Not inside the tank
The interior of a crude or fuel tank is Zone 0. The IS-04Z1 is designed for Zone 1 and Zone 21, so it does not go inside a tank, and tank entry stays on the operator’s own procedures.

Explosion proof mobile phone for PERN in Poland
PERN moves crude oil and fuel across Poland: pipelines from Płock to Gdańsk and from the east, crude tank farms near Płock, at Adamowo and at Gdańsk, and a chain of fuel bases from Koluszki to Boronów. This page is for PERN’s HSE and operations teams, and the contractors working on its terminals, who want an explosion proof mobile phone in Poland suited to tank farm work. The IS-04Z1 is designed for Zone 1 and Zone 21; 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 PERN: tank farms, pump stations and fuel bases
A tank farm is a place where vapour is released slowly and constantly, which is why its classification is drawn around rim seals, vents, pumps and manifolds rather than around buildings. PERN’s crude bases are at Miszewko Strzałkowskie near Płock, at Adamowo and at the Gdańsk Oil Terminal; PERN describes close to three million cubic metres of crude storage across the three. Product moves on from Płock through the Płock–Koluszki–Boronów line to fuel bases that include Koluszki, Boronów, Rejowiec, Emilianów, Dębogórze and Małaszewicze. At Gdańsk the tank farm works with the marine terminal operated by Naftoport. Refineries such as the Orlen refineries at Płock and Gdańsk are both PERN’s customers and its neighbours.
Assets
- Miszewko Strzałkowskie
- Crude base near Płock, the inland hub for the refinery.
- Adamowo
- Crude base in the east where supply from that direction arrives.
- Gdańsk Oil Terminal
- Crude tanks fed by the Naftoport marine terminal and the Pomeranian pipeline.
- Pomeranian pipeline
- Two-way line linking Płock and Gdańsk.
- Płock–Koluszki–Boronów line
- Product pipeline serving the fuel bases to the south and east.
- Fuel bases
- Koluszki, Boronów, Rejowiec, Emilianów, Dębogórze and Małaszewicze receive and dispatch finished fuel.
Where the zones fall
- Floating roof tanks
- Vapour at the rim seal and above the roof; the outside of a tank shell is not the same as the inside.
- Pump halls and manifolds
- Seals and flanges that weep slightly, which is why classification covers them.
- Valve pits and pig traps
- Launching and receiving pigs opens the line and creates a temporary release.
- Loading racks
- Vapour displaced from road tankers and rail wagons during filling, gas group IIA with gasoline.
- Bunds and drainage
- Low points where heavier vapour collects.
- Control buildings and laboratories
- Outside the zones; the sample and dispatch records are made here.
Built for local conditions
What a tank farm does to a handset
A tank farm is open ground with a lot of steel on it. The questions are how far people walk, how cold it gets and what the handset may not be taken into.

Rim seals and gauge hatches
Reading a level or taking a sample at the roof is a Zone 1 activity. A handset that can photograph the gauge and the sample label at that point removes a trip back to the office.
A pipeline route that is mostly fields
Valve stations are far from the next building. Four-constellation GNSS gives the line walker a coordinate, and IP68 keeps rain and mud from stopping the handset.
Batches that change the product
Fuel bases receive products in sequence and sample at each change. Dated photographs and readings entered at the point of sampling are harder to dispute later.
Contractors on inspection campaigns
Tank inspection and maintenance bring specialist contractors in for weeks. Enrol the handset when they arrive and wipe it when they go, using your EMM or MDM.
Use cases · PERN
Where a PERN team would use the IS-04Z1
Storage01
Tank farm inspection rounds
Walk the tank shells, bunds and manifolds, photograph a leak or a corroded fitting, and record its location; the report then exists before the walk ends.
Fuel bases02
Receipt, sampling and loading
At a base such as Koluszki or Boronów a handset carries the receipt checklist into the loading area and records the sample, so the paper form is not rewritten later.
Pipeline03
Line walks and valve station checks
Two people on a long route need a call, a position and a camera. One Zone 1 handset replaces three items.
Questions · PERN
Frequently asked questions
Can the handset be used on a floating roof?
The rim seal area is normally treated as a Zone 1 or Zone 2 location, but it is the operator’s classification that decides. The device is designed for Zone 1; the inside of a tank is Zone 0 and outside its design target.
Does crude oil put the temperature class at risk?
The marking target is T4, and many crude and product vapours have ignition temperatures well above that, but check the lowest auto-ignition temperature of anything stored at the site against the marking on the certificate.
How would PERN assess a handset for a terminal?
That is PERN’s procurement and HSE process. Ask for its technical requirements for portable electronic equipment, and whether contractors’ equipment must be registered. SAMS has no relationship with PERN, and this page does not imply one.

Ask about the IS-04Z1 for PERN, 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.
