SIST EN ISO 14122-1:2016 PDF

Overview

EN ISO 14122-1:2016 - Safety of machinery - Permanent means of access to machinery - Part 1: Choice of fixed means and general requirements of access (ISO 14122-1:2016) provides general requirements and guidance for selecting and designing permanent means of access to stationary machines. It covers fixed access components (including non‑powered adjustable or movable parts such as foldable or slidable elements) that are part of the machine or, where the primary function is machine access, part of the building. This part is intended to be used together with access‑specific parts of the ISO 14122 series (Parts 2–4).

Key topics and technical requirements

• Scope and applicability
  • Applies to permanent, fixed means of access to stationary machinery (not to powered lifts, escalators or devices designed to lift people).
  • Not applicable to machines manufactured before publication date.
• Terms, definitions and significant hazards
  • Identifies hazards related to slipping, tripping and falling, and access to operating and service points.
• General design and construction requirements
  • Minimum requirements for safe access layout and integration with machines or structures.
• Selection of fixed means of access
  • Guidance on choosing the preferred access type (ramps, stairs, walkways, platforms, stepladders, fixed ladders) based on conditions, frequency of use and safety.
  • Criteria for when stepladders or fixed ladders are acceptable.
  • Guidance for choosing between ramps and stairs, and between stepladders and fixed ladders.
• Information for use
  • Requirements for instruction handbooks and warnings to inform safe operation and maintenance.
• Normative and informative annexes
  • Includes examples to improve access through machine or system changes and notes on technical changes from prior editions.

Practical applications

• Use EN ISO 14122-1:2016 when designing, installing or assessing fixed access to machinery: working platforms, walkways, stairs, ladders and guard-rails that are part of the machine or provided primarily for machine access.
• Useful during machine design reviews, risk assessments, factory layout planning and compliance checks.
• Supports conformity to EU machinery Directive (Directive 2006/42/EC) when used with the relevant access-specific parts, offering a presumption of conformity for hazards such as slipping, tripping and falling.

Who should use this standard

• Machine manufacturers (design and build safe permanent access)
• Health & safety professionals and regulators (risk assessment and compliance)
• Plant engineers and maintenance teams (access design for serviceability and safe maintenance)
• Standards bodies and consultants developing type-C standards or machine‑specific guidance

Related standards

• ISO 14122 series: Part 2 (working platforms & walkways), Part 3 (stairs, stepladders & guard‑rails), Part 4 (fixed ladders).
• Refer to Directive 2006/42/EC for regulatory context and conformity assessment.
