DIN EN ISO 14122-2:2016-10

Planning and implementing safe working platforms and walkways on machinery

DIN EN ISO 14122-2 specifies requirements for working platforms and walkways as permanent means of access to machinery. It helps manufacturers, designers, and operators design safe access for the operation, maintenance, servicing, and inspection of machinery. The standard is part of the DIN EN ISO 14122 series and provides more specific requirements relating to Machinery Directive 2006/42/EC.

What is DIN EN ISO 14122-2 about?

The standard defines requirements for the design and construction of working platforms and walkways that provide safe access to machinery. It focuses on clearance profiles, headroom, walkway widths, slip resistance, guardrails, toe plates, and fall protection. It also describes requirements for loads, movable working platforms, and the ergonomic design of permanent means of access.

Topics covered

• Working platforms and walkways on machinery
• Clearance profiles, headroom, and walkway widths
• Flooring and slip resistance
• Guardrails, toe plates, and fall protection
• Openings in working platforms and walkways
• Loads and load-bearing capacity requirements
• Movable working platforms and walkways
• Ergonomic requirements for means of access
• Information for use and safety requirements

Practical relevance

Safe access to machinery is essential for operation, maintenance, and servicing. DIN EN ISO 14122-2 helps companies design working platforms and walkways in compliance with the standard and reduce accident risks caused by falls, trips, or slips.

The requirements for slip resistance, fall protection, load-bearing capacity, and ergonomic design are especially relevant because they directly affect occupational safety and compliance with legal requirements. The standard is frequently used in conjunction with ISO 12100, ISO 13857, and other parts of the DIN EN ISO 14122 series.

Changes compared with DIN EN ISO 14122-2:2002-01 and DIN EN ISO 14122-2/A1:2010-12

The 2016 edition was comprehensively revised. The most important changes include:

• Extension of the scope to movable working platforms and walkways
• Introduction of new terms such as toe plate, skirting board, clearance profile, movable walkway, and movable platform
• New requirements for clear widths and headroom
• Expanded specifications for flooring, openings, and slip resistance
• Addition of requirements for movable working platforms and walkways
• Revision of the information for use and safety requirements

Target audience

• Machinery manufacturers
• Design engineers and development engineers
• Machinery safety specialists
• Safety engineers
• Operators of machinery and industrial installations
• Maintenance and servicing personnel
• Inspection bodies and experts
• Specialist planners for industrial installations

Conclusion

DIN EN ISO 14122-2 provides the key basis for the safe design of working platforms and walkways on machinery. With its requirements for geometry, slip resistance, fall protection, and information for use, it supports the standards-compliant implementation of safe means of access and makes a significant contribution to occupational safety around machinery.
