초록

정부는 2015년 보다 체계적이고 안전하게 화학물질을 관리하고 취급 할 수 있도록 법 제명 변경과 함께 「화학물질관리법」을 전부개정 하였으며, 특히 유해화학물질을 제조·저장·보관하는 취급시설의 설치 및 관리 기준을 대폭 강화하였다. 하지만, 일부 취급시설 기준의 경우 물리적인 공간부족과 시설개선과정 중 사고발생우려 등의 이유로 강화된 기준을 이행하기 어려운 상황이 생김에 따라 이러한 시설에 대해 2018년부터 "안전성평가"라는 특례를 운영하고 있다. 본 연구에서는 유해화학물질 누출궤적 평가모듈 개발을 통해 현장에 설치된 염산과 황산 저장탱크의 방류벽 높이 적정성을 검증하고 이격거리에 따른 방류벽 높이를 제시하였다. 이를 활용하여 산업현장에서는 보다 손쉽게 해당 취급시설의 안전성 평가 특례신청이 가능할 것으로 판단된다. 또한, 본 연구의 결과는 유해화학물질 취급시설의 설계에도 활용하여 유해화학물질 취급시설의 안전성 향상에 기여할 것으로 기대된다.

The Chemical Control Act of 2015 was enhanced to ensure the safe management of hazardous chemicals. In particular, there have been substantial changes in the standards for the installation and management of handling facilities for manufacturing and storing hazardous chemicals. However, some standards for handling facilities are difficult to implement due to a lack of physical space or because of safety accidents during facility improvements. Therefore, the Safety assessment system (SAS) has been operating for such facilities since 2018. This study developed a leakage trajectory evaluation module that can easily evaluate the outside of a dike for safety evaluation. We analyzed two case studies on a dike for hydrochloric acid and sulfuric acid storage tanks with this module and suggest a reasonable plan for the facility. We believe that it will be possible to more easily submit SAS reports at chemical plants by using this evaluation module. This study is expected to contribute to the improvement of the safety design of hazardous chemical handling facilities.
