Switzerland: infrastructure
Switzerland relies mainly on hydroelectric power, nuclear power and natural gas, and plans to phase out its five nuclear power plants as they reach the end of their lives, with 2044 given as a phase-out date.

Short answer. A hazardous area cell phone 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

More about Switzerland that matters for portable equipment
Switzerland: industry on the ground
Basel is Switzerland's main pharmaceutical centre, home to both Novartis and Roche.
Switzerland: infrastructure
Petroleum and motor fuels account for 43% of energy consumed, electricity 26% and gas 15%, with households and transport each using about one third and manufacturing and services each just under one fifth.
Switzerland: industry on the ground
Machinery, chemicals, vehicles and metals are leading industries, so classified areas occur more in chemical and pharmaceutical plants and process industry than in oil and gas.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Switzerland. Swiss classified areas are concentrated rather than sprawling: the Basel cluster running up the Rhine to Valais and Chablais, the Cressier refinery, fuel depots, and biogas and wastewater plants with Zone 1 and Zone 2 areas in almost every canton. The operator classifies these. SAMS does not classify any area.

Questions · Switzerland
Frequently asked questions
Can we buy a hazardous area cell phone in Switzerland today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does a hazardous area cell phone in Switzerland cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Which sites in Switzerland does this cover?
The market guide for Switzerland covers Basel and Schweizerhalle, Visp, Monthey, Kaisten and the Fricktal, among others. Site-level pages are linked below.
How will SAMS supply Switzerland?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Which Swiss industries need intrinsically safe phones?
Chemical and pharmaceutical plants, fuel depots, gas networks, wastewater and biogas plants, and some manufacturing lines. The economy leans on machinery, chemicals, vehicles and metals more than oil and gas. Ask each site for its explosion protection document to see where zones exist.
How does mountain weather affect Ex handheld devices in Switzerland?
Alpine sites can be very cold, with snow and large temperature swings, which reduces battery capacity and affects touchscreen use with gloves. Check the lowest rated ambient temperature on the certificate and the water ingress rating, and carry spare batteries in warm storage.
Which languages does the handset support for Swiss users?
Android 16 carries German and the other working languages used in Switzerland, according to the sheet. Confirm the specific language packs and keyboard layouts you need during an evaluation, particularly for crews who work across language regions.
