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.

Ex-Proof Mobile Phone Distributor 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. An Ex-proof mobile phone distributor in England would carry the IS-04Z1 to these buyers once certification completes.

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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

More about England that matters for portable equipment
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.
England: rules and approvals
In Great Britain, the 2016 EPS Regulations implement the ATEX equipment directive, and the UK government has extended recognition of goods meeting EU requirements, including CE marking, indefinitely beyond 2024 for many products, in force from 1 October 2024.
England: rules and approvals
The Dangerous Substances and Explosive Atmospheres Regulations 2002, known as DSEAR, require employers to control risks to safety from fire, explosion and substances corrosive to metals in the workplace.
England: who works there
Employers must also prepare plans for accidents and emergencies and make sure staff are informed and trained to deal with dangerous-substance risks, which is why site inductions usually cover equipment rules.
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 England. A marking check at an English refinery would compare each area's classification with the equipment label, covering zone, gas group and temperature class. Petrochemical units may call for IIC, whereas fuel areas are usually a lower group. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, pending certification, so confirm it against the operator's list.
The route · distribution
Distributing the IS-04Z1 in England
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for England 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 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 Ex-proof mobile phone in England today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an Ex-proof mobile phone 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 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 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.
