Energy and networks

There are two types of metal structures: permanent installations (antennas, pylons, etc.) and temporary installations (stages, tents, etc.). Techniques for movement depend directly on the characteristics of the structure (shape, condition, etc.) and on the presence or absence of protective devices.

Most of the time, whether they are temporary or permanent, these structures are not equipped with collective protection. The worker at height must therefore ensure his own safety with individual protection. This is the case, for example, when working on an antenna or when setting up or taking down structures for events.

To protect himself in the case of a fall, the worker at height must use a fall arrest system (self-belay on the structure with an energy-absorbing lanyard or on a lifeline with a mobile fall arrester). To do this, a lifeline must first be installed. If necessary, a positioning system is used to allow for hands-free work. If the structure is equipped with collective protection (safety nets, etc.), the worker can use a work positioning system (adjustable lanyard).

In special cases, the worker may also need to use advanced techniques for progression (alpine technique for lifeline installation when it has not been pre-installed on the structure, hauling system for lifting loads, descending on a rope, etc.).
