Range of application: On buildings for maintenance and cleaning work. For chimneys, specific regulations apply to the attachment and back protection.
Irrespective of the climbing height:
Either back protection or safety railing can be used as fall protection (combination not permitted as the rescue of persons is then hindered by the back protection)
The need for an occupational medical examination for suitability for working at height (e.g. G 41) depends on the risk assessment (e.g. total climbing height, type of safety railing) of the respective vertical ladder systems
Proof of the load-bearing capacity of the underlying surface must be provided for each construction project by a responsible stability expert
Barrier (safety door) is always required
The vertical overlap of successive ladder flights must be at least 1,680 mm
At unsecured exit levels, railings attached to both sides of the vertical ladder or led into the exit level are required
Gap at exit step must not be larger than 75 mm
Step-on dimension: Distance from the entry level to the first rung: 100 – 400 mm. If the exit is to the front, the uppermost rung must be at the same height as the exit level
Step-on dimension: Distance from entry level to the first rung 100–400 mm
When exiting forwards, the uppermost rung must be at the height of the exit side-rail
Vertical ladders with fall protection require at least 800 × 800 mm clear space available in front of the ladder when climbing off it. These dimensions must also be observed for new installations in the existing system
