Fuel terminal
Valero imports petrol, ultra low sulphur diesel, biofuels and heating fuels through Cardiff for distribution to the south Wales market.
Cardiff is the capital of Wales. Its Roath Dock, run by Associated British Ports, has a 12-acre fuel storage and distribution terminal occupied by Valero, fed by coastal tankers. Zone 1 work arises at fuel handling and storage, while Wales' refining is at Pembroke rather than Cardiff. This page explains what to look for in an ATEX and IECEx mobile phone for Cardiff and Roath Dock, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Cardiff and Roath Dock: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Cardiff. 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.
Valero imports petrol, ultra low sulphur diesel, biofuels and heating fuels through Cardiff for distribution to the south Wales market.
Fuel arrives by coastal tanker from Valero's Pembroke refinery, a sea voyage of roughly 100 miles.
In 2021 about 12.2 percent of residents aged three and over could speak Welsh, double the 1991 share, so bilingual signage and Welsh-language materials are common in public and some workplace settings.
Rival docks at Barry were promoted in the 1880s because they were accessible in all tides, which shows how strongly tidal range on the Severn Estuary and Bristol Channel shapes port operations.
Cardiff has a maritime climate with an average annual temperature of about 11 degrees Celsius and about 1,200 mm of rain on 153 days a year, with more than 100 mm a month from October to January.
Cardiff Docks once had almost 11 km of quayage and still handle containers, steel, forest products and dry and liquid bulks, though coal exports built the port in the 19th century.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Cardiff and Roath Dock. An HSE-minded reviewer in Cardiff would ask for ATEX-style evidence because the employer's DSEAR assessment drives equipment choice at the Roath Dock fuel terminal. A dual ATEX and IECEx route, both in progress for SAMS, would also help visiting inspection contractors who carry international paperwork. Neither certificate has been issued, and nothing should be specified from this page.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are fuel storage and distribution terminal, marine jetty and tanker discharge, road tanker loading. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
The maritime climate is mild but wet, with rain on about 153 days a year and persistent wind from the Bristol Channel. Typically users want good water ingress protection and routine drying and cleaning of connectors, and should check the device rating against the site.
Not mainly. The city is Wales's commercial and administrative centre, and the old steelworks closed in 1978, though the wider Severn Estuary and South Wales coast host fuel, energy and processing sites. Confirm the operator and site classification for the actual place you will work.
Under DSEAR, the employer assesses hazardous zones and chooses suitable equipment, so the terminal operator and its safety adviser decide. Valero occupies the terminal and Associated British Ports runs the dock. Confirm requirements with the site operator before specifying any handheld device.
