Abstract

Fatal injuries and deaths have occurred resulting from the operation or disassembling of a powder extinguishers in Korea. If a rusted powder extinguisher is exploded during operation or disassembling, it rises to the air like a rocket and hits a head, chest, or neck part of an operator, resulting in his (her) death or injury. In this study examines the explosion accident cases of a powder fire extinguisher and analyzes their causes, reactions to explosion, and precautionary measures. And in this paper suggests 1) no using of old fire extinguishers in fire drill or education, 2) education and public information on danger of old fire extinguishers, 3) indication of explosion danger to cartridge-type dry chemical powder fire extinguishers had already placed to buildings etc., 4) obligatory indication of durable years on fire extinguishers, 5) examination for introduction of system that do hydraulic pressure test about fire extinguishers that given period past, 6) construction of system that reclaim old fire extinguishers, 7) construction of system that recycle or reuse old fire extinguishers, and 8) operation of help desk related to old fire extinguishers as precautionary measure of fire extinguisher explosion accidents.

분말소화기를 조작하거나 해체하는 과정 중에 아주 드물게 사상자가 발생하는 경우가 있다. 부식된 분말소화기는 조작 중 또는 해체(폐기)과정 중에 폭발하면 로켓과 같이 위쪽으로 솟아오르면서 소화기 조작자나 해체과정 중인 사람의 머리나 가슴, 목 부위 등을 쳐서 사상사고를 발생하게 한다. 이 논문에서는 분말소화기파열사고사례를 알아본 후, 파열사고의 원인과 파열로 인한 반동력, 예방대책에 대해 알아보았다. 소화기 파열사고의 예방대책으로 훈련이나 교육에 부식된 소화기의 사용 자제, 부식된 소화기에 대한 위험성 교육 및 홍보, 기설치 가압식분말소화기에 파열위험성 표시, 내용연수 표시 의무화, 일정기간 경과 소화기에 대한 수압검사 제도의 도입 검토, 폐소화기 회수시스템 구축, 폐소화기의 재활용시스템 구축, 노후소화기관련 상담창구 운영 등을 제안하였다.
