Comparative study on Korean and international chemical control regulations of the physical hazards of sodium cyanide and hydrogen cyanide

This study highlights existing problems and system improvements within the Accident Precaution Chemical Codes (APCC) in Chemicals Control Act (CCA, 2015) of Korea for the physical hazards control of sodium cyanide and hydrogen cyanide. We carried out comparative analyses with international industrial safety regulations, focusing on regulations within the U.S.A. and E.U. Previous technical studies and reviews of the regulations, which were referenced in this paper, have evaluated their clarity and interpretation. This paper focused on categorizing similar components from the different regulations of each country in terms of regulatory characteristics. The collected information was then assessed, defining each components merits and demerits in accordance with criterion which had been adopted in advance. The analyzed components were then used to improve current regulatory limits of the physical hazards control of sodium cyanide and hydrogen cyanide in Korea. The proposals of this exploratory study should provide guidance for future regulatory codes allowing a greater ease of interpretation and compliance by stakeholders.
