NOTE Consultation of the user on this subject is often necessary. These principles and methods shall be applied singly or in combination as appropriate to the circumstances see ISO and IEC Iteration of this process can be necessary to eliminate hazards as far as practicable and to adequately reduce risks by eh implementation of protective measures.

It is assumed that, when present on machinery, a hazard will sooner or later lead to harm if no protective measure or measures have been implemented. Physical aspects c d 6. For cycle initiation by a sensitive protective equipment, only active opto-electronic protective devices Be complying with IEC series shall be used, provided that: NOTE 3 The terms for types of guards are defined in 3.

Yes No — — fixed guards see 6. While automatic feeding and removal devices have much to offer in preventing accidents to machine operators, they can create danger when any faults are being corrected.
