초록

지정(특수)폐기물로 처리되어야 할 폭발성 폐기물이 일반폐기물 처리장에 잘못 반입되어 폐기물 처리과정에서 폭발사고로 이어졌을 때 많은 인명과 재산피해가 수반되므로 향후 폐기물 배출업체는 처리에 적합 가능한 처리시설로 폐기물을 처리하여야 한다. 본론에서 언급한 바와 같이 화약류 포장재 폐기물(고체부타디엔)의 착화재연실험에서 모두 발화위험성이 확인되었고, 작은 점화원에도 쉽게 착화되어 급속하고 폭발적으로 연소되는 형태를 나타냄을 알 수 있었다. 특히 폐기물처리장에서의 화약류 포장재에 의한 화재 폭발사고 사례와 같이 화약류 포장재 폐기물이 소각폐기물처리장에 대량으로 반입되어 유기화합물 폐기물과 혼재되어 있을 때는 상호 산화반응과 열분해 등으로 가연성, 산화성 가스가 발생되어 스파크 등 점화원에 의해 착화되며 순간적으로 폭발로 이어지는 개연성이 있음을 확인 할 수 있었다. 본연구가 화재현장에서의 현장 감식에 있어서 작은 참고자료가 되었으면 하는 바람과 과학적인 발화원인 판정으로 소방기관이 화재조사 전문기관으로서 대외적인 공신력을 인정받고 신뢰성 향상에 기여하는 계기가 되기를 기대한다.

when the explosive wastes to be treated as designated wastes are brought into the wastes treatment plant by mistake and lead to an explosion in the wastes disposal process, many people and property damage are involved. Waste should be treated properly. As mentioned in this paper, ignition reac- tion tests of ignitable re-burning of explosives packing material waste (solid butadiene) confirmed that ignition was easily occurred, and that even small ignition sources were easily ignited and burned quickly and explosively. In particular, when explosives are loaded into incineration wastes in large quantities and mixed with organic compound wastes, such as fire and explosion accidents caused by explosives packing materials at waste disposal sites, flammable and oxidative gases are generated due to mutual oxidation and pyrolysis It is confirmed that there is a possibility that ignition sources such as spark ignite and instantaneously lead to explosion. It is hoped that this study will be a small reference for on - site detection in the field of fire, and it is expected that the fire - fighting agency will be recognized as a fire investigation agency and will contribute to the improvement of the credibility.
