Finland: infrastructure
About 2.8 million Finns rely on district heating, so combined heat and power plants and fuel handling sites exist in nearly every town.

Intrinsically Safe Cell Phone in Finland
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for the refinery and polymer plants at Kilpilahti, the metal and chemical parks on the Bothnian coast and the mill and mine sites where a winter round is measured in kilometres. If you are specifying an intrinsically safe cell phone for Finland, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Field notes · Finland
More about Finland that matters for portable equipment
Finland: industry on the ground
Bioenergy and waste make up 33.6% of total energy supply and peat 2.7%, with Finland one of the last countries still burning peat, which brings fuel-dust handling into power and heat plants.
Finland: climate and equipment wear
Energy use per capita is the highest in the EU, partly because of energy-intensive industry, a cold climate and long distances, so winter operation of handheld equipment is a normal planning point.
Finland: rules and approvals
The Finnish Safety and Chemicals Agency, Tukes, monitors safety in technology, chemicals and hazardous materials, with divisions for facilities and mines and for products and equipment, and is Finland's competent authority for REACH, CLP and Seveso III.
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 Finland. Winter rounds at Finnish mills, mines and the Bothnian coast parks are measured in kilometres, so operators carry a single device through many areas. An intrinsically safe handheld means a photo, a reading or an inspection note need not wait until the worker is back in a safe zone. That is the design intent, pending certification.

Specifying an intrinsically safe cell phone for Finland
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- 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
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Finland
Frequently asked questions
Can we buy an intrinsically safe cell phone in Finland 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 intrinsically safe cell phone in Finland cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 sites in Finland does this cover?
The market guide for Finland covers Kilpilahti, Porvoo, Naantali, Kokkola, Harjavalta, among others. Site-level pages are linked below.
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.
Do Finnish biomass and peat plants have different explosion risks from refineries?
Yes, because fuel dust from wood, biomass and peat is combustible, so dust zones such as Zone 21 and Zone 22 matter alongside gas zones. Choose devices with dust group marking suitable for the site's classification drawings and the operator's own requirements.
How does Finland's cold climate affect Ex handheld devices?
Winter temperatures can fall well below the minimum rating of ordinary electronics, and battery capacity drops in the cold. Check the lowest rated ambient temperature on the certificate, glove-friendly touch operation and whether charging must happen indoors outside the classified area.
Do contractors at Kilpilahti need their own approved devices?
Gate procedures and contractor rules are set by the operator and the site authority, so requirements vary. A contractor would normally be asked for evidence that a device suits the zones it enters. Check the rules with the site before bringing any device in.
