Abstract

Two asbestos slate manufacturing and seven asbestos textile plants in Korea were surveyed from May 20 to July 2, 1987. The purposes of this study were to evaluate 1) worker exposure to asbestos, 2) compliance to the standards and 3) the efficiency of existing local exhaust systems. Sixty-two personal samples and eighty-three area samples were collected and analyzed using "NIOSH 7400" method. Results of this study were as follows. 1. The asbesots exposure concentrations in asbestos textile plants were 1.3 - 14.3 fibers/cc(geometric mean(GM), 4.4 fibers/cc). 2. Worker exposure level to asbestos fiber in asbestos slate manufacturing industry was 0.21 fibers/cc during wet processing, which is below the Korean Standard of 2 fibers/cc. 3. Most local exhaust systems installed in asbestos textile plants were inadequately designed. 4. Ninety-six percent of the 145 samples exceeded the U.S. Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL) of 0.2 fibers/cc and forty-nine percent of the samples exceeded the Korean Standatd of 2 fibers/cc.
