Stanlow scale
Stanlow has been owned by Essar since 2011, was renamed EET Fuels in January 2024, and is reported at about 296,000 barrels a day.
Liverpool sits on the Mersey estuary. The Royal Seaforth and Liverpool2 terminals handle containers, liquid and dry bulk such as coal, grain and biomass, and roll-on roll-off cargo, so dust and vapour hazards arise at the quayside. Distribution partners for Liverpool and the Mersey are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Liverpool and the Mersey 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. 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 Liverpool. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Stanlow has been owned by Essar since 2011, was renamed EET Fuels in January 2024, and is reported at about 296,000 barrels a day.
EET Fuels has announced a 1.2 billion dollar decarbonisation programme, including a hydrogen-ready combined heat and power plant planned for 2027 to 2029, so project work is expected.
The city has a temperate maritime climate with mild summers, cool winters and rainfall spread fairly evenly through the year, with a record low of minus 17.6 degrees Celsius in December 2010.
Liverpool lies on the eastern side of the Mersey Estuary near the Irish Sea, 286 km north-west of London, with 507,915 residents in 2025 and a City Region population over 1.5 million.
In 2023 the UK government designated Liverpool a Freeport to encourage international commerce, which affects customs handling and site development around the port.
Liverpool hosts UK offices of shipping lines including Atlantic Container Line, Bibby Line, Hapag-Lloyd, Irish Ferries and Maersk, so marine buyers and technical managers are close together.
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 Liverpool and the Mersey. Rounds at Stanlow cover process units, tank farms, pump stations and the pipeline from Tranmere, about 24 km long. A handheld designed for intrinsic safety suits operators who log readings and photographs at each stop. Project and turnaround inspection under the decarbonisation programme could add short-term crews who also need to record findings in the area.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Liverpool and the Mersey 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.
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.
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.
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 at stanlow, marine oil terminal jetties, product pipelines and pump stations, 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 Liverpool and the Mersey.
The maritime climate brings frequent rain and sea wind, and salt air affects connectors and charging contacts. Typically devices need good ingress protection and routine cleaning, and users should check ratings against the port's rules.
Liquid bulk handling, dry bulk such as coal, grain and biomass, fuel and chemical storage and vessel operations. Vapour and dust zones can arise at jetties, silos and conveyors, so ask the terminal operator for its zone drawings and portable-device rules.
EET Fuels has announced a decarbonisation programme that includes a hydrogen-ready combined heat and power plant planned for 2027 to 2029, so project work is expected. Plans can change. A buyer should ask the operator or its contractors what equipment and marking they will require for those areas.
