Ex-Proof Mobile Phone in Edinburgh
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. 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. This page explains what to look for in an Ex-proof mobile phone for Edinburgh, Leith and the Forth, and where the IS-04Z1 stands against that list today.

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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Site conditions at Edinburgh, Leith and the Forth: what wears and what limits equipment
Leith
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.

More about Edinburgh, Leith and the Forth that matters for portable equipment
Edinburgh, Leith and the Forth: background
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, Leith and the Forth: logistics and access
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.
Edinburgh, Leith and the Forth: infrastructure
A green belt designated in 1957 surrounds the city except at the Forth shoreline, and developments such as Edinburgh Airport and the Royal Highland Showground lie within it.
Edinburgh, Leith and the Forth: climate and equipment wear
Edinburgh has a cool temperate maritime climate, known as the windy city, with prevailing south-westerly winds, rainfall spread evenly through the year, and haar, a sea fog, on easterly winds.
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 Edinburgh, Leith and the Forth. A marking check for Grangemouth would start with the process unit's zone map, since ethylene and ethane handling points towards a gas group higher than for fuels. For that reason IIC marking is the conservative choice. The IS-04Z1 target is II 2 G Ex ib IIC T4, still in certification, and the operator confirms what is needed.

Specifying an Ex-proof mobile phone for Edinburgh
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 · Edinburgh
Frequently asked questions
Can we buy an Ex-proof mobile phone in Edinburgh 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 Edinburgh cost?
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.
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 Edinburgh, Leith and the Forth would use 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.
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.
How does Edinburgh's wind and sea fog affect equipment used outdoors?
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.
Do UK explosive-atmosphere rules apply in Scotland?
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.
What is changing at Grangemouth that affects buyers?
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.
