Poland: background
Poland produced 78 megatonnes of hard coal and 57 megatonnes of brown coal in 2009, and a plan agreed in September 2020 aims to phase out coal by 2049.

Intrinsically Safe Smartphone 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 intrinsically safe smartphone for Poland, and where the IS-04Z1 stands against that list today.

WherePoland
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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. 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: industry on the ground
Poland's energy sector is the fifth largest in Europe, with an installed electricity capacity of about 61 GW at the end of 2024, so power plants and mines are large sources of classified areas.
Poland: industry on the ground
In 2020 coal made up 69.5% of national energy production and 68.5% of electricity generation, so coal handling, bunkers and mills create combustible dust zones at many power sites.
Poland: background
PKN Orlen was created in 1999 by merging the state fuel retailer CPN with Petrochemia Płock, the firm running the Płock refineries, and has since grown into a multinational refiner and gas trader.
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 Poland. A cold, wet outdoor round at Płock, Gdańsk or Police is a long shift with no safe-area charging. An intrinsically safe handheld lets an operator log findings, photograph equipment and open a work-order app without leaving the zone. It suits turnaround work at Puławy and Kędzierzyn-Koźle as well.

Specifying an intrinsically safe smartphone 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 intrinsically safe smartphone 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 intrinsically safe smartphone in Poland 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.
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 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.
Where does Poland's combustible dust risk concentrate?
Coal-fired power stations, including large brown coal plants such as Bełchatów, along with coal-using industry, handle bulk fuel that creates dust zones such as Zone 21 and Zone 22. Check that a device's dust group and temperature class match the site classification drawings.
Do Polish coal mines need different equipment from power plants?
ATEX separates Group I equipment for mining from Group II for surface industries, and underground methane and coal dust conditions differ from surface plant. Check the group marking on any device against the area and the mine operator's own approval procedure.
Can the IS-04Z1 be used in Polish coal mines?
No. It is designed as Group II surface equipment, and underground coal mining is Group I, with a separate certificate for methane and coal dust. Do not take a Group II device underground. Refineries, fertiliser plants and gas terminals are the intended areas, subject to the site operator's classification.
