Foreword

This British Standard has been prepared by Subcommittee B/208/1. It supersedes BS 4211:1994, which is withdrawn.

This edition represents a full revision of the 1994 edition, to align the requirements with those currently used in the access industry and to adopt, where appropriate, the requirements of BS EN ISO 14122. The revision has included the removal of class A and class B designations of ladders.

BS 4211:2005+A1:2008 supersedes BS 4211:2005, which is withdrawn.

This British Standard forms one of a group of standards covering permanent fittings to give access to high structures including high buildings and chimneys, and plant. Others in the group are as follows.

BS 3572, Specification for access fittings for chimneys and other high structures in concrete or brickwork.

BS 3678, Specification for access hooks for chimneys and other high structures in steel.

BS 5395‑3, Stairs and ladders and walkways — Part 3: Code of practice for the design of industrial type stairs, permanent ladders and walkways.

BS EN ISO 14122, Safety of machinery — Permanent means of access to machinery, particularly Part 4: Fixed ladders (2005).

For portable ladders in aluminium and timber, attention is drawn to BS 2037 and BS 1129 respectively.
