This document deals with requirements for machine design, transport, installation, commissioning, operation, adjustment, maintenance and cleaning to minimize the hazards listed in Annex F. These hazards can arise during the operation and maintenance of continuous handling equipment and systems when carried out in accordance with the specifications given by the manufacturer or his authorized representative. This document deals with safety related technical verification during commissioning. This document applies to mechanical handling devices as defined in Clause 3, singly or combined to form a conveyor system, and designed exclusively for moving unit loads continuously on a predefined route from the loading to the unloading points, possibly with varying speed or cyclically. In general, it also applies to conveyors which are built into machines or attached to machines if not stated otherwise in a machine specific standard. Safety requirements and/or measures in this document apply to equipment used in all environments. However, additional risk assessments and safety measures need to be considered for uses in severe conditions, e.g. – freezer applications, – high temperatures, – corrosive environments, – strong magnetic fields, – potentially explosive atmospheres, – radioactive conditions and loads the nature of which could lead to a dangerous situation (e.g. molten metal, acids/bases, especially brittle loads, explosives), – operation on ships and earthquake effects and – contact with foodstuff. This document does not cover hazards during decommissioning. This document does not apply to conveying equipment and systems used underground or in public areas and to aircraft ground support equipment. In public areas only baggage carousels and check-in conveyors for airports are dealt with in this document. NOTE Aircraft ground support equipment is covered by the standards of CEN/TC 274. This document is not applicable to continuous handling equipment and systems manufactured before the date of its publication.
