Full title and description

AS 1657:2018 — Fixed platforms, walkways, stairways and ladders — Design, construction and installation. This Australian Standard specifies technical requirements for the design, selection, construction and installation of fixed means of access used by operating, inspection, maintenance and servicing personnel, including permanently installed roof access and permanently configured movable platforms.

Abstract

AS 1657:2018 provides mandatory and advisory requirements for safe fixed access (platforms, walkways, stairways and ladders) with guidance on loads, geometry, slip resistance, edge protection, handrails, toeboards, testing and documentation. The Standard is intended to reduce fall and dropped-object hazards where personnel work at or move between different levels.

Scope

Specifies requirements for the design, selection, construction and installation of fixed platforms, walkways, stairways and ladders intended to provide safe access for operating, inspection, maintenance and servicing personnel. The Standard also applies to permanently configured movable platforms and permanently installed roof access for equipment inspection, maintenance and servicing. It may be used as guidance where no directly applicable standard exists for specific plant or tower access.

Key topics and requirements

• Means of access: selecting appropriate access type (walkway, stair, ladder) and allowable slope ranges.
• Design and fabrication: design loads, deflection limits, materials, corrosion protection and welding/fixings requirements.
• Platforms and landings: widths, headroom, slopes, slip resistance and drop-object protection (15 mm ball test for some floorings).
• Walkways: slope, minimum clear width, walking surface and cleat requirements, guardrailing and toeboards.
• Edge protection: guardrail design, posts, infill and testing/verification methods.
• Access between levels: stairway geometry (treads, risers, nosings, landings), fixed ladders (rung/stile types), cages, and fall-protection allowances.
• Testing and verification: test methods for guardrails, stair assemblies, ladder stiles and rungs and reporting requirements.
• Appendices with selection guidance, fall-protection guidance, ladder design details and roof-access recommendations.

Typical use and users

Used by designers, structural and mechanical engineers, fabricators, safety officers, asset owners, building services contractors and maintenance teams working on industrial plants, treatment works, commercial roofs, towers, utilities infrastructure and similar facilities where safe permanent access is required. It is commonly applied on projects to specify compliant platforms, walkways, stairways and fixed ladders.

Related standards

Commonly referenced and complementary standards include earlier versions of AS 1657 (2013, 1992), AS/NZS and machine-access standards such as the ISO 14122 series (safety of machinery — permanent means of access), and relevant structural, welding and building standards for materials and loads. AS 1657:2018 supersedes AS 1657-2013 (including its 2016 amendment).

FAQ

Q: What is this standard?

A: AS 1657:2018 is the Australian Standard that sets out design, construction and installation requirements for fixed platforms, walkways, stairways and ladders used as permanent means of access for personnel.

Q: What does it cover?

A: It covers selection of access type, geometry (widths, slopes, headroom), materials, loading and deflection criteria, slip resistance, edge protection (guardrails, infill, toeboards), stair and ladder design details, testing methods and documentation, plus guidance appendices (fall protection, ladder design, roof access).

Q: Who typically uses it?

A: Designers, engineers, fabricators, safety and maintenance personnel, asset owners and building/plant operators who specify, install or inspect permanent access systems in industrial, commercial and utility environments.

Q: Is it current or superseded?

A: AS 1657:2018 is the current edition (published April 2018) and supersedes AS 1657-2013 (and its 2016 amendment). Users should confirm any regional amendments or later revisions before application.

Q: Is it part of a series?

A: AS 1657 is a standalone standard focused on fixed access but is used alongside other standards (for example ISO 14122 series for machinery access, structural design standards, welding and materials standards) to provide a complete specification for access systems.

Q: What are the key keywords?

A: Platforms, walkways, stairways, ladders, guardrails, toeboards, slip resistance, fall protection, access design, fixed access, Standards Australia.
