Reduc lies about 17 km from downtown, and Guanabara Bay hosts shipyards such as Brasa at Niteroi.
Rio de Janeiro is the headquarters city of Petrobras and a base for Brazil's offshore oil industry. 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. If you are specifying a hazardous area mobile phone for Rio de Janeiro, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Rio de Janeiro: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |
| Area drawing | The operator's own classification drawing | Decided by the site operator |
| Where it applies | Rio de Janeiro: Refinery process units (Duque de Caxias), Shipyards and FPSO yards, Tank terminals | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Rio de Janeiro. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Reduc lies about 17 km from downtown, and Guanabara Bay hosts shipyards such as Brasa at Niteroi.
Heat, humidity and coastal salt are normal.
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 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.
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.
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.
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.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.
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.
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.
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.
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.
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.
