Intrinsically Safe Mobile Phone in Rio de Janeiro
Rio de Janeiro is the headquarters city of Petrobras and a base for Brazil's offshore oil industry. 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. This page explains what to look for in an intrinsically safe mobile phone for Rio de Janeiro, and where the IS-04Z1 stands against that list today.

Field notes · Rio de Janeiro
More about Rio de Janeiro that matters for portable equipment
Rio de Janeiro: logistics and access
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.
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.
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.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Rio de Janeiro. Staff based in Rio who travel to Duque de Caxias, Angra dos Reis, Itaborai or Niteroi for audits need one device that can enter classified areas on arrival. An intrinsically safe handheld fits that mobile role. The IS-04Z1 is designed for it, subject to certification.

Specifying an intrinsically safe mobile phone 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 intrinsically safe mobile phone 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 intrinsically safe mobile phone in Rio de Janeiro 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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
