Field notes · Portugal
More about Portugal that matters for portable equipment
Portugal: background
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.
Portugal: industry on the ground
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.
Portugal: logistics and access
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.
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 Portugal. Portuguese classified areas include the Sines refinery, polymer complex, LNG terminal and port, Estarreja chemicals, former refinery storage at Matosinhos, cement and pulp at Setúbal, Figueira da Foz and Aveiro, and the Neves-Corvo mine. The operator classifies each area, so SAMS does not issue drawings.
The route · specification
Specifying a hazardous area mobile phone for Portugal
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 · Portugal
Frequently asked questions
Can we buy a hazardous area mobile phone in Portugal today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does a hazardous area mobile phone in Portugal 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.
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 Portugal does this cover?
The market guide for Portugal covers Sines, ZILS Alentejo, Estarreja, Matosinhos and Leça, 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.
How does Portuguese coastal weather affect Ex handheld devices?
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.
Will hydrogen change hazardous-area needs in Portugal?
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.
How far is service from a Portuguese site?
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.
