This International Standard specifies basic terminology, principles and a methodology for achieving safety in
the design of machinery. It specifies principles of risk assessment and risk reduction to help designers in
achieving this objective. These principles are based on knowledge and experience of the design, use,
incidents, accidents and risks associated with machinery. Procedures are described for identifying hazards
and estimating and evaluating risks during relevant phases of the machine life cycle, and for the elimination of
hazards or the provision of sufficient risk reduction. Guidance is given on the documentation and verification of
the risk assessment and risk reduction process.
This International Standard is also intended to be used as a basis for the preparation of type-B or type-C
safety standards.
It does not deal with risk and/or damage to domestic animals, property or the environment.
NOTE 1 Annex B gives, in separate tables, examples of hazards, hazardous situations and hazardous events, in order
to clarify these concepts and assist the designer in the process of hazard identification.
NOTE 2 The practical use of a number of methods for each stage of risk assessment is described in ISO/TR 14121-2.
