Safety belt is a protective equipment to prevent high-altitude operators from falling. Because the higher the falling height, the greater the impact force. Therefore, the safety belt must have the following two basic conditions: (1) it must have sufficient strength to bear the impact force when the human body falls; (2) It can prevent the human body from falling to a certain limit that can cause injury (that is, it should be able to pick up the human body before this limit and stop falling). This condition needs to be explained again that when the human body falls down from a height, if it exceeds a certain limit, even if the human body is pulled by the safety belt, it will also cause internal organs injury and death due to too much impact. Therefore, the length of the safety belt should not be too long, and there should be a certain limit.
