Hazardous Area
Hazardous Area Mobile Phones — ATEX Zone 1, Zone 2, Zone 21 and Zone 22A hazardous area is any location where explosive atmospheres — formed by flammable gases, vapours, mists or combustible dusts mixed with air — are present or likely to occur. In these classified zones, all electrical equipment including mobile phones must be certified under ATEX (Europe) or ATEX (international) standards to prevent ignition. Infinity EX supplies a comprehensive range of hazardous area certified mobile phones, tablets and communication devices for Zone 1, Zone 2, Zone 21 and Zone 22 environments worldwide.Understanding Hazardous Area Zone ClassificationZone 0: Explosive gas atmosphere is present continuously or for long periods. Only Ex ia (Category 1G) apparatus is permitted.Zone 1: Explosive gas atmosphere is likely under normal operation. Ex ia or Ex ib (Category 1G/2G) apparatus is required.Zone 2: Explosive gas atmosphere may occur occasionally under abnormal conditions. Ex ic or higher (Category 2G/3G) apparatus is required.Zone 21: Combustible dust cloud likely under normal operation. Category 1D/2D apparatus required.Zone 22: Combustible dust cloud possible under abnormal conditions. Category 2D/3D apparatus required.Industries Operating Hazardous Areas
Oil and gas production, refining and distribution.Petrochemical and chemical manufacturing.Pharmaceutical solvent processing.Mining (underground gas hazards and surface dust hazards).Grain handling, flour mills and food processing (combustible dust).Paint and coatings manufacturing.LNG terminals, gas power stations and hydrogen facilities.Selecting the Right Device for Your Hazardous AreaThe correct device for a hazardous area is determined by the Zone classification of the area where it will be used, the gas group (IIA, IIB or IIC) and the temperature class (T1–T6). Infinity EX provides pre-sales technical support to help procurement and HSE teams select the appropriate certified device for their specific area classifications and project requirements.Frequently Asked QuestionsWhat is the difference between Zone 1 and Zone 2?Zone 1 is a location where an explosive gas-air mixture is likely to occur during normal operation. Zone 2 is a location where an explosive gas-air mixture is not likely to occur during normal operation but may occur in abnormal conditions. Zone 1 requires Category 1G or 2G ATEX apparatus. Zone 2 requires Category 2G or 3G apparatus. Equipment certified for Zone 1 is always acceptable in Zone 2, but not vice versa.Do I need ATEX certification for all electronics in a hazardous area?Yes. All electrical and electronic equipment that is taken into or permanently installed within a classified Zone 1 or Zone 2 area must carry ATEX certification appropriate to that zone. This includes mobile phones, radios, tablets, torches, gas detectors and any other battery-powered or mains-powered device. The only exceptions are equipment specifically excluded from the ATEX Directive scope, such as detonators.
