Overview

EN 16774:2016 - published by CEN - is a type C European standard titled Safety of machinery - Safety requirements for steel converter and associated equipment. It specifies safety requirements for a steel converter and its associated equipment (the converter plant) used in carbon and stainless steelmaking by the oxygen process. The standard addresses significant hazards, foreseeable misuse and the full lifecycle: transport, assembly, commissioning, operation, maintenance (see Clause 5), and decommissioning/disassembly.

Key scope items include charging (hot metal/liquid steel and scrap), oxygen refining and stirring, temperature measurement and sampling, tapping (including slag retaining devices), cooling systems, maintenance devices (e.g. relining, tap hole repair), and process interfaces with media, gas cleaning plant, material feeding and ladle systems. It is not applicable to converter plants manufactured before publication in the Official Journal; it can be used as a guideline for revamping.

Key Topics and Requirements

• Hazard identification and risk reduction: lists of significant hazards, hazardous situations and safety measures (see Clause 4 and Clause 5).
• Lifecycle safety: rules for safe transport, assembly, commissioning, operation, maintenance and decommissioning.
• Control systems and electrical safety: special requirements for safety-related control systems and shut-down equipment are given in Annex A.
• Operator information and signage: requirements for warnings, markings, documentation and personnel training are covered in Clause 7 (7.1–7.5).
• Verification and testing: procedures to verify safety requirements and measures are described (Clause 6).
• Noise: measurement, declaration and verification of noise emission values and test-code guidance are provided in Annex C.
• Exclusions and limits: does not cover use of process media other than oxygen, nitrogen, argon and compressed air, nor certain plant components (e.g. primary/secondary gas cleaning, radioactive measuring devices, auxiliary hoists).

Practical Applications and Users

Who uses EN 16774:2016:

• Machine and plant manufacturers designing steel converters and associated equipment.
• Plant owners/operators implementing safe operating procedures and controls for oxygen steelmaking.
• Maintenance and service providers performing relining, tap hole repair and commissioning.
• Safety engineers and compliance teams performing risk assessments and preparing technical documentation aligned with the Machinery Directive (see Annex ZA).
• Regulators and certification bodies assessing conformity with European safety requirements.

Practical benefits:

• Reduces occupational hazards in converter plants (explosions, burns, crushing, noise exposure).
• Provides structured requirements for control systems, emergency stop, signage and training.
• Supports conformity assessment and safer revamping of existing equipment.

Related Standards

EN 16774:2016 is intended to be used in conjunction with general machinery safety standards such as EN ISO 12100 (risk assessment), EN ISO 13849 / EN 62061 (functional safety), EN 60204-1 (electrical equipment) and relevant ergonomic, noise and guarding standards listed in Clause 2 and the normative references.
