Intrinsically Safe Smartphone Distributor in England
England hosts three of the UK's four operating refineries, Fawley, Stanlow and Humber, with Pembroke in Wales the fourth. Major-hazard sites fall under the Control of Major Accident Hazards Regulations 2015, with HSE publishing guidance and public information on establishments covered, so top-tier and lower-tier sites follow a further regime. Distribution partners for England are being identified ahead of the Q4 2026 launch of the IS-04Z1.

WhereEngland
Short answer. England 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

More about England that matters for portable equipment
England: rules and approvals
COMAH 2015 is enforced by a joint Competent Authority: HSE, or the Office for Nuclear Regulation for nuclear sites, working with the Environment Agency in England, Natural Resources Wales or SEPA in Scotland.
England: rules and approvals
Employers must identify and classify areas where explosive atmospheres may occur and avoid ignition sources, for example from unprotected equipment, in those areas.
England: industry on the ground
HSE lists dangerous substances as including solvents, paints, varnishes, flammable gases such as LPG, dusts from machining, sanding and foodstuffs, pressurised gases and substances corrosive to metal.
England: people and language
DSEAR duties fall on employers and the self-employed and also protect members of the public who may be put at risk by work activity, so contractors share responsibility with site owners.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In England. Operators at Fawley on Southampton Water, Stanlow in Cheshire and the Humber site make rounds over process units, tank farms and jetties. A handheld designed for intrinsic safety suits those rounds and turnaround inspection, since photographs, readings and permits can be handled at the point of work without leaving the classified area.
The route · distribution
Distributing the IS-04Z1 in England
A distributor for England would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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 England.
- 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 · England
Frequently asked questions
Can we buy an intrinsically safe smartphone in England 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 intrinsically safe smartphone in England cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Which areas at England would use it?
Likely candidates are refinery process units, fuel terminals and tank farms, marine oil jetties, petrochemical units. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for England?
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 England.
Does COMAH affect which equipment I can use?
COMAH applies to major-hazard sites such as large chemical and fuel storage establishments and adds management duties on top of DSEAR. Each operator typically sets its own rules for portable electronics, so check the site's permit and induction requirements.
Which regulations govern portable electronics in explosive atmospheres in England?
The Dangerous Substances and Explosive Atmospheres Regulations 2002 require employers to classify hazardous areas and avoid ignition sources. Equipment choice is then based on the zone, gas group and temperature class, so ask the site for its hazardous-area register.
Does the UK accept CE marking or only UKCA?
Guidance says CE marking is recognised alongside UKCA for Great Britain, with the recognition period currently running to 31 December 2027, and that date may change. Buyers should check the current gov.uk guidance and ask their operator's procurement team what evidence they require.
