United Kingdom: rules and approvals
Great Britain applies SI 2016 No. 1107, the UK version of the ATEX rules, so equipment for explosive atmospheres is assessed by UK approved bodies and carries UKCA marking and a body number.

Explosion-Proof Mobile Phone Distributor in United Kingdom
The IS-04Z1 is an intrinsically safe Android smartphone designed for Zone 1 and Zone 21 work, from a North Sea deck to a gas governor kiosk at the end of a street. Historically most UK gas came from Morecambe Bay and the Southern North Sea off East Anglia and Lincolnshire, both now in decline, while oil comes mainly from the Central Graben of the North Sea. Distribution partners for United Kingdom are being identified ahead of the Q4 2026 launch of the IS-04Z1.

United Kingdom: industry on the ground
Around 39 billion barrels of oil equivalent have been extracted from the UK Continental Shelf over four decades, and Brent crude from the British North Sea remains a major international price benchmark.
United Kingdom: rules and approvals
The UK government has legislated to keep recognising CE marking alongside UKCA for a range of product regulations, so check whether the route applies to your product category.
United Kingdom: industry on the ground
UK crude oil and condensate production had fallen to about 630,000 barrels a day by 2024, so much of the current work is maintenance, life extension and decommissioning of mature installations.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In United Kingdom. Explosion-proof is the everyday phrase, but a UK installation holds very different areas, from offshore platforms to St Fergus and Sullom Voe, and gas networks inland. Flameproof Ex d suits fixed enclosures, while the IS-04Z1 uses intrinsic safety to limit the energy of a handheld, which suits permit-controlled entries.
The route · distribution
Distributing the IS-04Z1 in United Kingdom
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for United Kingdom 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.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in United Kingdom.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · United Kingdom
Frequently asked questions
Can we buy an explosion proof mobile phone in United Kingdom today?
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.
What does an explosion proof mobile phone in United Kingdom 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which sites in United Kingdom does this cover?
The market guide for United Kingdom covers Aberdeen, St Fergus, Sullom Voe, Grangemouth, among others. Site-level pages are linked below.
How do I become a SAMS distributor for United Kingdom?
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 United Kingdom.
What does DSEAR mean for choosing a phone for UK plants?
DSEAR places duties on employers to classify areas where explosive atmospheres may occur and to avoid ignition sources from unprotected equipment. A site will therefore expect devices used in classified areas to be suitable for the zone, gas group and temperature class stated in its area classification records.
Is CE-marked ATEX equipment accepted in Great Britain?
Yes. Since 1 October 2024 CE marking has been recognised in Great Britain without an end date, so an ATEX-certified product can be sold there without UKCA, although a UKCA route with a UK approved body also exists. Northern Ireland still requires CE. Check the current rules before shipping.
How does the IS-04Z1 cope with patchy coverage on a UK platform or rural site?
It combines 4G LTE, Wi-Fi and four-constellation GNSS to hold a position and a connection where one network is not enough. Actual coverage depends on the site, so test the unit on your own route before relying on it.
