Ex-Proof Smartphone Distributor 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. Gas network and utility sites add smaller classified areas. Distribution partners for London and the Thames are being identified ahead of the Q4 2026 launch of the IS-04Z1.

Short answer. London and the Thames 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.
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.

Field notes · London and the Thames
More about London and the Thames that matters for portable equipment
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.
London and the Thames: logistics and access
The Port of London covers the tidal Thames from Teddington Lock to a boundary line out in the North Sea, is governed by the Port of London Authority (a public trust since 1908), and was the UK's largest port in 2020.
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 London and the Thames. A marking check at the Thames terminals would compare each loading rack, jetty and tank farm zone with the label on the device. Petroleum products and chemicals at West Thurrock may involve differing gas groups, so IIC marking offers margin. The IS-04Z1 target is II 2 G Ex ib IIC T4, pending certification; operators confirm suitability.
The route · distribution
Distributing the IS-04Z1 in London
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for London and the Thames. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device 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 London and the Thames.
- 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 · London
Frequently asked questions
Can we buy an Ex-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 Ex-proof smartphone in London 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.
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 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.
How do I become a SAMS distributor for London and the Thames?
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 London and the Thames.
Who should I contact about explosive atmospheres in London workplaces?
Employers are responsible under the Dangerous Substances and Explosive Atmospheres Regulations, enforced by the Health and Safety Executive or local authorities, and the London Fire Brigade handles fire safety. Ask the premises for its hazardous-area register and risk assessment.
Is London a hazardous-area site or mainly a place for meetings and approvals?
Mainly the latter. Head offices, regulators, consultants and insurers are concentrated in London, while major process plants and terminals are in estuary and regional locations elsewhere. Confirm the actual site and its classification before assuming any hazardous-area requirement.
Does London have refineries or only terminals?
No refinery. The former Coryton refinery stopped refining in 2012 and became the Thames Oilport fuel import terminal, and a large terminal operates at West Thurrock in Essex. Both are on the Thames estuary outside Greater London. Confirm access and equipment requirements with the site operator.
