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.
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. If you are specifying a hazardous area cell phone for Poland, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Poland. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS Poland market guide.
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.
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.
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.
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.
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 Poland. Polish hazardous areas sit in belts: refining and petrochemicals at Płock and Gdańsk, fertilisers and polymers from Włocławek through Puławy and Kędzierzyn-Koźle to Police, and gas infrastructure around Świnoujście and Baltic Pipe. Upper Silesian coal mining is Group I and is not counted in. Operators classify their own areas.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
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.
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.
The market guide for Poland covers Płock, Gdańsk, Włocławek, Puławy, among others. Site-level pages are linked below.
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.
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.
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.
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.
