St Fergus
The terminal handles roughly a quarter of Britain's gas and sends natural gas liquids to Mossmorran. It is owned by North Sea Midstream Partners, with Shell, Esso and others as tenants.

Ex-Proof Mobile Phone in Scotland
A 58-mile pipeline from the Finnart oil terminal on Loch Long to Grangemouth has operated since the 1950s, and the Kinneil terminal stabilised North Sea Forties crude from 1975. Several of these sites are in transition. This page explains what to look for in an Ex-proof mobile phone for Scotland, and where the IS-04Z1 stands against that list today.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Scotland: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

What Scotland means for portable equipment
Grangemouth
The refinery stopped processing crude in 2025 and is becoming a fuels import terminal, while the adjacent INEOS complex continues to run the UK's last operating ethylene cracker.
Field notes · Scotland
More about Scotland that matters for portable equipment
Scotland: industry on the ground
Scottish waters hold the largest oil resources in Western Europe; oil was discovered in the North Sea in 1966 and the first year of full production was 1976.
Scotland: projects and investment
Hydrocarbon production is expected to fall to about a third of 2019 levels by 2035, and a global decommissioning market of around 67 billion pounds over ten years is forecast, so abandonment work is growing.
Scotland: industry on the ground
Shipbuilding remains significant, generating 403 million pounds of gross value added in 2022, alongside oil and gas, food and drink, energy and manufacturing among Scotland's primary industries.
Scotland: rules and approvals
The North Sea Transition Authority regulates licensing, and OPRED regulates environmental and decommissioning activity for offshore oil and gas, so offshore work answers to UK regulators rather than Scottish bodies.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Scotland. A marking check would differ between sites. Ethylene and natural gas liquids handling at Grangemouth and Mossmorran suggests conservative IIC marking, while St Fergus handles natural gas. The operator's zone documents govern. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, still pending certification.

Specifying an Ex-proof mobile phone for Scotland
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Scotland
Frequently asked questions
Can we buy an Ex-proof mobile phone in Scotland 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 Ex-proof mobile phone in Scotland cost?
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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Scotland would use it?
Likely candidates are petrochemical process units, natural gas liquids plant, gas terminals, fuel import and storage terminal. 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.
Which marking should Ex phones carry for UK offshore work?
Offshore installations in the UK sector normally expect equipment certified for explosive atmospheres under UK rules, and CE-marked ATEX equipment has been widely accepted under transitional arrangements. Operators also add their own policies, so confirm the accepted marking and any site-specific approvals with the duty holder.
Is decommissioning work a growing user of Ex equipment in Scotland?
Decommissioning of ageing North Sea installations is forecast to grow as production declines, and it involves cleaning, cutting and removal of hydrocarbon systems in classified areas. Teams often need portable communications that are certified for the area, so confirm requirements with the operator or decommissioning contractor.
Which Scottish sites are the main hazardous-area locations?
The Grangemouth petrochemical complex on the Firth of Forth, Mossmorran in Fife and the St Fergus gas terminal in Aberdeenshire. Several are in transition, so activity may be shifting. Confirm current requirements with the site operator before planning equipment.
