The Explanation For Ex / Hazardous Location Areas

- Nov 20, 2019-

Ex areas can be known by different names such as “Hazardous Locations”, “Hazardous Areas” “Explosive Atmospheres”, and the like and relate to areas where flammable liquids, vapors, gases or combustible dusts are likely to occur in quantities sufficient to cause a fire or explosion. For safty, more and more harsh places are equipted with led explosion proof light.

 

Products  designed and developed to  be installed and used in hazardous areas must be certified in  accordance with project and regional requirements. The standards for hazardous areas are not the same for all regions.


An 'explosive atmosphere' is a mixture with air, under atmospheric conditions, of flammable substances in the fom
of gases, vapours, mists or dusts in which, after ignition has occurred, combustion spreads to the entire unburned
mixture. The ATEX directive does not define atmospheric conditions, but normally a temperature range of ‐20 oC to+60 oC and a pressure range of between 0.8 and 1.1 bar is accepted.
