Port access
The Energy Port runs ISPS security level 1 with gate controls, including random alcohol testing at Gate 1, so visitors and contractors pass formal entry checks.
Gothenburg hosts Sweden's largest general energy port, with about 2,200 tanker calls a year and 20.7 million tonnes of energy products handled in 2025, and the Preemraff Göteborg refinery nearby. Tanker loading, tank storage and refinery units create Zone 1 areas. If you are specifying an intrinsically safe smartphone for Gothenburg (Göteborg), 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 Gothenburg (Göteborg): 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.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | Gothenburg (Göteborg): Refinery process units, Tanker berths and loading arms, Pumping stations and valve areas | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Göteborg. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
The Energy Port runs ISPS security level 1 with gate controls, including random alcohol testing at Gate 1, so visitors and contractors pass formal entry checks.
Crude oil reaches the refinery by pipeline from a tanker port a few kilometres away, so classified areas are spread between port and refinery sites.
Chalmers University of Technology and technical schools linked to SKF and Volvo supply engineering talent, so trained technicians for industrial and marine work are available locally.
Gothenburg has an oceanic climate moderated by the Gulf Stream, with summer highs of 20 to 22 degrees Celsius, windy winters between about minus 1 and 4 degrees, and moderate rain through the year.
The Götaverken shipbuilding company was founded in 1841 and stayed in business until 1989, which left a legacy of marine engineering skills and waterfront industrial land.
Major companies operating plants in the area include SKF, Volvo cars and trucks, and Ericsson, and Volvo Cars is the largest single employer in Gothenburg, not counting supplier jobs.
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 Gothenburg (Göteborg). Rounds across pumping stations, valve areas and tanker berths involve many short stops in Zone 1 areas. A handheld intrinsically safe device would let an operator record readings and photograph equipment at each stop, without carrying a separate terminal. The IS-04Z1 is designed for that style of short, frequent data capture.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.
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.
Likely candidates are refinery process units, tanker berths and loading arms, pumping stations and valve areas, bulk fuel tank storage. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Yes. The city sits on the west coast with an international airport, a large port and regional rail and road links, and a deep technical workforce from local industry and universities. Plan travel to individual sites separately and confirm each site's induction rules.
The climate is mild for its latitude, but winters are cold and windy and rain is regular, with salt air near the harbour. Typically users want good ingress protection, battery performance in cold weather and routine cleaning of exposed connectors.
The Energy Port runs ISPS security level 1 with gate controls, including random alcohol testing at Gate 1, so visitors and contractors pass formal entry checks. Device approval is separate and set by the operator. Ask the port or refinery HSE team what evidence they expect for a phone.
