A.1 Standards and regulations
The risk assessment is a procedure that allows hazards resulting from machines to be
systematically investigated. Where necessary, the risk assessment is followed by a risk
reduction procedure. When the procedure is repeated, this is known as an iterative process.
This can help eliminate hazards (as far as this is possible) and can act as a basis for
implementing suitable protective measures.
The risk assessment involves the following:
● Risk analysis
● Risk assessment (EN ISO 14121-1 Paragraph 8)
As part of the iterative process to achieve the required level of safety, a risk assessment is
carried out after the risk estimation. A decision must be made here as to whether the
residual risk needs to be reduced. If the risk is to be further reduced, suitable protective
measures must be selected and applied. The risk assessment must then be repeated.
