Estuary location
The terminals are on the Thames estuary in Essex, not inside Greater London, so site access involves road transfers from the capital.

Hazardous Area Smartphone Distributor in London
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. Gas network and utility sites add smaller classified areas. A hazardous area smartphone distributor in London and the Thames would carry the IS-04Z1 to these buyers once certification completes.

More about London and the Thames that matters for portable equipment
London and the Thames: background
The Port of London expanded downstream in the 18th and 19th centuries, and the Underground, the world's first urban rail network, was created to ease traffic congestion.
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.
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 London and the Thames. London itself has no refinery. The classified areas are at Thames-side fuel terminals, namely Thames Oilport on the former Coryton site and West Thurrock in Essex, with marine jetties, road tanker loading and gas network sites. The terminals lie on the estuary in Essex, not inside Greater London, and the operators classify the zones.

Questions · London
Frequently asked questions
Can we buy a hazardous area smartphone in London today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does a hazardous area 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.
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 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.
