Abstract

Chloric acid is a toxic chemical and the risk of facility handling chloric acid was assessed from the list of accident scenario to provide countermeasure to keep the vicinity safe. Accident scenarios were listed by using MSDS and process safety information. The scenarios having effect to the off-site were selected and assessed further according to guideline provided by Korea government. Worst case and alternative scenarios including other interested scenarios were evaluated using ALOHA. Each evaluated scenario was assessed further considering countermeasures. The results showed that the facility handling chloric acid is safe enough and needed no further protections at the moment.

위험물인 염산을 취급하는 사업장에서 발생할 수 있는 사고를 알아내고 사고시 인근에 미치는 영향을 평가하여 어느 정도 위험이 있는지 알아보며 이에 대한 대비책을 적용하고자 하였다. 취급 화학물질 정보와 공정정보로부터 사고 시나리오를 선정하고 염산 누출시 사업장외로 영향을 미치는 사고 시나리오를 선정하여 환경부의 지침에 따라서 ALOHA를 활용하여서 평가하였다. 최악의 사고 시나리오를 비롯한 사고 시나리오를 평가하였으며 이들의 사고시 피해완화대책도 살펴보았다. 평가결과 염산생산시설은 현재의 안전조치가 충분하여서 추가의 개선대책이 필요하지 않은 것으로 판명되었다.
