Q/CSG510001-2015, electric safety working procedure of south Power grid Limited liability company, china, 20.2.3, states that when working on scaffolds without railings, the height exceeds 1.5m, safety belts should be used or other reliable safety measures should be taken. 20.2.2 specifies that the harness should be high-hanging and low-hanging, and should not be hung on moving, sharp or loose objects. The protection of the safety belt should not be lost when climbing the tower and transferring the position. In the operation process, whether the safety belt is fastened should be checked at any time. Similar regulations, there are specific requirements in the regulations issued by the country.
According to the above regulation, when an operator climbs the cat ladder, in order to prevent falling, personal safety is guaranteed, the operator can wear the safety belt, protection is realized through alternate use of the surrounding rod belt and the two protection ropes, each upper lattice can be stopped, the upper safety belt is well beaten, the lower safety belt is taken down, and the repeated operation is carried out continuously, so that much physical strength and energy of the operator are consumed.
Under the condition, if the operator saves time and accelerates the speed, the situation that the hanging is low and the use is high or the surrounding rod belt and the two protective ropes are not straightened and the protection is not in place can occur, and once the foot is lost, the impact on the safety belt and the operator is very large.
