Risk reduction

Minimizing risks and selecting suitable protective measures are not part of the risk assessment
Fig. 1-1 Iterative process to achieve safety in compliance with ISO 14121 (EN 1050)
Risks must be reduced by suitably designing and implementing the machine. For
instance a control system or protective measures suitable for the safety-related
functions.
If the protective measures involve interlocking or control functions, then these must
be designed and implemented acc. to EN 954/ISO 13849. For electrical and elec-
tronic controls, EN 62061 can be used as an alternative to EN 954/ISO 13849.
Electronic controls and bus systems must also comply with IEC/EN 61508.
