Abstract: Objectives: This study was to investigate the signs and notations of skin absorption, carcinogenicity, germ cell mutagenicity, and reproductive toxicity in the occupational exposure limits of Korea and of other advanced countries. Methods: Information on occupational exposure limits in Korea, the USA, the UK, Germany, and Japan was investigated through the Internet, and items marked as carcinogenicity and skin absorption were compared by country. Results: Legal occupational exposure limits have been greatly simplified. However, in the case of HSE WEL, skin absorption, carcinogenicity classification, sensitization, and in the case of DFG MAK, skin absorption, carcinogenicity, pregnancy risk group, germ cell mutagenicity, airway and skin sensitization, photo contact sensitization, and vapor pressure were provided. Conclusions: It is desirable to indicate the carcinogenicity and skin absorption within permissible limits, and to include information on critical effects in chemical substance exposure limits to uphold the right to know of industrial hygienists and workers in Korea. It is also necessary to clarify the precautions, limitations and protections for skin absorption.
