According to the third study on the distribution of chemical substances carried out by the Department of Environment in 2006, there were a total of 900 chemical substances whose respective annual usage amount exceeded 1,000 tons and, among them, 90 substances belonged to the 168 hazardous substances requiring management(53.6%). The work-related illnesses caused by hazardous substances requiring management in Korea between 1992~2005 can be classified into four groups depending on the type of the chemical substances. These four groups are 23 organic substances including benzene, 12 metals including lead, 3 acids and bases including hydrogen chloride, and 6 gaseous substances including carbon monoxide. These hazardous substances requiring management were again classified depending on the threshold limit values. The chemicals whose TLV was lower than or equal to 0.005 ppm included 4 organic substances including methylene bisphenyl isocyanate and toluene-2,4-diisocyanate (TDI). The chemicals whose TLV was larger than 51 ppm included 22 organic substances including diethyl ether and 1,2-dichloroethylene. When we classified these hazardous substances requiring management according to the categories of GHS health hazards, we found that isobutyl acetate and magnesium oxide didn’t belong to the 13 health hazard categories. Among the substances whose TLV is set and whose annual usage amount is more than 0.1 million ton, we recommended 12 chemical species including 4,4’-Methylenedianiline as new hazardous substances requiring management. All the recommended substances were found to be hazardous when we classified their health hazards.
