Can the speed differential anti fall device and seat belt be hung at the same point

In high-altitude work, the probability of falling accidents is very high. Once falling from a high altitude, especially from a height of more than 10 meters, the pain and mortality rate caused to the human body is almost 100%. If speed difference fall arresters and safety belts can be worn during the work process, the mortality rate will decrease from over 90% to 1%.

There are many high-altitude workers required in engineering and power maintenance operations, and their working heights are not the same. Therefore, some workers may wear speed differential fall arresters, while others may wear safety belts. And the suspension points of the protective equipment they use are also on a crossbeam or a suspension point. So is this suspension method correct?

Firstly, we need to clarify that in the process of high-altitude operations, both speed differential anti fall devices and safety belts are indispensable. In fact, this suspension method is not right or wrong. The important thing is to check whether the load-bearing capacity, stability performance, and the sum of the weight of the workers' bodies of the suspension point match. If they do not match, even if high-altitude workers wear fall arresters and safety belts, their safety cannot be truly guaranteed. If they match, these two different protective devices can be suspended on the same suspension point at the same time.
