The application of ignition risk management for electrical equipment/apparatus, is handled relatively well by the industry. However, there is still much confusion on how to identify, manage and document non-electrical risks.

With the introduction of ISO/IEC 80079 -36, -37, -38 and the subsequent harmonisation under ATEX Directive (2014/34/EU), clarity on the requirements has led to many issues being highlighted when assessing equipment.  This is not through the introduction of new sources of ignition but rather that the identification and understanding of the hazards from non-electrical equipment/apparatus more widely visible.

For example, now that IEC TS 60079-46 has become mandatory (since 1st Jan 2020) it is highlighting issues with “assemblies” as this expects non-electrical equipment/apparatus to be certified.

We will look briefly into the history and how potential ignition risks have “traditionally” been understood with respect to equipment/systems currently/commonly in use. 

We will also investigate the main non-electrical ignition risks and some common applications or considerations we see causing confusion with products going to market.
