Safety of machinery - Permanent means of access to machinery - Part 4 : fixed ladders

ISO 14122-4:2004 applies to all machinery (stationary and mobile) where fixed means of access are necessary.The purpose of the standard is to define the general requirements for safe access to machines mentioned in ISO 12100-2. ISO 14122-1 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.The standard applies to fixed ladders which are a part of a machine.It may also be applied to ladders fixed to that part of the building 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.It also applies to ladders which are not permanently fixed to the machine and which may be removed, moved to the side or pivoted (swivel-mounted) for some operations of the machine (e.g. changing tools in a large press).

Safety of machinery - Permanent means of access to machinery - Part 4 : fixed ladders

ISO 14122-4:2004 applies to all machinery (stationary and mobile) where fixed means of access are necessary.

The purpose of the standard is to define the general requirements for safe access to machines mentioned in ISO 12100-2. ISO 14122-1 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.

The standard applies to fixed ladders which are a part of a machine.

It may also be applied to ladders fixed to that part of the building 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.

It also applies to ladders which are not permanently fixed to the machine and which may be removed, moved to the side or pivoted (swivel-mounted) for some operations of the machine (e.g. changing tools in a large press).

Safety of machinery - Permanent means of access to machinery - Part 4 : fixed ladders

ISO 14122-4:2016 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. NOTE 1 "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. ISO 14122-4:2016 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. NOTE 2 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. ISO 14122-4:2016 is not applicable to machinery manufactured before the date of its publication.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
