Safety of machinery - Safety requirements for machinery and equipment for production of steel by electric arc furnaces

2Scope / Description

This European Standard specifies the general safety requirements for electric arc furnaces (EAF) to melt steel
not containing radioactive material.
This European Standard deals with all significant hazards, hazardous situations and events pertinent to EAF,
when used as intended and under conditions foreseen by the manufacturer, but also includes foreseeable
faults and malfunctions in case of misuse.
This European Standard specifies also criteria for the plant and equipment integrated in the production
process.
This European Standard specifies the requirements to ensure the safety of persons which are to be met
during the design, assembly, transport, commissioning, operation, maintenance and decommissioning of the
equipment.
This European Standard assumes that installations are operated and maintained by adequately trained and
competent personnel. Manual intervention for setting, adjustment and maintenance is accepted as part of the
normal use of the equipment.
This European Standard covers the following equipment (see Annex B):
? EAF with AC technology (alternating current);
? EAF with DC technology (direct current);
? scrap pre-heating technology;
? associated equipment/devices according Annex B.
The following equipment is not covered by this European Standard:
? induction furnace;
? resistance-arc furnace;
? electron beam furnace;
? plasma furnace;
? other electrical furnaces used in secondary steelmaking.
This European Standard does not specify safety requirements for the following equipment, which can be an
integral or complementary part of the equipment covered by the Scope:
a) cranes;
b) scrap basket;
c) transport car for scrap basket;
d) elephant house (furnace encasing for environmental reasons);
e) separate scrap drying equipment.
