Full title and description

GOST R ISO 14122-3-2009 — Safety of machinery. Permanent means of access to machinery. Part 3: Stairs, stepladders and guard‑rails. This is the Russian adoption (GOST R) of the ISO technical specification covering non‑powered fixed means of access that are integral to machinery.

Abstract

This standard gives safety requirements for non‑powered stairs, stepladders and guard‑rails that form part of stationary (and where applicable mobile) machinery, including adjustable or movable non‑powered parts (for example foldable or slidable elements). It specifies minimum dimensions, protection measures (handrails, guard‑rails), slip resistance and load considerations needed to reduce fall and contact hazards associated with permanent means of access.

General information

• Status: Adopted national standard (GOST R) — published and in national use as of publication; users should verify current national status with Rosstandart or the relevant standards registry.
• Publication date: 1 July 2010 (designation shows 2009 in the standard number but the GOST R publication date is recorded as 01/07/2010).
• Publisher: National technical standards body of the Russian Federation (GOST R / Rosstandart) — Russian adoption of the ISO document.
• ICS / categories: 13.110 (Safety of machinery).
• Edition / version: GOST R ISO 14122-3-2009 — national adoption of ISO 14122‑3 (original international edition relates to ISO 14122‑3:2001; ISO issuance was later revised in 2016).
• Number of pages: 18 (as published in the GOST R document).

Scope

The standard applies to fixed, non‑powered stairs, stepladders and guard‑rails that are part of machinery and to non‑powered adjustable or removable means of access associated with machinery. It may also be applied to parts of a building serving primarily as access to the machine, and it is intended to be used together with ISO 14122‑1 (selection of means of access) and the other parts of the ISO 14122 series. Powered means of access (lifts, escalators) are excluded.

Key topics and requirements

• Definitions and classification of stairs, stepladders and guard‑rails as permanent means of access.
• Dimensional requirements for treads, risers, step depth, pitch angles and clearances to ensure safe ascent and descent.
• Handrail and guard‑rail design: heights, cross‑section, continuity and grip criteria to reduce fall hazards.
• Slip resistance, non‑entrapment features and avoidance of tripping edges.
• Structural strength and load‑bearing requirements for steps, landings and guard‑rails.
• Requirements for movable or adjustable non‑powered access elements (locking, retention, safe positions).
• Marking, instruction and information for safe use and maintenance where applicable.
• Integration with ISO 14122‑1 and other parts of the series for selection and overall access strategy.

Typical use and users

Used by machinery designers and manufacturers to design and validate permanent access elements; by safety and compliance engineers for risk reduction and conformity assessment; by maintenance and facilities personnel for safe installation and upkeep; and by certification bodies and regulators when assessing machine access safety. It is also referenced by architects or building engineers when building elements primarily serve machine access.

Related standards

ISO 14122 series (parts 1, 2, 3 and 4) — in particular ISO 14122‑1 (selection of means of access), ISO 14122‑2 (working platforms and walkways) and ISO 14122‑4 (fixed ladders). The GOST R adoption is a national implementation of the ISO document; the international ISO text was revised (ISO 14122‑3:2016) and users should consider the latest ISO edition or national updates when ensuring compliance. Other regional/adopted versions (EN ISO 14122‑3, national adoptions) provide compatible guidance.

FAQ

Q: What is this standard?

A: GOST R ISO 14122-3-2009 is the Russian national adoption of ISO 14122‑3, specifying safety requirements for non‑powered fixed means of access to machinery (stairs, stepladders and guard‑rails).

Q: What does it cover?

A: It covers dimensional, structural and protective requirements (handrails, guard‑rails, slip resistance, load capacity, and safe operation of adjustable non‑powered access elements) for permanent means of access that are part of a machine or, where applicable, part of the building serving machine access. Powered access systems are excluded.

Q: Who typically uses it?

A: Machinery designers, manufacturers, safety engineers, maintenance teams, conformity assessors and regulators — anyone responsible for designing, installing or assessing permanent access to machinery.

Q: Is it current or superseded?

A: The GOST R document was published as GOST R ISO 14122-3-2009 (published in the national registry on 1 July 2010). The underlying ISO standard (ISO 14122‑3) was revised internationally in 2016 (ISO 14122‑3:2016). Users should check the current status of the GOST R edition with Rosstandart and consider ISO 14122‑3:2016 for the most recent international requirements.

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO 14122 series (Permanent means of access to machinery). Parts 1, 2 and 4 cover selection of access, platforms/walkways and fixed ladders respectively; they are intended to be used together.

Q: What are the key keywords?

A: Safety of machinery, permanent access, stairs, stepladders, guard‑rails, handrails, tread/riser, slip resistance, load capacity, ISO 14122‑3, GOST R.
