최근 들어 발생한 가스사고 중 휴대용 부탄가스로 인한 사고가 상당한 비율을 차지하고 있고, 이로 인해 인명 피해가 많이 발생되고 있다. Among gas accidents that have occurred recently, accidents caused by portable butane gas account for a significant proportion, resulting in many casualties.

부탄가스는 식당, 가정집, 캠핑장 등 다양한 장소에서 사용되고 있으며, 다수가 모여 있는 장소에서 음식을 조리하다 사고가 발생되고 있다. Butane gas is used in various places such as restaurants, homes, and camping sites, and accidents occur while cooking food in places where a large number of people gather.

특히, 사고 유형은 휴대용 부탄가스의 파열과 폭발이 주된 요인으로 분석된다. 이러한 사고 발생으로 인해 정부에서도 부탄가스 안전장치의 개발과 보급 확대에 노력을 기울이고 있지만 시장 구조 상 안전장치를 부착할 경우, 생산단가가 현저히 높아져 소비자들의 반발이 예상되어 이에 대한 어려움을 겪고 있는 실정이다. In particular, the type of accident is analyzed as a major factor in the rupture and explosion of portable butane gas. Due to these accidents, the government is making efforts to develop and supply butane gas safety devices. However, if the safety devices are installed in the market structure, the production cost is significantly higher, and consumers are expected to backlash. .
