가스폭발위험장소의 설정에 관한 기술지침
1. 목 적
이 지침은 「산업안전보건기준에 관한 규칙 제230조(폭발위험이 있는 장소의 설정
및 관리)」에 따라 인화성의 액체, 가스 또는 미스트를 취급하는 장소에서의 전기설비
의 적절한 선정 및 설치를 위한 가스폭발위험장소(이하 ‘폭발위험장소’라 한다)의 설정
에 관한 기술 사항을 정함을 목적으로 한다.
2. 적용범위
(1) 이 지침은 정상대기상태에서 공기와 혼합되어 있는 인화성의 액체, 가스 또는 미
스트의 존재로 인하여 발화위험이 조성될 우려가 있는 장소에 적용한다.
(2) 이 지침은 다음의 경우에는 적용하지 아니한다.
(가) 폭발성 갱내가스가 존재할 우려가 있는 광산
(나) 폭발성 물질의 제조 및 취급공정
(다) 이 지침에서 다루는 비정상(Abnormal) 상태를 벗어나는 매우 드믈거나 치명
적 고장(이 지침의 3.(1)(저) 및 (처) 참조)
(라) 의료용으로 사용되는 공간
(마) 저압의 연료가스가 취사, 온수 기타 유사한 용도로 사용되는 상업용 및 산업
용 기기(Appliances), 다만 해당설비(Installation)가 관련 도시가스사업법에
부합되는 경우에 한함
주) 도시가스의 경우 관련법에 따라 "저압"은 0.1 MPaG(게이지 압력) 미만을 말한다.
(바) 주거 공간 및 시설(Domestic premise)
(사) 가연성 분진 또는 섬유로 인한 폭발위험의 우려가 있는 장소(KS C IEC
60079-10-2 참조)
