Abstract
The number of the lifts installed and used in Korea totals up to 526,676 units as of the end of December 2014, due to the development and urbanization of this country. Since the lift is one of the convenience facilities and especially a kind of essential transportation facilities used by a majority of passengers everyday, it is necessarily required to manage the lift safety. Therefore, this study aims to determine the 5 factors(kinds of lifts, ages of victims, causes of accidents, seasons in accidents, usages of buildings) affecting the types(caught in, trip over, falling, collision) and the injury levels(death, serious injury, minor injury) of the lift accidents based on the analysis of the total victims of 1,514 people due to the 1,146 accidents which have occurred for the past 15 years, and to find the frequency and ratio of each factor in the accidents, and to make a correlation among the factors. As the result of the analysis, it shows that there exists a statistically significant correlation among the factors.
