Humid tropics
Annual rainfall is about 2,770 mm, with a dry season from November to April and rains from May to October.
Beyond oil and gas, the Warri area includes Delta Steel Company in the Ovwian-Aladja area of Udu, a Beta Glass plant near Ughelli and a power station at Ughelli, about 15 minutes away by car. Chevron's Escravos gas plant and gas-to-liquids plant lie in the western Niger Delta. If you are specifying an IECEx mobile phone for Warri, 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 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 |
|---|---|---|
| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |
| 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.
The companies on site and the hazardous-area types a handset is likely to meet there.
Annual rainfall is about 2,770 mm, with a dry season from November to April and rains from May to October.
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 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.
The city has a seaport that acts as the cargo transit point between the Niger River and the Atlantic Ocean, with Nigerian Ports Authority (Delta Ports) handling the main import and export traffic.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Warri. Because international oil companies and contractors have offices in Warri, IECEx is a common reference for gas plants and refinery work. The scheme provides a certificate of conformity plus a schedule of conditions. IS-04Z1 IECEx certification is in progress, so nothing is issued and nothing should be cited as approved.
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.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
