Abstract

There have been 3E problems of energy, economy and environment since the earth has its history. Especially, 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. Consequently, this study tries to find out the influence of flame caused by the explosion of butane canister on the adjacent combustibles and people by simulating relevant quantity of TNT. In addition, the damage estimation was conducted by using API regulations. If the scale of the radiation heat is known by calculating the distance of flame influence from the explosion site, the damage from the site can be easily estimated. And the accident damage was estimated by applying the influence on the adjacent structures and people into the PROBIT model. According to the pro bit analyze, the spot which is 50cm away from the flame has 97% of the damage probability by the first-degree burn, 8% of the damage probability by the second-degree burn and 4% of the death probability by the fire.

지구상에 역사가 시작된 이후로 에너지, 경제, 환경 등 3E 문제가 존재해 왔다. 특히, 산업사회의 발전과 더불어 인간의 삶에 대한 욕구도 날로 급속하게 변하고 있다. 주40 시간제가 시행되면서 야외활동을 즐기는 사람들이 많아지고 있다. 가스에 의한 사고도 토요일과 일요일에 가장 많이 발생하고 있다. 따라서 본 논문에서는 부탄 캔의 파열에 따른 화염의 영향으로 인간에게 미치는 영향을 알아보고자 한다. 이를 위하여 API에서 규정한 피해예측을 통하여 평가를 실시하였다. 폭발장소에서의 화염에 의해 미치는 영향 거리를 산출하여 거리별 복사열의 크기를 알게 되면 그 지점에서의 피해는 간단하게 예측할 수 있다. 또한 폭발장소 주변에 위치한 인간에게 미치는 영향을 PROBIT 모델에 적용하여 사고피해예측을 평가하였다. 프로빗 분석에 의하면 화염에서 50cm 이격된 곳은 1도 화상에 의한 손상확률이 97%, 2도 화상에 의한 손상확률은 8%, 화재로 인한 사망확률은 4%로 나타났다.
