Safety of machinery - Secondary steelmaking - Machinery and equipment for treatment of liquid steel
This European Standard specifies the general safety requirements for secondary steelmaking machinery and equipment (SSE) as defined in 3.1 to treat liquid steel.
This European Standard covers machinery and equipment involved in the treatment process of liquid steel under vacuum or atmospheric pressure.
This European Standard deals with all significant hazards, hazardous situations and events pertinent to SSE, 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 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 SSE 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.
NOTE 1 Annex B shows examples of SSE.
The following equipment is not covered by the scope of this European Standard:
- cranes;
- fork lift trucks or other transporting equipment;
- ladles;
- equipment for relining and preheating in the relining area;
- burners according EN 746-2;
- dust and fume exhaust systems.
NOTE 2 Significant hazards and hazardous situations due to transporting/positioning of heavy components, e. g., by cranes (e. g., ladles, vessels, covers) are considered in this standard (see 5.2.3).
This European Standard is not applicable to SSE manufactured before the date of publication of this standard in the Official Journal.

EN 14677:2008 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100. The machines and equipment concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provision of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. Where for clarity an example of a preventive measure is given in this European Standard, this should not been 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. 1 Scope This European Standard specifies the general safety requirements for secondary steelmaking machinery and equipment (SSE) as defined in 3.1 to treat liquid steel. This European Standard covers machinery and equipment involved in the treatment process of liquid steel under vacuum or atmospheric pressure. This European Standard deals with all significant hazards, hazardous situations and events pertinent to SSE, 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 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 SSE 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. NOTE 1 Annex B shows examples of SSE. The following equipment is not covered by the scope of this European Standard: cranes; fork lift trucks or other transporting equipment; ladles; equipment for relining and preheating in the relining area; burners according to EN 746-2; dust and fume exhaust systems. NOTE 2 Significant hazards and hazardous situations due to transporting/positioning of heavy components, e. g., by cranes (e. g., ladles, vessels, covers) are considered in this standard (see 5.2.3).
