The standard provides precise ergonomic and structural specifications to minimize risks of slipping, tripping, or falling in industrial environments. 1. Stairs and Stepladders Access systems are categorized by their : Stairs : Angle of pitch between 20∘20 raised to the composed with power 45∘45 raised to the composed with power Stepladders : Angle of pitch between 45∘45 raised to the composed with power 75∘75 raised to the composed with power Geometric Standards for Stairs: din en iso 14122-3 pdf

Stepladders are defined as access devices with a steeper incline than stairs.
Stairs are recommended when the angle of climb is between 30° and 45°. When working with a digital PDF version of
Using standard step rise of 200 mm: 3000 mm / 200 mm = 15 steps. Number of risers = 15. Number of treads = 14 (one less for top floor landing).
The "going" (the horizontal distance between the noses of two consecutive steps) must be between 210 mm and 310 mm. Steps: Steps must be non-slip to prevent falls. 2.3 Stepladders
This standard does not apply to public stairways, escalators, or construction site scaffolding. It is strictly for permanent access to machinery . Stairs are recommended when the angle of climb
Available through local national standards institutions (e.g., DIN, BSI, AFNOR).
DIN EN ISO 14122-3 does not exist in isolation. It is Part 3 of a four-part series:
Industrial machinery and plants require safe access for operators and maintenance personnel. DIN EN ISO 14122-3 is the harmonized international standard that dictates the design, dimensions, and safety requirements for stairs, stepladders, and guard-rails.
In conclusion, DIN EN ISO 14122-3 is an important standard that specifies the safety requirements for energy-absorbing devices used in personal fall arrest systems. The standard helps to ensure that these devices are designed and manufactured to provide effective protection against falls from a height, and compliance with the standard is essential for organizations that use these devices.
