What is IEC 60079-22:2014?

IEC 60079-22:2014 is an international standard that provides guidelines for designing, installing, and maintaining electrical equipment in hazardous areas. These hazardous areas include locations where flammable gases, vapors, or dust particles exist, such as oil refineries, chemical plants, and mines.

The Importance of IEC 60079-22:2014

This standard outlines essential safety measures to prevent explosions and protect the lives of workers in hazardous environments. It sets out requirements for electrical equipment, including wiring systems, motors, lighting fixtures, and control devices, to ensure their integrity in potentially explosive atmospheres.

By following the guidelines of IEC 60079-22:2014, organizations can enhance workplace safety, reduce the risk of accidents, and comply with regulatory requirements. Adhering to this standard also helps prevent costly equipment failures that could result in downtime and production losses.

Main Provisions of IEC 60079-22:2014

The standard covers various aspects related to electrical equipment in hazardous areas, including:

Classification of hazardous areas: The standard defines different zones based on the likelihood of the presence of flammable substances. This classification helps determine the appropriate level of protection required for electrical equipment.

Selection and installation of equipment: IEC 60079-22:2014 specifies criteria for selecting and installing electrical equipment in hazardous areas, taking into consideration factors such as temperature, humidity, and the properties of the surrounding atmosphere.

Maintenance and inspection: The standard emphasizes the importance of regular maintenance, inspection, and testing of electrical equipment to ensure its ongoing suitability for use in hazardous areas.

Training and competency: It is crucial for personnel working with electrical equipment in hazardous areas to possess the necessary skills and knowledge. IEC 60079-22:2014 provides guidance on training requirements and competency assessments.


IEC 60079-22:2014 plays a vital role in ensuring the safety of electrical equipment in hazardous areas. By following its provisions, organizations can mitigate the risk of explosions, protect workers' lives, and comply with regulatory standards. Investing in proper equipment selection, installation, and maintenance not only enhances workplace safety but also contributes to the smooth operation of facilities in hazardous environments.
