ANSI/ISA-60079-10-1 (12.24.01)-2014, Explosive Atmospheres – Part 10-1: Classification of areas – Explosive gas atmospheres, provides a systematic approach to identifying and classifying areas where explosive gas atmospheres may occur. This standard outlines how to assess the presence, frequency and extent of flammable gases or vapors based on factors like release rates, ventilation and equipment operation. It guides users in determining hazardous zones (Zone 0, Zone 1, Zone 2) to support safe selection and installation of electrical equipment in these environments. It also includes practical examples, calculation methods and documentation practices to help manage risks associated with explosive atmospheres in various industries.
