초록

이 연구는 내용연수에 따른 분말소화기 저장용기의 부식정도와 소화성능 변화를 고찰하여 상시 적정 성능을 확보하기 위해 시장지역, 공장지역, 공동주택지역을 대상으로 실험을 실시하여 다음과 같은 결론을 도출하였다. 첫째, 외부접촉 저장용기 부식 정도에 대한 실험값이 2012년 공동주택지역에서 부적합으로 나타났다. 둘째, 소화기 내구연한은 10년이나 1회에 한하여 샘플검사에 통과하면 길게는 13년을 사용하게 되지만, 사실상 소화기 수명은 배치장소의 주위환경 과 내용연수에 따라 차이가 크게 다르게 나타나는 것으로 분석되었다. 마지막으로 소화기 배치장소의 환경이 취약한 경우에는 더욱 빠르나, 통상적인 관리하에서 소화기의 내용연수 7~8년부터 소화기 저장용기의 부식이 일어나기 시작하므로 소화기의 내용연수를 5년 정도로 줄이는 것이 타당하다고 판단된다.

This study presented the criteria for analyzing the corrosion of the powder extinguisher storage container according to the useful life, and conducted an experiment on the market area, the factory area, and the apartment building area to ensure proper performance at all times and drew the following conclusions.First, the experimental value for the degree of corrosion of external contact storage containers was found to be unsuitable in the factory area in 2014. In 2012, the experimental value for the degree of corrosion of external contact storage containers in apartment complexes was found to be inappropriate. Second, the experimental value for the dropout of the external paint in the storage container was found to be inappropriate in the factory area in 2014. In 2012, the experimental value of the degree of coating of the external paint storage container in the apartment building area was found to be inappropriate. It was analyzed that the useful life of the fire extinguisher is 10 years, and if it passes the sample test only once, it will be used for up to 13 years, but in fact, the difference varies greatly depending on the surrounding environment of the fire extinguisher place. Since the degree of corrosion of the storage container of the fire extinguisher from 8 years of the fire extinguisher's useful life is clearly decreased, it is judged that 5 years of the fire extinguisher is appropriate.
