수소 수요가 증가함에 따라 수소를 저장하기 위한 설비의 중요성이 대두되었으며, 국내에서는 다양한 법으로 수소 취급 설비를 규제하고 있다. 산업안전보건법에 따르면 저장량 5톤 이상의 액화수소를 취급하는 경우 공정안전관리 제 도를 운용해야 한다. 하지만 현행 산업안전보건법에는 인화성을 띠는 저온액화 물질에 적용하기엔 적절하지 않은 기 준이 있다. 본 연구에서는 산업안전보건법과 KOSHA Guide를 바탕으로 PSM 구성요소 중 공정안전자료와 안전운전 계획에서 수소취급 설비를 위해 개선되야 할 7개 주요 항목에 대해서 제시하였으며, 과학적인 분석을 통해 제시된 7 개 항목이 어떤 방향으로 개선되어야 하는지 도출하였다.
As the demand for hydrogen increases, the facilities for storing hydrogen has been important, and a few laws for hydrogen facilities should be complied. According to the Occupational Safety and Health Act in Korea, in case liquid hydrogen with a storage capacity of 5 tons or more is handled, a Process Safety Management (PSM) system should be complied. However, there are some standards which are not proper for flammable low-temperature liquefied substances on the current Occupational Safety and Health Act. In this study, 7 key points in process safey information and safety operation procedures among PSM components are suggested and how these key points should be improved is derived based on scientific analysis.
