BS EN ISO 14122-3:2001+A1:2010

Applies to fixed and removable stairs, stepladders and guard-rails for stationary and mobile machinery, including those in that part of the building where the machine is installed.

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 stairs, step ladders and guard-rails which are a part of a machine.

This part of EN ISO 14122 may also apply to stairs, step ladders and guard-rails 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 1 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.

NOTE 2 For mobile machinery, alternative requirements can apply due to their dimensions and particular conditions of use.

This part of EN ISO 14122 applies also to stairs, step ladders and guard-rails 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).
