scope:

This Standard: - specifies the general safety requirements for secondary steelmaking machinery and equipment (SSME) as defined in 3.1 to treat liquid steel. - deals with all significant hazards, hazardous situations and events pertinent to SSME, when used as intended and under conditions foreseen by the manufacturer, but also includes foreseeable misuse, faults and malfunctions. - specifies the requirements to ensure the safety of persons which are to be met during the design, pre-assembly, transport, sites assembly, commissioning, operation, maintenance, decommissioning and dismantling/ disassembling of the equipment. - assumes that SSME 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 Standard applies to SSME involved in the treatment process of liquid steel under vacuum or atmospheric pressure and covers: - LF, Ladle furnace, - VD, Vacuum degassing, - VOD, Vacuum oxygen decarburization, - RH (OB), Ruhrstahl Heraeus (oxygen blowing), - process related interfaces/interactions (e.g. according to design, controls) to o process media, o primary and secondary gas cleaning plant, o material handling systems, o transfer cars for steel ladle, and o crane and ladle.
