1 Scope
This European Standard defines the general safety requirements for hot rolling mills
for long products as defined in 3.1.
This European Standard deals with significant hazards, hazardous situations and events
relevant to hot rolling mills for long products. It deals not only with circumstances where the machinery is used as intended, but
also includes other conditions foreseen by the manufacturer, such as foreseeable faults,
malfunctions or misuse (see Clauses 4 and 5).
This applies also to hazards arising during various phases of the life of the machinery
and equipment as described in 5.4 of EN ISO 12100:2010.
This European standard applies to: Machinery and equipment used for the manufacturing of metal rolled long products from the material supply from (1), via the rolling mill process equipment (2) to
(9) including preparation area (10) (exemplary layout is given in Figure 1).
