Remote location
The waterway is a deep natural harbour at the western end of Wales, so contractors often travel in for turnarounds.
Airbus Broughton in the north-east employs over 6,500 people, mostly in manufacturing, and is responsible for wing assembly for most Airbus aircraft, so composites and solvent areas exist alongside heavy engineering. It hosts Valero's Pembroke refinery and the South Hook and Dragon LNG terminals, so Zone 1 work arises at process units, tank farms and gas handling areas. A hazardous area mobile phone 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.

| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |

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.
The waterway is a deep natural harbour at the western end of Wales, so contractors often travel in for turnarounds.
The Pembroke refinery began operating in 1964 and has been owned by Valero since 2011. Cardiff terminal supply by coastal tanker comes from here.
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.
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.
Wales produced 30.2 TWh of electricity in 2018 and consumed 14.9 TWh, making it a net exporter, with gas generation at Baglan Bay and wind at Cefn Croes among its mix of plant.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Wales (Milford Haven Waterway). The Milford Haven Waterway has refinery process units, LNG storage and regasification at South Hook and Dragon LNG, crude and product jetties and tank farms. Operators classify the zones under DSEAR, not SAMS. Other Welsh industry is not covered here, and Cardiff's fuel terminal is a separate, smaller location.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Wales (Milford Haven Waterway). 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 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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
