The Dangote refinery at Lekki reached full refining capacity in February 2026 and is the largest employer in Lagos, so it is the best-known large classified-area site in the city. The Dangote refinery at Lekki is designed for 650,000 barrels a day, so refining, storage and loading are the main hazardous areas. Distribution partners for Lagos are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Lagos 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Lagos: Refinery process units, Fuel and LPG storage, Port tanker jetties and loading | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Lagos. 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.
A wet season from May to October and coastal humidity apply.
Apapa is the oldest and largest port complex and handles more than half of Nigeria's maritime trade.
The Lagos Free Zone covers 830 hectares about 60 km east of Lagos city, is integrated with the Lekki Deep Sea Port, and counts Raffles Oil among its first companies.
The refinery's main contractor was China National Chemical Engineering Company, with Engineers India providing project management, so international EPC contractors and mixed-language teams are typical on large Lagos projects.
Other major employers include two breweries, three major shipyards and numerous pharmaceutical companies, so flammable solvents, fuels and dust occur beyond oil and gas.
Dangote refinery owner has announced an expansion to 1.4 million barrels a day, estimated at 14.3 billion US dollars and expected to be completed by 2029, which implies years of construction and commissioning work.
“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 Lagos. At a refinery or tanker jetty in Lagos, explosion-proof is the working phrase for any approved gear. Flameproof Ex d covers fixed equipment in strong housings, while a handheld for loading and storage rounds uses intrinsic safety. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Lagos. 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, fuel and lpg storage, port tanker jetties and loading. 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 Lagos.
International and local operators commonly work to IEC 60079 and ask for IECEx or ATEX paperwork, but each site sets its own approval process. Ask the operator's HSE and procurement teams for the approved equipment list and a sample documentation pack before you ship devices.
Yes, heat, humidity and salt air stress seals, ports and batteries. Check the maximum ambient temperature on the certificate, the water and dust ingress rating and the condition of charging contacts. Regular cleaning and spare batteries are typically worthwhile for long outdoor shifts.
Dense traffic across the metropolitan area can slow deliveries, so lead times need extra margin. Agree delivery windows with the facility, plan alternative routes to ports and the Lekki area, and keep spare devices available for critical shifts.
