Hot climate
Summers are very hot on this stretch of the Gulf of Oman coast, so handset heat tolerance matters for outdoor rounds.

Intrinsically Safe Smartphone in Sohar
Sohar is the capital of Al Batinah North Governorate and hosts SOHAR Port and Freezone, a deep-sea industrial port on the Gulf of Oman. Refining, metals and iron-ore processing are clustered there, which creates Zone 1 and Zone 21 work in process plants and bulk-liquid storage. If you are specifying an intrinsically safe smartphone for Sohar, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Sohar that matters for portable equipment
Sohar: background
The first lease at the new port was signed with Sohar Refinery in 2003, and the free zone itself was established in 2010, so many plants are of 2000s to 2010s vintage.
Sohar: infrastructure
Hafeet Rail is building a 238 km line to connect the port with the UAE national network, and its first track shipment arrived through the Steinweg general cargo terminal.
Sohar: who works there
C. Steinweg Oman holds the concession for dry bulk, break-bulk, roll-on/roll-off and container stuffing operations in the port, so cargo-side contractors work under a separate terminal operator.
Sohar: rules and approvals
Oman's Telecommunications Regulatory Authority follows EU-style type-approval procedures for radio equipment and issues a TRA label; a self-declaration route has also been introduced, so confirm the current path.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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 Sohar. Inspection and turnaround crews at the refinery and port move between process units, tankage and berths. An intrinsically safe handheld lets them keep photos, readings and permits on one device through classified areas. That is the purpose of the IS-04Z1 design, subject to certification and operator acceptance.

Specifying an intrinsically safe smartphone for Sohar
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 · Sohar
Frequently asked questions
Can we buy an intrinsically safe smartphone in Sohar today?
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.
What does an intrinsically safe smartphone in Sohar cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
Which areas at Sohar would use it?
Likely candidates are refinery process units, port liquid bulk handling, fuel and chemical storage, industrial plant utilities. 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.
Does heat at Sohar affect handset choice for outdoor rounds?
Summers are very hot there, so check the datasheet operating and charging temperature range, keep devices out of direct sun on jetties, and plan battery swaps for long shifts. Ask the plant operator whether it sets its own temperature limit for portable devices.
Can UAE-based service teams reach Sohar easily?
Sohar has road links towards the UAE, and the Hafeet Rail corridor is being built to join the port to the UAE network. For hazardous areas, border and site-access paperwork still sits with the client, so allow time for permits and inductions.
Do I need separate approvals for each Sohar operator?
Each operator at the port runs its own supplier approval and permit system, so one approval does not cover all. Ask the refinery, port company or industrial plant what it requires for portable devices. Confirm with the operator.
