This part of EN ISO 14122 defines the general requirements for safe access to machines mentioned in EN 292-2. It gives advice about the correct choice of access means when the necessary access to the machine is not possible directly from the ground level or from a floor. This part of EN ISO 14122 applies to all machinery (stationary and mobile) where fixed means of access are necessary. This part of EN ISO 14122 applies to means of access which are a part of a machine. This part of EN ISO 14122 may also apply to means of access to that part of the building (e.g. working platforms, walkways, ladders) where the machine is installed, providing the main function of that part of the building is to provide a means of access to the machine. NOTE This part of EN ISO 14122 may be used also for means of access which are outside the scope of this part of EN ISO 14122. In those cases the possible relevant national or other regulations should be taken into account. This part of EN ISO 14122 applies also to access means specific to the machine which are not permanently fixed to the machine and which may be removed or moved to the side for some operations of the machine (e.g. changing tools in a large press). This part of EN ISO 14122 does not apply to lifts, to moveable elevating platforms or other devices specially designed to lift persons between two levels
