Many facilities are in low-lying creek and swamp areas reached by road or boat.
Port Harcourt is the main city of Rivers State and Nigeria's chief oil-refining city, with the Port Harcourt Refining Company complex at Eleme and seaports at Onne and the city wharf. Oil companies with offices in Port Harcourt include Shell, Chevron and Agip, so contractors and suppliers often deal with international operator procedures in the city. An intrinsically safe smartphone distributor in Port Harcourt would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Port Harcourt 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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Port Harcourt. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Many facilities are in low-lying creek and swamp areas reached by road or boat.
A tropical monsoon climate brings very heavy rain, with an average of about 367 mm in September.
Onne, in Eleme, hosts the Onne Oil and Gas Free Zone, a main offshore support base where supply vessels call every week and where Shell and other operators lease berths and shore facilities.
The Port Harcourt Refining Company at Alesa Eleme runs two refineries, a 1965 plant of 60,000 barrels per stream day and a 1989 plant of 150,000, giving 210,000 barrels per stream day combined.
Shell-BP found oil at Oloibiri in 1956 and discovered the Afam and Bomu wells in Ogoni territory in the same period, so the region around Port Harcourt has among Nigeria's oldest producing areas.
Port Harcourt was founded in 1912 to export coal from Enugu, 243 km to the north, over the Eastern Line railway, so it was a port city long before oil.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Port Harcourt. Many facilities are in low-lying creek and swamp areas reached by road or boat, so crews cover long routes and cannot easily return to a safe area. A handheld that is intrinsically safe allows photos, permits and reports at the point of work. That is the purpose of the IS-04Z1 design, subject to certification.
A distributor for Port Harcourt would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are refinery process units, flow stations and gas plants, export and port facilities, pipeline and pumping facilities. 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 Port Harcourt.
It is hot, humid and wet for much of the year, so check the maximum ambient temperature on the certificate, the water ingress rating and sealing of ports and charging contacts. Corrosion from humid, salt-laden air is common, so choose devices with robust seals and clean them regularly.
International operators commonly work to IEC 60079 and ask for IECEx or ATEX certification, but each company has its own approval and registration route. Ask the procurement and HSE teams for the approved equipment list, and prepare certificates, marking photos and instructions for the submission.
The old refinery reopened in November 2024 but was shut for maintenance in May 2025, and status changes often. Check its current operating state before planning visits or quoting. Confirm the position with the site operator or Port Harcourt Refining Company.
