A STUDY ON THE CHARACTERISTICS OF WORKING ENVIRONMENTS AND ACCIDENT FACTORS IN CLEANING WORKS OF BUILDINGS

This research focuses on cleaning works as one type of building maintenance works, and aims to identify the factors that trigger industrial accidents, through monitoring the current state on the working environment of cleaning workers and its relationship to their physical burden. Specifically, this paper clarifies the working environment of the cleaning workers, based on the results of the survey of multiple buildings that outsource cleaning work to building maintenance service companies. In addition, the characteristics of working environments are categorized into three groups of “Former Middle Facilities”, “New Small Facilities” and “Large Facilities”, in line with the working environments and facility characteristics of the buildings surveyed. This is followed by a survey on the physical burden of the buildings in each categorized group. Psychiatry, physical fatigue, industrial accidents and the experience of risks those have the possibility of triggering industrial accidents are analyzed for each group, to identify the relationship between the working environment and the physical burden.
