The International Electrotechnical Commission (IEC) has published a new technical specification: IEC 60079-32-1 “Explosive atmospheres – Part 32-1: Electrostatic hazards – Guidance”, a guidance document within IEC 60079 “Explosive atmospheres”. The standard has been developed to prevent fire spread and explosions caused by electrical faults.
The standard has been divided into seven sections
– Handling of solid materials
– Storage and handling of liquids
– Handling of gases and vapours
– Storage and handling of powders
– Storage and handling of explosive materials
– Avoiding electrostatic discharges
– Grounding and bonding of machinery
It constitutes the most comprehensive guidance produced to date and represents a coherent, global approach to controlling electrostatic risks in workplaces. Further information regarding materials, processes/equipment that may be affected by electrostatic discharges and how they can be minimised is clearly described in the specification.
