Effective ignition source is a term defined in the European ATEX directive as an event which, in combination with sufficient oxygen and fuel (gas, vapour, dust or fibres), can cause an explosion. Methane, hydrogen or coal dust are examples of possible fuels. Effective ignition sources are: Lightning strikes. Open flames.
European ATEX Directives There are two European Directives relating to potentially explosible atmospheres: ⚫ATEX 100a Equipment Directive (94/9/EC) - Due to be replaced soon with a new number. No changes to Essential Health and Safety Requirements of the Directive. Changes affect Notified Bodies rather than manufacturers.

(for example, matches and lighters) and the risks from electrostatic discharges. An international standard, BS EN 60079/10, explains the basic principles of area classification for gases and vapours, and its equivalent for dusts was published in 2002as BS EN 61241/3. These standards form a suitable basis

A4 Basics of Explosion Protection INTRODUCTION HAZARDOUS LOCATIONS INNOVATIVE EXPLOSION PROTECTION by R. STAHL 1-800-782-4357 TEMPERATURE CLASSES Ignition temperature or auto-ignition temperature (ATI) is the minimum temperature of a surface at which an explosive atmosphere ignites.
MIE typically range from 1 mJ to 1000 mJ [Janes]. The lower the MIE, the higher is the risk of explosion as a very small energy input can trigger a dust cloud explosion. MIE < 3 mJ should be processed with specific measures, the dust is extremely sensitive to ignition. Some equipment suppliers even refuse to handle projects with such low MIE as ...
example, a draft of air swirls up a layer of dust in a small area, the dust, along with oxygen, forms a combustible dust/air mix. If this mix is ignited by an ignition source, an explosion is triggered. The force of the resulting explosion swirls up more dust, which is in turn ignited. This process con-tinues, and under some conditions chain
The ATEX standard also has a classification for explosive gases and dusts, with Group I referring to methane gases and coal dust (mining), while Group IIA to IIC gases and Group IIIA and IIIC dusts (above ground industries) have been categorised according to their different igniting power, with IIA/IIIA being
IEC 60079 Design and Manufacture.
