ISO 14122-4:2016 gives requirements for fixed ladders which are a part of a stationary machine, and to the non-powered adjustable parts (e.g. foldable, slidable) and movable parts of fixed ladder systems. NOTE 1 "Fixed" means of access are those mounted in such a manner (for example, by screws, nuts, welding) that they can only be removed by the use of tools. ISO 14122-4:2016 specifies minimum requirements that also apply when the same means of access is required as the part of the building or civil construction (e.g. fixed ladders) where the machine is installed, on condition that the main function of that part of the construction is to provide a means of access to the machine. NOTE 2 Where no local regulation or standards exists, this part of ISO 14122 may be used also for means of access which are outside the scope of the standard. It is intended that this part of ISO 14122 be used with ISO 14122‑1 to give the requirements for fixed ladder systems. The ISO 14122 series as a whole is applicable to both stationary and mobile machinery where fixed means of access are necessary. It is not applicable to powered means of access such as lifts, escalators, or other devices specially designed to lift persons between two levels. ISO 14122-4:2016 is not applicable to machinery manufactured before the date of its publication.
Abstract
Overview
EN ISO 14122-4:2016 - Safety of machinery: Permanent means of access to machinery - Part 4: Fixed ladders specifies minimum safety requirements for fixed ladders that form part of stationary machinery, including non‑powered adjustable (e.g. foldable, slidable) and movable parts of fixed ladder systems. “Fixed” means access mounted so it can only be removed using tools. The standard is intended to be used together with ISO 14122‑1 and the wider ISO 14122 series and supports conformity with EU Machinery Directive 2006/42/EC where applicable.
Key topics and technical requirements
- Scope and application: Applies to fixed ladders used as means of access to machinery and, where the primary function is machine access, to similar building-installed ladders. Not applicable to powered access (lifts, escalators) or to machinery manufactured before publication.
- Selection and design: Guidance on choosing ladder types based on space, expected use and interaction with obstacles; includes treatment of non‑powered adjustable or movable ladder parts.
- Fall protection: When fall protection is required; acceptable types (safety cages, fall arresters) and guidance for risk assessment. Special treatment for ladder systems above certain heights (e.g., >3 000 mm up to ≤10 000 mm, and >10 000 mm).
- Platforms and landings: Requirements for arrival/departure platforms, intermediate and rest platforms, and access openings/trap doors.
- Ladder configurations: Specific requirements for ladders with two stiles and for single‑stile ladders covering strength, rung design, and connections to guards.
- Loads and structural design: Consideration of permanent (dead) loads, variable (rated) loads and additional loads; design and verification of stability.
- Verification and testing: Methods for verifying strength and stability by calculation and testing, including tests for ladder elements and safety cages.
- Information for use: Requirements for instruction handbooks and user information needed for safe installation, inspection and maintenance.
Practical applications and users
EN ISO 14122-4:2016 is used by:
- Machine designers and OEMs specifying integrated fixed ladders
- Plant engineers, safety managers and maintenance teams assessing access safety
- Installers and fabricators of fixed ladder systems and safety cages
- Compliance officers and auditors demonstrating conformity with safety legislation (e.g., Machinery Directive)
- Procurement specialists specifying safe access equipment
Typical applications include industrial plants, processing machinery, machine enclosures and any stationary or movable machinery requiring permanent, non‑powered access.
Related standards

- ISO 14122 series (overall framework for permanent means of access)
- EU Machinery Directive 2006/42/EC - Annex ZA links this standard to essential requirements for conformity
