Full title and description

Safety of machinery — Risk assessment — Part 2: Practical guidance and examples of methods. This Technical Report gives practical guidance on conducting risk assessment for machinery in accordance with ISO 12100 and describes methods, tools and example risk‑reduction measures to support design, installation and modification of machinery.

Abstract

ISO/TR 14121-2:2012 (Edition 2) provides non‑normative, practical guidance for the steps of a machinery risk assessment process: hazard identification, risk estimation/evaluation, and selection of risk reduction measures. The report illustrates methods and tools, and includes worked examples to help designers, safety specialists and technicians apply ISO 12100 principles in a variety of machine contexts.

General information

Scope

Provides practical, non‑prescriptive guidance for performing risk assessments of machinery in line with ISO 12100: it describes methods and tools for each step of the process, gives examples of risk reduction measures, and supplies worked examples to illustrate application across a range of machinery types and complexity levels. The guidance is intended for use by designers, integrators, installers and safety specialists when assessing and reducing risks.

Key topics and requirements

• Practical guidance for hazard identification, risk estimation and risk evaluation aligned with ISO 12100.
• Overview of methods and tools (qualitative and semi‑quantitative approaches) usable at different stages of design and lifecycle.
• Examples of risk reduction measures and guidance on selection of protective solutions.
• Worked example(s) illustrating a complete risk assessment and risk reduction process (annexed example material).
• Non‑normative, informative content intended to support—but not replace—formal risk assessment procedures.

Typical use and users

Used by machine designers, safety engineers, risk assessors, maintenance planners, and technical personnel involved in design, installation, modification or review of machinery. Typical applications include design-stage assessments, machine safety audits, documentation of risk‑reduction decisions, and training or reference for applying ISO 12100 principles.

Related standards

ISO/TR 14121-2:2012 is intended to be used in conjunction with ISO 12100 (Safety of machinery — General principles for design — Risk assessment and risk reduction). It replaces the earlier ISO/TR 14121-2:2007 and is associated with other machine‑safety type A, B and C standards developed under ISO/TC 199.
