Hazardous Area Mobile Phone in Wales
The Milford Haven Waterway in Pembrokeshire is Wales' largest port and a major energy hub. Two LNG terminals, South Hook on a former refinery site and Dragon LNG on a former Gulf refinery site, were built from 2006 and could eventually supply about 25% of the UK's gas needs. If you are specifying a hazardous area mobile phone for Wales (Milford Haven Waterway), this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Wales (Milford Haven Waterway): industry on the ground
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.
Wales (Milford Haven Waterway): industry on the ground
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.
Wales (Milford Haven Waterway): industry on the ground
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.
Wales (Milford Haven Waterway): infrastructure
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.
The term · hazardous area
What “hazardous area” means for a smartphone
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.

Questions · Wales
Frequently asked questions
Can we buy a hazardous area mobile phone in Wales 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 a hazardous area mobile phone in Wales cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Which hazardous areas is the IS-04Z1 designed for?
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.
Which areas at Wales (Milford Haven Waterway) would use 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.
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.
Do Welsh sites follow the same Ex marking rules as the rest of Great Britain?
Yes, Wales is within Great Britain's product rules, where equipment for explosive atmospheres is normally supplied with UKCA marking and CE-marked ATEX equipment has been widely accepted under transitional arrangements. Check the current position and any site-specific rules with the operator before supplying handheld devices.
How does the Welsh climate affect devices used outdoors?
Wales is mild but wet and windy, with salt spray at coastal terminals such as Milford Haven. Ingress protection, corrosion resistance and condensation tolerance are more important than extreme temperature ratings. Ask the site about its own environmental requirements for portable electronics.
What hazardous-area work is there in Wales?
The Milford Haven Waterway in Pembrokeshire hosts Valero's Pembroke refinery, which began operating in 1964, and the South Hook and Dragon LNG terminals. Zone 1 work arises at process units, tank farms and gas handling areas. Confirm requirements with each operator's HSE and procurement teams.
