A stop control device shall be placed near each start control device. NOTE If the protective measure cannot easily be maintained in correct working order, this can encourage the defeat or circumvention of the protective measure in order to allow continued use of the machinery.
As necessary, anchorage points for personal protective equipment against falls from height shall also be provided for example, in carriers of machinery for lifting persons or with elevating control stations. A hazardous event can have different causes.
