Intrinsically Safe Smartphone in Angra dos Reis
Angra dos Reis is a municipality in the south of Rio de Janeiro state on Ilha Grande bay. It hosts the Transpetro TEBIG crude oil terminal and the BrasFELS shipyard, so tank-farm, tanker-berth and offshore-unit fabrication hazardous areas are both present. If you are specifying an intrinsically safe smartphone for Angra dos Reis, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

A metre-gauge railway extension from the 1920s still links the port with Minas Gerais and Goias, and the steel company CSN uses the port for some exports.
Angra dos Reis: projects and investment
After final outfitting the P-56 went through testing and adjustment in Ilha Grande Bay before being towed to the Campos Basin, a typical pattern for offshore units completed at Angra dos Reis.

Brazil's Angra I and Angra II nuclear units are located near the town and employ about 3,000 people, with a further 10,000 indirect jobs in Rio de Janeiro state.
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 Angra dos Reis. Pier walks, tank inspections and bunker barge checks suit a compact device that is safe to carry near vapour. At the yard, inspectors moving between hull, topside modules and quay can photograph defects without swapping devices. The IS-04Z1 is designed to be intrinsically safe for such rounds, once certification completes.

Specifying an intrinsically safe smartphone for Angra dos Reis
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 · Angra dos Reis
Frequently asked questions
Can we buy an intrinsically safe smartphone in Angra dos Reis 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 smartphone in Angra dos Reis cost?
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.
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 Angra dos Reis would use it?
Likely candidates are crude oil tank storage, tanker piers and loading arms, shipyard offshore-unit fabrication and integration, bunker fuel barge supply. 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.
Does the coastal humidity at Angra dos Reis affect phone and tablet choice?
Yes, typically. A tropical monsoon climate and sea air mean high humidity and salt, so look for sealed housings, corrosion-resistant connectors and tidy cable or charging practice. Confirm with the site safety officer what ingress protection level their permit-to-work process expects.
How do crews reach island or offshore worksites from Angra dos Reis?
Access is generally by boat across the Bay of Ilha Grande, with many of the 300-plus islands reachable only by sea, and some units are later towed to the Campos Basin. Confirm boarding and carry-on rules for powered devices with the vessel operator.
How does the tropical climate affect handsets on piers and in the yard?
Rain, humidity and salt air are routine, so check enclosure rating, seal condition and charging contacts regularly. IP68 resists water and dust but is not explosion protection. Because ingress protection and travel time both matter on this coast, keep a spare device ready.
