What is IEC 60079-61:2014?

IEC 60079-61:2014 is an international standard that provides guidelines for the design, installation, and maintenance of electrical installations in hazardous areas. Hazardous areas are those environments where there is a risk of explosion due to the presence of flammable gases, vapors, or combustible dusts. This standard focuses on the requirements for the selection, installation, inspection, and maintenance of electrical equipment used in these hazardous areas.

Scope and Application

The scope of IEC 60079-61:2014 includes all aspects of electrical installations in hazardous areas. It covers both fixed and portable equipment, including cables, connectors, control devices, and lighting fixtures. The standard applies to installations in various industries, such as oil and gas, chemical manufacturing, mining, and pharmaceuticals. It is essential for ensuring the safety of personnel, property, and the environment in these hazardous locations.

Main Requirements

IEC 60079-61:2014 outlines several key requirements that must be met for electrical installations in hazardous areas. One of the main requirements is the classification of hazardous areas based on the presence and nature of potential explosive atmospheres. This classification helps in determining the appropriate electrical equipment and protection techniques required for each location.

The standard also provides guidelines for proper equipment selection, taking into consideration factors such as temperature, vapour pressure, and the presence of corrosive substances. Additionally, it specifies requirements for installation practices, wiring methods, grounding, and bonding to ensure the integrity of the electrical system and prevent any potential sources of ignition.

Maintenance and Inspection

IEC 60079-61:2014 emphasizes the importance of regular maintenance and inspection of electrical installations in hazardous areas. This includes routine checks, testing, and preventive measures to ensure that the equipment remains in a safe operating condition. The standard provides guidance on inspection intervals, procedures for visual and detailed inspections, and record keeping.

Moreover, it highlights the significance of personnel competency and training to carry out these maintenance and inspection activities effectively. It stresses the need for individuals involved in working with electrical equipment in hazardous locations to receive proper training and certification.

In conclusion, IEC 60079-61:2014 is a crucial international standard that sets forth requirements and guidelines for electrical installations in hazardous areas. Compliance with this standard ensures the safety of individuals, protects property, and minimizes the risk of explosions caused by electrical equipment in potentially explosive atmospheres. Adhering to these guidelines reduces the chances of accidents and incidents, making hazardous environments safer for everyone involved.
