by endorsement, at the latest by November 2001, and conflicting national standards shall be withdrawn at the latest
by November 2001.
This European Standard has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following

Introduction
EN ISO 14122 consists of the following parts, under the general title "Safety of machinery - Permanent means of
access to machinery" :
Part 1 : Choice of a fixed means of access between two levels
Part 2 : Working platforms and walkways
Part 3 : Stairs, stepladders and guard-rails
Part 4 : Fixed ladders.
This part of EN ISO 14122 is a type B standard as stated in EN 1070.
This document is to be read in conjunction with clause 1.6.2 "Access to operating position and servicing points"
and 1.5.15 "Risk of slipping, tripping or falling" of the essential safety requirements expressed in annex A of
EN 292-2:1991/A1:1995. See also 6.2.4 "Provision for safe access to machinery" of EN 292-2:1991.
For the significant hazards covered by this standard, see clause 4 of EN ISO 14122-1.
The provisions of this document may be supplemented or modified by a type C standard.
NOTE 1 For machines which are covered by the scope of a type C standard and which have been designed and built
according to the provisions of that standard, the provisions of that type C standard take precedence over the provisions of this
type B standard.
The dimensions specified are consistent with established ergonomic data given in EN 547-3 "Safety of machinery - Human body
dimensions – Part 3 : Anthropometric data".
NOTE 2 The use of materials other than metals (composite materials, so-called "advanced" materials, etc.) does not alter the
application of the present standard.
Annexes A and ZA are for information only.
This part of EN ISO 14122 contains a Bibliography.

1 Scope
EN ISO 14122 defines the general requirements for safe access to machines mentioned in EN 292-2. Part 1 of EN
ISO 14122 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 working platforms and walkways which are a part of a machine.
This part of EN ISO 14122 may also apply to working platforms and walkways 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.
NOTE This part of EN ISO 14122 may be used also for means of access which are outside the scope of this standard. In
those cases the possible relevant national or other regulations should be taken into account.
This part of EN ISO 14122 applies also to working platforms and walkways 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.
