우리나라의 승강기 보유 대수는 2023년 12월 기준 약 84만 대로 세계 7위에 달하며, 매년 약 3.1만 대의 신규 승강기가 설치되어 세계 3위의 승강기 대국으로 자리 잡고 있다. 승강 기의 지속적인 증가와 함께 고장 및 사고도 꾸준히 증가하고 있으며, 2022년 소방청의 구조 활동 분석에 따르면 승강기 사고 및 고장으로 인한 구조 인원은 23,856명에 달하고, 119 출동 건수는 33,114건에 이른다. 이로 인해 발생한 사회적 안전 비용은 약 340억 원으 로 추정된다. 본 연구는 2019년부터 2023년까지 최근 5년간 한국승강기안전공단에 접수 된 96,577건의 고장 데이터와 330건의 사고 데이터를 활용하여 승강기 고장과 사고 간의 상관관계를 분석하였다. 지역별, 용도별, 연도별 분석을 통해 고장률과 사고비율 간의 관 계를 파악하고, 통계적 상관분석을 통해 고장이 반드시 사고로 이어지지 않음을 확인하였 다. 특히 고장률과 사고율 사이에 명확한 양의 상관관계가 나타나지 않았으며, 일부에서는 음의 상관관계가 도출되었다. 이러한 결과는 승강기 고장과 사고가 개별적으로 관리되어 야 하며, 고장이 발생하더라도 철저한 유지관리와 안전조치에 따라 사고 발생은 예방 가능 하다는 점을 시사한다.

As the duty to report and investigate major elevator failures has expanded due to the total amendment of the Elevator Safety Management Act in 2018, more important information on major elevator failures that have been partially identified has been collected. As of 2019, the number of elevators in Korea exceeded 700,000, making it the eighth-class elevator powerhouse in the world, but there is a trend of increasing casualties due to accidents and breakdowns. An Seung-gang-gi is a term that encompasses an elevator that moves vertically and an escalator that moves horizontally. It is an important means of transportation for most citizens that are encountered almost every day in daily life, and it is also necessary as a means of transportation that enables the construction of skyscrapers. And it seems that its importance will never diminish in the future. Major elevator failures are the main cause of dispatch when accumulating the number of 119 dispatches, and the frequency of occurrence is high. It's a shame. According to Heinrich's Law, 300 minor signs and danger phenomena precede, 29 minor accidents and 1 major accident. Accidents caused by elevators are increasing every year due to the increase in the number of installations, and the damage is threatening the valuable lives and property of users and workers in related fields due to fatal risks such as death and serious injury. Elevator safety management can achieve its purpose only when it is managed with the usual interests, awareness of safety, and full efforts of the users, workers, and the government concerned. This study was analyzed based on 2019 data notified to the Korea Elevator Safety Agency on major breakdowns improved after the revision of the Elevator Safety Management Act in 2018, and a total of 8,256 data were analyzed using the SPSS 21 version, a statistical analysis tool, to analyze the correlation with technical statistics. Proceeded. Through the analysis, it was possible to obtain preventive safety management data to prevent serious elevator safety accidents from occurring, and to derive meaningful implications that related safety management and maintenance can be effectively operated to prevent serious failures. In addition, through this analysis, we expect the development of related industries and legal and institutional improvement.

An accident related with elevators can cause death or serious injury of operators or passengers. This kind of a fatal accident is due to a failure of elevator. The reduction of failures of elevators is important to reduce the occurrence of elevator accident. Thus, this paper presents the results of analysis for the failure of elevators using the failure data of elevator. The results of analysis can be used to make a maintenance process of elevators.
