Overview
EN 746-4:2000 (CEN) specifies particular safety requirements for hot dip galvanising thermoprocessing equipment used in industrial furnaces. This part of the EN 746 series covers the specific hazards and safety measures that the manufacturer must provide for both industrial batch hot-dip galvanising units and the baths of continuous galvanising lines, whether supplied as independent equipment or as integrated plant components. The standard focuses on safety of the thermoprocessing equipment itself and explicitly excludes handling, storage, transport, disposal, transfer or regeneration of zinc and processed materials outside the equipment limits, and does not address risks from separate component handling equipment or their protective measures.
Key Topics
The standard addresses manufacturer responsibilities and defines safety-related aspects for hot dip galvanising equipment. Key topics typically emphasized include:
- Identification of specific hazards related to hot dip galvanising equipment (for example: high temperatures, molten zinc contact, fumes and thermal risks).
- Design and construction safety requirements that manufacturers must integrate into batch and continuous galvanising baths.
- Control and protective measures to reduce operator risk and prevent equipment-related incidents.
- Information and documentation that manufacturers must supply (e.g., installation, operation and maintenance guidance, safety data).
- Scope and exclusions, clarifying that external zinc handling, storage, transport and disposal are outside the standard’s remit.
(EN 746-4:2000 provides the framework; consult the full standard for precise technical clauses and mandatory requirements.)
Applications
This CEN standard is directly applicable to:
- Manufacturers and suppliers of hot dip galvanising furnaces and baths (batch and continuous).
- Plant designers and integrators incorporating galvanising thermoprocessing equipment into production lines.
- Safety engineers, compliance officers, and procurement teams assessing equipment for industrial galvanising plants.
- Maintenance and operations teams seeking manufacturer-supplied safety documentation and procedures.
Using EN 746-4 helps ensure that galvanising equipment meets recognized safety requirements, reduces plant risk, and supports compliance with broader machinery and workplace safety regulations.
