Ex-Proof Mobile Phone in Salalah
APM Terminals manages the Port of Salalah, a major transshipment hub, which lies outside the city to the south and is the largest private employer in Dhofar. OQ Base Industries runs Oman's integrated methanol, ammonia and LPG complex in the free zone, which is where most hazardous-area work is found. This page explains what to look for in an Ex-proof mobile phone for Salalah, and where the IS-04Z1 stands against that list today.

Field notes · Salalah
More about Salalah that matters for portable equipment
Salalah: rules and approvals
Oman's TRA type approval is valid for four years and needs a local representative and a compliance mark for telecom equipment.
Salalah: climate and equipment wear
The city has a hot desert climate, but summers are cooler than in northern or inland Oman.
Salalah: infrastructure
The Salalah Free Zone beside the port is developing as a centre for heavy industries, so most hazardous-area activity is at the port zone rather than the city.
Salalah: background
The Port of Salalah has operated since 1998 and is the largest port in Oman, with a container terminal and a general cargo terminal serving East Africa, the Red Sea, the Indian subcontinent and the Gulf.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Salalah. For methanol, ammonia or LPG areas, a marking check reads zone, gas group and temperature class on the label and compares each with the plant's classification. LPG and methanol belong to different gas groups, so the target marking II 2 G Ex ib IIC T4 should be compared with the operator's records, and ammonia needs its own check.

Questions · Salalah
Frequently asked questions
Can we buy an Ex-proof mobile phone in Salalah today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an Ex-proof mobile phone in Salalah 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Salalah would use it?
Likely candidates are methanol and ammonia production, lpg extraction and storage, port liquid bulk handling. 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.
Where is the industrial work in Salalah?
Typically in the Salalah Free Zone beside the port, which lies south of the city, where heavy industry is developing. The city itself is largely commercial and residential.
How do I ship equipment to Salalah?
Through the Port of Salalah, managed by APM Terminals, or by air and road from Muscat. Customs clearance and free-zone rules depend on your agent.
Who sets site rules in the Salalah Free Zone?
Plant operators and the free zone set their own site rules and supplier requirements. Ask the specific operator, such as the methanol, ammonia or LPG plant, what it needs for portable devices. Confirm with the operator.
