The report summarizes over 2,000 occupational exposure data on benzene, measured in the period 1986-1992. Exposures for the various types of jobs are reviewed against a number of time-weighted average (TWA) criteria, including 1 ppm and 0.5 ppm. Most of the 8-hour TWA exposures were below 1 ppm and 62-100% at, or less than, 0.5 ppm, depending on the job being undertaken. The results are similar to those found in a survey conducted in 1977-85.
