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 part of EN ISO 14122, see clause 4.
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. "
NOTE 2 The use of materials other than metals (wood composite materials, so-called "advanced" materials, etc.) does not
alter the application of this part of EN ISO 14122.
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 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
