Denmark: logistics and access
Port Esbjerg calls itself the world's largest base port for offshore wind activities and says it has been involved in shipping components to more than 65 offshore wind projects.
The IS-04Z1 is an explosion proof mobile phone designed for Zone 1 and Zone 21, from a wet deck 225 km west of Esbjerg to a fermentation building at Kalundborg and a biogas upgrading skid on Lolland. This page sets out how an intrinsically safe cell phone supply route to Denmark will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An intrinsically safe cell phone for Denmark cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Denmark. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS Denmark market guide.
Port Esbjerg calls itself the world's largest base port for offshore wind activities and says it has been involved in shipping components to more than 65 offshore wind projects.
Denmark imports about 12% of its energy but is also an exporter, and its electricity grid is connected by transmission lines to other European countries.
Denmark has North Sea oil and gas but ranked only 57th among net crude exporters in 2023 after ranking 32nd in 2008, so offshore work is mature, with decommissioning and maintenance a larger share.
North Sea natural gas projects began in 1984 and North Sea production made Denmark self-sufficient in energy in 1997, which explains the established offshore supply chain on the west coast.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Denmark. Biogas plants and remote terminals are often worked by one technician with the nearest colleague a drive away, and offshore rounds start from Esbjerg. An intrinsically safe handheld is designed for these rounds, with four-constellation GNSS and 4G LTE holding a position and a link, and a 4,000 mAh battery for the shift.
There is no stock to order for Denmark yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.

Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.

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.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
The market guide for Denmark covers Esbjerg, The Danish North Sea, Fredericia, Kalundborg, among others. Site-level pages are linked below.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Cold, wet and windy conditions affect battery life and touchscreen use with gloves, particularly offshore and at wind farms. Check the lowest rated ambient temperature on the certificate, the water ingress rating and whether touch input works with wet or gloved hands.
Typically the EU declaration of conformity, the certificate, the Ex marking details and instructions in the local language, which may be Danish or English depending on the operator. Request the site's equipment register template so supplier documents can be matched to it.
The classification of areas into zones comes from the emergency management agency under an executive order, while the employer's duty to assess explosion risk and hold an explosion protection document comes from the Danish Working Environment Authority. SAMS classifies nothing. Confirm the arrangement with the site operator for your plant.
