The following applies irrespective of the height at which the person is climbing:;As fall protection, back protection is preferable to fall arresters (combination not permitted, as the rescue of persons is hindered by the back protection).Occupational health examination for fitness for work at heights (e.g. G 41), the necessity of which depends on the risk assessment (e.g. total height, height of the person, etc.). The necessity depends on the risk assessment (e.g. total height, type of fall protection) of the respective fixed ladder system; proof of the load-bearing capacity of the subsoil must be provided for each construction project by a responsible expert for stability.If the access situation requires it, suitable safety devices (e.g. steel end caps) must be installed on ladders with climbing protection. If the access situation requires it, suitable protective devices (e.g. steel end stops) must be provided to prevent unauthorised use.For side accesses, the ladder sections must be led higher;In the case of ladders with several sections, the overlap of the rear guard must be at least 2.000 mm.At unsecured exit points, guardrails must be fitted on both sides of the ladder or led into the exit level.The gap at the exit must not exceed 60��75 mm: Distance from entry level to first rung 100 � 400 mm. The top edge of the top rung must be at the same height as the running surface of the exit point.The gap between the ladder system and the guardrail must not exceed 120 mm. The connection to the climbing protection must be made and released from a secure location. A secure location is, for example, a platform with railings and secure access; a safety bar, order no. 063502, is required at the exit. This is not included in the scope of delivery of the complete set and must be ordered separately;The maximum height of the individual ladder sections is 6.0 m.
