Turnaround cycles
Planned maintenance shutdowns bring large contractor workforces into classified areas; Reduc, for example, has shutdowns scheduled in 2026.

Hazardous Area Mobile Phone in Brazil Refineries
This is a regional grouping rather than a single site. 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. If you are specifying a hazardous area mobile phone 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.

What Brazilian refineries means for portable equipment
Ownership has changed
Petrobras has sold some refineries (for example RLAM in Bahia and Reman in Manaus), so procurement rules differ by owner.

Brazilian refineries: who works there
Petrobras' REPLAN refinery at Paulinia, Sao Paulo, is the largest in Brazil at 434,000 barrels per day, and the 208,000 b/d REPAR refinery at Araucaria, Parana, is another major site in the 2024-28 plan.
Brazilian refineries: infrastructure
Regap has a photovoltaic plant of 13,300 kW with about 20,000 solar panels, the first at a Petrobras refinery, and Petrobras plans 55.5 MW of solar capacity across its refining sites.
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
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.
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 Brazilian refineries. This grouping covers about ten Petrobras refineries, so classified areas include process units, crude and product tank farms, loading racks and jetties, hydrotreater and hydrogen units, and flare and wastewater areas. Each refinery operator classifies its own plant. SAMS does not classify any area.

Specifying a hazardous area mobile phone 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 a hazardous area mobile phone in Brazil Refineries today?
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.
What does a hazardous area mobile phone in Brazil Refineries 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.
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 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.
