Web2 SYSTEMATIC APPROACH TO THE ASSESSMENT OF ELECTROSTATIC IGNITION HAZARDS For every assessment of an electrostatic ignition hazard the scheme shown in Figure 1 is extremely helpful. In all cases where a fire or explosion in industrial environments is caused by static electricity, the sequence of events passes through the same stages. WebSince 2016, it is also possible to perform evaluation and certification under the IECEx Scheme, with the recent ExMC 15 decision and publication of the ISO/EN 80079-36 and 80079-37 standards. The Ignition Hazard Assessment covers Normal Operation as well as Expected Malfunction and Rare Malfunction.
