This document specifies the general safety requirements for finishing lines for metal strip, hereafter referred as finishing line(s), as defined in 3.1. This document deals with significant hazards, hazardous situations and events relevant for finishing lines when used as intended and under conditions foreseen by the manufacturer. This document provides the requirements to be met by the manufacturer to ensure the safety of persons and property during transport, commissioning, operation and de-commissioning, as well as in the event of foreseeable failures or malfunctions that can occur in the equipment (see Clauses 4 and 5). This document is applicable to: Plant (machinery, equipment, devices) for the customer-specific processing of metal strip/metal foil (starting material: hot rolled or cold rolled strip as coil) from the material feeding (1) via the finishing process (2) until the material removal (3) (see exemplary layout in Figure 1). Examples of finishing lines and their machinery/equipment covered by the scope of this document are listed below: — finishing lines, e.g.: — slitting line (see Figure 2); — cut-to-length line (see Figure 3); — feeding line (see Figure 4); — blanking line; — trimming line; — rounding machines; — strip edge machining lines; — inspection lines; — rewinding lines, separator lines, doubler lines; — strip-supply lines (e.g. for presses or roll forming lines); — interlinked machinery/equipment which can be part of a finishing line, e.g.: — coil conveying (e.g. feeding in, threading, pushing-in, guiding and transporting); — stretching, bending, levelling machine; — marking machine; — recoiler and uncoiler; — shears; — punching machine; — coil and sleeve handling device; — welding machine; — oiling machine; — scrap chopper, scrap coiler, scrap conveyor; — changing device; — stacking device; — coil transport device (associated with the line); — measuring systems and devices; — fluid systems. The following machinery may be part of or linked to a finishing line but are not covered by this document: — packaging lines (EN 415); — roll forming lines; — machines for painting and laminating; — embossing machine; — saws; — plate shear (plate as raw material) (EN 13985); — equipment for applying (removing) media to (from) the material surface; — coil transport devices outside the boundaries of the line (e.g. supply from the storage); — presses (EN ISO 16092-1, EN ISO 16092-2 and EN ISO 16092-3); — milling machines (EN ISO 16090-1); — machinery using laser (EN ISO 11553) for strip processing (e.g. welding, cutting); — punching machines (as stand-alone machine); — cranes; — robots (EN ISO 10218); — separate media systems (e.g. compressed air system, exhaust system); — storage equipment. For modernization, this document can be applied for the parts to be modernized.
