The clear width of the staircase should ideally be a minimum of 800 mm, though 1000 mm is preferred for two-way traffic or handling tools. 3. Stepladders
The recommended angle of inclination for industrial stairs is between . The maximum allowable angle under this standard is 45° . din en iso 14122-3 pdf
DIN EN ISO 14122-3:2016 establishes mandatory safety requirements for permanent industrial stairways, stepladders, and guard-rails, focusing on dimensions for safe access and fall protection, including specific structural load tests. The 2016 standard mandates a minimum guard-rail height of 1,100mm and outlines specific deflection limits under load.

The standard is part of a five-part series: When searching for a , be extremely careful
Where the guardrail opens to grant access to a ladder or stair, a self-closing swing gate must be installed. Gravity gates or drop bars are acceptable, provided they close automatically. Chains are strictly prohibited as a primary means of fall protection. 6. Structural Integrity and Load Testing
Guardrails are structural barriers designed to prevent accidental falls from heights of 500 mm or more. DIN EN ISO 14122-3 lays out precise dimensional envelopes for these safety structures. The 2016 standard mandates a minimum guard-rail height
A: Not directly, but it is a harmonized standard under the EU Machinery Directive. Following it gives a "presumption of conformity". Deviating is possible but you must prove equivalent safety.
When space restrictions make a standard stair impossible, engineers use stepladders. These operate at steeper angles and require different safety parameters. Typically ranges between 45° and 75° . Rise ( ): Ranges between 210 mm and 250 mm. Tread Depth ( ): Must be at least 80 mm to provide adequate foot support.
It covers both permanent, fixed structures and adjustable/movable parts. 2. Key Requirements of DIN EN ISO 14122-3
The current version of this standard is , which was last reviewed and confirmed in 2021. It replaces previous editions, such as the 2001 version, and is harmonized with European directives like the Machinery Directive 2006/42/EC .
