Operating refineries
Reported capacities are roughly 270,000 barrels a day at ExxonMobil's Fawley on Southampton Water, about 296,000 at Stanlow in Cheshire and about 221,000 at Phillips 66's Humber site in North Lincolnshire.

Industrial Smartphone in England
England hosts three of the UK's four operating refineries, Fawley, Stanlow and Humber, with Pembroke in Wales the fourth. Classified areas also occur at fuel terminals, gas networks and chemical sites. Lindsey stopped refining in 2025. This page explains what to look for in an industrial smartphone for England, and where the IS-04Z1 stands against that list today.

Site conditions at England: what wears and what limits equipment
Lindsey
Lindsey closed in 2025 after owner Prax became insolvent; Phillips 66 agreed in January 2026 to acquire assets but said it will not restart it as a standalone refinery.
Field notes · England
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: projects and investment
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.
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.
The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In England. Large English sites run contractor fleets across shifts and turnarounds, so enrolment of devices in an MDM or EMM system and a clear return process are essential. Operators often have their own contractor approval and IT policies, which may restrict apps or require device lock-down. Handsets would be charged in safe areas away from process units.

Specifying an industrial smartphone for England
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 · England
Frequently asked questions
Can we buy an industrial 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 industrial smartphone in England 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 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still 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.
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.
Who enforces explosive-atmosphere rules in England?
The Health and Safety Executive, and in some premises local authorities, enforce DSEAR. They expect employers to carry out a risk assessment, classify areas and control ignition sources. Ask your client which assessments and records apply to your work.
Do dust risks count as explosive atmospheres in England?
Yes. HSE lists dusts from machining, sanding and foodstuffs among dangerous substances, so combustible dust areas can be classified in the same way as gas areas. Check whether your task is near flour, wood, metal or grain handling and ask for the zone classification.
Which English sites are the main hazardous-area demand?
England hosts three of the UK's four operating refineries: Fawley, Stanlow and Humber. Fuel terminals, gas networks and chemical sites also contain classified areas. Lindsey stopped refining in 2025. Each operator assesses its own zones, so confirm requirements with the site operator for the specific site.
