Czech Republic: infrastructure
The Gazela pipeline connects Czech gas supply through Germany at Brandov or Rozvadov and through Slovakia at Lanžhot, so compressor and metering stations sit near the borders.

WhereCzech Republic
Short answer. An intrinsically safe smartphone for Czech Republic 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Field notes · Czech Republic
More about Czech Republic that matters for portable equipment
Czech Republic: infrastructure
In 2022 electricity production was 78.8 TWh, of which 53.6% came from fossil fuels, mostly lignite, and 40.95% from nuclear, so coal-handling plants and power stations are typical dust and gas sites.
Czech Republic: rules and approvals
ATEX equipment is split into Group I for mining and Group II for surface industries, which matters in a country with coal mining as well as refining and chemicals.
Czech Republic: industry on the ground
Gas use was 9.4 billion cubic metres in 2021 and 7.1 billion in 2023, so gas distribution and industrial gas burners remain widespread across Czech industry.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Czech Republic. Rounds at Záluží, Nelahozeves or Ostrava involve walking long distances across extended plants in cold weather, with no charger inside a classified area. An intrinsically safe handheld is designed for those rounds, with a 4,000 mAh battery sized for a whole shift with the camera and a maintenance application in use.
The route · supply
Sourcing the IS-04Z1 for Czech Republic
There is no stock to order for Czech Republic 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.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Questions · Czech Republic
Frequently asked questions
Can we buy an intrinsically safe smartphone in Czech Republic today?
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.
What does an intrinsically safe smartphone in Czech Republic cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Which sites in Czech Republic does this cover?
The market guide for Czech Republic covers Litvínov and Záluží, Kralupy nad Vltavou, Neratovice, Valašské Meziříčí, among others. Site-level pages are linked below.
How will SAMS supply Czech Republic?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Do Czech mines need different Ex equipment from refineries?
Yes. ATEX separates Group I equipment for mining from Group II for surface industries, and methane and coal dust conditions underground differ from refinery gas and vapour. Check the Group marking on any device against the area and the mine operator's own approval process.
How do pipeline terminals in the Czech Republic affect device planning?
Crude arrives by pipeline from Germany and Italy, with storage at depots such as Nelahozeves, so many classified areas are at pumping and storage sites rather than ports. Terminal operators run their own induction and device registration, so schedule approvals early for shutdown work.
Must the instructions be in Czech?
Czech law expects the instructions in Czech, so the manual, safe-use guidance and declaration of conformity are planned in Czech alongside English, with a Czech interface on Android 16. That is planned into the launch rather than translated afterwards. Certification is in progress. Check requirements with your safety officer.
