BS EN IEC 60079-10-1:2021 PDF Download

BS EN IEC 60079-10-1:2021 is a revised standard that provides information on the classification of hazardous areas where explosive gas atmospheres may be present. It sets out criteria for assessing ignition hazards and offers guidance on design and control parameters to mitigate these hazards. The standard is intended for members of Hazardous Area Classification teams, as well as individuals with an understanding of flammable substances, gas dispersion, ventilation, and process aspects. It may also benefit other engineering disciplines and personnel responsible for safety.

The standard specifically addresses the classification of areas with flammable gas or vapor hazards, excluding certain scenarios such as mines susceptible to firedamp, explosives processing, catastrophic failures, medical rooms, domestic premises, and areas with combustible dust or flyings (though the principles can be used for assessing hybrid mixtures).

Using BS EN IEC 60079-10-1:2021 helps reduce the risk of explosions and supports the proper design, construction, operation, and maintenance of equipment for hazardous areas. It enhances expertise in hazardous area classification, improves risk management, and fosters trust in the safety of these areas. This third edition of the standard addresses concerns raised by the UK and includes technical changes such as the removal of safety factors and revisions to equations and charts.
