Humid tropics
Annual rainfall is about 2,770 mm, with a dry season from November to April and rains from May to October.
The dry season runs from about November to April and brings the harmattan, a dusty haze on the north-east trade winds, while the rainy season spans May to October with a short drier spell in August. Chevron's Escravos gas plant and gas-to-liquids plant lie in the western Niger Delta. Distribution partners for Warri are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Warri has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
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.
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.
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.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Warri. At the refinery and petrochemicals complex and at gas-to-liquids facilities, explosion-proof is the working word for approved gear. Flameproof Ex d suits fixed equipment in strong housings, whereas a phone carried through gas plants and jetty areas suits intrinsic safety, the principle on which the IS-04Z1 is designed.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Warri. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Warri.
Rain falls from about May to October with annual totals near 2,770 mm, so expect sustained humidity. Choose devices with a sealed housing and a strap or holster, keep spare batteries dry, and check the operator's induction rules about devices in wet, classified outdoor areas.
Typically yes. The dry-season harmattan carries fine dust that can clog ports, speaker grilles and cooling paths, so sealed enclosures (dust-tight ratings) and routine cleaning matter. Confirm the dust and ingress requirements with the site operator before specifying equipment.
The refinery has been shut and restarted repeatedly since 2025, and NNPC signed a memorandum with Chinese firms in April 2026 on restart plans. Check current status first, before planning any visit or quote. Confirm it with the site operator.
