Annex A gives examples of methods for several steps of the risk assessment process; and Annex B contains an example application of the process of risk assessment and reduction.

Most of the examples conclude with a discussion of the method and its suitability for different types of machinery.

Clause 7 covers Risk assessment iteration and Clause 8 covers documentation. Hazard identification by application of forms Risk matrices Risk graphs Numerical scoring Quantified risk estimation Hybrids This last example is a hybrid method of numerical scoring and a risk matrix.

Jon Severn, the editor of MachineBuilding. It therefore contains numerous cross-references to Part 1; for example, readers are referred to Part 1 for all terms and definitions bar one. Given the title of this Technical Report, readers may be pleasantly surprised to learn that it includes risk reduction as well as risk assessment.

This Clause is effectively a detailed explanation of the risk assessment process shown in Figure 1 of ISOexcept for a few steps – such as determination of the limits of the machinery, and hazard identification – where readers are referred back to ISO Although it is described as ‘non-exhaustive’ it nevertheless contains considerable detail. Clause 5 – Risk assessment process This Clause is effectively a detailed explanation of the risk assessment process shown in Figure 1 of ISOexcept for a few steps – such as determination of the limits of the machinery, and hazard identification – where readers are referred back to ISO In all six examples, considerable detail is provided, including graphs and tables where appropriate.
