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 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. 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. Distribution partners for Edinburgh, Leith and the Forth are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Edinburgh, Leith and the Forth 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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. 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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
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.
Leith has been Edinburgh's port since at least the royal charter of 1329, and it retains a separate identity at the mouth of the Water of Leith, though the last shipyard there has closed.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Edinburgh, Leith and the Forth. Edinburgh itself has few classified areas. The hazardous-area demand is at Grangemouth, about 25 miles away on the Forth: petrochemical process units, ethane import and storage, and a fuel import terminal. The site operators classify these areas under DSEAR, not SAMS. Leith port work is mainly foundations handling rather than classified process plant.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Edinburgh, Leith and the Forth. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
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 Edinburgh, Leith and the Forth.
Mostly it is an administrative and financial centre, with limited heavy industry. Whisky, brewing, fuel storage and port activity exist in and around the Forth, and larger process sites are elsewhere in Scotland, so confirm the site and operator before assuming a classification.
Edinburgh Airport lies within the green belt and the city has rail links across the Central Belt, so travel from other UK and European cities is straightforward. Plan equipment delivery by road freight and confirm gate procedures with each site.
Mostly no. The city has few classified areas, and the Port of Leith is being developed for offshore wind foundation handling. The petrochemical complex and fuel import terminal are at Grangemouth, up the Forth. Confirm with the site operator which area a given task falls into before choosing equipment.
