사고대비물질 중 일부 유기용제 함량기준의 지정기준 선정에 관한 연구

Abstract

The designated criteria for concentration limit for substance requiring preparation for accidents is not clearly specified under the Chemicals Control Act. In this study, the target substances are five organic solvents (methyl alcohol, benzene, methyl ethyl ketone, toluene and ethyl acetate), which are toxic substances and substance requiring preparation for accidents. All five concentration limit of toxic substances is 85%. On the other hand, concentration limit of substance requiring preparation for accidents of both methyl ethyl ketone and ethyl acetate is 25% and other threes is 85%. In order to find out whether these concentration limits are appropriate or not, legal standards, physical dangerous, acute toxicity, occupational exposure levels, circulation and emissions volume were investigated. As a result of comparative evaluations, it was found that all five had similar physical dangerous and methyl ethyl ketone and ethyl acetate had less humans hazards than the other three. Therefore, it was judged that it is appropriate to amend the concentration limit of 5 target substances to be same.
