Tranmere supply
Crude oil arrives at Tranmere on the Mersey and travels to Stanlow by pipeline of about 24 km.

Intrinsically Safe Mobile Phone in Liverpool
Liverpool sits on the Mersey estuary. The Stanlow refinery at Ellesmere Port, on the Manchester Ship Canal, receives crude through the Tranmere Oil Terminal on the Mersey, so Zone 1 areas are found at the refinery, jetties and pipelines around the estuary rather than in the city. This page explains what to look for in an intrinsically safe mobile phone for Liverpool and the Mersey, and where the IS-04Z1 stands against that list today.

Liverpool and the Mersey: rules and approvals
In 2023 the UK government designated Liverpool a Freeport to encourage international commerce, which affects customs handling and site development around the port.
Liverpool and the Mersey: who works there
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.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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.

Questions · Liverpool
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Liverpool today?
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.
What does an intrinsically safe mobile phone in Liverpool 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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
Which areas at Liverpool and the Mersey would use it?
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.
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.
Does the Freeport status affect equipment imports into Liverpool?
It can change customs processes for goods moved within the Freeport area, but product-safety and radio rules still apply. Confirm treatment of electronic devices with your customs agent and the Freeport operator before shipping.
Are UK explosive-atmosphere rules the same in Liverpool as elsewhere in Britain?
Yes. The Dangerous Substances and Explosive Atmospheres Regulations apply across Great Britain, with HSE as regulator. Port operators and tenants must classify areas and control ignition sources, so ask for the site's hazardous-area register before using electronics.
Where are the hazardous areas near Liverpool?
Mainly at the Stanlow refinery in Ellesmere Port on the Manchester Ship Canal and at the Tranmere Oil Terminal on the Mersey, which supplies crude to Stanlow by a pipeline of about 24 km. The city itself is not the classified site. Check zone details with the operator.
