Firemen began rescuing children from the second-floor windows, but nightmare conditions in some of the classrooms had already become unbearable. Children were stumbling, crawling, and fighting their way to the windows, trying to breathe and escape. Many jumped, fell, or were pushed out the windows before firemen on ladders could reach them. Children jumped with their hair and clothes on fire. Some died later as a result of the fall, and several more were seriously injured. Many of the smaller children were trapped behind frantic students at the windows.
