Ex-Proof Mobile Phone in Brazil Oil Platforms
Petrobras was created in 1953 with a legal monopoly, and a 1997 law ended that monopoly and set up the national petroleum agency ANP as the regulator and supervisor of the industry. Pre-salt fields supplied 82 per cent of Petrobras production in 2025, so gas-hazard zones exist on process decks and in storage and offloading areas. If you are specifying an Ex-proof mobile phone for Brazilian offshore oil platforms, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

What Brazilian offshore oil platforms means for portable equipment
FPSO-based fleet
New pre-salt units such as FPSO Almirante Tamandare (Buzios) and FPSO Alexandre de Gusmao (Mero) started up in 2025; FPSOs carry a full process plant on deck.

Brazilian offshore oil platforms: people and language
The P-56 project created about 4,000 direct and 12,000 indirect jobs in Brazil, showing the scale of the domestic shipyard and fabrication workforce that supports offshore units.
Brazilian offshore oil platforms: infrastructure
The semisubmersible P-56 is anchored in 1,670 m of water at the Marlim Sul field, 120 km off the coast, tied back to 21 wells and rated at 100,000 barrels per day with 6 million cubic metres a day of gas compression.
Brazilian offshore oil platforms: projects and investment
The P-50 platform began production in April 2006 in the Albacora-Leste field of the Campos Basin, a milestone that made Brazil self-sufficient in oil production.
Brazilian offshore oil platforms: who works there
Petrobras describes itself as producing about 2.99 million barrels of oil equivalent a day in 2025, and Brazil accounted for roughly 92 percent of its worldwide production in 2014.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Brazilian offshore oil platforms. Process modules, wellhead areas, gas compression and cargo offloading are Zone 1 environments by their nature on production units. A label check should confirm zone suitability, gas group and temperature class against the unit's classification. The IS-04Z1 marking target II 2 G Ex ib IIC T4 remains a target.

Specifying an Ex-proof mobile phone for Brazil Oil Platforms
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 Oil Platforms
Frequently asked questions
Can we buy an Ex-proof mobile phone in Brazil Oil Platforms 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 Ex-proof mobile phone in Brazil Oil Platforms 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 Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Brazilian offshore oil platforms would use it?
Likely candidates are oil and gas process modules, wellhead areas, gas compression, cargo tanks and offloading areas. 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.
Do local-content rules affect equipment used on Brazilian platforms?
Local content has been a factor in Petrobras projects; the P-56 topside, for example, reached 72.9 percent domestic content. Handheld equipment is a small part of that, but confirm with the contractor whether any local-content or Brazilian certification requirement applies to your supply.
What approvals does Brazil typically need for Ex-rated radios and phones?
Typically two layers: conformity assessment for Ex certification (commonly through Inmetro-recognised bodies) and Anatel homologation for radio equipment. Requirements change, so confirm current rules with the operator and a local certification adviser before shipping to a platform.
How do handsets reach an FPSO or platform?
Equipment and crews move by supply vessel and helicopter, so spares and replacements need planning. Operators control access and often check or prepare devices onshore first. Confirm approvals, documentation and delivery routes with the operator and its contractors.
