The purpose of this study is to evaluate the human impact of falling debris of tempered glass for school. In this study, influence of glass debris on human was confirmed by experiment using pig skin. Glass debris of 3.35 to 8.0 mm in size were more than two-thirds of the total. As a result of dropping 100 cases on the pig’s skin, 20 cases were found the scratches on the skin. The larger the weight and speed of the glass debris, the more the scratch tended to increase.
