LNG
South Hook, opened in 2009 with five storage tanks, is described as Europe's largest LNG terminal. With Dragon LNG, the two terminals can provide up to a quarter of UK gas demand.
The Milford Haven Waterway in Pembrokeshire is Wales' largest port and a major energy hub. By 2018 Wales generated over 3,864 MW of renewable energy from 68,728 projects, and the Welsh Government set a target of meeting 70% of electricity demand from Welsh renewables by 2030. An intrinsically safe smartphone distributor in Wales (Milford Haven Waterway) would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Wales (Milford Haven Waterway) 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | Wales (Milford Haven Waterway): Crude and product jetties, Tank farms, Refinery process units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Wales. 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.
South Hook, opened in 2009 with five storage tanks, is described as Europe's largest LNG terminal. With Dragon LNG, the two terminals can provide up to a quarter of UK gas demand.
The waterway is a deep natural harbour at the western end of Wales, so contractors often travel in for turnarounds.
Oil refining at Milford Haven began with the first oil terminal and refinery in 1960, and the waterway still carries the jetties, oil terminals and shore processing facilities of the oil and power industries.
Regasified LNG leaves Milford Haven through National Grid's South Wales Gas Pipeline to a distribution point at Tirley in Gloucestershire, so pipeline and compression sites run across south Wales.
Milford Haven is the largest port in Wales and the third-largest in the United Kingdom, run by the Milford Haven Port Authority as a trust port that manages Milford Docks, Milford Marina and Pembroke Port.
In 2012 the Milford waterway was announced as an Enterprise Zone because of its importance to the energy sector, and parts of it lie within the Pembrokeshire Coast National Park with protected sites.
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 Wales (Milford Haven Waterway). Rounds at Pembroke cover process units and tank farms, while the LNG terminals involve storage tanks, regasification areas and jetty operations. A handheld designed for intrinsic safety suits those inspections, and also turnaround work where contractors travel in and need to record findings in the area.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Wales (Milford Haven Waterway) yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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.
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, lng storage and regasification, crude and product jetties, tank farms. 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 Wales (Milford Haven Waterway).
English is normally sufficient for industrial site documentation in Wales, although some public-sector bodies use bilingual material. For plant equipment, operators typically require English manuals and safety information, but confirm the expectation with each site's procurement team.
The Milford Haven Waterway in Pembrokeshire is the best-known cluster, with oil and LNG terminals, jetties and processing plants, and there are gas pipelines, power stations, chemical works and fuel depots elsewhere in south and north Wales. Zoning is site-specific, so ask each operator for area drawings.
The waterway lies at the western end of Wales, so contractors often travel in for turnarounds, and equipment must arrive and be signed in on schedule. Plan delivery, charging and device enrolment before the work starts, and ask each operator how contractor equipment is checked on arrival.
