Abstract Risk management of major hazardous installations (MHIs) is a principal concern due to chemical hazards, both in South Korea and in foreign countries where chemical plants are located. To cope with these risks, various regulatory schemes have been developed for the recognition, prevention, and control of chemical accidents. Despite these efforts, the worst major accident caused by massive (20 t) leakage of anhydrous hydrogen fluoride occurred in Gumi City in 2012. As a result, the location of MHIs associated with the chemical industry became a major concern among the public, relating to the risks to both the public and environment. In this study, the regulatory systems in South Korea are compared with global standards for controlling major hazards, and the adoption of land use planning (LUP) is discussed. Based on population statistics for the last 17 years, the EPA's ALOHA software was used to evaluate the impact of land development and population growth around MHIs through case studies of societal risk changes at five water-treatment plants using Cl2 (chlorine). The total risk at the Cl2 sites increased by up to 3.05 times from 2000 to 2017, demonstrating the necessity of introducing LUP.

韩国主要危险设施周围人员面临的风险增加以及土地利用规划的必要性

摘要 主要危险设施 (MHI) 的风险管理是化学危害的主要问题，无论是在韩国还是在化工厂所在的国外。为了应对这些风险，已经制定了各种监管计划来识别、预防和控制化学品事故。尽管如此，2012 年龟尾市发生了最严重的无水氟化氢泄漏（20 吨）重大事故。 因此，与化学工业相关的 MHI 的位置成为公众的主要关注点，与对公众和环境的风险。在这项研究中，韩国的监管体系与控制重大灾害的全球标准进行了比较，并讨论了土地利用规划 (LUP) 的采用。根据过去 17 年的人口统计数据，EPA 的 ALOHA 软件通过对五个使用 Cl2（氯）的水处理厂的社会风险变化的案例研究，评估了 MHI 周围土地开发和人口增长的影响。从 2000 年到 2017 年，Cl2 站点的总风险增加了 3.05 倍，表明引入 LUP 的必要性。
