NNPC: geography and layout
Operations are managed through strategic business units spread across Nigeria, with zonal offices in the oil-producing south and the north, so a buyer should identify which unit and location actually controls the site.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for NNPC: 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.

Working with Nigerian National Petroleum Company Limited (NNPC Ltd): sites and classified areas
The main sites and the hazardous-area types a portable device is likely to meet at this organisation.
Sites and areas
- Port Harcourt refinery (Rivers State)
- Warri refinery (Delta State)
- Kaduna refinery (Kaduna State)
- Upstream joint ventures
Classified areas

Supplier approval · NNPC
Becoming an approved supplier to NNPC
Suppliers and contractors register on the Nigerian Petroleum Exchange (NipeX), which is linked to NNPC tendering and vendor pre-qualification; local-content registration with the regulator and NCDMB is also required for work in the sector. Confirm current requirements with NNPC. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

More about NNPC that matters for portable equipment
NNPC: logistics and access
NNPC delivered its first delivered-ex-ship LNG cargo to Futtsu in Japan in June 2024, showing an export chain that runs from Nigerian gas fields through liquefaction to ships.
NNPC: background
NNPC was converted from a corporation into a limited liability company in July 2022 under the Petroleum Industry Act of 2021, so it now runs as a commercial entity rather than a ministry-style body.
NNPC: infrastructure
In September 2022 NNPC took over Oando's OVH Energy business and its 380 filling stations, adding retail fuel sites, where forecourt hazardous areas also apply.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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 NNPC. Operators in refinery units, pipelines and storage areas inspect widely separated equipment, often under demanding conditions. A handheld intrinsically safe phone allows tag scanning, photographs and defect reports inside the classified area. It would suit routine rounds and the heavy contractor activity of rehabilitation or turnaround work at refineries and upstream joint-venture sites.

Specifying an intrinsically safe mobile phone for NNPC
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 · NNPC
Frequently asked questions
Can NNPC buy the IS-04Z1 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 intrinsically safe mobile phone for NNPC cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
How does NNPC approve suppliers?
Suppliers and contractors register on the Nigerian Petroleum Exchange (NipeX), which is linked to NNPC tendering and vendor pre-qualification; local-content registration with the regulator and NCDMB is also required for work in the sector. Confirm current requirements with NNPC.
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 do I start if I want to supply phones to NNPC sites?
NNPC works through business units and joint ventures, so the entry point depends on the site. Typically you identify the unit (upstream, gas, refining or retail), contact its HSE and procurement teams, and ask for current approved-vendor requirements. Confirm the route with NNPC itself before quoting.
Are NNPC filling stations treated as hazardous areas?
Fuel dispensing areas generally have classified zones around pumps, vent pipes and tank fill points, usually Zone 1 or Zone 2 with defined radii. Local rules apply, so confirm the station's area classification and any phone-use policy with the retail operator before deploying devices.
How do heat and unreliable power affect handheld devices on site?
Heat and humidity reduce battery life, and IP68 sealing helps with rain and dust but is not explosion protection. Plan charging in safe areas, keep spare batteries, and test in local conditions. Ask each site's HSE team how portable devices may be charged and stored.
