Explosion-Proof Mobile Phone in Campos Basin
The Campos Basin is an offshore oil province off Rio de Janeiro and Espirito Santo states, covering about 115,000 square kilometres. By 2003 some 41 oil and gas fields had been discovered 50 to 140 km from the coast in water 80 to 2,400 m deep, and the basin was producing about 1.21 million barrels per day. If you are specifying an explosion proof mobile phone for Campos Basin, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Offshore climate
Salt, humidity and heat are normal, so equipment is commonly checked onshore before it goes offshore.

More about Campos Basin that matters for portable equipment
Campos Basin: geography and layout
The Campos Basin covers about 115,000 km2, almost all of it offshore, with only about 500 km2 onshore near Rio de Janeiro, and is one of 12 coastal sedimentary basins in Brazil.
Campos Basin: projects and investment
A 65 million barrel discovery was announced by Petrobras near the Barracuda field in February 2010, showing continued exploration activity in this mature basin.
Campos Basin: infrastructure
Production comes from varied reservoir types, including turbidite sandstones, fractured basalts, coquinas and limestones, which leads to a mix of facility designs and well services across the basin.
Campos Basin: rules and approvals
Roncador ranked first among the top fields of the Santos, Campos and Espirito Santo basins in 2010 at 129.7 million barrels of oil equivalent, and the Campos Basin had eight discoveries in 2011.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Campos Basin. Offshore in the Campos Basin, the phrase explosion-proof covers platform process modules, wellhead areas, crude storage and offloading, and gas compression. Fixed gear may be Ex d; a handheld relies on intrinsic safety. The IS-04Z1 is designed for the latter, and certification remains pending.

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

Questions · Campos Basin
Frequently asked questions
Can we buy an explosion proof mobile phone in Campos Basin 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 explosion proof mobile phone in Campos Basin 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which areas at Campos Basin would use it?
Likely candidates are platform process modules, wellhead areas, crude storage and offloading, gas compression. 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 older and newer platforms in the Campos Basin differ for device approval?
Not necessarily, but the operator differs. Some shallow fields passed to Trident Energy in 2020 while Petrobras runs many others, so induction rules and approved-device lists can vary. Confirm with each operator's safety team which markings and approvals they accept.
What hazardous areas appear on Campos Basin production units?
Typically wellheads, separation and gas treatment, compression, crude storage and offloading, and the helideck fuel area. Classification drawings from the unit operator give the exact zones, gas groups and temperature classes, so request them before choosing a handheld device.
Are older platforms a particular concern for device selection?
The basin is mature, and many older units need regular maintenance, so rounds are frequent. That favours a rugged, intrinsically safe handheld, but each platform has its own classification. Ask the operator for it rather than assuming that one marking suits every unit.
