Introduction
This document is a type C standard as stated in EN ISO 12100:2010.
This document is not applicable to finishing lines for metal strip (according to the scope) manufactured
before the date of its publication.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
Where for clarity an example of a preventative measure is given, this should not be considered as the only
possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent
level of safety is achieved.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine and/or plant manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine and/or plant users/employers (small, medium and large enterprises);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.

This document (prEN 17449:2019) has been prepared by Technical Committee CEN/TC 322 “Equipment
for making and shaping of metals”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.

Introduction
This European Standard is a type C standard as stated in EN ISO 12100:2010.
This document is not applicable to finishing lines for metal strip (according to the scope) manufactured
before the date of its publication.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
Where for clarity an example of a preventative measure is given, this should not be considered as the only
possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent
level of safety is achieved.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine and/or plant manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine and/or plant users/employers (small, medium and large enterprises);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.

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).
Key
1 supply or removal of material (as coil) or tools (e.g. spool/sleeve)
2 finishing process (e.g. cutting, trimming, punching, straightening, laminating, inspecting, rewinding)
3 removal or supply of material (e.g. as coil, slit strip, stack) respectively pallet feed
4 changing devices (e.g. levelling rolls, knife shaft, cutting tools)
5 border of the finishing line
