Industrial furnaces and related process equipment Electric arc furnace steelmaking machinery
and equipment safety requirements
1 Scope
This document specifies general safety requirements for electric arc furnace (EAF) steelmaking without radioactive material.
Note. Radioactive substances are tested before entering the steel plant.
This document addresses the significant hazards, hazardous situations and hazardous events listed in Table 1 associated with EAF, when
When used under long-term conditions, it also includes foreseeable failures and failures during misuse.
This document specifies guidelines for the integration of equipment and equipment in the production process.
This document specifies the requirements for the safety of personnel during the design, transport, assembly, commissioning, operation, maintenance and decommissioning of equipment.
This document assumes that the equipment is operated and maintained by adequately trained personnel, with manual setup, adjustment and maintenance as part of the normal use of the equipment.
