The number of building maintenance companies have increased since 1960 because buildings of which total floor area exceeds 3,000 m^2 are required certain degree of indoor air quality by laws. The general population of workers in BMS has a peak in the eldelies, and more elderly workers are expected to engage in BMS. However, detrimental environments in the working space and the daily demand for workers may cause physiological and psychological stress. It was therefore reported that accidents involving elderly workers have frequently happened during working. In this study, environments in working place and physiological and psychological stress to elderly workers in janitor services were evaluated. Results are as follows ; 1) Workers in janitor services walked in the distance of 4,000m - 8,000m a day. 2) Elderly workers claimed chronic fatigues such as back or knee pains. 3) Elderly workers showed their physical characteristics that restrain ankle movements. 4) The main cause of accidents may be workers' careless mistakes.
