Is it still necessary to wear a speed differential anti fall device with an enclosure structure

Nowadays, there is a risk of falling from heights above 2 meters when engaging in high-altitude operations, and it has become a consensus in the industry that speed difference fall arresters must be worn. However, some high-altitude work sites are different from conventional high-altitude work sites, as they have relatively solid safety maintenance structures around and under their feet. The only difference is that the workers stand at a relatively high height. Do high-altitude operations such as working inside the enclosure structure need to wear fall arresters?

If working in low wind conditions, there is still no risk. If a tornado suddenly occurs, it is likely to blow people down from high altitude. In short, although there is a protective structure, it cannot guarantee the safety of workers 100%.

In fact, as long as one wants to protect their life safety in high altitude, they must comply with the safety regulations for high-altitude operations. There is no room for negotiation on this, after all, in the face of disasters, any language will become pale and powerless, and it is a self deception and sophistry.

When working in a high-altitude work space with a protective structure, the speed differential anti fall device can be hung on a relatively fixed hanging point, such as thin and easily breakable steel structural plates, which are not suitable as hanging points.
