Offices outside the city limit
Equinor's Oslo office and Aker Solutions are at Fornebu, which lies in Baerum municipality rather than Oslo itself.
Oslo is Norway's capital and a major maritime and energy-company centre. Oslo sits at the northern end of the Oslofjord, with a municipal population of 724,290 in 2025, a greater urban area of about 1.1 million, and a metropolitan area of roughly 1.5 million. This page explains what to look for in an explosion proof smartphone for Oslo, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Oslo: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. 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 |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Oslo: Petroleum product storage and loading, Methanol and bulk cargo handling, Fuel depots | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Oslo. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
Equinor's Oslo office and Aker Solutions are at Fornebu, which lies in Baerum municipality rather than Oslo itself.
Sjursoya handles container, ro-ro, dry bulk and petroleum cargo.
Oslo has a humid continental climate with fairly cold winters and some of the warmest summers in Norway, and the driest seasons are winter and spring while summer and autumn are wettest.
The waterfalls of the Akerselva powered some of Norway's first modern industry in the 1840s, and the city's population grew from about 10,000 in 1814 to 230,000 by 1900.
The city is a hub of Norwegian trade, banking, industry and shipping, and an important centre for maritime industries, with many of the world's largest shipping companies, shipbrokers and marine insurers based there.
Oslo Gardermoen airport lies 35 km north-east of the city, so air freight and visitors arrive well outside the urban area and then travel by road or rail.
“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 Oslo. At the Sjursoya petroleum and methanol areas, explosion-proof is a common spoken term, but the actual concepts differ. Flameproof Ex d suits fixed equipment with strong housings, while a handheld for terminal rounds suits intrinsic safety. The IS-04Z1 is designed around intrinsic safety, not around a flameproof casing.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
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.
Likely candidates are petroleum product storage and loading, methanol and bulk cargo handling, fuel depots. 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.
Largely, yes. The city is a hub of shipping, banking and trade, with many maritime company headquarters, while major process plants and offshore bases lie elsewhere in Norway. Many suppliers meet buyers in Oslo, then arrange site visits and deliveries separately.
Gardermoen airport is 35 km north-east of the city, and sea freight arrives through Oslo's port. Norway is outside the EU customs union, so allow time for customs declarations and confirm any approval requirements for electrical and radio equipment with your forwarder.
Winter months average around minus 2 C and most January days are below freezing, so battery performance and operating range matter. Check the certified ambient temperature range, keep the phone warm between tasks and charge in a safe area. Ask the operator about cold-weather practice.
