Portugal: who works there
Galp Energia, formed in 1999 from Petrogal, Gás de Portugal and Transgás, is Portugal's largest oil and gas group, with business units covering upstream, refining and midstream, commercial, and renewables.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, aimed at the refining and polymer complex at Sines, the chemical plants at Estarreja and the pulp, cement and mining sites in between. This page sets out how an intrinsically safe smartphone supply route to Portugal 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 Portugal 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Portugal. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS Portugal market guide.
Galp Energia, formed in 1999 from Petrogal, Gás de Portugal and Transgás, is Portugal's largest oil and gas group, with business units covering upstream, refining and midstream, commercial, and renewables.
The Sines hard coal power plant operated from 1985-1989 until January 2021 and coal-fired generation ended in 2021, so former coal sites are being redeveloped.
Oil made up 44% of Portugal's total energy supply in 2023, so fuel storage, port terminals and distribution depots form a large part of the classified-area infrastructure.
In 2021 Portugal imported 2.8 billion cubic metres of LNG from Nigeria, almost 50% of its gas imports that year, so ship-to-shore LNG operations are central to gas supply.
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 Portugal. Large sites and small crews mean a single operator may cover long rounds across Sines, Estarreja or a pulp mill at Figueira da Foz. An intrinsically safe handheld lets one person log findings, photograph equipment and run a work-order app without returning to a control room for each entry.
There is no stock to order for Portugal yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.
The technical specification, marking target and conditions of use, sent by email.
Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated 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 Portugal covers Sines, ZILS Alentejo, Estarreja, Matosinhos and Leça, 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.
Atlantic coastal sites are salt-laden and summers can be hot, so check the maximum ambient temperature on the certificate, the water and dust ingress rating and the condition of charging contacts. Sealed connectors and regular cleaning are typically recommended for coastal terminals.
Portugal has a hydrogen strategy aimed at reducing gas imports by 2030, so hydrogen projects may create new classified areas. Hydrogen belongs to a more demanding gas group than propane, so check the gas group marking of a device against the project's area classification.
Sites such as Sines or the Alentejo interior can be far from anyone who services equipment, so a reachable service route matters. SAMS has appointed no distributor yet. Before purchase, ask what repair, replacement and battery support would be available for your plant, and agree it in writing.
