More about Borlänge that matters for portable equipment
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.
Borlänge: geography and layout
The town lies on the Dalälven river downstream of the confluence of the Österdalälven and Västerdalälven, and it is the largest urban centre in the province of Dalarna, with about 44,900 residents in 2020.
Borlänge: industry on the ground
SSAB describes its Borlänge works, established in 1878, as its largest strip rolling system, making hot-rolled and cold-rolled high-strength steel for automotive, heavy-duty transport, lifting and container uses, with around 1,700 employees.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Borlänge. In everyday talk at a steelworks or paper mill, explosion-proof often covers every protection concept. Here the real choice is between flameproof enclosures, Ex d, on fixed plant and intrinsic safety on portable devices. Fuel and process gas systems and dust areas each need their own assessment, so ask which concept the operator expects.

- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status

Questions · Borlänge
Frequently asked questions
Can we buy an explosion proof mobile phone in Borlänge 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 an explosion proof 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still 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.
