Hydrogen needs IIC
Equipment marked only for IIB dates quickly in hydrogen work. The IS-04Z1 marking target of II 2 G Ex ib IIC T4 is aimed at IIC for that reason.

Explosion proof mobile phone for Gas, Hydrogen and CO2 in the Netherlands
The Dutch gas sector has shifted from extraction to import, storage, hydrogen and carbon capture. This page is for HSE officers, commissioning engineers and contractors who need an explosion proof mobile phone for gas, hydrogen and CO2 infrastructure in the Netherlands, from LNG terminals to hydrogen pipelines and compression for carbon storage. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.

Where gas, hydrogen and CO2 work is classified
Groningen production ceased in October 2023 and the field closed for good in 2024, so the hazard now sits in import, storage, hydrogen and CO2. Gasunie runs the transmission grid and is building the national hydrogen network, as described on our explosion proof phone for Gasunie page. The Maasvlakte holds LNG import, including the Gate terminal, and the site of Shell’s Holland Hydrogen 1 electrolyser project, and Eemshaven has an LNG terminal and power generation. Carbon capture projects such as Porthos will add compression and pipelines. Natural gas is group IIA, hydrogen is IIC, and CO2 is not flammable but is handled with flammable products.
Sites and operators
- Gasunie and HyNetwork Services

New classified areas are being created faster than the standards for them are settled. These conditions follow from that.

Small commissioning teams
New plant is commissioned by small teams. One handset that carries documents, camera and position replaces several tools.
Remote and dispersed assets
Pipelines and stations are spread out. Four-constellation GNSS and a 50 MP camera attach a position and photograph to each inspection.
Managed from the start
Android Enterprise lets the owner apply policy to new devices from day one, as new sites join the network.

How the work is organised on gas and hydrogen sites
Commissioning01
New hydrogen and CO2 plant
A commissioning team checks lines, valves and instruments in areas that are newly classified, often before the full operating routine exists. Loop checks, purge records and punch-list photographs all need a home, and a handset carrying drawings, photographs and a position record keeps them with the asset rather than in a contractor’s notebook.
Terminals02
LNG import
Terminal staff walk between ship connections, vaporisers and storage, often in cold, windy conditions at the waterside. The handset covers voice, camera and a lone-worker check-in on one device, so that a ship transfer can be reported from where it happens.
Network03
Pipeline and station inspection
Inspectors visit stations and valve sites on a schedule, many of them small and unmanned, recording results with photographs and positions. The record is only as good as the position it carries, so four-constellation GNSS is a working requirement, not an extra.

What operators would ask a supplier for
Each operator sets its own supplier requirements, and we have not verified specifics for any. The route is to ask the operator’s procurement and HSE teams. Below is what operators in this sector typically want.
Documents to prepare
- Marking and gas group
- The ATEX marking string, gas group IIC and temperature class once issued.
- Dutch documentation
- Manual, safe-use instructions and declaration of conformity in Dutch.
- Management guide
- Enrolment steps for the MDM, with camera policy.
- Service route
- How an intrinsically safe handset is serviced.
Questions · Gas, Hydrogen and CO2
Frequently asked questions
Is CO2 a hazard for a phone?
CO2 is not flammable, so it does not create a classified area by itself. Carbon capture sites do handle flammable products nearby, such as fuel gas and process streams, and it is those that set the zones. Compression plant and pipelines for CO2 also add pressure and cold hazards that sit outside the Ex marking.
Why not equipment marked IIB?
Hydrogen is group IIC, with a very low ignition energy. Equipment marked only for IIB is not appropriate where hydrogen is present, and a site converting from natural gas to hydrogen may find that handsets bought for the old duty no longer fit the new area classification.
Does the handset work on new sites?
It runs Android 16 under Android Enterprise, so it can be enrolled wherever a console exists.

Ask about the IS-04Z1 for Gas, Hydrogen and CO2, Netherlands
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Netherlands. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
