This study examines the risks posed by the on-site reactivity of hazardous chemicals, focusing on high-risk accident scenarios and response system improvements. Using cases like TATP and VX, it analyzes the accessibility and combination potential of precursor chemicals that are not inherently hazardous but can become highly dangerous under specific conditions. Scenario-based qualitative risk assessments reveal critical gaps in South Korea’s current safety management, including insufficient anticipatory regulations, limited detection capabilities for reactively synthesized agents, and fragmented inter-agency coordination. The study highlights the need for a proactive, integrated approach incorporating real-time precursor tracking, advanced detection technologies, and joint scenario-based response training. By shifting from static substance control to risk-based preparedness, this research offers strategic recommendations for enhancing chemical accident prevention and response in complex facility environments.

우리나라는 삼면이 바다로 이루어져 있고, 이에 따라 많은 해양 시설로 인한 위험유해물질이 배출되고 있으나, 배출관리 및 규제 시스템이 미비한 상황이다. 따라서, 위험유해물질(HNS) 관리를 위하여 효율적으로 데이터를 수집할 수 있는 시스템이 필요하 다. 본 연구에서는 HNS 데이터를 효율적으로 관리 및 저장하기 위한 데이터 표준화 시스템을 설계하고 이의 표준화 방안을 제시하고 자 한다.
