Power stations
Ballylumford, owned by EP UK Investments since 2019, is the region's largest power station and runs on natural gas. Coolkeeragh near Derry is a 400 MW gas-fired plant owned by ESB.

Intrinsically Safe Mobile Phone in Northern Ireland
Northern Ireland is a UK region with gas-fired power stations, the Scotland-Northern Ireland gas pipeline landing at Islandmagee and a proposed gas storage cavern project there. Zone 1 work arises at power stations, gas transmission assets and fuel storage. If you are specifying an intrinsically safe mobile phone for Northern Ireland, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

WhereNorthern Ireland
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Northern Ireland: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

More about Northern Ireland that matters for portable equipment
Northern Ireland: industry on the ground
The Harland and Wolff shipyard in the Port of Belfast has two of Europe's largest drydocks, with a main dock of 556 m by 93 m, and is licensed for vessel repair and open grit blasting.
Northern Ireland: industry on the ground
Northern Ireland was self-sufficient in food production by 2021 and exported more than half of its meat and crops, so food plants with dust, ammonia refrigeration and flour or feed handling are common.
Northern Ireland: infrastructure
Gas for Greater Belfast arrives through the 24-inch Scotland-Northern Ireland pipeline, and a north-west pipeline from Carrickfergus to Derry opened in November 2004, so gas networks and compressor sites sit across the east and north-west.
Northern Ireland: people and language
Unemployment was about 1.6% in early 2025, so qualified engineering and maintenance contractors can be hard to book at short notice during shutdown periods.
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 Northern Ireland. Rounds at Ballylumford or Coolkeeragh include fuel gas lines, pressure reduction skids and plant checks, and the gas pipeline from Islandmagee has its own inspection routes. A handheld designed for intrinsic safety lets staff record readings and photographs where they work, rather than walking to a safe area for every note.

Specifying an intrinsically safe mobile phone for Northern Ireland
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 · Northern Ireland
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Northern Ireland 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 in Northern Ireland 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 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.
Which areas at Northern Ireland would use it?
Likely candidates are gas-fired power station fuel systems, gas transmission pipeline assets, gas pressure reduction sites, fuel storage. 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.
Is crossing the Irish Sea a logistics issue for equipment supply?
Goods moving between Great Britain and Northern Ireland pass through post-Brexit customs arrangements, which can add paperwork and lead time. For urgent site equipment, plan stock holding in Northern Ireland or the Republic and confirm the current import documentation with your freight forwarder.
How does the damp maritime climate affect phone selection?
Northern Ireland has a mild but wet and windy climate, with frequent rain and salt air near the coast, so sealing, corrosion resistance and condensation tolerance matter more than extreme temperature ratings. Check ingress protection and gasket quality, and ask the site about its own requirements.
Which marking applies to equipment in Northern Ireland?
Under the Windsor Framework, relevant EU product rules apply in Northern Ireland, so equipment is typically CE marked, with UKNI added where a UK notified body is used. Because rules can change, confirm the current position with the site operator and HSENI guidance.
