West Thurrock
The terminal at West Thurrock, Essex, with about 86 tanks for petroleum products, chemicals and liquefied gas, was acquired in 2016 by Navigator Terminals, a Greenergy and Macquarie joint venture.

Explosion-Proof Smartphone in London
London has no refinery, but Thames-side fuel terminals supply the capital: Thames Oilport on the former Coryton refinery site and the large West Thurrock terminal in Essex. London stands on the River Thames at the head of a 50 mile tidal estuary down to the North Sea, with 9.14 million residents in 2025 and a metropolitan area of 15.4 million. This page explains what to look for in an explosion proof smartphone for London and the Thames, and where the IS-04Z1 stands against that list today.

What London and the Thames means for portable equipment
Estuary location
The terminals are on the Thames estuary in Essex, not inside Greater London, so site access involves road transfers from the capital.
Field notes · London and the Thames
More about London and the Thames that matters for portable equipment
London and the Thames: people and language
London's diverse communities speak over 300 languages, so site teams are multilingual, though safety documentation is usually in English.
London and the Thames: climate and equipment wear
London has a temperate oceanic climate with about 600 mm of rain a year but 109.6 rainy days, so showers are frequent although annual totals are low.
London and the Thames: rules and approvals
The Port of London Authority has jurisdiction on the tidal Thames, and the London Fire Brigade is the statutory fire and rescue service for Greater London, so riverside and fire-safety rules involve separate bodies.
London and the Thames: infrastructure
The Thames is tidal and London is vulnerable to flooding, a risk that has grown with rising high-water levels, which affects riverside and low-lying industrial sites.
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 London and the Thames. Near London, 'explosion-proof' at a fuel terminal usually means equipment suitable around tank vents, jetty hose connections and road tanker loading, and sometimes gas network sites. Flameproof Ex d suits fixed items, while intrinsic safety suits a portable device. Terminal operators set the concept area by area under DSEAR.

Specifying an explosion proof smartphone for London
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 · London
Frequently asked questions
Can we buy an explosion proof smartphone in London 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 explosion proof smartphone in London 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 areas at London and the Thames would use it?
Likely candidates are fuel storage terminals, marine jetties, road tanker loading, gas network sites. 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.
Does London's weather matter for handheld devices?
A temperate oceanic climate means mild temperatures but frequent light rain, on about 110 days a year. Typically devices used outdoors need good water ingress protection and users check ratings against site conditions, especially on the tidal Thames.
How should I plan equipment deliveries to London?
Deliveries typically arrive by road or air, and the congested metropolitan area calls for scheduled slots and extra time. Confirm customs treatment for imported electronics and any site access or gate checks with the client.
Why does travel matter for terminal work near London?
The terminals are in Essex, so crews and equipment normally travel by road from the capital, and site access follows each operator's induction and permit rules. Plan time for sign-in, safe-area handover and device checks. Confirm the current access arrangements with the terminal operator.
