Spain: background
REPESA was incorporated in 1948 to build a refinery in the Escombreras valley at Cartagena, so Cartagena is among Spain's oldest refining and chemical locations.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Spain: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Field notes · Spain
More about Spain that matters for portable equipment
Spain: industry on the ground
In 2020 Spain's primary energy came from petroleum (42.3%), natural gas (19.8%), coal (11.6%), nuclear (12%) and renewables (14.3%), so refining, gas and power sites all matter.
Spain: projects and investment
Renewables supplied 46.7% of power consumption in 2021 and Spain was the first country to rely on wind as its top energy source for a full year, so wind and solar construction is a large workload.
Spain: infrastructure
The Port of Tarragona has doubled its bulk-liquid storage area to 36 hectares, holds over 900,000 cubic metres of storage and serves chemical plants through a common pipeline rack, the Dixquimics Rack, with 71 lines.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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 Spain. Intrinsic safety suits the long walking routes within the complexes at Tarragona, Huelva and Cartagena and the rounds at regasification terminals. A handheld that limits ignition energy lets operators photograph, record and communicate in the area. The complexes are widely separated, so one configured handset per crew is practical.

Specifying an intrinsically safe cell phone for Spain
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 · Spain
Frequently asked questions
Can we buy an intrinsically safe cell phone in Spain 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 an intrinsically safe cell phone in Spain cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
Which sites in Spain does this cover?
The market guide for Spain covers Tarragona, Cartagena and Escombreras, Huelva, Campo de Gibraltar, 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.
Where are Spain's main refining and chemical sites?
Cartagena's Escombreras valley is among the oldest refinery locations, and Repsol and other operators run refining and chemical sites on the coasts. Details change, so confirm the current site list and each operator's contractor requirements before planning work.
How do LNG and pipeline gas sites affect device choice in Spain?
Gas entry points, regasification plants and compressor stations are likely Zone 1 or Zone 2 areas, so check the device's gas group and temperature class against the site's classification drawings. Operators typically also require device registration and induction, so allow time before a shutdown.
Will the IS-04Z1 handle Spanish summer heat at a coastal refinery?
It is designed with IP68 sealing and a rugged build for heat, salt and wash-down. The T4 target is judged against the ambient range on the certificate, which is in progress. Check that range against peak August temperatures at your plant before specifying.
