Refineries sit in the south-east, south, north-east and elsewhere, so logistics differ by site.

Intrinsically Safe Smartphone in Brazil Refineries
This is a regional grouping rather than a single site. Petrobras operates about ten refineries in Brazil, including Replan at Paulinia (415,000 barrels a day), Revap at Sao Jose dos Campos and Reduc at Duque de Caxias, each with classified process, storage and loading areas. If you are specifying an intrinsically safe smartphone for Brazilian refineries, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

WhereBrazil Refineries
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Brazilian refineries: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

Brazilian refineries: projects and investment
At the Gabriel Passos refinery (Regap) in Betim, Minas Gerais, capacity of 166,000 b/d is being raised by 25,000 b/d with start-up planned for 2027, and sustainable aviation fuel production is being introduced.
Brazilian refineries: who works there
The Abreu e Lima refinery in Ipojuca, Pernambuco, is being expanded with a new production line to refine heavy crude from the pre-salt region.
Brazilian refineries: who works there
Of eight refineries once offered for sale, only two were sold (Mataripe and the Manaus refinery), and Petrobras later resumed investing in the rest of its refining park.
Brazilian refineries: logistics and access
The same plan allocates 2.1 billion dollars to remove logistics bottlenecks, including expanding and optimising terminals and transport infrastructure that serve the refineries.
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 Brazilian refineries. Planned maintenance shutdowns bring large contractor workforces into process units, and Reduc has shutdowns scheduled in 2026. A handheld that is intrinsically safe suits walkdowns, punch lists and inspections in those units. The IS-04Z1 is designed for this use, pending certification.

Specifying an intrinsically safe smartphone for Brazil Refineries
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 · Brazil Refineries
Frequently asked questions
Can we buy an intrinsically safe smartphone in Brazil Refineries 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 smartphone in Brazil Refineries 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.
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 areas at Brazilian refineries would use it?
Likely candidates are refinery process units, crude and product tank farms, loading racks and jetties, hydrotreater and hydrogen units. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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 are devices usually approved for Petrobras refineries?
Refinery contractors typically check Ex certification marking, temperature class and gas group against the area classification, plus local radio approval. The detail varies by site and contractor, so confirm the requirement with the refinery safety group and your contractor induction pack.
Do refinery turnarounds change the device requirements?
Often. During shutdowns and revamps, work shifts between live and isolated units, and permits define which areas are gas-tested. Many sites keep the same Ex requirement for the whole fence line to avoid errors, so confirm with the operator and the turnaround contractor.
When is the best time to deploy handsets at a refinery?
Maintenance shutdowns are a natural point, because large contractor workforces enter classified areas, and Reduc has shutdowns scheduled in 2026. Plan MDM enrolment and charging well before mobilisation. Confirm timing and rules with the site operator, as schedules change.
