Explosion-Proof Smartphone in Rio de Janeiro
Rio de Janeiro is the headquarters city of Petrobras and a base for Brazil's offshore oil industry. 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. If you are specifying an explosion proof smartphone for Rio de Janeiro, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Rio de Janeiro that matters for portable equipment
Rio de Janeiro: who works there
Petrobras has its headquarters in downtown Rio de Janeiro, which is why many supplier registrations, tender offices and engineering teams for the whole Brazilian oil sector are in the city.
Rio de Janeiro: projects and investment
Petrobras' refining plan includes the Boaventura Energy Complex in Rio de Janeiro state and a revamp of the Duque de Caxias refinery, so project activity remains close to the city.
Rio de Janeiro: background
Petrobras was created in 1953; its Reduc refinery started up near Rio in 1961 and its Cenpes research centre was founded in 1963, giving the city a long record in refining and technology.
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.
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 Rio de Janeiro. Rio itself is not a plant, so explosion-proof applies at the refineries, shipyards, tank terminals and offshore support bases in neighbouring municipalities. Fixed gear may be flameproof Ex d, and a portable handset relies on intrinsic safety. The IS-04Z1 is designed for the latter, pending certification.

Specifying an explosion proof smartphone for Rio de Janeiro
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 · Rio de Janeiro
Frequently asked questions
Can we buy an explosion proof smartphone in Rio de Janeiro today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an explosion 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.
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 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.
