France: infrastructure
Nuclear power produces around 70% of France's electricity from 56 active reactors in 2023, so large plant outages bring many contractors to a small number of sites.

More about France that matters for portable equipment
France: logistics and access
Le Havre is France's second-largest commercial port by tonnage and its largest for containers, managed since 2008 by the state agency Grand Port Maritime du Havre, a key entry point for imported equipment.
France: infrastructure
Hydropower has 20 GW of installed capacity and supplies around 10% of French electricity, and renewables provided 26% of national consumption in 2022.
France: background
The Lacq gas field in Nouvelle-Aquitaine was discovered in 1950 and began production in 1958; its sour gas comes from about 4,000 metres depth.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In France. In France the phrase explosion-proof covers several concepts. Flameproof Ex d suits some heavy equipment, whereas an intrinsically safe handset limits energy at source. For refinery units, LNG terminals at Montoir and Fos, and hydrogen networks, the IS-04Z1 is designed around intrinsic safety rather than a heavy flameproof enclosure.

Specifying an explosion proof mobile phone for France
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · France
Frequently asked questions
Can we buy an explosion proof mobile phone in France today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an explosion proof mobile phone in France cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which sites in France does this cover?
The market guide for France covers Gonfreville-l'Orcher, Port-Jérôme, Donges, Montoir-de-Bretagne, among others. Site-level pages are linked below.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Where in France is hazardous-area work concentrated?
The Fos-sur-Mer and Marseille coast combines a gas terminal, steel, chemistry and oil industries, and the country also has many nuclear and hydro sites. Details of individual plants and zones come from each operator, so request their site layout and approval procedure.
Does France apply ATEX to handheld devices in hazardous areas?
Yes, as an EU member France applies ATEX Directive 2014/34/EU to equipment and zoning under Directive 1999/92/EC. Zone 1 or Zone 2 devices should carry CE and Ex markings with instructions in French. Operators usually add their own approval and permit rules.
Is a French-language interface available?
Android lets the interface language be set per user, and a fleet can be managed through EMM or MDM. Confirm the exact language support and any locked configuration on the datasheet. Contractor crews often prefer a common set-up agreed before a shutdown.
