Safety of machinery. Permanent means of access to machinery – Fixed ladders

This part of ISO 14122 gives requirements for fixed ladders which are a part of a stationary machine, and to the non-powered adjustable parts (e.g. foldable, slidable) and movable parts of fixed ladder systems.
“Fixed” means of access are those mounted in such a manner (for example, by screws, nuts, welding) that they can only be removed by the use of tools.
This part of ISO 14122 specifies minimum requirements that also apply when the same means of access is required as the part of the building or civil construction (e.g. fixed ladders) where the machine is installed, on condition that the main function of that part of the construction is to provide a means of access to the machine.
Where no local regulation or standards exists, this part of ISO 14122 may be used also for means of access which are outside the scope of the standard.
It is intended that this part of ISO 14122 be used with ISO 14122‑1 to give the requirements for fixed ladder systems.
The ISO 14122 series as a whole is applicable to both stationary and mobile machinery where fixed means of access are necessary. It is not applicable to powered means of access such as lifts, escalators, or other devices specially designed to lift persons between two levels.
This part of ISO 14122 is not applicable to machinery manufactured before the date of its publication.
