More about Rio de Janeiro that matters for portable equipment
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: 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: 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.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Rio de Janeiro. The hazardous areas associated with Rio lie in neighbouring municipalities: refinery process units at Duque de Caxias, shipyards and FPSO yards, tank terminals and offshore support bases. Operators classify these areas. The city itself is not a plant, and SAMS does not classify any area.

Questions · Rio de Janeiro
Frequently asked questions
Can we buy a hazardous area 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 a hazardous area smartphone 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
