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.

Hazardous Area Mobile Phone in England
England hosts three of the UK's four operating refineries, Fawley, Stanlow and Humber, with Pembroke in Wales the fourth. Employers must identify and classify areas where explosive atmospheres may occur and avoid ignition sources, for example from unprotected equipment, in those areas. If you are specifying a hazardous area mobile phone for England, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for England: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

What England means for portable equipment
Regulation
DSEAR applies, and the UK recognises CE marking alongside UKCA for Great Britain, with the recognition period currently running to 31 December 2027.

More about England that matters for portable equipment
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.
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.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In England. England's classified areas include refinery process units, fuel terminals and tank farms, marine oil jetties and petrochemical units. The employer classifies them under DSEAR, not SAMS. Lindsey stopped refining in 2025, so its activity differs from the three operating English refineries, and terminals and gas networks add smaller classified areas elsewhere.

Specifying a hazardous area mobile phone 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 a hazardous area mobile phone 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 a hazardous area mobile phone in England cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
