- 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. ISO 14122-1:2016 is not applicable to machinery manufactured before.

The ISO 14122 series as a whole is applicable to both stationary and mobile machinery where fixed means of access are necessary.
EN ISO 14122-4: Safety of machinery - Permanent means of access to machinery - Part 4: Fixed ladders
The Standard EN ISO 14122-4 was published in Italy on October 2016, replaces the previous EN ISO 14122-4 of 2010 and is not applicable to machinery manufactured before the date of its publication.
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.
The new standard, thanks to the use of images, allows to have a clearer idea of what are the requirements to be observed.
The new approach of EN 14122-4: 2016
While the previous EN 14122-4 shows a list of all the dimensions to be respected, the approach adopted by the new standard is to provide a guide for choosing the main features and the elements that the ladders will have.
Guidelines are given for the choice of the type of ladder based on the available space and defining the spaces to be respected between the various elements of the ladder and any other fixed obstacle present in the area.

Guidelines are given for the choice of the type of ladder based on the available space and defining the spaces to be respected between the various elements of the ladder and any other fixed obstacle present in the area.
A guide is also given to the choice of personal protective equipment against falls from a height and for the assessment of risks related to the ladder, taking into account aspects such as effort, damage due to falling, frequency of use, etc.
Based on the total height, the new standard establishes which dimensions to comply with and which protection devices to adopt. It also establishes how rest platforms should be placed.
NB: The structures such as buildings and machine parts, may constitute a safety cage in themselves, provided that the dimensions obtained are the same as those established by the standard for the construction of safety cages.
Physical characteristics of the ladder and protection devices
The standard details the test to be performed, both with one or two stiles.
The test weights and the application points are established for the various elements of the ladder (rungs and stiles) and for any protection devices (safety cages or guard-rails).
The geometric features (design and construction) of all the elements that can form the ladder system, from rungs to safety cages, are detailed. This section specifies that the fall protection devices to be applied to the arrival area are independent of any other protection device applied to the ladder. Therefore, it is not possible to avoid other fall protection devices just because, for example, it is expected to use the fall arrester along the ladder.
Marking of Ladeder systems with fall arrester
At least the following shall be permanently marked at point of entry and exit to the ladder system:
