Where hazardous-area demand sits
ADNOC says its downstream strategy is focused on the Ruwais refining and petrochemical complex, so buyers targeting refinery work should look there rather than at Umm Al Nar.

Ex-Proof Mobile Phone in Umm Al Nar Refinery
The protected archaeological site is fenced by a concrete wall of about 1,760 m, and it lies between a refinery and a sensitive military area, so works near it face heritage constraints. ADNOC shut it in 2022 and focused its downstream refining and petrochemicals strategy on Ruwais, so current Zone 1 work is elsewhere. This page explains what to look for in an Ex-proof mobile phone for Umm Al Nar (former ADNOC refinery), and where the IS-04Z1 stands against that list today.

More about Umm Al Nar (former ADNOC refinery) that matters for portable equipment
Umm Al Nar (former ADNOC refinery): background
The first archaeological excavations in Abu Dhabi began at Umm Al Nar in 1959, twelve years before the UAE was founded.
Umm Al Nar (former ADNOC refinery): rules and approvals
UAE handsets need type approval from the federal Telecommunications and Digital Government Regulatory Authority, and any remaining fuel or gas facility nearby will set its own device rules.
Umm Al Nar (former ADNOC refinery): projects and investment
The Department of Culture and Tourism Abu Dhabi has run three seasons of fieldwork at the island since 2020, so archaeology and industrial clearance can overlap in time.
Umm Al Nar (former ADNOC refinery): background
The island gave its name to the Umm Al Nar Bronze Age culture of about 2600 to 2000 BCE, so it is better known archaeologically than as a refinery site.
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 Umm Al Nar (former ADNOC refinery). A marking check on a former refinery would start with whether any zone classification remains active during clearance. Where a decommissioned unit is still being purged or opened, the operator decides the zone, gas group and temperature class. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, still pending certification, so check it against that classification.

Questions · Umm Al Nar Refinery
Frequently asked questions
Can we buy an Ex-proof mobile phone in Umm Al Nar Refinery 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 Ex-proof mobile phone in Umm Al Nar Refinery 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 Umm Al Nar (former ADNOC refinery) would use it?
Likely candidates are decommissioned refinery process units (former), site clearance and demolition works, relocated process units being reassembled elsewhere in the uae. 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.
Why is access to Umm Al Nar island restricted?
The island is reached across a bridge restricted to pass holders. It also holds a protected archaeological site between a refinery and a sensitive military area, so public access is prohibited. Contractors need a pass arranged through the site owner or main contractor.
Is there still hazardous-area work at Umm Al Nar?
Possibly limited. The former refinery was shut in 2022, so current work is mainly decommissioning, clearance and site works, which can still involve residual hydrocarbons and gas-freeing. Confirm the current status and rules with the site owner before specifying devices.
Is there still hazardous-area work at Umm Al Nar?
ADNOC states that the refinery stopped operating in 2022 and the land is being redeveloped. Some clearance and demolition activity may involve residual classified areas, but live refinery work has moved on. Confirm with the site operator what classification, if any, still applies to a given work package.
