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.
Scotland has a long oil, gas and petrochemical base. Hazardous-area work arises at the Grangemouth petrochemical complex on the Firth of Forth, the Mossmorran site in Fife and the St Fergus gas terminal in Aberdeenshire. Several of these sites are in transition. An IECEx mobile phone distributor in Scotland would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Scotland 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Scotland. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Shell's Fife NGL plant separates natural gas liquids. ExxonMobil's Fife Ethylene Plant ceased production in February 2026 and is due to be decommissioned, so activity there is shifting to closure work.
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.
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.
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.
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.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Scotland. Scotland's large process and gas sites attract international EPCs, turnaround specialists and, at Mossmorran, decommissioning contractors who may arrive with IECEx documentation. The aim is a certificate of conformity and a schedule of conditions that an engineer can read against a specific area. At present it is still in progress.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Scotland 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.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
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 Scotland.
Offshore and coastal sites face wind, rain, salt spray and cold, and winter weather can disrupt crew changes. For handheld devices check ingress protection, corrosion resistance, glove-friendly controls and low-temperature battery behaviour, and ask the platform or terminal for its own requirements.
Aberdeen and the north-east are the centre of offshore oil and gas support, with other activity at the Grangemouth industrial area on the Firth of Forth, east-coast and Shetland terminals, shipyards, distilleries and offshore wind bases. Zoning is site-specific, so ask each operator for classification drawings.
The Grangemouth refinery stopped processing crude in 2025 and is becoming a fuels import terminal, and ExxonMobil's Fife Ethylene Plant ceased production in February 2026 and is due to be decommissioned. Work may therefore shift towards closure and conversion, so ask operators which contractors and requirements apply.
