AS 1657 – Fixed platforms, walkways, stairways and ladders – Design, construction and installation

AS 1657 sets out requirements for the design, selection, construction and installation of fixed platforms, walkways, stairways and ladders that are intended to provide safe access to places used by operating, inspection, maintenance and servicing personnel.

This Standard also applies to the following:

(a) Movable platforms that are permanently configured but that may be site adjustable or site assembled/modified.
(b) Permanently installed roof access, where such access is for the purpose of installing, operating, inspecting, maintaining or servicing equipment that is located on, or is accessible from, the roof.
(c) Permanently installed access for inspection and maintenance of the roof itself.

NOTES:

1 In the absence of a directly applicable Standard, this Standard may be used for guidance in providing access to some parts of stationery and mobile machinery, light and telecommunication towers, wind turbine towers and water and sewerage facilities. While such access may not be capable of conforming to all the requirements of this Standard, the principles and imposed actions should be followed.
2 Appendix A provides information on recommended component dimensions and materials for edge protection.
3 Appendix F provides a method for testing the load-carrying capacity of a twin-stile or single-stile fixed ladder.
4 Appendix G provides information on selection of stairways, walkways and fixed ladders.
5 Appendix H provides guidelines for fall protection measures for various types of ladders.
6 Appendix I provides design, fabrication and installation considerations for ladders to improve their safety and reduce the likelihood of injury to users.
7 Appendix J provides guidelines for roof access for the purposes of routine equipment or building maintenance activities.
