Abstract

With the development of the chemical industry, related accidents frequently occur, and fire and explosion accidents account for a large proportion. In order to prevent fire and explosion accidents, places that handle flammable liquids are classified according to the Korean Industrial Standards (KSC IEC60079-10-1) in accordance with the relevant laws. The same applies to laboratories dealing with flammable liquids. This paper verified the applicability of the procedure for classifying explosion hazard areas according to the Korean Industrial Standards when flammable liquid release from the laboratory to form an evaporative pool, and also verified the effect of a change in ventilation speed on the release characteristics. Through this, it was found that it was difficult to apply the criteria for the classification of places at risk of explosion according to the Korean Industrial Standards, and special safety measures should be prepared.

화학 산업의 발전에 따라 관련 사고가 빈번하게 발생하고 있으며 그 가운데 화재·폭발 사고가 큰 비중을 차지하고 있다. 화재 · 폭발 사고를 방지하기 위해 인화성액체를 취급하는 장소 등은 관련 법령에 근거하여 한국산업표준(KS C IEC60079-10-1)에 따라 폭발위험장소를 구분하도록 하고 있다. 이는 인화성액체를 취급하는 연구실에도 동일하게 적용된다. 본 논문에서는 연구실에서 인화성액체가 누출되어 증발 풀(pool)을 형성하는 경우 한국산업표준에 따른 폭발위험장소 구분 절차의 적용성과 환기속도의 변화가 누출특성에 미치는 영향을 확인하였다. 이를 통해 연구실과 같은 장소는 한국산업표준에 따른 폭발위험장소 구분에 대한 기준적용이 어려우며, 별도의 안전대책이 마련되어야 함을 알 수 있었다.
