DISCUSSION ON THE RISK OF ACCIDENT DETERMINED WITH ACCIDENTS DATA OCCURRED IN CLASSROOMS OF ELEMENTARY/JUNIOR HIGH SCHOOLS AT TOKYO

The data of accidents in the junior high schools and the elementary schools in the ward areas and the urban districts of Tokyo were investigated with considering the meteorological data of relevant areas and the rate of air conditioners being placed in classrooms. The rate of air conditioners being placed in classrooms in the ward areas of Tokyo was four-six times higher than that in the urban districts of Tokyo. The data of accidents of the elementary / junior high schools were obtained from the NAASH (National Agency for the Advancement of Sports and Health), and the period of analysis was set as 3 years from 2005 to 2007. The data of accidents linked with meteorological data were classified for each level of the outside temperature at the time of occurrence of the accident. From this the relation of the outside temperature and the occurrence rate of accidents were determined. While the occurrence rate of accidents in classrooms in the ward areas during summer period was decreased with the years from 2005 to 2007, that in the urban districts was constant with the years. It was found that the difference in the rate of air conditioners being placed in classrooms might have an effect on the occurrence rate of accidents in the classrooms. The effect in the elementary schools could be greater than that in the junior high schools. .
