, approximating the general exposure level of workers within the facility. Based on these data, worker exposure to benzene in bulk terminals is well below the OSHA recently reduced exposure limit of 1 ppm for an eight-hour time-weighted average.
