Climate
Humid continental climate with cold winters (January averages about -1 degrees C), so outdoor rounds in winter call for cold-tolerant batteries and gloved operation.

Intrinsically Safe Mobile Phone in Borlänge
Borlänge is the largest urban centre in Dalarna, central Sweden, and is built around the SSAB Domnarvet strip-steel works and the Stora Enso Kvarnsveden paper mill. Steel and paper processing involve fuel gas, chemicals and fine dust, so Zone 1 and Zone 21 classification can apply in plant areas. This page explains what to look for in an intrinsically safe mobile phone for Borlänge, and where the IS-04Z1 stands against that list today.

More about Borlänge that matters for portable equipment
Borlänge: logistics and access
Borlänge Central is a railway junction for routes toward Falun, Mora and Ludvika and links to Gävle and Stockholm, and Dala Airport lies 8 km south-east, with Arlanda 214 km away.
Borlänge: people and language
Dalarna University was founded in 1977 as a joint college for Falun and Borlänge, and the town hosts the head office of the Swedish Transport Administration, Trafikverket.
Borlänge: industry on the ground
Borlänge has long been an industrial town around the Domnarvet iron and steel works, now SSAB, and the Kvarnsveden paper mill, owned by Stora Enso.
Borlänge: background
Construction of the Domnarvet ironworks began in 1872, and a railway between Falun and Ludvika via Borlänge opened in 1875, making the town a strategic junction for the works.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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 Borlänge. Winter rounds at a large works mean gloved hands and long walks between units. A handheld intrinsically safe device lets an operator photograph a fault or log a reading in a classified area without carrying a separate terminal. The IS-04Z1 is designed with a 50 MP camera and Android 16 for that kind of use.

Questions · Borlänge
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Borlänge today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an intrinsically safe mobile phone in Borlänge 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 does ‘intrinsically safe’ mean for the IS-04Z1?
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.
Which areas at Borlänge would use it?
Likely candidates are fuel and process gas systems, chemical and oil storage, dust-generating process areas (zone 21). 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.
Is Swedish winter weather a problem for devices at Borlänge?
Inland Dalarna can be cold in winter, so batteries and touchscreens may perform less well outdoors. Typically users keep spare batteries warm and check the device's rated temperature range against site conditions, while mills and steelworks may require protective cases.
Does a paper mill like Kvarnsveden have explosive atmospheres?
Mills typically have combustible dust from wood and fibre, flammable gases in energy and chemical recovery areas, and solvent stores. Each site classifies its own areas, so ask the mill's safety team for zone drawings and whether handheld devices are permitted.
How do contractors get a phone into the SSAB or Stora Enso works at Borlänge?
Large works here run their own contractor induction and permit-to-work systems, so access to classified areas is arranged through each operator. A phone would normally be listed and approved as part of that process. Ask the operator's HSE or procurement team what device evidence it requires.
