Intrinsically Safe Cell Phone — ATEX Zone 1 and Zone 2 Certified
An
intrinsically safe cell phone is a mobile device engineered and certified to operate safely in Zone 1 and Zone 2 classified explosive atmospheres. Intrinsic safety (Ex ia / Ex ib) is the primary protection concept used in modern ATEX mobile phones — limiting the electrical energy within the device at component level so no spark, arc or surface temperature capable of igniting a flammable gas or vapour mixture can be generated. Infinity EX supplies intrinsically safe cell phones with full ATEX certification for global industrial use.How Intrinsic Safety WorksUnlike explosion-proof enclosures (Ex d) which contain a potential internal explosion, intrinsic safety prevents ignition at source. Every battery, circuit board, antenna connector and USB interface within an intrinsically safe cell phone is designed and tested to ensure its electrical parameters remain below the minimum ignition energy of any target gas group. This is verified against IEC 60079-11(intrinsic safety) andIEC 60079-0(general requirements) by an accredited Notified Body before the ATEX certificate is issued.ApplicationsOil & Gas Production:Offshore platforms, wellsites, pipelines and compressor stations.Refineries:Process units, tankage areas and loading facilities.Chemical Plants:Classified process areas with solvent, solvent vapour and flammable gas hazards.Mining:Gassy underground workings and surface processing plants.LNG & Gas Processing:Storage tanks, regasification terminals and dispatch facilities.Pharmaceuticals:Solvent-based manufacturing rooms classified Zone 1 or Zone 2.Compliance StandardsATEX Directive 2014/34/EU — Category 1G (Zone 1) or Category 2G (Zone 2).ATEX Scheme — internationally recognised for global project specifications.IEC 60079-0 and IEC 60079-11 — the specific technical standards for intrinsic safety.IP68 — fully sealed against fine dust and continuous water submersion.Frequently Asked QuestionsWhat is an intrinsically safe cell phone?An intrinsically safe cell phone is a mobile device certified under the Ex ia or Ex ib protection concept. Its internal electrical energy is limited by design so it cannot produce a spark or surface temperature capable of igniting any flammable gas or vapour mixture in a classified Zone 1 or Zone 2 area. The intrinsic safety certification is issued by an accredited ATEX Notified Body following independent testing against IEC 60079-11.Can I charge an intrinsically safe phone inside a hazardous zone?This depends on the specific device certification and whether the charger is also zone-rated. In most cases, intrinsically safe phones must be charged outside of classified zones unless a specifically certified charging solution is used. Always refer to the conditions of safe use (CoSU) document supplied with the device for guidance on charging within classified areas.
