Ex-Proof Smartphone in Macaé
Macae Airport now has six helicopter operators meeting the safety standards Petrobras requires, with seven hangars, four shared lounges and a workspace area in the check-in hall. It is the operational base for the Campos Basin, with Petrobras facilities, offshore service companies, the Imbetiba port and an airport used for flights to offshore platforms. This page explains what to look for in an Ex-proof smartphone for Macae, and where the IS-04Z1 stands against that list today.

More about Macae that matters for portable equipment
Macae: industry on the ground
Macae is generally considered the centre of Brazil's offshore petroleum industry and is nicknamed Cidade do Petroleo (City of Petroleum), with many Petrobras facilities inside the town.
Macae: background
Since the 1970s, when Petrobras chose Macae as its Campos Basin base, more than 4,000 companies have set up offices there and the population has roughly tripled.
Macae: logistics and access
An airport spotting guide reports about 2,000 helicopter operations a month, around 60 to 70 a day, mostly medium and heavy helicopters, plus two daily scheduled airline flights.
Macae: infrastructure
A new 1,410 metre runway, a roughly R$220 million investment by the airport concessionaire Zurich Airport Brasil, is being built to let larger aircraft use the airport.
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 Macae. A marking check in Macae is often a pre-shipment test: is the device suited to the zone, gas group and temperature class that it will meet offshore? Workshops and fuel storage have their own classification too. The IS-04Z1 target marking II 2 G Ex ib IIC T4 is not yet certified.

Specifying an Ex-proof smartphone for Macaé
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking

- 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 · Macaé
Frequently asked questions
Can we buy an Ex-proof smartphone in Macaé 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 an Ex-proof smartphone in Macaé 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 Macae would use it?
Likely candidates are offshore supply bases and quays, heliport and fuel storage, workshops handling offshore equipment, onshore oil and gas handling. 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.
Are there limits on devices carried on offshore helicopter flights from Macae?
Helicopter operators and platform owners set rules for batteries, radios and phones, and they differ. Typically devices are checked at the heliport and may need to be stowed or switched off. Confirm with the operator and heliport safety desk before travel.
Why is Macae the usual base for offshore equipment and personnel?
Petrobras placed its Campos Basin base there and the airport concentrates helicopter transfers to platforms. More than 4,000 companies are registered, so servicing, storage and training are nearby. Confirm freight, customs and storage arrangements with a local logistics company.
Is Macae itself a hazardous area?
Parts of it are, such as supply bases and quays, heliport fuel storage, workshops handling offshore equipment and onshore oil and gas handling, but it is a support city rather than a production site. Confirm the classification of each facility with its operator.
