DIN EN ISO 14122-3:2016-10 (the latest version) specifies requirements for non-powered stairs, step ladders, and guardrails that provide safe access to machinery. It applies to permanent access routes where the vertical rise exceeds 500 mm or where there is a risk of falling.
The standard is part of a five-part series:
Part 3 is unique because it bridges the gap between vertical ladders (Part 4) and horizontal walkways (Part 2). It covers inclined access systems with steps—ideal for frequent use or when carrying loads. din en iso 14122-3 pdf
DIN EN ISO 14122-3 does not exist in isolation. It is Part 3 of a four-part series:
This standard is part of the ISO 14122 series, which deals with the safety of machinery access. Specifically, Part 3 defines the safety requirements for the design and construction of stairs, stepladders, and guard-rails that are permanently attached to machinery. DIN EN ISO 14122-3:2016-10 (the latest version) specifies
Its primary goal is to provide safe access for operators and maintenance personnel to parts of the machinery that are at height (above floor level). It helps manufacturers and engineers comply with the EU Machinery Directive (2006/42/EC) regarding fall protection and ergonomic access.
In the realm of machinery safety, the focus is often on guarding moving parts or emergency stop mechanisms. However, a significant portion of industrial accidents occurs not during the operation of the machine, but while accessing it for maintenance, cleaning, or adjustment. This is where DIN EN ISO 14122-3 plays a critical role. Part 3 is unique because it bridges the
This standard is the definitive guideline for designing safe stairways, stepladders, and guard-rails for machinery. This article explores the scope of the standard, key design requirements, and how accessing the PDF version is essential for compliance.
