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.
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. This page sets out how an intrinsically safe smartphone supply route to Finland 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 smartphone for Finland 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Finland. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS Finland market guide covers.
About 2.8 million Finns rely on district heating, so combined heat and power plants and fuel handling sites exist in nearly every town.
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.
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.
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.
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.
Supply of the IS-04Z1 to Finland starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.

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 Finland covers Kilpilahti, Porvoo, Naantali, Kokkola, Harjavalta, 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.
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.
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.
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.
