Pipeline link
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.

Explosion-Proof Mobile Phone in Göteborg
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. Göteborg Landvetter Airport is 25 km south-east of the centre, and the city has the largest tram network in Scandinavia with over 80 km of double track, though soft ground means there is no metro. This page explains what to look for in an explosion proof mobile phone for Gothenburg (Göteborg), and where the IS-04Z1 stands against that list today.

The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Gothenburg (Göteborg). Around tanker berths and loading arms, people say explosion-proof loosely. In practice, flameproof Ex d suits fixed pump motors and junction boxes, while a handheld phone relies on intrinsic safety. Refinery units, valve areas and bulk fuel storage each need a defined protection concept chosen by the operator's engineers.

Specifying an explosion proof mobile phone for Göteborg
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 · Göteborg
Frequently asked questions
Can we buy an explosion proof mobile phone in Göteborg 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 explosion proof mobile phone in Göteborg cost?
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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which areas at Gothenburg (Göteborg) would use it?
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.
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.
Is Gothenburg a good base for work across western Sweden?
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.
Does the Gothenburg climate affect handheld equipment?
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.
What entry checks apply to contractors at Gothenburg's Energy Port?
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.
