Fall arresters cannot be used in case of strong wind

There are many windy weather in northern China. When the wind force is greater than level 4, trees, towers, roofs and other things will be affected by the wind. At this time, even if the staff carrying out high-altitude work projects wear high-altitude fall arresters, they can not continue to engage in high-altitude work projects.

Once, when two construction workers were cleaning the outer wall glass of the high-rise hotel outdoors, a strong wind suddenly blew. The strong wind caused the safety ropes of the two people's fall arresters to wind together, and neither of them could rise or fall. At this time, there was no fixed force point, so they could only stay on the outer wall, Then the hotel staff rescued them after more than an hour of continuous rescue work.

Therefore, in case of windy weather, high-altitude workers should fall to the ground in time. In addition, in addition to windy weather, high-altitude fall arresters cannot be used in bad weather such as rainstorm, thunder and fog, so as to avoid personal accidents during operation.
