Equipment reused elsewhere
ADNOC says the refinery's processing units are being refurbished and reassembled at a location within the UAE, where more than 240 specialist staff will be employed.
Umm Al Nar Island in Abu Dhabi hosted the UAE's first refinery, inaugurated in 1976, which processed up to 85,000 barrels a day at its peak. Umm Al Nar island lies next to the city of Abu Dhabi and has been enlarged by land reclamation and dredging, so the current shoreline differs from the original. If you are specifying a hazardous area smartphone for Umm Al Nar (former ADNOC refinery), this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Umm Al Nar (former ADNOC refinery): 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 |
|---|---|---|
| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |
| Area drawing | The operator's own classification drawing | Decided by the site operator |
| Where it applies | Umm Al Nar (former ADNOC refinery): Decommissioned refinery process units (former), Site clearance and demolition works, Relocated process units being reassembled elsewhere in the UAE | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Umm Al Nar Refinery. 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.
ADNOC says the refinery's processing units are being refurbished and reassembled at a location within the UAE, where more than 240 specialist staff will be employed.
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.
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 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.
Access to the island is across a bridge and is restricted to pass holders, so any clearance or demolition crews need site passes arranged in advance.
The first archaeological excavations in Abu Dhabi began at Umm Al Nar in 1959, twelve years before the UAE was founded.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Umm Al Nar (former ADNOC refinery). Umm Al Nar no longer hosts the UAE's operating Zone 1 refinery work, since ADNOC consolidated downstream refining and petrochemicals at Ruwais in the Al Dhafra region. Former process units, tank areas and equipment being dismantled may still carry residual classification, and the operator, not SAMS, decides it. Buyers seeking live refinery areas should look at Ruwais.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted 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.
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.
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.
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.
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.
