Abstract

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.

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 제도를 운용해야 한다. 하지만 현행 산업안전보건법에는 인화성을 띠는 저온액화 물질에 적용하기엔 적절하지 않은 기준이 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 7개 항목이 어떤 방향으로 개선되어야 하는지 도출하였다.
