The first step to a safe machine is establishing the limits of the machine and in particular its application as directed. This includes, for example, its application area, operating modes, service life and the interface between people and machine.
Using these specifications, you can identify points of danger and evaluate the risk of each individual danger. If it turns out that the risk would be too great without implementing additional measures, then the said risk must be reduced to an acceptable level.
The measures taken should prevent the danger entirely or reduce it by using an inherently safe design. Only if these measures do not lead to sufficient reduction of the risk should you rely on technical protective measures and – as a last resort – the documentation.
