ladder edge. To avoid danger and ensure safety, make sure that three parts of
the body should be kept on the ladder, that is, the feet should be pressed against
the ladder and one hand fast grips the ladder, as shown in Figure 4. Never climb
the topmost four rungs of a ladder. If one is about to climb to the roof, the length
