Safety of machinery – Prevention of unexpected start-up
This standard specifies built-in safety measures aimed at preventing unexpected machine start-up (see 3.2) to allow safe human interventions in danger zones (see Annex A).
This standard applies to unexpected start-up from all types of energy source, i.e.:
– Power supply, e.g. electrical, hydraulic, pneumatic;
– Stored energy due to, e.g., gravity, compressed springs;
– External influences, e.g. from wind.
