Poland: infrastructure
Bełchatów Power Station in the Łódź region supplies almost 20% of Poland's energy and is the largest brown coal power plant in the EU, a major example of a large dust-hazard site.

Explosion-Proof Cell Phone in Poland
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for the refinery, fertiliser and gas terminal work where Polish teams actually meet an explosive atmosphere. This page explains what to look for in an explosion proof cell phone for Poland, and where the IS-04Z1 stands against that list today.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Poland: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

More about Poland that matters for portable equipment
Poland: projects and investment
Solar energy expanded by 51.39% in 2023 and 26.61% in 2024 while hard coal fell 16.96% in 2024, and nuclear power is being introduced, so the types of site are changing.
Poland: industry on the ground
The Płock refinery and petrochemical complex is the largest oil refinery in Poland, and Orlen's headquarters are in the same city, with servicing and construction firms clustered around the plant.
Poland: industry on the ground
Coal use splits into 75.6% for electricity and heat, 14.5% for industry and 9.9% for buildings, so industrial coal consumers beyond power plants also have dust and gas hazards.
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 Poland. Polish plants say wybuchoodporny for anything used near hydrocarbons, but the concepts differ. Flameproof Ex d suits fixed motors and fittings, while the IS-04Z1 uses intrinsic safety, Ex ib. That suits a handset on a Płock refinery round or at the Świnoujście LNG terminal, where one person visits many areas.

Specifying an explosion proof cell phone for Poland
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 · Poland
Frequently asked questions
Can we buy an explosion proof cell phone in Poland 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 explosion proof cell phone in Poland 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.
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 Poland does this cover?
The market guide for Poland covers Płock, Gdańsk, Włocławek, Puławy, 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.
What language should Polish sites receive documentation in?
Polish is the working language and ATEX instructions are typically expected in the language of the destination country. A Polish-language instruction sheet with certificate pack usually speeds up site acceptance. Ask the operator whether English documents are also accepted for contractors.
Does Poland follow ATEX for handheld devices in hazardous areas?
Poland is an EU member, so ATEX Directive 2014/34/EU applies to equipment and Directive 1999/92/EC to workplace zoning. Zone 1 and Zone 2 devices should carry CE and Ex markings with instructions in Polish. Operators and mines usually add their own approval rules.
Does one device cover both gas and dust on a fertiliser site?
The gas marking target is II 2 G Ex ib IIC T4, and Zone 21 dust protection belongs to the same programme, so one device is designed to cover both. Certification is in progress, so confirm the final marking and the plant's zone drawing with the operator.
