Warm humid climate
Niteroi has a tropical monsoon climate with warm temperatures year-round and frequent rain.
The Mauá shipyard grew from a Niterói foundry and shipyard bought in 1846 by Baron of Mauá, and its 2000 joint venture with Jurong Shipyard added construction of oil and gas platforms. The Brasa yard there, a partnership of SBM Offshore and Synergy operating since 2012, integrates FPSO topside modules with hulls for pre-salt service, so shipyard hazardous areas are present. A hazardous area mobile phone distributor in Niteroi would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Niteroi has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Niteroi. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Niteroi has a tropical monsoon climate with warm temperatures year-round and frequent rain.
The 65,000 square metre yard is within the Rio metropolitan area across the bay from downtown.
The municipality contains part of the 2,400 hectare Serra da Tiririca State Park, created in 1991, which affects where new industrial or construction projects can be sited.
Niteroi has a tropical monsoon climate with warm to hot temperatures all year and relatively frequent rainfall, so humidity is a constant factor for equipment stored or used outdoors.
The Rio-Niterói Bridge, completed in 1974, is 13.29 km long and has a 72 m high central span so that ships can pass into Guanabara Bay, linking Niterói to Rio de Janeiro by road.
Niteroi lies across Guanabara Bay from Rio de Janeiro; it was founded in 1573 and served as capital of Rio de Janeiro state until 1975, apart from a short period from 1894 to 1903.
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 Niteroi. Niteroi is mainly a commercial city, so the classified areas here are essentially the shipyard: module fabrication and integration, tank and hull work, and fuel and gas handling at quaysides. The yard operator classifies them for each job; SAMS does not.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Niteroi. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
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 fpso module fabrication and integration, shipyard tank and hull work, fuel and gas handling at quaysides. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Niteroi.
Local-content requirements are a decisive factor in Petrobras tenders, and shipyards respond to them. For handheld devices it is usually a contractor-level question, so confirm with the yard or main contractor whether domestic sourcing or registration applies.
A tropical monsoon climate means warm, humid weather and frequent rain, so sealed cases, drying routines and spare batteries are sensible. Confirm the operator's ingress protection and temperature requirements for outdoor classified areas.
Only where the work is classified, such as tank and hull work or fuel and gas handling at quaysides, as set by the yard and its HSE team. Other areas may not be. Confirm the classification for each job with the site operator.
