Hydrogen beside hydrocarbon
Gas group IIC covers hydrogen. The marking target is II 2 G Ex ib IIC T4, so a handset used in a hydrotreater unit is not limited to the hydrocarbon half of the plant.

Explosion proof mobile phone for Refining and Petrochemicals in Poland
Poland’s refining and petrochemical hazardous areas are concentrated at Płock and Gdańsk, at the Orlen Południe sites in the south, and in the downstream plants alongside them. This page is for HSE, maintenance and telecoms teams at those sites and the contractors who work on their units, who need an explosion proof mobile phone in Poland for Zone 1 and Zone 21 work. The IS-04Z1 is designed for that; certification is in progress ahead of Q4 2026. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.

Explosion proof mobile phone for Polish refining and petrochemicals
This page takes the sector view: what each type of unit does to a handset, whoever owns it. For the operator’s organisation and sites, see explosion proof mobile phone for Orlen. Płock is both refinery and petrochemical plant, and Gdańsk is a refinery with a coking complex commissioned in the EFRA programme. Orlen Południe works with biocomponents at Trzebinia and with base oils and oil regeneration at Jedlicze. A refinery is not one hazard but a series: crude distillation, hydrotreating, conversion, sulphur recovery, olefins, polymers, loading. Each has its own gas group, its own temperature class and its own turnaround. The Płock complex is the larger of the two and carries the olefins and polymer chain; Gdańsk is a coastal site where crude, product and coke move by ship, pipeline and rail. Orlen’s subsidiary Anwil, at Włocławek, takes chemistry further into PVC, and the chemical plant view covers that side.
Unit types and where to find them
- Crude distillation
- Płock and Gdańsk; hot hydrocarbon liquid and vapour, gas group IIA.
- Hydrotreating and conversion
- Hydrogen at pressure; gas group IIC and a leak is hard to see.
- Sulphur recovery
- Hydrogen sulphide, toxic and flammable at once, so the personal monitor is the primary tool.
- Coking
- Gdańsk; heavy residue converted to coke, with coke dust in handling areas.
- Olefins and polymers
- Płock; ethylene, propylene and polyolefin powder.
- Biocomponents and base oils
- Trzebinia and Jedlicze; methanol and flammable liquids in smaller plants.
- Flare, utilities and tank farms
- Product and intermediate storage at both main sites, with flare headers that vent during upsets.
How the work is organised
- Shift rounds
- Operators walk fixed routes in each unit and record readings.
- Turnaround
- Planned shutdowns of one unit at a time, with contractor numbers many times the permanent staff.
- Permit to work
- Every job in a classified area runs under a written permit, which is where handset rules are set.
- Contractor fleets
- Mechanical, electrical and instrument contractors arrive with their own devices and procedures.
- Marine and rail loading
- Gdańsk jetty and rail racks, where vapour is released during filling.
- Control rooms
- Outside classification, but the point at which the handset gets its instructions.
- Hot work and isolation
- Jobs that break containment are issued only after isolation and gas testing, and the handset carries the permit, not the ignition source.
Built for local conditions
What a refinery does to a handset
The device’s job is to survive and stay legitimate in a hazardous area for a full shift, again and again, with contractors who come and go.

Hydrogen sulphide needs a monitor
No phone replaces a personal H2S monitor. What the IS-04Z1 adds is an alarm record, a position and a photograph of the cause.
Dust where a unit has solids
Polyolefin powder and coke dust call for Zone 21. That is part of the same programme, so a round that crosses from vapour to powder does not need a second device.
A turnaround is a staffing event
During a shutdown, hundreds of contractors can arrive within days. Enrolment, restriction and wiping through EMM and MDM turns that into a procedure.
Cold and wet outdoors
IP68 sealing and a rugged build are aimed at outdoor work in winter, and the ambient range will be fixed by the certificate rather than promised in advance.
Position, not just a photograph
A refinery has thousands of tag numbers and many look alike. A GNSS position, four constellations, plus a photograph removes doubt about which flange the report refers to.
Use cases · Refining
Where refinery and petrochemical teams would use the IS-04Z1
Operations01
Unit rounds
Readings, a photograph and a location go to the maintenance planner without a stop at the control room.
Turnaround02
Shutdown and start-up
The permit, drawings and checklists sit on one device, locked to the approved applications.
Loading03
Jetty, rail rack and road gantry
Supervisors carry voice, camera and position into the loading area where vapour is released, and the loading record is made there instead of at the end of the shift.
Questions · Refining
Frequently asked questions
Which gas groups does a refinery need?
Most hydrocarbon work is gas group IIA; ethylene is IIB; hydrogen is IIC. A handset marked IIC covers all three, but the temperature class and the zone still have to match each area.
Does Płock differ from Gdańsk for equipment suppliers?
The certificate does not, but each site keeps its own classification drawings, permit procedures and contractor induction. Ask each site what it needs, and do not assume that one site’s answer applies to the other.
Does a turnaround change the approval route?
Not the certificate, but the permit regime. Contractor equipment is usually reviewed by the operator’s HSE team before it is used, so ask what evidence they need.
Is this device approved for Polish refineries?
No. Certification is in progress, SAMS has no pilot or order at a Polish refinery, and the decision to allow it belongs to each operator.

Ask about the IS-04Z1 for Refining and Petrochemicals, Poland
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Poland. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
