Ports
The city has two seaports, the Jubail Commercial Seaport and the King Fahd Industrial Seaport.
Jubail Industrial City covers just over 1,000 square kilometres on the Gulf coast of the Eastern Province and is managed by the Royal Commission for Jubail and Yanbu, established in 1975. It houses SABIC plants, the SATORP and SASREF refineries and the Sadara chemical complex, so classified areas are widespread. If you are specifying an intrinsically safe mobile phone for Jubail Industrial City, 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 Jubail Industrial City: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |

| Where it applies | Jubail Industrial City: Storage and loading terminals, Port bulk handling, Utilities and gas processing | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Jubail. 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.
The city has two seaports, the Jubail Commercial Seaport and the King Fahd Industrial Seaport.
Hot desert climate with summer temperatures that can exceed 50 C.
The Royal Commission's chairman's office is in Riyadh, with separate directorates general in Jubail and Yanbu, so city-level services are run locally while plants set their own rules.
The city hosts what is described as the world's largest independent water and power project, producing about 2,743.6 MW of electricity and 800,000 cubic metres of water a day.
Associated gas from oil extraction is collected and processed by Aramco and piped to Jubail and Yanbu as petrochemical feedstock, so gas-handling and pipeline areas feed the plants.
Dammam's airport terminal is about 60 km by road from the Jubail suburbs, 80 km from the city centre and 100 km from the Royal Commission neighbourhoods.
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 Jubail Industrial City. Rounds across process units, storage and loading terminals, and port bulk handling can be long. A handheld intrinsically safe handset lets an operator log readings, take photos and communicate without leaving the area. The IS-04Z1 is designed for Zone 1 use of this kind, with a 4,000 mAh battery for extended shifts.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.
Likely candidates are refinery process units, petrochemical and chemical plants, storage and loading terminals, port bulk handling. 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.
Many. The Royal Commission plans and runs the industrial city, but chemical, refining, power and port companies operate their own plants under their own safety and permit rules. Equipment approval for handheld devices is usually decided plant by plant.
Gas-fired power and desalination plants usually include fuel-gas supply areas, so some classified zones are likely. The city's independent water and power project is among the largest in the world, so contractor numbers are high; confirm requirements with the specific plant.
Not automatically. Each plant operator sets its own approved-vendor and permit rules, so approval at one plant does not guarantee acceptance at another. Confirm current requirements with the operator or its contractor for each plant. This applies on top of explosion-protection certification.
