A: Angle. Stairs are 30°–45°; stepladders are 45°–75°. Stepladders allow steeper access where space is limited but have stricter tread design rules.
The standard does not apply to powered means of access such as lifts, escalators, or any other devices designed to lift people between two levels. din en iso 14122-3 pdf
Preferred for frequent access between levels with an angle between 20° and 45°. A: Angle
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 standard does not apply to powered means
The document sets out specific technical parameters to minimize the risk of falling, slipping, and overexertion. The key sections include:
