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.

Hazardous Area Mobile 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. This page explains what to look for in a hazardous area mobile phone for Finland, and where the IS-04Z1 stands against that list today.

WhereFinland
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Finland: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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 · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Finland. Finnish classified areas range from the Kilpilahti refinery and cracker to kraft mill recovery boilers, lime kilns and chip piles, plus gas network sites such as the Inkoo terminal. Classification is carried out by the operator, in line with national rules, not by SAMS. The device must then be matched to each zone and dust or gas group.

Specifying a hazardous area mobile 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 a hazardous area mobile phone in Finland today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does a hazardous area mobile phone in Finland 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
