Abstract

최근 전자제품 생산업체에서 EPS를 직접생산하게 되면서 EPS 공정이 증가하고 있다. EPS에는 펜탄이 포함되어 있으며, 펜탄은 하이브리드 혼합물로 구분할 수 있어 높은 화재폭발의 위험성을 가지고 있다. 각 공정별 펜탄의 누출률은 발포기, 사일로실, 저장실 순이나 발포기의 경우 일반적으로 밀폐되어 있으므로 사일로 실이 가장 화재폭발 위험성이 높다고 판단하였다. 사일로실의 누출률 중 70%는 사일로 상단을 통해 누출되며, 사일로 상단을 통해 누출되는 펜탄의 거동을 분석하여 사일로실 위험성 완화대책을 수립하였다. 1. 폭발위험구역 2종으로 관리, 2. 사일로상단 50cm이내 환기설비 설치 또는 Push-Pull 구조의 환기설비설치, 3. 사일로 하단 1.4m이내에 가스감지기 설치, 4. 60%이상의 습도유지
