Refinery closed
Petroineos ended crude processing at the Grangemouth refinery in 2025, and the site is becoming a fuels import, storage and distribution terminal.
Edinburgh lies on the south shore of the Firth of Forth in Scotland's Central Belt, with 506,520 residents in 2020 and a wider metropolitan area of 912,490. Its Port of Leith is being developed for offshore wind, while the Grangemouth petrochemical complex lies further up the Forth, where hazardous-area demand is concentrated. If you are specifying an IECEx mobile phone for Edinburgh, Leith and the Forth, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Edinburgh, Leith and the Forth: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Edinburgh. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
Petroineos ended crude processing at the Grangemouth refinery in 2025, and the site is becoming a fuels import, storage and distribution terminal.
In December 2024 Forth Ports announced a 50 million pound private investment at the Port of Leith after winning its largest offshore wind contract, for the 1.1 GW Inch Cape project. Foundations are handled at Leith.
The city has long been a centre of education in medicine, law, science and engineering, which supports a trained workforce for the professional and technical services based there.
The city is the United Kingdom's second-largest financial and administrative centre after London, and a financial district has grown west of the castle since the 1990s.
Traditional industries of printing, brewing and distilling grew in the 19th century alongside rubber and engineering works, so the city has long had solvent, grain-dust and spirit-storage sites.
Edinburgh Airport lies 9 km west of the city centre just off the M8 and M9 motorways; it is Scotland's busiest, with 15.8 million passengers in 2024 and over 150 international destinations.
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 Edinburgh, Leith and the Forth. Leith's offshore wind foundation handling and Grangemouth's petrochemical operations attract international contractors who often work to IECEx documentation. The target is a certificate of conformity and a schedule of conditions that a project engineer can read against the specific area. That paperwork does not exist yet and must be confirmed once issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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 port and offshore wind foundation handling, petrochemical process units at grangemouth, fuel import and storage terminal at grangemouth, ethane import and storage. 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.
Edinburgh is known for wind, and easterly haar brings damp sea fog, so devices used on the waterfront need good ingress protection and cleaning. Typically workers also note reduced visibility, so check screens, torches and alarms against site conditions.
Yes. The Dangerous Substances and Explosive Atmospheres Regulations apply across Great Britain, and the Health and Safety Executive enforces them with local authorities. Employers must classify areas and control ignition sources, so ask sites for their hazardous-area records.
Petroineos ended crude processing at the Grangemouth refinery in 2025, and the site is becoming a fuels import, storage and distribution terminal. The adjacent INEOS complex still operates the UK's last ethylene cracker. Contractor needs may therefore differ from a few years ago, so ask the operator for current requirements.
