Ex-Proof Smartphone in Rio de Janeiro
The Port of Rio de Janeiro is the third-busiest in Brazil, with a 6.7 km pier, 31 berths and drafts of 10 to 15 metres, and it handles petrochemicals among its cargoes, with road and rail access. Hazardous-area work in the surrounding state is at refineries, terminals and shipyards in neighbouring municipalities such as Duque de Caxias, Angra dos Reis, Itaborai and Niteroi. If you are specifying an Ex-proof smartphone for Rio de Janeiro, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Rio de Janeiro: geography and layout
The 2007 and 2008 Santos Basin pre-salt discoveries (Tupi, Jupiter and Sugar Loaf) lie about 300 km off the coast of Rio de Janeiro, tying the city to deepwater supply and service work.
Rio de Janeiro: logistics and access
Galeao International Airport lies on Governador Island in Guanabara Bay, while Santos Dumont Airport is the city's second airport, so equipment and visitors can arrive at two separate airfields.
Rio de Janeiro: background
Rio was founded in 1565, became seat of the Portuguese court in 1808 and stands on Guanabara Bay, with the Rio-Niteroi Bridge a landmark route to the Niteroi side of the bay.
Rio de Janeiro: industry on the ground
Rio has the second-largest municipal GDP in Brazil and is home to the headquarters of major oil, mining and telecommunications companies, including Petrobras and Vale, concentrating decision-makers in one city.
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 Rio de Janeiro. A marking check begins by asking which site the handset will enter: Reduc, a Guanabara Bay shipyard, a tank terminal or an offshore base. Each classification differs. Compare zone, gas group and temperature class with the label. The IS-04Z1 target marking II 2 G Ex ib IIC T4 is not yet certified.

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

Questions · Rio de Janeiro
Frequently asked questions
Can we buy an Ex-proof smartphone in Rio de Janeiro 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 smartphone in Rio de Janeiro cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 Rio de Janeiro would use it?
Likely candidates are refinery process units (duque de caxias), shipyards and fpso yards, tank terminals, offshore support bases. 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.
Is Rio humidity a concern for stored equipment?
Rio's coastal setting is warm and humid, so spare devices are best kept in dry cases with desiccant and checked for condensation before use. Confirm storage guidance in the warehouse or base procedures.
Does the city of Rio itself contain hazardous areas?
Mostly in the port, fuel terminals and refining sites around Guanabara Bay rather than in the central city. Check the exact location with the project, because zones are set by each facility's classification study.
Which nearby sites might a Rio-based team visit?
Reduc at Duque de Caxias, about 17 km from downtown, Guanabara Bay shipyards such as Brasa at Niteroi, Angra dos Reis and Itaborai. Each has its own classification and rules. Confirm approvals and documentation requirements with the site operator.
