fire fighting is a serious matter. knowing what to do during a fire can save people's lives. it is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency（紧急事件）exits, but not lifts. from the lower floors of buildings, escaping through windows is possible. learn the best way to get out from a window with the least chance of serious injury. the second floor window is usually not very high from the ground. an average（普通的）person, hanging by the fingertips（手指尖）will have a drop of about 6 feet to the ground. it is about the height of an average man. of course, it is safer to jump a short way down than to stay in a burning building. windows are also useful when you are waiting for help. be sure to keep the door closed before opening the window. otherwise, smoke and fire may be drawn into the room. keep your head low at the window to be sure
