Workstations for work at height must be accessible in complete safety. The most appropriate means of access to these workstations is chosen taking into account the frequency of traffic, the height to be reached and the duration of use. This means of access must be ergonomically appropriate and enable any person in difficulty to be rescued quickly and evacuated in the event of imminent danger.
It must be possible to move around at height safely. Passage, in either direction, between a means of access and platforms, floors or gangways must not create a risk of falling.
