IECEx
The objective of the IECEx System is to facilitate international trade in equipment and services for use in explosive atmospheres, while maintaining a required level of safety. 'Ex' areas can be known by different names such as 'Hazardous Locations', 'Hazardous Areas', 'Explosive Atmospheres', and relate to areas where flammable liquids, vapours, gases or combustible dusts are likely to occur in quantities sufficient to cause a fire or explosion. The modern day automation of industry has meant an increased need to use equipment in Ex areas. Such equipment is termed 'Ex equipment'.
