Overview

Standard Reference: EN 15949:2012
Title: Safety of machinery - Safety requirements for bar mills, structural steel mills and wire rod mills (hot rolling mills for long products)
Organization: CEN

EN 15949:2012 defines general safety requirements for hot rolling mills that produce long products (bar mills, structural steel mills and wire rod mills). The standard addresses significant hazards, hazardous situations and events during normal use and foreseeable faults, malfunctions or misuse (see Clauses 4 and 5). It covers hazards across the life phases of the machinery (per EN ISO 12100:2010) and applies to equipment from material supply through rolling, preparation and downstream handling. Certain equipment (e.g., furnaces, continuous casting machines, hook conveyors, roll shop tools, storage systems and vehicles) are explicitly excluded.

Key Topics

• Risk assessment & design planning: General requirements for design, planning of long-product rolling mills and structural assembly.
• Access and guarding: Safe access to work places and danger zones, guards, guard-rails and safeguarding measures.
• Control systems & stop functions: Normative Annex A covers control-system safety, selection of stop and emergency-stop functions and shut‑down equipment.
• Mechanical and process safety: Safety requirements for roller tables, conveyors, rolling stands, rolling blocks, cross transfers, cutting machines, cooling lines and other process equipment.
• Fluid and pneumatic systems: Normative Annex B addresses hazards and safety measures for fluid systems.
• Noise and vibration: Annex C provides a noise test code and measurement/declaration guidance. Vibration and ergonomics requirements are included.
• Fire and gas safety: Fire protection, and Annex D on protection against asphyxiant gases used in fire-fighting systems.
• Verification & information for use: Procedures for verification of safety measures, marking, instruction handbooks and maintenance manuals.
• Maintenance guidance: Informative Annex E gives example safety instructions for maintenance and safe work procedures.

Applications

EN 15949:2012 is practical for:

• Machine builders and OEMs designing or delivering bar, structural steel and wire rod rolling mills.
• Plant designers and integrators implementing safe layouts, guarding and control systems.
• Safety engineers and risk assessors conducting risk assessments and compliance checks.
• Maintenance teams and operators using the standard’s guidance for safe servicing, signage and operating modes.
• Notified bodies and certifiers verifying conformity with European machine safety requirements.

Using EN 15949:2012 helps reduce mechanical, thermal, noise and fluid-related hazards in hot rolling mills and supports compliance with European machinery safety practice.
