Karl Metcalfe, Technical Support for the The Association of Electrical and Mechanical Trades (AEMT), looks at the knowledge and responsibilities that are expected when managing electric motors in zoned areas.

Potentially explosive atmospheres are encountered in many industrial sectors. Specific areas that may be affected are zoned according to the potential risks, and any electrical equipment in these areas must be designed and manufactured to specific standards.

International standards

Any business that has identified zoned areas within its processes is expected to adhere to several international and regional standards, including BS EN IEC 60079-10:2019. This states the responsibilities of operators, managers and repairers to ensure that all equipment is fit for continued service.

Equipment that is designed for Ex zoned areas uses a variety of protection concepts to ensure safe operation. Different concepts can be used in similarly zoned areas, and it is important that site maintenance engineers understand them so that they do not compromise the equipment.
