Finland: who works there
Neste was founded in 1948 as the state petrol company and was the third largest Finnish company by revenue in 2021, with the Finnish state holding 35.91% of shares in 2022.
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 explosion proof mobile phone for Finland, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned 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.
Neste was founded in 1948 as the state petrol company and was the third largest Finnish company by revenue in 2021, with the Finnish state holding 35.91% of shares in 2022.
Neste built Finland's first refinery at Naantali in 1957 and the Porvoo refinery at Sköldvik (Kilpilahti) in 1965, so Naantali and Porvoo are the traditional centres of refining.
Finland lacks domestic fossil energy and imports substantial petroleum and natural gas, so refining, fuel terminals and gas-supply sites are mostly import-led rather than field-based.
The industrial sector accounted for 53% of total final energy consumption in 2021, well above the IEA average, so process industry sites strongly shape the demand for classified-area equipment.
“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 Finland. Explosion-proof is the everyday phrase, but in a Finnish chemical park the real choice is between protection concepts. Flameproof Ex d encloses an ignition, while intrinsic safety limits the energy so none can occur. For a handheld carried through a cracker, a recovery boiler area or a conveyor gallery, the IS-04Z1 is designed around intrinsic safety.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.
The market guide for Finland covers Kilpilahti, Porvoo, Naantali, Kokkola, Harjavalta, among others. Site-level pages are linked below.
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.
Finland is an EU member, so ATEX Directive 2014/34/EU applies to equipment placed on the market and employers zone workplaces under Directive 1999/92/EC. Operators usually also apply their own permit and device registration processes. Ask the site safety office for its current list.
Neste built refineries at Naantali in 1957 and at Porvoo, in the Kilpilahti area, in 1965. Fuel terminals and gas-supply sites serve the rest of the country. Individual site rules and current operations should be confirmed with the operator before a visit.
The IS-04Z1 is designed for industrial duty with IP68 sealing, but cold performance of any lithium battery needs testing. Ask for the datasheet's operating temperature range and trial a unit on an actual winter round. Site rules on charging and storage in safe areas still apply.
