Ex-Proof Smartphone in Lagos
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. The Dangote refinery at Lekki is designed for 650,000 barrels a day, so refining, storage and loading are the main hazardous areas. If you are specifying an Ex-proof smartphone for Lagos, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

What Lagos means for portable equipment
Port-led economy
Apapa is the oldest and largest port complex and handles more than half of Nigeria's maritime trade.
Field notes · Lagos
More about Lagos that matters for portable equipment
Lagos: geography and layout
Lagos is built on lands separated by creeks around the south-west mouth of the Lagos Lagoon and protected from the Atlantic by barrier islands and sand spits, a humid coastal setting that is hard on equipment.
Lagos: logistics and access
Lagos has three ports, at Apapa, Tin Can Island and the Lekki deep-sea port, plus four expressways and a standard-gauge rail link to Abeokuta and Ibadan, and handles 88% of Nigeria's exports.
Lagos: infrastructure
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.
Lagos: people and language
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.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Lagos. At the Dangote refinery, a fuel or LPG storage site or a tanker jetty, a marking check reads zone, gas group and temperature class on the label and compares each with the operator's classification. LPG and fuel vapours fall within common gas groups, and the IS-04Z1 target marking II 2 G Ex ib IIC T4 would be compared with them.

Specifying an Ex-proof smartphone for Lagos
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Lagos
Frequently asked questions
Can we buy an Ex-proof smartphone in Lagos today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an Ex-proof smartphone in Lagos cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Lagos would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
Where are the main hazardous-area sites in Lagos?
The Dangote refinery at Lekki is the largest, and the port areas of Apapa, Tin Can Island and Lekki handle fuel and bulk cargo. Shipyards, breweries and pharmaceutical plants also have classified areas. Confirm each site's zone classification and device rules with its operator.
How should I plan equipment logistics to Lagos?
Most imported equipment arrives through Apapa, Tin Can Island, Lekki or the international airport, and port congestion and customs clearance can add time. Agree a clearing agent, check radio-device import rules and allow buffer time before any shutdown or commissioning date.
Which Nigerian portal do oil and gas suppliers use?
Oil and gas suppliers often register on the NCDMB-managed NOGIC-JQS portal, and large operators also run their own formal vendor registration. Check which applies to your route to market. Confirm current requirements with the site operator or its procurement team.
