Refinery status
The refinery has been shut and restarted repeatedly since 2025, and NNPC signed a memorandum with Chinese firms in April 2026 on restart plans; confirm current status first.
Warri is an oil hub in Delta State, hosting the Warri Refinery and Petrochemicals at Ekpan and Ubeji, many international oil company offices and a seaport. Chevron's Escravos gas plant and gas-to-liquids plant lie in the western Niger Delta. This page explains what to look for in an ATEX and IECEx mobile phone for Warri, 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 Warri: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. 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 |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |
| Where it applies | Warri: Refinery process units, Gas plants and gas-to-liquids facilities, Seaport and jetty fuel handling | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Warri. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Rail, roads, helipads and local jetties all serve the area, and boat transport is common to reach creek sites.
Warri sits on the Warri River, which joins the Forcados and Escravos rivers through Jones Creek in the lower Niger Delta, so creeks and rivers shape how people and equipment reach many sites.
Warri has a tropical monsoon climate with a mean annual temperature of about 26.7 C and roughly 2,770 mm of rain a year, so humidity and water ingress are routine concerns for portable equipment.
A standard-gauge railway of roughly 275 km links the Ajaokuta steel mills to Warri port; the line was officially inaugurated in September 2020 with its terminal at Udu.
Warri is described as one of the main hubs of Nigeria's petroleum industry, with the Warri Refinery and Petrochemicals at Ekpan and Ubeji and many oil company operational offices located close by.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Warri. Warri hosts many international oil company offices and the Escravos gas and gas-to-liquids plants lie nearby, so reviewers see contractor packs from firms with international standards. ATEX and IECEx evidence together suits them. The IS-04Z1 has no certificate yet, as certification is in progress.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are refinery process units, gas plants and gas-to-liquids facilities, seaport and jetty fuel handling. 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.
Access mixes road, river and air. Company yards have helipads, creeks link to the Forcados and Escravos rivers, and the Osubi airport handles scheduled flights. Confirm with the operator which route your visit uses, because carry-on rules for powered devices can differ by transport.
Sea freight typically enters through the Delta Ports facilities at Warri, which handle most import and export cargo, while a rail link to the Ajaokuta steel mills now ends at Udu. Confirm customs clearing, import duty and type-approval needs with a local freight agent before shipping.
Rail, roads, helipads and local jetties all serve the area, and boat transport is common to reach creek sites. Plan device protection against rain and spray, and keep spare charged units. Ask the operator about access and permits.
