Switzerland: projects and investment
The Mantelerlass, passed on 29 September 2023, sets a target of 35 TWh a year from new renewable technologies by 2035, compared with about 6 TWh a year in 2022, which implies major construction work.
The IS-04Z1 is an intrinsically safe Android handset designed for solvent and powder atmospheres, from a production building in Basel or Visp to a loading rack at Cressier and a digester hall at a cantonal wastewater works. This page sets out how an explosion proof smartphone supply route to Switzerland will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An explosion proof smartphone for Switzerland cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Switzerland: Schaffhausen, Cressier, Basel and Schweizerhalle | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Switzerland. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS Switzerland market guide.

Hydraulic power was used instead of steam in Swiss industry because of the mountainous terrain and lack of coal, which explains the concentration of hydro stations and tunnels in the Alps.
Switzerland produces no fossil fuels and imports petroleum, so refining and bulk fuel handling is limited, while storage depots and distribution terminals are the main flammable-liquid sites.
The three Rhine ports around Basel handle about six million tonnes and over 120,000 containers a year, roughly 10% of Swiss imports and a third of the country's mineral oil products.
“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 Switzerland. Explosion-proof is the everyday phrase, but at a Swiss fine chemical plant the real subject is solvent atmospheres in a validated building. Flameproof Ex d suits heavy enclosures, while the IS-04Z1 uses intrinsic safety to limit the energy of a handheld, which a reviewer weighs against cleaning and airlock procedures.
There is no stock to order for Switzerland yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.

Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
The market guide for Switzerland covers Basel and Schweizerhalle, Visp, Monthey, Kaisten and the Fricktal, among others. Site-level pages are linked below.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Switzerland is not an EU member, but it generally aligns its equipment rules with European requirements, so ATEX-marked devices are commonly accepted. Confirm the current requirement and any Swiss conformity marking with the site operator or your importer before ordering.
German, French and Italian are all national languages depending on the canton, and many industrial sites also work in English. Ask the operator which language it requires for instructions and certificates, and provide the declaration of conformity together with the Ex marking details.
IP68 sealing and a rugged build are aimed at a cleaned plant rather than a rained-on one, but your cleaning agents and routine must be checked. Test a unit with your own procedure and confirm compatibility with the site's validation team.
