Guardrails are mandatory on any open side where a fall height exceeds 500 mm. Key requirements:
Indispensable for machinery safety compliance, but budget time to digest it – and keep Parts 1 & 4 handy.
When spatial constraints make standard stairs impossible, stepladders fill the gap. The standard defines stepladders as having an angle of inclination between . Because of the steep pitch, operators must face the ladder when descending. Angle of Inclination: 45° to 75°. Rise ( ): 220 mm minimum to 250 mm maximum. Going ( ): At least 80 mm deep for adequate foot placement. Clear Width ( ): Between 450 mm and 600 mm. Maximum Flight Height ( ): A single flight cannot exceed 3000 mm without a landing. 5.

Stepladders are utilized when space constraints prohibit standard stairs. They operate at a steeper pitch, typically between 45° and 75°.

The primary objective of this standard is to prevent workers from falling or tripping when accessing machinery. It harmonizes European (EN) and international (ISO) specifications. This provides a unified framework for manufacturers, safety officers, and structural engineers worldwide. The Four Parts of the ISO 14122 Series Choice of fixed means of access between two levels. Part 2: Working platforms and walkways. Part 3: Stairs, stepladders, and guardrails. Part 4: Fixed ladders. Scope and Field of Application
The standard is copyrighted. To get a legitimate copy: The standard defines stepladders as having an angle
Preferred for frequent access between levels with an angle between 20° and 45°.
The standard dictates precise dimensions, load capacities, and structural designs to eliminate geometric hazards. Below are the core engineering requirements outlined in the regulation. 1. Guard-rails (Handrails and Balustrades)
