Three major oil pipelines from the east end at Yanbu, which has two ports: Yanbu Commercial Port and King Fahd Industrial Port.
Yanbu Industrial City on the Red Sea coast was established by royal decree in 1975 and is managed by the Royal Commission for Jubail and Yanbu. Saudi Arabia's Communications, Space and Technology Commission handles radio type approval; certificates are renewed every two years and European test documents are accepted. This page explains what to look for in a hazardous area mobile phone for Yanbu Industrial City, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Yanbu 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. A buyer's engineering review is separate from the certificate. 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 | Yanbu Industrial City: Refinery process units, Petrochemical plants, Crude and product storage and loading | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Yanbu. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
Three major oil pipelines from the east end at Yanbu, which has two ports: Yanbu Commercial Port and King Fahd Industrial Port.
Hot desert climate with a July record of 51 C; coastal conditions favour sealed equipment.
Yanbu is the second most populated city in Medina Province after Medina and the second largest Saudi city on the Red Sea after Jeddah, so a local service base exists.
Yanbu has three separate parts about fifteen minutes apart by car: Yanbu Al-Bahr in the north, Yanbu Al-Nakhal inland, and the industrial city in the south with the Royal Commission residential area beside it.
The harbour is about 20 km south of Yanbu and is sheltered from the open sea by an offshore barrier reef running parallel to the coast.
The port handles about 1,800 vessels and over 84 million tonnes of cargo a year, including crude oil, so marine and jetty work is continuous.
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 Yanbu Industrial City. Yanbu's classified areas include refinery process units, petrochemical plants, crude and product storage and loading, and marine terminals. Zone 1 and Zone 21 both appear. The operator of each plant classifies it, not SAMS, so obtain the area drawings from the plant before ordering.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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, petrochemical plants, crude and product storage and loading, marine terminals. 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.
The East-West crude pipeline of about 1,200 km can deliver up to 7 million barrels a day to Yanbu from the Eastern Province. Road and air links also exist, but heavy equipment normally arrives through the port; confirm routing and permits with the client.
Mostly the industrial city in the south, with its refineries and petrochemical plants, and the port about 20 km south of Yanbu town. Yanbu Al-Bahr in the north is the main residential and commercial area, so offices and hotels are separate from the plants.
Yes. With a hot desert climate, a July record of 51 C and a Red Sea coast, sealed equipment is favoured. IP68 helps against dust and splash, but heat and salt exposure should be checked against the datasheet. Ingress protection does not replace the Ex marking needed for classified areas.
