Abstract

As the industrial society is highly developing, human need in daily life has also changed drastically. With the introduction of 40 hour working week system, more households enjoy picnics on weekends. More gas accidents take place on Saturdays and on Sundays than any other days of week. In this context, the Institute of Gas Technology Training in Korea Gas Safety Corporation carries out explosion experiment to make trainees to take all possible measure to ensure safe management of gas in the field by fully recognizing the hazards of gas explosion accidents. In this study, the influence of explosion over-pressure caused by the rupture of butane can thrown away after use was calculated by using the Hopkinson's Scaling Law and the accident damage was estimated by applying the influence on the adjacent people into the Probit model. The value of those away from 50 meters from the explosion site was 1.35kPa and the peak overpressure to thoes away from 25 meters directly was 3.2kPa. Those value was input to the PROBIT model, the estimation showed the sante result 0 percent of damage possibility.

산업사회의 발전과 더불어 인간의 삶에 대한 욕구도 날로 급변하고 있으며, 주 40시간제가 도입되면서 피크닉을 즐기는 세대가 늘어나고 있는 실정이다. 또한 가스에 의한 사고는 토요일과 일요일에 가장 많이 발생하고 있다. 따라서 가스안전교육원에서는 이러한 가스의 폭발사고에 대한 영향이 매우 위험하다는 것을 교육생에게 알려 현장에서 가스안전관리에 만전을 기하도록 하고자 폭발실험을 실시하고 있다. 본 논문에서는 이러한 폭발실험으로 교육에 참관하는 교육생에게 미치는 영향을 알아보고자 폭발로 인한 과압은 Hopkinson의 삼승근법을 이용하여 계산하고, 인간에게 미치는 영향은 Probit 모델에 적용하여 사고피해예측을 평가하였다. 폭발위치에서 50m 떨어진 곳에서의 피크과압은 1.35kPa이고, 25m 떨어진 곳에서는 3.2kPa이다. 이 값은 Probit 모델에 적용하면 손상가능성이 0%로 나타났다.
